134 BULLETIN 190, UNITED STATES NATIONAL MUSEUM 



Expanse : Male 14 to 16 mm., female 16 to 18 mm. 



Distrihution. — Kansas. Oklahoma, Texas. New Mexico. 



Type. — Female. In the United States National Museum. From Al- 

 buquerque, N. Mex. (Cockerell). 



Remarks. — Critical study confirms Beutenmiiller's conclusions that 

 this species must be placed in a genus by itself. It is unique among all 

 North American species. Field notes of F. H. Snow connect the insect 

 with the leguminous plant Hoffmannseggia Jakarta, on which he cap- 

 tured numbers of the moths, Cimarron River, Clark County, Kans., 1,962 

 feet, June, but rearing was not attempted. Otherwise, only scattered 

 records of the species are available. The type comes from Albuquerque, 

 N. Mex. (Cockerell). Specimens other than the type are one male, Lucy, 

 N. Mex., July 18, 1932 (C. W. Sabrosky) ; and one male, Marfa, Tex., 

 June 5, 1908 (Mitchell and Cushman).
