p. 170 of his article; it agrees in size, width of dark border, and the 

 fact that the dark sufifusion on secondaries extends over a considerable 

 portion of the wing. Henry Edwards, basing his knowledge of occi- 

 dentalis Scud, on the types in the W. H. Edwards' Collection from 

 Mackenzie River, {vide Pac. Coast Lep. p. 125) considered chrys- 

 ontelas a distinct species; just what species these Edwards' specimens 

 represent it is hard to say and we have no further note on the speci- 

 mens except that they exist at Pittsburg in the Carnegie Museum; if 

 however Edwards' figures of occidentalis (Butt. N. Am. I. Colias, VII, 

 figs. 1-4) are drawn up from these types then they certainly, as Hagen 

 says (1. c. p. 165) represent something quite different from the S 

 type in Cambridge and do not agree well with Scudder's original 

 description, notably in the small amount of black suffusion on sec- 

 ondaries of $ ; Scudder distinctly states that "grayish scales are 

 scattered over nearly the whole wing, more profuse at base" ; the 

 interior margin of the black terminal band also does not coincide 

 with Scudder's figure (1. c. p. 107) nor is the color of the underside 

 of secondaries deep enough yellow ; judging from the mere figures 

 we should suggest that Edwards' $ occidentalis comes very close 

 to some Calgary specimens of interior before us whilst his 9 is prob- 

 ably referable to a yellow form of Christina Edw. In view of the dis- 

 crepancies which exist between Edwards' figures of occidentalis (pre- 

 sumably based on his knowledge of the species from his Mackenzie 

 river types) and the original description we believe we are justified 

 in restricting the type of this species to the $ specimen in Cambridge 

 from Port Townsend, Gulf of Georgia (Agassiz) which fully agrees 

 with Scudder's diagnosis ; the exact relationship between occidentalis 

 and chrysoniclas will have to be left for discussion until such a time 

 as good series of occidentalis in both sexes are available from Port 

 Townsend ; we might note that the Vancouver Is. form which we have 

 been inclined to associate with this name (1916, Contr. Ill, (2) pp. 67, 

 68) is slightly smaller than Scudder's type but otherwise close in gen- 

 eral maculation and habitus. 



EURYMUS INTERIOR Scud. 



Dr. Hagen has already given full details regarding the types of 

 this species (1. c. p. 159) ; the type at Cambridge is labelled "Rapids 

 of Saskatchewan" and other specimens bear the label "Portage." The
