without being able to discover any feature that could be used to separate the 

 forms of one locality from those of another. It will need careful study to 

 decide such problems and for the present we have placed the species figured 

 under laudabilis Gn. 



11. Hvssi.\ (Uloloxche) orbiculata Sm. Eureka, Ut. 9. 



More prominently marked with white below reniform than in most 

 specimens. 



12. AcRONYCTA MORULA G. & R. Decatur, 111. S . 



A rather undersized specimen but typical in its markings. 



13. AcRONVCTA viNNLLA Grt. Decatur. 111. 9. 



14. CvMATopHORA pusTULARiA Hbn. Decatur, 111. S . 



15. Trvphaena (Rhynchagrotis) binominalis Sm. Eureka, Ut. S- 

 The specimen agrees well with Smith's description of binominalis. We 



have an idea that it and crcnulata Sm. are but forms of one variable species ; 

 the yellow costal border does not seem specific in character, judging by a long 

 series before us, which shows all manner of intergrades. 



16. EuxoA ALBALis Grt. Provo, Utah. 9 • 



This is the true albalis, a pale grayish form with rather diffuse mark- 

 ings, the terminal area of the same gray coloring as the remainder of the wing; 

 the species varies considerably in the distinctness of the maculation ; at times 

 the t. p. line is distinct : it is mostly, however, not visible ; in one 9 before us 

 the whole area to subterminal line is completely washed with whitish, leaving 

 only the black basal dash and the white orbicular ; this latter is the most prom- 

 inent feature of the maculation, whereas in cloantlioides Grt. it is rather the 

 white mark at the base of the reniform which strikes the eye at a casual glance. 

 We have this species from Utah and Nevada — very fresh and perfect examples 

 from the former locality. 



17. Oncocnf.mis MAJOR Grt. Eureka, Utah. 9 . 



The photograph shows a very fresh and strongly marked specimen ; 

 the claviform and orbicular are both fairly distinct. 



18. PoLiA (Mamestra) detracta Wlk. Decatur, 111. $. 



19. Chytonix palliatricula Gn. Decatur, ill. $. 



This is the form ias/'is Gn. with median area not suffused with white. 



20. Eu.\o.\ NOSTRA Sm.? Eureka, Ut. $ 



The specimen is considerably paler in the median and subterminal areas 

 than one we have belonging to the type lot. but we believe the species shows 

 considerable variation in this direction. 



21. Sicya truncataria Gn. Eureka, Ut. S . 



The contrasting yellow and red-brown shades are almost lost in the 

 photograph.
