EGG.—Conical, the base flattened, the top rounded; ribbed vertically, the ribs being either 8 or 9 in number; these rise from the surface at about one third distance from base, increase in elevation graduaily, and end at the summit about the little flattened space which contains the micropyle, with its rosette of minute reticulations; the ribs meet the summit at an angle of about 45°; in the last part of their course they are thin, and are grooved on both sides to the surface; between them are many fine horizontal striæ; color green. Duration of this stage probably 4 or 5 days.

There is in the study of Entomology a fascination and delight that captivates the imagination, and renders the enthusiast liable to construct theories based upon such slender foundations that they fail to reach the dignity of assured facts. This, I think, may be said of much that has been written concerning the habits of this beetle. The record which I have thought proper to make relates to veritable facts, but whether in the particular instance referred to they are to be regarded as extraordinary and not of common occurrence, may be a problem yet to be solved. I trust that in offering this paper I may not be thought presumptuous in differing with so distinguished Entomologists as Drs. Harris and Fitch, yet as my observations do not bear out the conclusions which they have reached, and apprehending that the best interests of the science are served by that record or enquiry which relates to the discovery of facts, I make no apology to these fathers in the science for transcribing in relation to this subject views somewhat dissimilar to theirs.

I have never seen this species, and give the substance of the very detailed description of Mr. Lucas.
