In my article in Canadian Entomologist, 1893, pp. 7–8, as also in my previous note in Science, Vol. XIX., 1882, p. 320, I stateed that Hyalt and Arms were the first to point out that the Diptera were the most highly specialized insects, and consequently to be considered the highest in rank. It should be noted, however, that the same idea was advanced at the same time by the renowned insect anatomist, Mr. B. T. Lowne, well known for his work on the anatomy, etc., of the blow-fly.

The “Revision of the Genus Cucllia,” by Prof. Smith, in Proc. U.S. Nat. Mus., XV., pp. 33.et.seq., raises the number of described North American species sto 14, and is an interesting addition to the knowledge of our Noctuidœ. Larger collections from the west have come to hand since my study of the species and have admitted of fuller comparisons. Although the species of Cucullia are not among the commonest Owlet Moths and seem to fall less easily a prey to the collector's efforts than those of many other genera, still we may conclude that the above figures give, at least approximately, the N.American representation of the genus.

The following table contains all the species of Psilocephala known to me as occurring in America, north of Mexico, with the addition of one species form Jamaica, West indies.

For a specimen of this most interesting moth I am indebted to Mrs. Slosson, and after an examination of ti I am unable to find any Bombycine characters, except the heavily pectinated antennæ. In Prof. Smith's List of Lepidoptera it is placed in the Liparidæ between Artaxa and Lagoa, though it bears no resemblance to these moths except in the shape of the antennæ. It has also been regarded as allied to the Cochliopodidæ.

Antennæ, filiform, brown; number of joints, twenty-seven; scape, large, ovate, pale yellow beneath. Eyes naked, large and prominent, dark rosy brown. Clypesu, labrum, mandibles and palpi pale yellow. The lower portions of the epicranium are of the same colour. The occiput is black, smooth and glossy. Mesothorax highly convex, black, sparsely set with short, pale-brown, retrose hairs. Scutellum elevated. Tegulæ yellow. The under parts of thorax amber-coloured, as are also the legs, with the exception of the tarsi and parts of the tibiæ of teh hindmost pair, which are brown.

Among the species heretofore referred to the genus Erax is a small group in which the first submarginal cell is divided by an oblique cross vein into two cells. The venation is similar to that of the genus promachus, except that the foremost of the two apical submarginal cells is shorter, and teh third vein curves forward to the costa before the apex of the wing, instead of curving backward to the hind margin beyond the apex.

When Dr. J. A, Lintner prepared his first annual report in 1882, he, with the aid of Drs. Hagen and Le Conte, failed to discover any record of the clover-destroying habit of this species in Europe, and it was supposed at that time that this was a newly acquired habit, and occurring only in this country.

One hot afternoon in the early part of August, 1893, while out collecting, I found a large web of the Fall Web-Worm (Hyphantriacunea, Drury), on a young apple tree. Reaching up to cut off the twigs to which the web was attached, my attention was attarcted by an unusual disturbance among the immates of the web. Closer insepection revealed the fact that a medium-sized Ichneumon fly had intruded within the family circle, and was proving herself a most unwelcome visitor. Tearing into the web with her feet she would force her way along until she arrived under the skeletonized leaves upon which the larvæ were resting and through which they were plainly visible.

In a short paper publihsed in the Trans. Kans. Acad. Sci., Vol. XIII., on the occurrence, in a single restirced locality in Arizona, of a species of Micropeza, I gave a very brief resumé of the food-habits of some of the better known families of Acalyptrate, Muscidæ, with the view of suggesting the possible habit of the species there considered. This prompted me later to bring together all avialble notes on the subject. As these small flies are of much economic importance, both as being injurious and benefical, I have left that a quite compelte summary of their larval food-habits would be of much use to the working entomologist, besides being of no little importance to those who may be making a special study of the diptera.

In the same leaves of Populus angustifolia in which were found the tenthredinid (lepidopterous?) leaf-miners,* in the Canada Alamosa, northern Sierra county, N. Mex., in June, 1892, there were also found speciemns of a very distinct leaf-miner. It bears of striking resemblance to the leafminer of the vine found in the Mesilla valley of the Rio Grande. It possesses the sucker-like mouth of that miner. After being mounted in glycerine on a slide for several days, however, the outer portion of the distended sucker-like organ became transparent, exposing within what appear to be two stout rounded mandibles with teeth on their inner edges.

The family Phalangidæ is readily seperable from the other families of Phalangida by having but one simple (not compound) claw at the end of each tarsus and having a claw af the end of palpus.

The one most commonly met with is S. tipuliformis, and is to be found sunning itself on the leaves of the currant bushes at the time when the fruit is about two-thirds grown, and on a bright sunny morning about 10 o'clock, or afternoon about 4 o'clock, one can easily take from six to twelve in one or two hours. Once I found them assembling, and took some thirty or forty in a very short time. It is a little difficult to procure the larvæ, as they feed in the two-year-old wood, and, as this is the fruitproducing part, it is better not to cut it while the owner is about, and when you can cut, I have found so many blanks that the bushes have suffered more than the gain warranted.

Truly wonderful is the adaptability of some individuals when placed under circumstances tending to diminish the reproduction of their race. Desrious of raising larvæ of Papilio philenor, I planted two years ago five vines of Dutchman's Pipe (Aristolochia sipho) in my back yard, which in the summer of the present year (1892) covered a wall and fence 16x7 feet with luxuriant foliage.

During the last two years a considerable number of rather small lepidopterous larvæ have been found on alfalfa (Medicago sativa) in Southern New Mexico. In the material collected there are nine distinct species represented. None of them have been bred. These larvæ are of considerable economic importance, as they occasion a certain amount of injury to the alfalfa crop, which is the surest and most paying crop of the Mesilla valley.

In the collection of the Bremen Museum are a number of NoctuidŒ CatocalinŒ brought by Norwich, many years ago, from the vicinity of Savannah, Georgia, and belonging to species for the most part new to me. Nearly all are now identified by me as described by Guenée in the Species General, and their notice here can hardly fail to be of interest. I have previously remarked upon the fact that, as we progress southwardly, we are met by an increase in the number of species of Catocaline Owlet Moths, while the NoctuinŒ, or typical NoctuidŒ, diminish; the metropolis of the former seems to lie in the Tropical, of the latter in the North Temperate Zone.

A round, white, woolly gall was found on stems of Bigelovia (sp. probably graveolens)in several localities in western New Mexico the past summer, from June 19 to 22. Those found June 19 were old galls, and were met with near Luera Spring, in Socorro county. On June 21 the fresh galls were found in numbers near Gallo Spring. Sometimes two or three were found near each other on the same stem or twig of the plant, and in one case three galls were found joined together, forming a triple gall. On June 22 they were found extremely common west of Apache Spring, thus seeming to increase in number in a westerly direction, as did also the patches of Bigelovia, every plant of which was full of them.
