Egg.—Globular, a little flattened at base, smooth; color orange yellow. Duration of this period, 24 days.

Young Larva.—Length .08 of an inch. Color pale brownish green. Head and a small cervical shield jet black. Each segment has about six blackish tubercles from which arise rather long gray hairs, the dorsal tubercles on segments 5 and 12 a little more prominent than the others. Duration of this period, 3 days.

After First Moult.—Length .14 of an inch. Color pale yellowish green. Head black, as also a plate and a small spot on the top of the second segment. To each segment six purplish black slightly tubercular spots; those on the dorsum faint except those on 5 and 12, which are prominent, each pair confluent; a few hairs from each spot. Thoracic feet black. Duration of this period, 4 days.

The transformation of a grovelling worm to the glory that attaches to the winged aspirant of the heavens, has won for this insect from remote antiquity the appellation of Spirit or Soul, as typical of the resurrected human body. There is, I think, good reason to believe that the root meaning of the word Butterfly dates back to early Egyptian history, and as a hieroglyphic it is synonymous as representing the qualities of completeness and perfection which characterize the soul. I have supposed that it might serve the interest of this journal to record such historical gleanings bearing upon this subject as have come within my reach. It is said that in Yorkshire in England, the country folk call the night-flying white moths, Souls. This restricted application of the term very forcibly expresses what had been traditionally received by these people, and which they unwittingly have applied to certain white winged species. The English word Moth is said to be the Egyptian MUT or MAT. MAT is to pass; MUT to die; MATT, unfold, unwind, open, as the chrysalis entered the winged state and passed. The winged thing was a symbol of the Soul; it appears in the hieroglyphics as the Moth or Butterfly.

Hololepta fossularis Say. The habitatio of this insect is usually under locust bark in the first stages of decay, a fact so well known that collectors would look for it in no other place. But last summer I found a number of them under the bark of Ulmus fulva (slippery elm), the odor of which in the same state of decomposition is as rank as that of Robinia. With them were several H. lucida. The individuals of these two species so approximate as in some examples to be scarcely separable; and indeed there is a reasonable doubt whether any of them are instinctively conscious of being specifically different.

Genus Synairema, Hartig.

This genus was detached from Tenthredo by Hartig in 1837, for an insect described in 1793 by Panzer, under the name of Tenthredo rubi, found in Germany, Sweden, France, Tyrol, &c. In 1849, Bremi described a new species found in Helvetia, which he named S. alpina. It has not yet been recorded as met with in America.

Synairema differs only from Tenthredo by its lanceolate cell, which is largely contracted in the middle, while in the last it is separated by a straight nervule.

The object of giving this list in its present imperfect form is to call the attention of our Entomologists to this greatly neglected order of insects, and as most of the families are still in an unworked condition, to call especial attention to them; of course, the named species represent only about one fourth of all the species taken by me during my three years collecting, and were mostly taken in Fairmount Park, and a few at Delanco, N. J.

If a few of our many Entomologists would turn their attention to the Diptera, they would be sure to find an interesting and very wide field, in fact there would be room enough for nearly a dozen systematic workers in this order.

Crambus zeellus, n. s.

expanse of wings, from 18 to 24 m. m.

Palpi, head and thorax, pale leaden gray. The labial palpi extend forward as far as the length of the head and thorax. The maxillary palpi are as long as the head.
