through that month, and even took an unusually fine larva as late as the 2rd of 
October, The young larva of S. Ligustri is, I believe, seldom found. I have been 
disappointed in obtaining it myself, having tried both beating and searching in 
localities where I had no difficulty afterwards in obtaining the nearly adult larva. Tf, 
as has been supposed, its mode of concealment is merely to retire to the interior of the 
bush, it should be discovered by one or other of those methods. I am inclined to 
infer that it descends to the surface of the ground during the day—John R. 8S.

Larva of Cherocampa Porcellus near Chelsea.—I found three larve of Cherocampa 
Porcellus? feeding upon Galium aparine? in a lane on the_outskirts of Chelsea, at the 
beginning of last August. When full grown it changes to a pupa on the surface of 
the ground, forming a slight cocoon of considerable size by drawing together the 
withered stems of the plant.—Jd, 
Statices versus Geryon. By the Rev. Epwarp Horton, M.A. 
AurHovuen I agree with Dr. Staudinger (Zool. 8403) that “a young 
naturalist should, if possible, avoid” asserting that two similar insects 
are of the same species because they happen to be similar, I think that 
older naturalists are not without danger of falling into the opposite 
error, that of making out similar insects to be of different species. 
Perhaps the popularity of the Divorce Court, under the able adminis- 
tration of the late Sir Cresswell Cresswell, is beginning to have its 
effect in entomological quarters; for the case of Statices v. Geryon 
has been decided in a way which threatens a facility in dissolving the 
specific tie very dangerous at a time, when the very existence of that 
tie is called in question. I am no lawyer, but I think that the heading 
of this important case should rather be Statices v. Statices than 
Statices v. Geryon; and, with all respect to the judicial bench and the 
jury, who may have weighty reasons, not known to the world, for their 
decision, I have taken upon myself to review the evidence, as it has 
appeared in print in the ‘ Zoologist.’. The earliest notice I can find is 
at p. 8403, where Mr. Newman quotes a long passage from Dr. 
Staudinger’s Monograph of the genus Ino, published in 1862. The 
first statement in that extract will be accepted by all who are 
acquainted with the two insects under consideration: “This species 
(Geryon) is altogether less than I. Statices.” 
- The next assertion that “there is scarcely any difference between 
the two sexes” of I. Geryon in size, does not agree with my observa- 
tions. From the numerous specimens that I have examined, I should 
say that there is a noticeable difference, though not perhaps quite so 
great as in I. Statices. Individuals of each sex differ considerably
