Head light green, around which is a ring of bright fine yellow granulations. Body light green whitish at the dorsal region; a whitish subdorsal line on each side running from caudar horn to third segment, also a dorsal green line running from caudal horn to 3rd segment, where they both become indistinct. Under side and legs chocolate brown, prolegs brack, with a narrow white band near base. Caudal horn thin, slightly curved forward, flanked at base with bright yellow. Stigmata on first, and from third to tenth segments, dark blue. Length about two inches. Larva finely granulated with white. It is found from middle of June to end of July. Of these, some of the earliest larvæ will, after pupating, hatch within about two weeks, (the balance staying over till next spring) which will deposit their eggs and also grow to maturity towards the latter part of September; so that the larvæ may be found almost continually from June to October. The eggs are small, round and green, and hatch in about ten days; they are found on the under side of the leaves of Symphoricarpus, Lonicera (different species), and Triosteum perfoliatum, its food plants.

A curculio new to Canada has appearecl in this locality. Prevailing east winds about Aug. 10th wafted this nerv clover pest to our shores. This beetle, as far as I know, has not been mentioned in the Entomologist. It was introduced from Europe little more than three years ago. Appearing on the eastern seaboard, and taking the continent in the inverse order to the movement of the Colorado Potato Beetle, it is working rapidly westward. Last year no specimens were reported west of Rochester, while in Eastern New York the clover crop was destroyed by this insect. On the date above mentioned it appeared in Buffalo in such numbers that thousands were crushed on the pavements by the feet of passers-by. Simultaneous with this was its appearance in Ridgeway. I picked them from the fences and sidewalks, and found them in the grass on my lawn. Mr. Reinecke could have gathered them by the quart along the lake shore at Buffalo, where they had stranded after being carried by the wind far out upon the water. They have the extraordinary faculty of closing their tracheæ and suspending respiration while in the water, and an hour's sunshine on the sandy beach leaves them none the worse for a good soaking.

The species in the following list were taken in Fairmount Park during the past summer, and mainly during May and June, which is the best time for Syrphidæ; then there are some which only appear in the fall months. Of all families of Diptera the Syrphidæ seem to be better represented in the Park than any other families of this order, perhaps with the exception of the Dolichopodidæ. The Syrphidæ seem to prefer damp and somewhat open woods, especially a small wood that has a small rivulet running through, near the border, and where there are patches of May apple, with the sun shining through the trees on the plants. This only applies to some species, for others prefer the borders of woods, fields, etc. I never found many Syrphidæ in a hot and sandy county, for instance like New Jersey, but what it lacks in Syrphidæ it makes up with the Bombylidæ, for last summer I took about ten species of the latter family in one day, while I only took about seven species the whole summer in Fairmount Park.

Lamesis Westw. Tijdschr. voor Entom. xxvi., p. 67. I would call attention to the possible identity of this genus and Xenorhipis Lec. The figure given by Westwood (pl. 3, fig. 8) certainly bears a very close resemblance to that published by me of Xenorhipis (Trans. Am. Ent. Soc. 1882, pl. iv., fig. 7, 8). If the two should prove identical, the name given by LeConte (Proc. Acad. 1866, p. 384) should have priority.

During the summer of 1882 a few of the ash trees on the college lawn became infested with a Saw-fly worm which for a few days threatened to be quite serious. I made a few trials of London purple on the trees most seriously infested, but before I had gained results from many trees or had completed a study of the larvæ, they suddenly disappeared. So far as my experiments went they showed the London Purple to be a successful remedy and as applicable to these worms as to any of the Saw-Fly group. No adults were observed, and none of the larvæ I had under my observation matured; so the matter necessarily came to a rest.

In the American classification of the Lepidoptera, the Bombycidæ occupy a place between the Zygænidæ and the Noctuidæ. They include a large number of genera and species, and are well represented on this continent. The principal characteristic of the family is that from which it derives its name of Bombycidæ,—or spinners,—the power the caterpillars have of producing a silken fibre, which they use in spinning a cocoon in which to pass the pupa stage of their existence. The Silk-worm moth, Bombyx mori, is the typical species of the family. Some genera, however, do not produce silk in any quantity. They are also remarkable as a family for the imperfectly developed mouth parts in the perfect insect. In nearly all of them the tongue is short, and in some species wanting, and the other parts of the mouth so imperfect that it is not probable the insects feed at all in the perfect state.
