nearly squarely truncate with a sharp spine like protuberance on each 

 side giving the pupa quite the appearance of the seeds of the common 

 Beggar ticks {Bidens /rondosa). Tliese points are in all cases violet in 

 color. On each side of the pupa edging the wing-cases is a light hne 

 edged in the green specimens with a shade of viokt and in the darkf 

 specimens with dark violet. The pupa is fastened by the tail to 

 slight button of silk, and is also girthed with a threatl of silk aboi 

 the wing cases. Pupated, August 29th. The larva before -S[)inning 

 loosely covers the surface of the leaf or stem witli silk, and the girth often 

 shows individual strands running off to quite a distance, giving the idea 

 that there is tendency towards a slight cocoon. The })Ui)a is very active, 

 wriggling in a lively manner when anvthing touches it. 



Of the pupa Dr. Packard gives a description antl figure Mon. Geom. 

 p. 2i?i^, pl- 13- f- S'2- In the description he speaks c^f the pupa as "flat- 

 tened" which is not true of the 30 or 40 specimens before me. In the 

 figure the ear-like projections aie slightly shorter than in those before me. 

 The imago, which is two-brooded, emerged Sept. yih. 



There is a very considerable interest attaching to this history as it 

 bears upon the position that n^uch discussed species Euphanessa vicndica 

 Walk. Walker, Herrich-Schaefier, and Dr. Packard put it in the Boin- 

 bycidce. I discussed the matter in a paper before the Entomological Club 

 of the A. A. A. S. (Entom. Am., Vol. II, p. 167). and there gave my 

 reasons for believing it a true Geometer. The greatest aberrancy was in 

 the shape of the pupa, and its habit of placing a girth of silk about the 

 wing-cases. I had considered that the moth ought to be catalogued near 

 Ephyra. The history of^. insularia strengthens my opinion that the 

 insect is a true Geometer, and also that I was right in my idea of its 

 place in the Catalogue. The form of the pupa of A. msnlaria very 

 strongly resembles that of ^. mendica, and its hibit of making use of a 

 girth is the same. I am indebted to A. C. Weeks, Esq., for the larvte.

 Eds. Entomologica Americana. — Gentlemen : 



I am open to criticism in saying "Ent. Am." Vol. Ill,- p. 85, that 

 there are two exceptions to Lieut. Casey's observation that the tibia; are 

 unarmed in Stenus when I only adduce one. 



A pupa of Anthonomus pusillus has been discovered in the seed- 

 vessels of Helianihemum Canadetise since my notes were written, proving 

 that the entire transformations take place within the seed vessels as I had 

 supposed. Respectfully, Frederick Blanchard.
