notum yellow, mesonotum dark brown, legs yellow with brown femora; 

 abdomen yellow with fuscous markings. Tegmen fuscous yellow, 

 darkest toward apex of clavus. 



Pygophor but little deeper than wide, anal segment sunk well 

 into pygophor, spines on anal segment large, simple, inwardly turned 

 and diverging; styles very much like those of artemisiae but nar- 

 rower at apex and not so twisted; the aedeagus different. 



Length 2.5 mm. ; tegmen 1.8 mm. 

 Hab. Kaala Monntains, Oalni. (Swezey, September.) 

 In this species we have the aedeagus flattened laterally, 

 a condition found in the following four species.

 II, (6) p. 583. 



This is described by Kirkaldy as being a very variable species, 

 but in the long series I have examined this is not very evident. In 

 the male the dark band across the tegmen is narrow on the hind 

 margin and broad on the anterior margin, the costa being yellow; 

 this leaves a subquadrate yellow mark over the basal portion of the 

 clavus when tegmina are at rest; the female almost immaculate or 

 with a fuscous spot near end of clavus on hind margin. The spines 

 on the anal segment strong, wide apart, curved inward; the aedeagus 

 differs from that of artemisiae, but the genital styles are difficult to 

 separate.

 Soc, II, (3) p. 118. 



The male of this species can be recognized from dubaidiae 

 by the dark marking on the tegmina extending to the apex 

 and the subquadrate light mark at apex of clavus not notice- 

 able. The spines on the anal segment are near together and 

 the aedeagus recognizable. One male specimen from Kaala 

 Mountains has the tegmina uniformly dark fuscous brown.
