the type which is in Cambridge ; the forms possibly show intergrades 

 but may, to judge from the material before us, represent high and low 

 altitude forms of one race, typical Colorado apparently not being found 

 much below 9000 feet. 



Manitoba Scud, was described from specimens from Colo. 

 (Mead) ; Pike's Peak, Colo. (Edwards) ; Lake Winnipeg (Scudder 

 and Kennicott) ; Lahache, No. B. C. (Crotch) and Riviere de Loup, 

 Que. (Couper) ; both the $ 's figured, as well as the one serving for 

 the drawing of the genitalia, are from Lahache, B. C. so we see noth- 

 ing for it but to make this the type locality in spite of the name which 

 is unfortunately chosen; Fig. 11 will be that of the type, which we 

 have found and labelled in the Scudder Collection at Cambridge. We 

 cannot separate laiirentina Lym. from this form; both show the same 

 dark brownish-green underside in the $ 's and we believe that both 

 names apply to a race extending over the entire northern portion of the 

 continent ; the 9 's are considerably greener beneath than the $ 's. 



Idaho Edw., described from Oregon, Washington, and California 

 is a form with paler, yellowish green underside of secondaries, on 

 which the white markings stand out very distinctly ; we would restrict 

 the type to the $ from East Calif, in the Edwards' Collection. 



Assiniboia Lyman is a closely related form, but the spots on the 

 underside of secondaries are suffused with the yellow ground color and 

 rendered quite indistinct ; they are also smaller. 



Oregonia Edw. we would restrict to the four specimens (2 $ 2 ) 

 from N. Calif, in the Edwards' Collection ; they have a distinct pur- 

 plish tinge to the ground color on the underside of hind wings with 

 rather indistinct spots ; we have not seen anything just like them. 



After an examination of the types of c obelus Edw. and harpalns 

 Edw. in Pittsburgh we should not be surprised if both these so-called 

 species prove to be forms of comma; harpalus approaches close to 

 assiniboia Lym. whilst cabelus appears, to be a form in which the spots 

 on the underside of secondaries are reduced to mere points ; we only 

 offer this as a suggestion at present as we have no material from the 

 type locality (Nevada) which matches these types. 



Manitoboidcs Fletch has been separated from comma by Dr. 

 Dyar ; we have one of the 9 Cotypes, a very poor specimen, before us 

 and think this action is correct. The species seems close to metea of 

 which it may possibly prove to be a race, yellower in maculation than 

 the typical one. The larvae of both these species, in contradistinction to
