PLATE I 



Fig. I. Olene PLAGiATA Wlk. ? Eureka, Ut. $. 



We have not enough Eastern material to determine whether this West- 

 ern form is specifically identical with the Eastern species. We possess a num- 

 ber of specimens from Glenwood Spgs., Colo., and Cartwright, Man., which 

 agree well with the specimen figured, and follow Dr. Dyar (Proc. Wash. Ent. 

 Sec, XIII, 17) in the nomenclature. 



2. Andropolia (Polia) acera Sm. Provo, Ut. $. 



This specimen has been compared with the type specimen. The type 

 locality is Pullman, Washington. 



3. Olene placiata Wlk.? Provo. Ut. 9. 



4. EuxoA cHOKis Harv. Eureka, Ut. 5 . 



A variable species, both as to size and maculation. Compare with figs. 

 7 and 17, both of which are, in our opinion, forms of the same species. The 

 ground color is a light brown, with often a slight tinge of reddish ; it is this 

 tinge which makes our fig. 4 appear darker than the other figures ; the irregular 

 black basal dash is quite characteristic. 



5. Tryphaena discoidalis Grt. Eureka, Ut. S ■ 



The figure appears too dark on account of the reddish shades in the 

 coloration of primaries. 



6. Euxoa idahoensis Grt. Eureka, Ut. 3. 



In the specimen figured the ground color is not so deep as was evi- 

 dently the case in Grote's specimens, the claviform is also obsolete, but we have 

 other specimens before us in which both claviform and t. p. line are quite dis- 

 inct. 



7. Euxoa choris Harv. Eureka, Ut. $ . 



A slightly smaller specimen than fig. 4, better marked in the terminal 

 area. 



8. Euxoa silens Grt. Eureka, Ut. 9 . 



A strongly marked specimen with large amount of gray suffusion. 



9. Lasiestra (Scotogramma) perplexa Sm. Stockton, Ut. 9. 

 Appears to fit in better with Smith's description of perplexa than with 



that of any allied species. The dark mark near apex on left side of photograph 

 is due to a rubbed spot. 



10. Euxoa oblongostigma Sm. Eureka, Ut. 9 . 



The orbicular in this specimen is less oblong than usual ; we can find, 

 however, no other points of distinction to typical oblongostigma. The red-brown 

 ground appears too dark in the photograph. 



11. Lycophotia RUDENS Harv. Eureka, Ut. $. 

 A typically marked specimen. 



12. Lycophotia nanalis Grt. (Syn. Caradrina mantalini Sm.) Eureka. 



Ut. $. 

 We think this is the true nanalis. We have the type of mantalini Sm. 

 and the tibiae are distinctly spinose, precluding association with Caradrina. It
