TBE CANADIAN ENTOMOLOGIST. 333 



and more str'gate, having in particular a faint grayish streak in submedian 

 interspace, joining the median lines, which seems to be lacking in all 

 unicolor at present under examination. The secondaries are even, and 

 un'formly darker. Structurally there is a difference in the abdomen of the 

 female, that oi luiicolor having a pair of sublateral foveas, or plates near 

 the extremity, which are lacking in havike. It is by this character that 

 Sir George Hampson separates them in the tables. 



2 2 1. Chorizagrotis auxiliaris Grt. — The type in the British Museum 

 is a female from Colorado, and has blue-gray collir and costa, being the 

 form I had previously standing as intro/erens, and is much like the speci- 

 men figured by Holland as intro/erens. Sorror Smith (usually written 

 soror, though not as originally published) seems to me exactly the same 

 form, though the separation seems to have been based on the form of 

 male genitalia. Sorror was described from two Montana females from 

 the Hulst collection. There is a type at Washington, and, according to 

 my notes, another in the Brooklyn Museum labelled " Arizona," but as 

 this is at variance with the description, my note needs verifying. 



2 2 2. C. intro/erens Grt. — The type in the British Museum is a male 

 from Texas with yellowish collar and costa, and is the auxiliaris of 

 Smith's monograph and my previous notes, with which I had associated the 

 females of the series with the clearest and most whitish costa. The type is 

 the actual specimen figured by Sir George Hampson as auxiliaris, of 

 which he makes it the male, probably correctly. In the figure the costa 

 should really be more even. 



223. C, agrestis Grt. — The type, also in the British Museum, is a 

 female from Colorado, and is the pale red-brown even-coloured form that 

 I had standing as typical inconcinna. The more variegated and distinctly 

 maculate forms formerly held by me as agrestis seem correctly associated 

 with this, and I have no reason for suspecting that the Calgary, or any 

 Canadian material that I have seen, includes two species. Nor have I 

 yet succeeded in drawing any line between agrestis, intro/ereiis and 

 auxiliaris, and suspect that they are all one. A itsY years ago I confined 

 a large number of females over various herbage to try and induce them to 

 lay, but without success. 



[224. C. inconcinna Harvey. — This name had better be erased from 

 the Alberta list, the series I had so referred being, as above stated, typical 

 agrestis. The type of inconcinna in the British Museum is a male from
