218 ENTOMOLOGICAL NEWS. [November, 



frozen over solid in all but well-protected parts. Mr. L. Kohl 

 went with me, a staunch collector 'midst snow squalls, of which 

 we had several and equally tireless when surrounded by clouds 

 of mosquitoes. We found sixty larvae, of which we unconsciously 

 slaughtered about eighteen in the following manner. The spot 

 selected is very miry and surrounded by shrubbery, but inacces- 

 sible, except on coldest days of year. There we struck a bonanza. 

 We did not find many larvae above frost line, and I suggested to 

 my friend, who carried a mechanic's jack-knife, to cut reeds as 

 far as possible below frozen parts. By so doing we found many 

 more, but mutilated about every third larva discovered. There 

 was from three to five inches of frozen muck, through which we 

 could not cut, and in this layer of frigid soil found two-thirds of 

 all specimens. The stems were frozen solid below water-line and 

 a thin coating of ice surrounded the Winter quarters of the larvae. 

 The interstitial part of stalks below frost line surrounding galleries 

 was filled with icy particles and hard to cut. I found repeatedly 

 both larva? and empty pupa-cases in one and the same stem, thus 

 verifying Dr. Kellicott's statement that A. obliquata is double- 

 brooded. 



At the end of the first week in May, some of these larvae trans- 

 formed into pupae; others had turned black in color previous to 

 such transformation. I kept each larva in a section of the Typha 

 stem, placed into a jar containing damp moss. A few that ven- 

 tured out of their Winter quarters and buried in the moss, died 

 during a cold snap subsequently. Of others I had on previous 

 occasions collected later in April, after cessation of heavy frosts, 

 none died with me, although the larvae were removed from the 

 stems when found and placed into damp moss until the last two 

 transformations were completed.

Argynnis astarte Doub.-Hew. ("Genera Diurnal Lepidoptera," 

 t. 23, fig. 5), which has only been known, since its discovery in 

 1848, by one of Lord Derby's collectors in British Columbia, by 

 the type in the British Museum, and the figure above cited, has 

 recently been rediscovered by Mr. Thomas E. Bean, who took
