PLATE III 



Fig. I. ApANTKSis BLAKEi Gft. ? Eiireka, Ut. S. 



We think this is probably the true blakci; Grote's description gives sec- 

 ondaries as "deep yellow with a dnil red tinge ;" the secondaries of our speci- 

 men are vermillion tinged slightly with yellowish at anal angle. The species ' 

 which goes under the name of blakci and of which nevadensis has been made a 

 variety by Hampson, has the secondaries pale whitish to rose-color, agreeing 

 fully with nevadensis in this respect ; in long series from Glenwood Spgs., 

 Colo., of both forms we have failed to tind any with color of secondaries ap- 

 roaching red or yellowish-red; it appears to us that the name holanderi Stretch 

 would apply much better to this form with paler secondaries, as Stretch men- 

 tions the fact that they are rose-colored in his types ; these are, however, con- 

 siderably smaller, to judge by the illustration, and are from California. An- 

 other fact that would tend to separate these forms is that our Utah specimens 

 have all been taken in early spring (April-May) and we have Colorado species 

 that seem to agree fairly closely with these taken also in early spring (June 1-7) ; 

 the form with pinkish secondaries on the other hand occurs tirst in mid-summer 

 and continues until fall ; our dates range from July 8-15 to October 1-7, the 

 form we have called holanderi being apparently most common in August, whilst 

 nevadensis appears in numbers in late September. If Hampson's figure of 

 favorita Neum. is at all correct, it is probably that this species is also closely 

 related to blakei; it certainly has nothing to do with phyllira as listed by Dyar. 



2. ApANTESis TOOELE var. opHiR B. & McD. Eureka, Ut. $ . 



Agrees with type ; easily separated from tooele by its unicolorous black 

 thorax. 



3. Apantesis TOOELE B. & McD. Stockton, Ut. $ . 



We think this is referable to our species. The secondaries are bright 

 red. 



4. Hyperaeschra sthagula var. ochreata B. & McD. Provo, Ut. S Type. 



5. Schizura ipomoeae Doub. Provo, Ut. $. 



A rather pale western form ; ground color a pale red-brown with con- 

 siderable greyish suffusion around discal dash and at apex. 



6. Jana.ssa coloradensls H. Edw. Provo, Ut. 9 . 



This species, listed by Packard as a synonym of perangulala Edw. may 

 be distinguished by the presence of a small scale tooth on inner margin of pri- 

 maries, most prominent in $ and hardly seen in the photograph. In perangu- 

 lala the inner margin is also somewhat ochreous. The 9 9 of the two species 

 are very difficult to separate when rubbed. 



7. Janassa coloradensis H. Edw. Provo, Ut. 9 . 



A still paler form than the preceding with maculation almost obsolete. 



8. Apantesis blakei Grt. Eureka, Ut. 9 . 

 Without doubt the 9 of our fig. i. 



g. Apantesis tooele var. ophir B. & McD. Eureka, Ut. 9. 

 An interesting form with immaculate scarlet secondaries.
