The very extensive collection of galls from the U. S. presented to the Museum in 1870 by Baron von Osten Sacken, contains all his types. There are 138 different galls of Cynipidæ, gall flies 56 species, guest flies 23 species, parasites 66 species, and from Dr. Reinhard 38 types of European Cynipidæ. Further galls of other insects 121 species (Diptera 70, Hemiptera 30, etc.); the types of B. D. Walsh, galls of Salix, 13 species. To these were later added by the Baron his types of Colorado galls, 12 species, and those of California, 15 species. The permanent aim to enlarge this excellent collection has met with success. The prominent additions from Europe are 88 species from Mr. Brischke, in Danzig, Prussia, and 96 types of oak galls from Prof. G. Mayr, in Vienna, Austria, and 18 types of mite galls from Dr. Thomas. The additions of N. Am. galls are very numerous; prominent among them are large additions from California, Washington Terr., and Mexico.

The following notes on the habits of several insects are from a record of entomological observations kept during the past four years, and although imperfect, they may serve as a hint to others to pursue observations in the directions indicated.

During the past season few unusual specimens were taken and very few notes made. Diurnal Lepidoptera (with the single exception of P. cardui, which had been rare for some years) were unusually scarce. Pieris rapœ is becoming less numerous every year, owing, probably, to its many parasites. Moths were not so abundant as usual, and the only capture worthy of notice was the re-occurrence of Aletia xylina Say (the cotton-worm moth), a single good fresh specimen of which was taken October 26th, in the woods, among leaves near a butternut tree.

Several specimens of the larva of this insect were received on the 8th of July, 1884, from Mr. Acton Burrows, Deputy Minister of Agriculture, Winnipeg, Manitoba. They were reported as seriously injuring vegetables and field crops in that Province.

Length, one and half to one and three quarter inches.

Head medium in size, yellowish brown, with a polished surface, dotted and streaked with dark brown.

Form nearly cylindrical, tapering a little towards the head.

I have recently obtained this elegant Phalenid from its larva, which feeds on the wild red cherry (Prunus Pennsylvanica). July 8, several nearly mature caterpillars were discovered on the twigs of their foodplant. They were an inch in length; color dull red, closely simulating the bark of the branches; and to more effectually conceal themselves by mimicry, they hold on, when at rest, by their pro-legs only, the body standing out like a short branch, or they hold to a leaf by their fore legs, making their bodies appear like a petiole.

Pamphila myus, n. sp.

Male.—Expanse .95 of an inch. Upper surface dark olivaceous brown, with a slight vinous reflection, about the same shade as cernes, which it much resembles. The primaries have the discal cell and the area in front of the cell like cernes, heavily washed with yellow of a little darker shade than that species, the same color ectending beyond the cell along the costal area three fourths the distance from the base to the outer margin (as the wings are spread); below the cell the same shade of yellow extends along the median vein the same distance, the area below this to the margin rather heavily sprinkled with yellow scales, except the space beyond the lower half of the stigma. This varies but little from the yellow of cernes. In cernes there is a quadrate sinus of the terminal dark brown of the wing dipping into the yellow beyond the cell, coming up to the cross vein. In this species the sinus is of the same width, but extends inward above the median vein, ending in a point half way to the base of the wing. The stigma is black, narrow, oblique, entire, though constricted below the middle, shorter than in cernes, does not reach the submedian below, and the upper end only reaches the second branch of the median, while in cernes it passes beyond this veinule, the lower third bent a little towards the base, in width not more than half as wide as in cernes; below the stigma an oblong patch of blackish scales that are bronzy in certain lights. Secondaries sprinkled with yellow scales, the inner half with yellowish hairs that are less olivaceous than in cernes.

Being on a visit to Ridgeway in July, 1882, when out one day with Mr. Kilman on a hunt, as I beat a high branch for beetles, a large moth new to me dropped into my umbrella. Having secured it in my poison bottle and remarked that I must now find its mate, another stroke, and sure enough, I got it. I took a third at that time sitting on the trunk of a tree, which I left with Mr. Kilman. The following season he took one or two, and last spring he found some cdhrysalids under moss, from which he raised a pair. On visiting Prof. Kellicott, of Buffalo, Mr. Kilman left with him an example, that he might obtain its name. Mr. Kilman now writes to me that Prof. Kellicott has identified it as the Apatelodes angelica of Grote's Check List, with hyalinopunctata Pack as a synonym, which latter name would have been more appropriate. Prof. Kellicott conveys the information that it is described and figured in the Proc. of the Ent. Soc. of Phil., iii., 322, plate iv., fig. 1. It is quite a fine moth.

The condition in which Coleoptera pass the winter is a subject on which there are in American literature but few recorded observations. That no species hibernates in the egg stage is highly probable, though in all the others it occurs—some wintering in the perfect state alone, some in the larva and the imago condition, and others as larva and pupa.

Many of the species appear to make some preparation, retiring to situations that will more or less protect them from intense cold; others seem to have power to survive without any practical protection, as Lixus concavus and Megilla maculata, to be mentioned further on.
