114 THE CANADIAN ENTOMOLOGIST. 



Further examples collected at Rosthern, also by Mr. Willing, changed 

 to pupaj on June 17, producing the imagoes on July 15. These larvae 

 Mr. Willing says were very plentiful on Thermopsis rhombifolia, Nutt. 

 Five specimens which liad been killed by a fungus, and which were still 

 attached to the plants, were received at Ottawa, and afterwards one pupa, 

 with cast skin attached, and two of the bred moths were sent for examina- 

 tion. All the tubercles in these six specimens are distinctly reddish, and 

 the bristles conspicuously red, of about the same colour as those of Isia 

 Isabella. S. & A. The five dead larv?e all show the dorsal stripe. 



Larvfe which the writer received from Toronto hibernated in the 

 penultimate stage. .Specimens which Mr. D. Brainerd collected at Mont- 

 real moulted twice in the spring, as did also four larvae found at Ottawa in 

 early April, by Mr. C. H. Young. From data at hand it would appear 

 that there is only one brood in the year. It would be interesting to rear 

 a large number of the larvae from the egg, and note all rlie differences.

Virgo, var. citrinaria. — Mr. J. A. Moffat tells me that he has bred 

 two specimens of this variety, which differs in having yellow secondaries, 

 from a batch of larvae found at the same time at Hamilton, Ont. 



2. ViRGUNCULA has a wide range of distribution. In Ontario it is a 

 common species in certain districts, but very rare in others. At Toronto 

 during some seasons I have found the moths exceedingly abundant. The 

 life-history of this Arctian was published by the writer in the Canadian
