line and a row of erect setae ; pronotal angles not impressed, 
side margins not distinctly bisinuate ; front of head without 
post clypeal convexity ; metasternum normally long ; ungual 
tooth antae-median in position, shorter than superior portion 
of claw; anterior clypeal margin shallowly sinute medially; 
sides of pronotum strongly, subangularly rounded at middle,

Head densely punctate, punctures separated by about one- 
fourth their own widths or coalescent, sparsely clothed with 
short golden pile ; clypeus densely punctate, punctures sepa- 
rated by about one-fourth their own widths or coalescent,

ture widely interrupted medially, margins strongly reflexed,

Holotype for Eagle Pass, Texas, March 30, 1908 returned 
to L. W. Saylor of the United States Biological Survey for de- 
position in the United States National Museum. One para- 
topotype in the writer’s collection. 
This species appears to be closely allied to Diplotaxis sul- 
catula Fall and D. beyeri Schaeffer. It can be separated from 
D. sulcatula by its angulate side clypeal margins, by its more
