44 THE CANADIAN ENTOMOLOGIST. 



Am. species is 133. Mr. Meade has identified among them 27 European 

 species and Loew 7 more ; therefore 34 species seem to be identical with 

 European ones. The Museum owes the most sincere thanks to Mr. Meade 

 and to Baron v. Osten Sacken. 



Genus Hyetodesia Rond. (Aricia pt. Macq.) 



1. Bears a considerable resemblance to Aricia marmorata Zett. ; 8 



male and female ; Lake Super., Huds. Bay Terr., Can., N. Hampsh. 

 No specimen of A. 7narmorata is at hand. I consider A. 

 moj'ioides Ztti. (perhaps A. mori Zett. of O. Sack. Cat., p. 164) to be 

 identical with No. i. Loew's type is a female from Sitka 

 (Sahlberg), and an Aricia. 



2. Is perhaps a variety of No. i ; the longitudinal thoracic stripes are 



narrower ; 2, male and female ; Lake Super., N. Hampsh. 



3. Closely corresponds to the descriptions of A. serva ; this is perhaps 



also a var. of No. i; i, female \ Norway, Maine. 



4. Seems identical with A. lucoruin Fall. ; i, male ; West N. Y. 



5. Is very similar to A. obscurata Meig. ; i, male ; Huds. Bay Terr. 



6. Differs from any species I know; 4, male and female ; Brit. Amer., 



Western N. Y.; Geysers, Cala. 



This species is A. paiviceps, Loew collect., from Sitka, Sahlberg, 

 male, female; the male agrees perfectly with No. 6; the female 

 differs somewhat, but the 4 Spec, of No. 6 seem to represent 

 varieties. 



7. Bears a very close general resemblance to S. pagana Fabr., but 



differs by having the eyes decidedly pubescent and also by having 

 3 instead of 4 thoracic bristles behind the suture ; 2, male and 

 female; Englewood, N. Jers.; Maine. 



This species is identical with H. a?igelicce, Loew coll., male and 

 female ( Spilogaster angelicce. O. Sack. Catal., p. 165) and one Euro- 

 pean type sent by Loew as Fcllaca angeliac Scop. The differences 

 quoted above agree with F. angeliaz ; nevertheless the eyes are a 

 little less pubescent in the only European specimen before me, but 

 decidedly as pubescent in the 2 Amer. specimens in Loew's coll. 



There are in Loew's coll. the following species named, all differ- 

 ent from the No. 1-7 : A. schiiiophora, 3, male and female, from 

 Sitka, Sahlberg, and from Alaska, related to No. 5 but different. 

 A. consors, 2, male and female, from Sitka. Sahlberg, allied to No. 6.
