domen more conspicuously marked with chestnut-red ; segments 2, 3, 4, 

 and 6 broadly banded with yellow, segment 5 chestnut-red ; anal tuft, short, 

 rounded, yellow, and red, black at the sides. Wings are flushed more 

 brightly with yellow and red. Otherwise like the male. 



Expanse : Male 24 to 26 mm., female 28 to 30 mm. 



Distribution. — Colorado, New Mexico, Texas, Kansas. 



Type. — Male. In the United States National Museum. 



Remarks. — With the exception of one adequate series of both sexes, 

 collected by E. J. Oslar, of Denver, Colo., at Turkey Creek, Jefferson 

 County, Colo., 6,000 feet, August 2-6, 1923, only a few individual speci- 

 mens of this species have been collected. The type specimens are simply 

 labeled "Texas" ; other specimens examined are one male, Pecos, N. Mex., 

 July 22 (Cockerell) ; one male, Wilson County, Kans., 1916 (Beamer), 

 and one female, Graham County, Kans., 2,130 feet, August 16, 1912 (F. F. 

 Williams), in the University of Kansas collection. When its food plants 

 and habits are better known, solituda should prove to be conspecific with 

 emphytifonnis, the only other species in the genus. The only difference 

 between them appears to be in coloration, solituda being characteristically 

 light colored in its dry western environment and einphytijormis dark 

 colored in the humid climate of the South.
