CLEAR-WING MOTHS OF FAMILY AEGERIIDAE 71 



Distribution. — Arizona (Baboquivari and Santa Catalina Mountains). 



Type. — Male. In the United States National Aiuseuni. The allotype 

 female and two male and five female paratypes are also in the United States 

 National Museum. 



Remarks. — The food plant of this beautiful species is not known. How- 

 ever, the insect appears so well aligned with the group of species that bore 

 in the roots of herbaceous plants that its habits should prove similar ; it is 

 rather likely a root borer in one of the Composilae so abundantly repre- 

 sented in the Midwest. With one exception, a male from Sabino Canyon, 

 Santa Catalina Mountains, August 13, 1924 (E. P. Van Duzee), all the 

 known examples have been collected in the Baboquivari Mountains, Pima 

 County, August 15-30, 1923, by O. C. Poling, an experienced collector, 

 who vouches for the identity of the dimorphic sexes.

Examination of the type of infirma, American Museum of Natural His- 

 tory, shows it to be a worn female, not a male, of corni collected on Long 

 Island, N. Y., by S. L. Elliot. Additional bibliographical citations have 

 been placed under Conopia acerrubri, as they involve confusion with that 

 species.

 orange, third joint bla,ck above. Head tufted black and orange on top, 

 face white. Collar orange. Thorax bluish black, densely clothed laterally
