Cataclysta Robinsonii Grote. ♂ ♀ I refer this species to Lederer's Section C.: veins 8 and 5 of the secondaries present. primaries bright golden brown. The median whitish grey space is tolerably narrow and well defined; inwardly bounded by the outwardly arcuate white transverse anterior line; outwardly by the white transverse posterior line which is angulated on the m. nervuies. Both the lines are a little uneven. From the distinct ans regularly arcuate white transverse posterior line to the base of the wing, the surface is entirely golden brown.

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.

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.

167. Byrrhus Cyclophorus Kirby.–Length of body 3¼ lines.One specimen only taken.

Body underneath and limbs dull feriuginous, above black with some cinerous hairs intermixed. Antennae piceous: elytra with two deep black subinterrupted stripes, and inscribed in the middle with traces of a circle formed of pale, or cinercous hairs, common to both. The circle is probably more distinct in recent specimens. [Taken at Grimsby, Ont., by Mr. Pettit, and at Toronto by Mr. Couper; north shore of Lake Superior by Agassiz's Expedition.]

Agrotis repressus, Gtote. Hind tibiae with two, middle tibiae with one pair of spurs; fore legs unarmed. Palpi prominent, porrect; 3rd joint elongated. Body somewhat flattened, much as in A. clandestina. Squamation lustrous, silky. Unicolorous pale testaceous or greyish brown. Fore wintgs and thorax concolorous the first are without markings, except a short dark dash on the cel1 in place of the orbicular, and two similar superposed marks at the extremity of the cell, in place of the reniform spot. Three pale ante-apical dots on costa. veins subobsoletely marked with darker scales.

In the previous paper Mr. Grote describes a new species of Agrotis, under the name of depressus, which was sent him from my collection some time ago; he also refers to Agrotis clandestina as received from me. This latter species was first determined for me by Mr. C. V. Riley, of St. Louis, Mo., and subsequently by Francis Walker, Esq., of the British Museum, Mr. Riley has figured and described the larva in his first report on ,“The Noxious Insects of Missouri,” p. 79, and my own description was published in the present volume of the Can. Ent., p. 35.
