 September and October; Oregon; Vancouver. 



Mr. Grote's type in the British Museum is exactly like my types in 

 Mr. Neum 03 gen's collection and in the National Museum. I am not at 

 all satisfied that there is not a good species such as I have placed in the 

 4- den ta ta series in the "Revision;" but Mr. Grote's type is unquestion- 

 ably like my infelix and my name sinks. The species is an excessively 

 variable one, and its exact limits are scarcely defined as yet. 



C. islandica Stgr. 

 1857. Stgr., Stett. Ent. Zeit., 1857, 232, Agrotis. 



HABITAT. Iceland. 



A good series of this species is in Staudinger's collection, and both 

 sexes are also represented in the museum at Berlin. Like the surround- 

 ing species, this is extremely variable, resembling both obeliscoides and 

 tessellata. The maculatiou is perhaps more like the latter; but the 

 color contrasts are sharper, and the species as a whole is brighter. I 

 can not understand why Standiuger considered his labradoriensis a 

 variety. He has now associated it in the collection with dissona, which 

 it resembles much more nearly. In the Grote collection in the British 

 Museum is a specimen of opipara labeled islandica by Mr. Grote, and 

 also a California species labeled in the same way. The latter is really 

 much more nearly correct. 



C. colata Grt. 



1881. Grt., Can. Eut., xm, 131, Agrotis. 



HABITAT. Mount Hood, Oregon; Sierra Nevada, California. 

 The type in the British Museum is a 9 without fore legs; but evi- 

 dently belongs here. The median lines are almost obsolete.

HABITAT. Colorado. 



The type is in the British Museum. It is not so near tessellata as 

 the description indicates; but it is very near cola ta so near indeed 

 that except for the ground color there is little difference. It will prob- 

 ably result eventually that the two are identical. Since my return 

 from England, Mr. Bruce has sent me this species for identification.
