10, 11) ; occasional specimens lack the apical ocellus on underside of 

 primaries but normally this is well developed. 



C. ochracea Edw. 



The species was described from specimens from Lake Winnipeg, 

 California, and Kansas ; the common species from the Lake Winnipeg 

 region is inornata according to information received from Mr. Wallis 

 of Winnipeg but there is a 9 type of ochracea in the Edwards Coll. 

 labelled Winnipeg and we also have a 9 from Cartwright, Man., 

 which agrees with the description ; we do not know the species from 

 California. The main home of the species is the Rocky Mt. region 

 of Colorado, Utah and adjoining states; it may be generally recog- 

 nized by the white blotches at base of secondaries on underside and 

 by the usually well developed ocelli, especially noticeable in Utah 

 specimens (vide Skinner, 1. c. Fig. 14) ; inornata may prove to be a 

 dark form with reduced ocelli on secondaries ; we have specimens of 

 ochracea from Colo, which lack the basal blotches and merely differ 

 from inornata in the paler color. Brenda Edw. described from some 

 of Reakirt's material, ostensibly from Los Angeles, Calif., is a typical 

 ochracea as a study of the types in the Strecker Collection has shown 

 us ; the locality was very possibly erroneous as we know of no authen- 

 tic records for ochracea from this region; Wright's figures of brenda 

 should be referred to one of the summer forms of California. 



Cercvonis oetus Bdv. (PI. VIII, Figs. 5-7). 



We cannot, after a careful study of both types, separate charon 

 Edw. from this species ; it has a wide range over all the western high 

 mountain regions and extends far into the north, phocus Edw., de- 

 scribed from specimens taken at Lake Lahache, B. C, proving to be 

 a form of this species with dark, almost immaculate underside. Ed- 

 wards (Can. Ent. XII, 55) has referred oetus to silvestris on the 

 strength of a so-called 'type' received from Boisduval; the real type 

 however remained in the Boisduval collection and has recently been 

 figured by M. Oberthur (Et de Lep. Comp. IX (2) PI. 264, Figs. 

 2203/4). The specimen referred to by Edwards we have recently 

 seen in Pittsburgh and it proves a misidentification on Edwards' part ; 

 this specimen agrees with Oberthur's figure of oetus type but the re- 

 mainder of Edwards' series labelled oetus are pure and simple silves- 

 tris. The distinctness of the median band on the underside of the 

 hind wings is very variable but usually sufficient is present for one to
