in the cell. The second or middle line is obsolete in one, and reduced to 

 a mere dot in the cell in three or four more. The third is occasionally 

 broken, or very fine and reduced, and in one specimen almost obsolete. 

 A male taken at light by Mr. Hudson on July 20th, 1906, has the 

 secondaries yellow instead of red, slightly tinged with orange centrally. 

 Dr. Fletcher referred it to this species. It is strange that this and the 

 citrinaria above referred to should have been taken on the same night. 



127. Parasemia petrosa Walk. — Had I studied Mr. Bean's article 

 more closely, I should, as suggested by recent correspondence with him, 

 have thus named my species rather than plajitagmis, which does not seem 

 to be properly referable to any known North American form. A form 

 sent me by Dr. Fletcher from Nepigon, Ont., as Selwy7iil Hy. Edvv. 

 ( = ^SiT^^^^^r/ Pack.) differs in some respects from anything yet taken in 

 Alberta either by Mr. Bean or myself, and is, Mr. Bean tells me, claimed 

 to be constant in its locality, and not unlikely distinct.

 food-plant.

132. Acroiiycta canadensis Smith. — There is only one specimen now 

 in my collection which I feel sure is the same species as the type. This 

 is a female dated July 13th, 1899. It is the one previously referred to 

 as labelled "like type" by Prof. Smith, and '"'' lepuscidina Qiw.^' hy Sir 

 George Hampson. The latter determination would probably now be 

 revoked, as he figures a female from Hudson's Bay under ^'canadensis'" as 

 a species. It may be the same as mine, but is not obviously so. The 

 figure does not happen to be a very good one of the specimen. I have 

 re-examined the type, but beyond suggesting that it shows affinities to both 



felina and cretata, I dare form no opinion at present as to its true status. 

 Hampson claims that insiia of Smith and Dyar's " Monograph " is 

 lepusculina Gn., and renames their lepiisciilina as chio7iochroa^ figuring a 

 male from Iowa, but making no type. I mention this to explain the 

 former reference of canadensis to insita by Smith, and to lepusculina by 

 Hampson. Insita Walker appears to have preference over denvera 

 Smith. I have reasons for doubting whether either itisita or lepusculina 

 of Smith and Dyar were pure. 



133. A. cretata Smith. — I took a fine series of this species at treacle, 

 between June 22nd and July i6th, 1909, and its distinctness from ca7ia- 

 densis stands out quite clearly. It was described from one male and two
