26 THE CANADIAN ENTOMOLOGIST.

£. The specimen is much larger than A. Hollanani, hind wings 

 paler and the ornamentation differs in detail, with a general great simil- 

 arity. The resemblance to the Coloradian Oncocnemis Chandleri is so 

 perfect that they can hardly be separated. Nevertheless, the Oncocnemis 

 has unarmed tibiae, the fore tibiae alone with a terminal spine, whereas 

 the Agrotis has all the tibiae armed, the fore tibiae with a double row of 

 spines. The insect is also more whitish and larger. The antennae are 

 simple, the^eyes naked and lashed. Whitish gray, with longitudinal 

 interspaceal striations of a darker tint, more prominent terminally. The 

 stigmata are united, the decumbent open orbicular fusing with the reni- 

 form, so that a flask-shaped figure is produced longitudinally on the cell.. 

 A narrow black basal ray ; a terminal series of blackish dots ; the nervules 

 accentuated. Hind wings whitish, soiled with fuscous ; the nervures 

 marked. Body pale, with a black line on the collar and inner edging to 

 the tegulae. Palpi with the middle joint dark at the sides. Beneath 

 whitish, without markings. Exp. 40 m. m. California, Mr. Hy. Edwards, 

 No. 2256.

The Californian specimens do not seem to me to belong to a different 

 species. The character of the open orbicular is variable, as in one speci- 

 men it is shaped as in my Eastern specimens. The collar is brown in all 

 my remaining Californian specimens. I forwarded Californian examples 

 of this species to Mr. Morrison with this determination, although this 

 circumstance is not mentioned (as should have been done) in Mr. Mor- 

 rison's paper. This is a very variable species ; one Californian specimen 

 has the forewings unicolorous pale brown, without markings. Others have 

 no trace of the claviform, and the median space is not shaded with black, 

 showing that Mr. Morrison's characters for his species are invalid.
