118. EUCOSMA EXPOUTANA, new species. 

 (Fig. 249.) 



In pattern like suadana Heinrich but with a more washed-out ap- 

 pearance, the white areas of fore wing more sordid and the fuscous 

 spots and markings paler and less sharply defined. The entire in- 

 sect has a rubbed over appearancfe as if the pattern had been partially 

 erased. The curved fuscous line from beyond outer third of costa 

 to tornus so prominent in suadana is either broken in exyoUtana or 

 else narrow and obscure. In genitalia it equals rorana Kearfott, 

 but differs in lacking a completed fascia on fore wing beyond middle, 

 the head is more whitish and the insect generally lacks the rusty 

 appearance of Kearfott's species. The last joint of the labial palpus 

 is black in both forms. 



Male genitalia of type figured. 



Alar expanse. — 16-20 mm. 



Type.— C^it. No. 24818 U.S.N.M. 



Paratypes. — In National Collection, American Museum, and col- 

 lection Barnes. 



Type locality. — Provo, Utah. 



Food plami,. — Unknown. 



Described from male type (" labeled, Provo, Utah, Tom Spalding, 

 VIII-11-8 ") and four male and two female paratypes from Provo, 

 Utah (Aug. 4 to 20), and two male and one female paratypes from 

 Eureka, Utah ("VII-8-11," "VII-2^11," " VIII-15-11"), all col- 

 lected by Tom Spalding. 



These paratypes have been selected from a large series in the 

 National Museum and Barnes's collections. There is also a specimen 

 of the same species in the National Collection from Arizona. 



This species may prove on rearing to be nothing but a variety of 

 rorana. The genitalia are the same in both. In large series of 

 expolitana^ however, there is so little variety in pattern that I do 

 not feel justified in lumping them with rorana. In general appear- 

 ance the two appear quite distinct.
