290 MALE GENITALIA OF NORTH AMERICAN HESPERIIDAE 



the Rio Grande to the north and south, and thence to and up 

 the Cahfornian coast. 



The genitaha of occidentalis are the same as those of tessellata 

 except that the valve lacks the toothed projection. 



Records: Texas, Ysleta, El Paso, Corpus Christi, Round 

 Mountain; Arizona, Tucson; New Mexico, Highrolls, Alamo- 

 gordo; California, La Jolla, November (Williams), Dobel. 



9. Heliopetes domicella Erichson (Fig. 9.) 



This species has the costal fold and tibial tuft. 



The tegumen is provided with a long uncus, ending in a large 

 truncate projection densely covered with hairs projecting back- 

 wards; the scaphium is shagreened at its apex; the valve is 

 split at its terminus, the dorsal lobe rounded and the ventral 

 lobe larger, convolute, and serrate on the caudal margin; the 

 aedoeagus is simple. 



The tegumen is quite unlike that of any of the species of 

 Hesperia or any other species of Heliopetes that we have ex- 

 amined. 



Records: Arizona, Tucson; Mexico, Cohma; Argentine 

 Republic, La Rioja. 



10. Heliopetes ericetorum Boisdiivul (Fig. 10.) 



This species has the costal fold and tibial tuft. 



The type has been admirably figured by 01)ertliiir^'' and 

 Lindsey has figured both sexes.^® 



The uncus ends in split slender beaked processes; the scaphi- 

 um is present and in addition the girdle of the tegumen is ex- 

 panded outwardly on each side, bearing below the scaphium 

 substantial projecting arms dentate at their outer ends. The 

 valve is split at the terminus, the ventral portion hooked and 

 with small teeth at the end; the aedoeagus is simple.
