Abb., it seems to me to belong to the same group as Bemas^ 

 — at any rate to the Artisice. Scrihonia certauily belongs to 

 them, and in its own group symbolizes Zeuzera. Dryocampa 

 must belong not to the Bomhycidce^ but to the Notodontidce. 



You will see on the other side a larva, larva case, pupa and 

 imago, of an insect allied to, but distinct from, Tliyridojyteryx 

 Steph. The imago is chocolate brown, disk and nervures 

 darker, a trilobate white spot on the upper wing. Feeds on a 

 shrub, I think the 3£espUus cestivalis Walt. ; vide Elliott I, 549. 

 It is figured by Abbot. 



I must say one or two things more. The larva of Lopho- 

 campa proves to me that it is allied to Acontia^ Erebus^ etc., 

 and comes late in the Noctuce. It is a half looper with twelve 

 feet. Abbot has figured, or rather drawn, a species I do not 

 know, small and differently colored. Larva purplish, with 

 orange and yellow spots, feeding on Hibiscus Moscheutos. 



There is one more insect I will mention, and then I have 

 done. It is a Colias, very near to, but smaller than our Edusa. 

 Upper wings deep orange, with a broad black border, in which 

 is one small, round, pale yellow spot near the lower angle. The 

 central black dot as usual. Tinder wing grayish, clouded ex- 

 ternally, with an incomplete blackish margin, and a bright central 

 orange spot. Below, upper wings yellowish, disk orange, one 

 central and four marginal black dots ; lower wings greenish, 

 with a central white spot surrounded by a pale ring. 



HAREIS TO DOUBLEDAY.

The male Oiketicus has the form, etc., of a Zeuzera ; the 

 larva, in form, is not remote from those of the Zeuzeriadce ; and 

 it has the habits of the true spinners, or Bombyciadce. From 

 the latter we pass by means of Megasoma Boisd., to the Atta-
