purplish-gray color is very characteristic of our whole series of about 20 speci- 

 mens. 



13. EuxoA QUADRiDENTATA G. & R. Truckee, Calif. (July 1-7). 9. 

 See remarks under fig. 6. 



14. EuxoA NiVEiLiNEA Grt. Redington, Ariz. 5 . 



16. 



[ EuxoA ORBICULARIS Sm., Pyramid Lake, Nevada. 5 and $ . 



Compare with fig. 



17. EuxoA TRiSTicuLA Morr.? Esmeralda Co., Nev. 9. 



We have a number of specimens, all from western localities, (Yellow- 

 stone Pk., Washington, etc.) which approach very close to the description and 

 to Hampson's figure of this species. The type locality of trislicula being Maine 

 we have, however, grave doubts as to the specific identity of the two forms. 



18. EuxoA TERRiTORiALis Sm. Eureka, Ut. 9 . 



This name will probably lit the species figured as well as any other 

 of the mcssoria group. It agrees well with a 9 co-type in our possession from 

 Glenwood Springs. 



19. EuxoA MALis Sm. Cartwright, Man. $ . 

 See remarks under fig. 12. 



20. EuxoA QUADRIDENTATA G. & R. Ft. Wingatc, N. M. (Oct. 1-7). 9. 



21. EuxoA sp. Eureka, Ut. 9 . 



Belongs in the lutulcnla Group, but we would hesitate to determine it as 

 this species if Hampson's figure is at all correct. We possess quite a series 

 from Utah which all agree fairly well in being a dull pinkish gray and having 

 all markings, with the exception of the dark median shade, indistinct.
