angle which at times shows ruddy tints ; we have before us 3 $ 's from 

 Salida, Colo. (July 1-7), 1 $ labelled Colorado and 1 S taken in 

 Southern Utah by Dr. Barnes; for this race we propose the name 

 centralis, making the above mentioned specimens types and figuring 

 them on PI. XVI, Figs. 7, 8. 



Turning to P. enoptes Bdv. we now offer a figure of the $ geni- 

 talia (PI. XVII, Fig. 1) which shows at a glance the wide difference 

 which exists between it and P. battoides. The tegumen is of essentially 

 the same general type but the Valvae are much closer to the Glau- 

 copsyche type than we find in battoides, possessing none of the com- 

 plicated armature found in this species ; they are broad, flat and simple, 

 curving upward distally, the broad distal margin being furnished with 

 a row of small teeth ending ventrally in a single strong spine below 

 which is a rather deep excavation. The types of enoptes have been 

 figured by M. Oberthur (Etudes de Lep. Comp. IX, Pt. 1 PI. 237, Figs. 

 1948/9) ; we have specimens exactly matching these types from 

 Truckee, Calif. ; our series from Mineral King, Calif., specimens of 

 which are figured in our Contributions Vol. Ill, PI. XI, Figs. 1 and 4, 

 differ in their slightly paler ground color on underside but are other- 

 wise identical. 



A further study of the genitalia (PI. XVII, Fig. 2) of glaucon 

 Edw., which we have already discussed and figured in the above men- 

 tioned paper, convinces us that this is merely a racial form of enoptes 

 with rather heavier orange band on underside of secondaries and ten- 

 dency to slight orange shading at outer angle of primaries. 



Our species P. rita from Arizona we have already figured and 

 now give figures of the genitalia (PI. XVII, Figs. 5, 7) showing the 

 close relationship to glaucon from which it differs among other details 

 in the much greater length of the terminal spine on the claspers. 



We have discovered an undescribed species, apparently confined 

 to certain mountainous districts of Utah, which has probably gone 

 under the name of glaucon but which, if our conception of this form 

 be correct, is specifically distinct. The upper side of the $ is very 

 similar to that of glaucon but there is prominent orange shading at 

 anal angle of secondaries above the dark border; the under side is 

 paler with the black spots of secondaries much smaller in size; on the 

 primaries there is a broad submarginal orange band narrowing towards 

 apex of wing and not quite attaining costa, this is bordered inwardly 

 by narrow dark streaks ; on the secondaries there is a subterminal row
