NO. 3660 MICROLEPIDOPTERA, XVII—CLARKE 53 
very small, from dorsal, median surface of ductus bursae. 
Holotype: U.S. National Museum No. 69741. 
Type-locality: Mexico, Tehuacan. 
Distribution: Mexico. 
Described from the female holotype (October 10) and three 99 
paratypes all from the same locality (September 12). 
I have placed hemitephras in Lasiothyris on the basis of the asym- 
metrical and much involved genitalia. Males are not known but 
probably, when discovered, will approach diamphidia in the form of 
the genitalia. 
There are no species that are similar to hemitephras in coloring 
or maculation. Superficially, the forewing of hemitephras appears 
pale gray in the basal three-fifths and ochraceous buff in the apical 
two-fifths.

creamy white with ocherous suffusion laterally. Thorax ochraceous 
buff with dull fuscous suffusion; tegula paler posteriorly. Forewing

gray scales, and between the basal two, touching cell, a fuscous spot; 
costa mostly leaden gray with short, transverse fasciae of this color 
at one-sixth, one-third, midcosta, and at apical third, the last con- 
tinued outwardly and obliquely as a line to vein 4, then inwardly, 
obliquely, to tornus; several groups of leaden-gray scales between 
this fascia and apex; outer third of wing, between the lead-colored 
lines and spots, fuscous, mixed with tawny; on middle of costa a 
fuscous patch edged inwardly with tawny; underside fuscous, with a 
few whitish spots on outer half of costa; cilia alternating groups of 
buff and leaden-gray scales. Hindwing fuscous; paler basally; cilia 
light gray with a broad grayish-fuscous subbasal line. Foreleg creamy 
white; femur and tibia heavily overlaid with fuscous on outer side; 
tarsal segments broadly banded with fuscous; midleg similar to fore- 
leg; hindleg ocherous white; tibia suffused fuscous dorsally; tarsus
