10. ToLYPE DisTiNCTA French. Eureka, Ut. $ . 



11. Malacosoma constricta Stretch. Eureka, Ut. $. 



This would seem to fit in with Stretch's description, but any determina- 

 tions in this group from single specimens are doubtful. 



12. Gluphisia sp. Provo, Ut. 9. 



A very interesting form, unlike anything wc have seen but probably 

 referable to either ridenda or wrightii. 



13. Raphia elbea Sm. Provo, Ut. 9 . 



One of the pale western forms, paler than the Colorado species, and 

 most nearly approaching elbca Sm. from N.. Mexico, although there are certain 

 slight differences which may be proved to be constant when breeding can be 

 done. 



14. Oncocnemis extranea Sm. Eureka, Ut. <J . 



Somewhat paler in ground-color than the typical Colorado form but 

 identical in markings. 



in 



Oligia (Hadenella) tonsa Grt. Eureka, Ut. 



Three forms of this very variable species. They agree with the co-types 

 of subjuncta Sm. in our possession. The shading of the median area is lacking 

 in fig. 15, prominent in fig. 17. 



18. Oligia tonsa ab. fasciata B. & McD. Eureka, Ut. $ Type. 



19. Oncocnemis chorda Grt. Eureka, Ut. $ . 



20. Oncocnemis regina Sm. Eureka, Ut. $ . 



Probably this species, although most of our Utah specimens are de- 

 cidedly suffused with pink on primaries. 



21. PsEUDANARTA SINGULA Grt. Eureka, Ut. 9 . 



Most easily recognizable by the prominent tooth of t. a. line on inner 

 margin and straight course of t. p. line from vein 4 to inner margin. 



22. Oncocnemis figurata Harv. Eureka, Ut. $ . 



Our Utah specimens are paler in ground color, but we can see no other 

 point of distinction. 



23. Oncocnemis lacticollis Sm. Eureka, Ut. S .
