THE CANADIAN ENTOMOLOGIST. 29 



is very distinct from C. Tarpcia ; the latter comes nearer to C. C/iryxus, 

 being quite a fulvous species, with blind ocelli on under surface. The 

 band of secondaries also is altogether different in outline '' ; and Mr. 

 Butler giv;s me a drawing of the wing and band. His drawing and 

 description in all points named agree with what Mr. Scudder formerly 

 described as C. Calais, from a single female taken by Mr. Drexler 20 

 years ago, at Rupert House, Hudson's Bay, and on carefully comparing 

 this (which remains unique in my collection) with a series of C. Chryxus 

 from the Rocky Mts., I see that it is a distinct species, and not Chryxus, 

 as of late I had assumed. 



NOTE ON LIMENITIS URSULA. 



BY W. H. EDWARDS. 



In my paper on L. Arthemis and its alleged second brood, in Dec, 

 1 88 1, I stated that some caterpillars of L. Ursula did go on to chrysalis 

 and butterfly late in the year, in Ohio, though others of same lot went into 

 their hibernacula when half grown ; and that I had dissected one female 

 Ursiila which emerged in September last, and could discover no signs of 

 eggs, or at any rate, there were no formed eggs. Also that I had sent a 

 second female of same lot to Prof Minot for examination. I now have 

 his report, as follows : " There were certainly no ripe eggs in the abdo- 

 men, although there were a great many eggs in an immature condition." I 

 stated in the above mentioned paper, that the existence of the species 

 Ursula did not depend on these late, or September butterflies ; and the 

 reason is, that the female coming so late, and with immature eggs, the 

 season would either not allow the eggs to ripen, or if it did, and they were 

 impregnated, which would be doubtful, it would not allow the larvae to 

 hatch and to reach the hibernating stage. There is not time for all this 

 before frosts or cold weather. Of course, the same would hold good of 

 Arthemis, if possibly any females of a second brood should emerge. 



ON TWO GENERA OF PHYCID^:. 



BY A. R. GROTE. 



I find that unless we use neurational characters to separate the genera 

 of Phycidce, that it will be impossible to classify the species with accuracy. 

 All characters drawn from the periphery, the appendages of the body, will
