darkened; dorsal angle about right and excision rather deep; annulate portion 
shorter than basal portion. Clypeus and lower genae white, with white hair. 
Palpus creamy white; second segment slightly swollen basally, tapering to a 
blunt apex, with short black hair. 
Mesonotum olive brown, with erect black hair and recumbent whitish hair; 
prescutal lobe somewhat reddened. Pleura, sternum, and coxae gray, with white 
hair. Wing hyaline; cell R; slightly narrowed apically. Femora reddish, some-

Abdomen above brown, with a pronounced, creamy-white, median stripe on 
tergites 1-6 and a concolorous sublateral stripe joined to median stripe at 
anterior margin of first tergite and breaking into spots beyond second tergite; 
extreme lateral margin white, with white hair; venter pale reddish, with a 
gray median stripe, widening posteriorly. 
Male.—Kye distinctly pilose, areas of large and small facets rather distinctly 
differentiated and the former extensive; palpus stout, creamy white. Abdomen 
slightly more yellowish sublaterally than in female, the body coloration 
otherwise essentially the same. 
Type.—Male, originally in the Bellardi collection. 
Type locality—Mexico. 
Distribution—Texas to Guatemala. February (Guatemala) to 
May 5 (Uvalde, Tex.). In the United States National Museum, one 
female, five males, all from Texas. 
Krober (9, p. 248) described what he believed to be ¢rugudt Bellardi 
from Brazil, later placing it as a possible synonym of 7’abanus occi- 
dentalis Linnaeus. However, the species before him had bare eyes 
and a narrower frons, with the sides not parallel. This could not be 
Bellardi’s species.
