Siivery white; apical half of the anterior wings pale golden; there is a long, pale golden basal streak situated just within the costal margin, and strongly dark margined towards the dorsal margin, and extending to the pale golden of the apacial portion of the wing. In the pale golden portion are four silvery dorsal streaks, all dark margined internally ; the first dorsal and first costal streaks opposite, and both very oblique, and almost confluent in the middle of the wing; second dorsa1 opposite the second costal.

The following species, which have been described by Drs. Packard and Fitch, I have not met with. But for the convenience of those who may not have access to the writings of these gentleman, I condense the fol1owing account:–

1. L. Argentifimbriella Clem. has been already mentioned at p. 57. It mines the under surface of leaves of the Chestnut oak and must resemble L. caryae-albella or L. lucidicostella. At p. 57, ante, it is suggested that L. querci-albella fitch may be the same insect. Dr. Fitch states that it mines the leaves of the White and chestnut Oaks indifferently. But Dr. Clemens says that Argentifimbriella makes a tent mine on the under side, has a cylindrical larva, and pupales suspended in a thin web in the mine like L. lucidicostella.

Figures Nos. 25,26 and 27 represent the caterpillar, chrysalis, and perfect insect of the grape-vine sphinx, Chærocampa pampinatrix. The young larvæ varying in color from green to pale lilac or red, are now (August 1st) very common, and may be easily recognised by reference to the figure: for although the ground-tint of the body may vary.

Palpi white : face opalescent or silvery, according to the light : antennæ maroon-brown, silvery towards the apex: tuft maroon-brown : thorax of a shining metallic lustre, in some lights opalescent : a streak of the same hue crosses the extreme base of the wings, is continued for a short distance along the dorsal margin, and thence curves obliquely across the wing again to the costal margin, enclosing a maroon-brown patch upon the costa, and being narrowly margined behind with dark maroon, beyond which the wing is bright golden to the apex.

I Give herewith the conclusion to my experiments with Ajax and its varieties. The Telamonidas larva spoken of in my communication of 27th Feb. (vol. ii., p. 163) as having lived over the winter, on the 1st of April, 1871, produced male Telamonidas(all the rest had yielded Marcellus in 1870). The Marcellus larvæ were mostly lost at the burning of my house in February, but one was saved and yielded Telamonidas female on the 10th of April, 1871.

The gooseberry saw fly, Nematus Ventricosus. The season of warmth and growth having opened this year early, this never-failing pest has put in its appearance also in advance of previous years; as early as the 23rd of April I found the insect on the wing preparing to deposit its eggs as soon as the foliage was sufficiently expanded. Our last number contained an enlarged figure of the fly. (See fig. 4.) We now give a representation of the larva in its natural position, feeding on the leaves

Three specimens of this larva were taken sept. 16th, feeding on Oak.

Length, 1.30 in.; cylindrical.

Head large, slightly bilobed, black with a faint white streak down the front, as far as the middle, where it becomes forked, a branch going towards each of the palpi. Mnadibles black, palpi white at base, tipped with black.

Face, palpi, under surface and legs silvery-white, the legs marked on their anterior surface with golden and brownish spots and bands: tuft, white, golden at the sides ; antennæ silvery-white beneath, above goldenbrown faintly annulate with whitish : thorax and anterior wings bright golden ; upon the wings is a short snow-white median basal streak strongly dark-margined behind and within. (Sometimes the anterior margin and sides of the thorax are also white)

To make the Entomologist more interesting and useful to fruit-growers, it is intended to devote a page of every number issued during the summer season to giving practical hints in reference to insects whose times of appearance may be near at hand, with a condensed summary of such means and remedies as have been found most serviceable in lessening the numbers of such as are injurious. We shall be glad to receive communications from fruit-growers relating to any new insect pests occurring in their neighbourhood.

All of my specimens have a very pronounccd though rather short white dorso-basal streak, which is sometimes continuous with a longitudinal median white streak upon the thorax, and in all of them the median basal streak is continuous with a white line across the anterior margin of the thorax, which is extended backwards over the tegulae. The dorso-basal streak and the markings of the thorax and tegulae are not mentioned by Dr. Clemens.

It is not, I believe, generally known that, closely as these two insects resemble each other in the larval and pupal states, they may, nevertheless, be readily and invariably distinguished by the constant differences in the anterior horns of the former and in the hump of the latter. I was fortunate enough, the present summer, to have several larvæ of each species feeding, as also several pupæ of each hanging, at one and the same time ; and with the exception of the characters here given, I do not think there are any other distinguishing features to be relied upon.

[145] 194. Campylus Denticornis, Kirby. – Length of body 6 lines. Taken in Canada by Dr. Bigsby.

This is the American representative of C. mesomelas, from which it is sufficiently distinguished by its toothed antennae and longer prothorax. Body linear, black, hairy with pale decumbent hairs. Head punctured ; antennae longer than the prothorax, filiform, with all the joints, except the scape, pedicel, and terminal one, terminating at their internal extremity in a prominent tooth, less conspicuous in the two lower ones ; upper-lip, and nose which is reflexed and overhangs the mouth, yellow : prothorax channelled, punctured, quadrangular, with the anterior angles rounded, and the posterior diverging and terminating in a sharp tooth or prominence ; sides rather wavy ; limb yellow : scutellum subcordate : elytra minutely and thickly punctured, slightly furrowed, furrows thickly punctured; marked with a narrow yellow, stripe which does not reach the apex ; there is also a short yellow streak on the shoulders : base of the tibiae, claw-point of the tarsi, and claws, yellow. [“Lake Superior, Maine and Pennsylvania” (Le Conte). We have specimens taken in the neighborhood of Ottawa, Ont.]

Specimens of a nearly black geometric larva which afterwards proved to belong to this species, were taken last year on the 15th of July on currant and gooseberry bushes, on which they were feeding. They fed on the foliage of the black currant as well as of the red, and in fact seemed to prefer it.

When first taken they answered to the following description:

Length 45 in. Body tapering a little anteriorly, thicker on middle and hind segments.

The larva of this beautiful geometric moth is dark brown, and feeds on beech. The specimens, from which the subjoined description was made, were taken on the 10th of September, by beating the branches of some beech trees over an umbrella.

Length one inch, body cylindrical.

Head medium sized, bilobed, dark brown, with two bluish-white lines in front; mandibles paler.

Body above, dark brown, with a row of dull white dots on each side, one or two on each segment, most prominent from fifth to eighth segments inclusive, less distinct towards each extremity.

Sometime during the latter part of July last, while wandering about the outskirts of a large potato patch, and examining the damage caused by the Coloroado beetle. I found on the vines the larva of a beetle belonging tothe family of Coccinellidæ or Lady Birds. The insect was new to me and although there were no larvaæ of the Colorado beetle in the immediate vicinity, yet I was in hope that I had discovered a new enemy of our abominable pest. To test the question more at leisure, I took my newly-found treasure home, and placed it in a box, wherein were numerous specimens of Colorado larvæ in all stages, from the diabolical looking little monster just hatched from the egg, to the full-grown, fat, and repulsive larva dragging its bloated body slowly about in search of some convenient place to undergo the transformation into the pupal state.
