Egg.—Sub-ovid, boradest on lower third, the base flattened; covered with a very slight rhomboidal network over the upper third, with low knobs at the angles; on the middle the network is still more slight, but the knobs are distinct, and on the lower third the knobs are minute and unconnected by lines; summit flattened, concave; the micropyle in centre of very fine network without knobs; colour bone-white. Duration of this stage about 20 days.

The following is a list of the entomological works of Dr. C. Zimmermann:-

1. Monographie der Carabiden, Erstes Stueck, Berlin and Halle, 1831, 8vo., pp. 8 and 76, contains the family Zabroides, five genera, with twenty-six species; review in Oken Isis, 1832, vol v., p. 539, vol. x, p. 1117; extraced in Silbermann Revue, 1833, T.I., p., 45–47. The author's copy belongs to the library of the museum.

There are two kinds of caterpillars which every year commit serious depredations in our Canadian apple orchards, although they by no means confine their attentions to that tree. These are the larvæ of the American and Forest Lackey Moths, two species of brown moths which frequently fly into houses at night during July, and draw attention by their headlong, reckless flight, dashing themselves against the ceiling and the walls, and very often finishing up by getting into the lamp chimney.

Larva.—Elliptical and much flattened, the sides rising slightly to two dorsal ridges, only a little elevated, these ridges diverging somewhat towards the anterior and posterior portions of the body. Around the outline of the body is a series of flattened pointed projections forthe last eight segments, furnished on their sides with fine, short hair. These projections occur on each segment after the fith, the two on the last segment some what longer than the others, and directed nearly straight backwards.

We ar glad to learn that Mr. John B. Smith, of the National Museum, Washington, has been appointed State Entomologist of New Jersey. He will enter upon his new duties on the first of April, and will reside at New Brunswick, N. J. While we congratulate the State upon securing the services of so eminenlty capable an entomologist, we trust that Mr. Smith will find his new work congenial and satisfactory, and its accessories lucrative and comfortable.
