be distinguished from the Arizona race. We imagine that Bethune- 

 Baker's series from Ft. Wingate, N. M., which he refers to comyntas 

 (1. c. p. 101) is the same as our Arizona form. 



The species described by Wright from a single 2 as sissona 

 (Butt. W. Coast, p. 232, PI. 30, Fig. 400) is apparently, to judge by 

 the figure, a worn $ specimen of this species ; the wings are decidedly 

 rubbed so it is probable the tail has been torn off. Dr. McDunnough 

 took a small series of this species during the first week of July at 

 Shasta Retreat in the summer of 1915, the $ agreeing excellently 

 with Wright's figure ; the $ 's show little or no orange at angle of 

 hind wings above but the clearness of the under side maculation and 

 the small size would seem to point to comyntas; he also took a single 

 fairly typical amyntula in the same locality in the last week of June. 



Plebeius scudderi Edw. 



The name has been applied generally to the form of the Eastern 

 States, but the type locality given is Lake Winnipeg; the Edwards' 

 Collection contains only N. Y. specimens under scudderi and we could 

 find nothing in the Scudder Collection at Cambridge from the type 

 locality. The type form according to both the original description 

 and Edwards' later statement (Tr. Am. Ent. Soc. IV, 348) has no 

 red submarginal lunules on the under side of primaries and to judge 

 by a few Nepigon specimens before us which seem to be typical is 

 paler and rather rougher looking on the under side with more green- 

 ish scaling at base of wings ; Toronto specimens are fairly typical but 

 our N. Y. and North Indiana series show considerable red and are 

 brighter and more heavily marked. The species extends far into the 

 north ; we have a series from Atlin, B. C, near the Alaskan border 

 with the $ 's largely suffused with a pale grey-blue, more so than in 

 aster Edw. ; this latter name will apply to Newfoundland specimens 

 which seem sufficiently distinct to warrant a racial name. Specimens 

 from high altitudes in Colorado (Silverton, 10,000 ft.) are intermed- 

 iate in the $ 's between scudderi and melissa, some being without the 

 red submarginal band on primaries above and considerably suffused 

 with blue and others almost as in typical melissa; the $ 's and the 

 under sides of both sexes are close to typical scudderi. 



Melissa, judging by the presumable types from Colorado in Pitts- 

 burgh, apart from its heavy red submarginal markings on the under- 

 side, appears to vary from what we call typical scudderi in having the 

 discal row of black spots on the underside distinctly closer to the red
