THE CANADIAN ENTOMOLOGIST. 65 



types of his N. A. Tortricids. At the time, I did not feel satisfied that 

 Sericoris argyrcelana Zell., was distinct from S. coruscana Clem., but 

 allowed both names to remain. After Prof Zeller's death, his collection 

 passed into the hands of Lord Walsingham, and I wrote to him about the 

 matter. He made an examination and wrote me that they were identical, 

 and that Prof Zeller had evidently reached that conclusion, for he had 

 placed them together in his collection. 



I have recently examined a large number of examples of the European 

 and American PJwxoptcris comptana Frol., and compared them critically 

 with Phoxopteris fragarice Walsh & Riley, and I am convinced that 

 they are the same thing. They are structurally identical, and my 

 European specimens shade off into cinnamon-colored forms, so that I can 

 find no line of distinction between them. The insect must, therefore, be 

 known hereafter as Phoxopteris comptana Frol.

* Pupal Term of Arctia nais. 



*^ found June i6, 1S75, laying eggs in a depression in ground recently 

 dug. Total number of eggs obtained about 500, i6th to 19th of June. 



Larvse began to appear June 24th. They were fed chiefly on Poly- 

 gonum acre, and one or two species nearest allied to acre, partly on Poly- 

 gonum aviculare, var. erectum, and partly on red clover. 



Pupation began July 23rd, and continued daily to August 8th, inclusive ; 

 a few more pupae formed to the i6th inclusive, when pupation practically 

 ceased. Only 5 pupations occurred later; two about 20th of August, one 

 about I St of October, and two in the last ten days of October. 



After losses from larval mortality and escapes, there remained August 

 1 6th nearly 200 larvae, almost mature. These shortly made final moult 

 and early in September almost ceased feeding. The hybernating dispo- 

 sition took possession of them, and out of nearly 200 mature larvae 

 remaining Sept. ist., not more than three formed pupa before winter. 



* Gladly giving some attention again to entomology, after several years neglect, I 

 find a few of my former notes, which, as far as they extend, were carefully made, and 

 may be of some use in supplementing other records, or for comparison of localities.
