impressed in the middle; legs not so strongly spinose as in female;

 ventral plate broad, rather shallow, arcuate; lobes short, triangular.

Fedor, Lee County, Texas. Females and males collected in May 

 and June by Rev. G. Birkmann. 



Type.— Cat. No. 13758, U.S.N.M. 



This insect belongs near punctifrons Fox. It may be known from 

 punctifrons by the presence of two teeth on the clypeus and the 

 absence of "dense sericeous pile." The wings are as dark as some 

 specimens of sethiops Cress. The male is separated from the male 

 of punctifrons by the greater space between the eyes at the top; in 

 punctifrons it is about equal to the antennal joints three and four; 

 in fedor ensis it is greater than joints three and four. The male is 

 separated from intermedins Viereck by the denser punctured meso- 

 notum, etc. 



TACHYSPHEX BRUESI, new species. 



Separated from tenuipunctus Fox, its nearest ally, by the sculpture 

 of the propodeum and black abdomen. 



Female. — Length 8 mm. Clypeus broadly rounded apically with 

 two small lateral teeth, its surface and the front coarsely granular; 

 vertex and interocellar area closely punctured, neither distinctly 

 parted; depression of the vertex shallow, poorly defined; the space 

 between the eyes at the vertex greater than the length of the second 

 and third antennal joints, but less than the third and fourth; the 

 third and fourth antennal joints subequal; mesonotum with large 

 separate punctures, those on the sides closer; scutellum with well 

 separated punctures, not impressed; propodeum subtruncate and 

 transversely striate posteriorly, dorsally finely reticulate, laterally 

 striato-reticulate; third cubital cell longer on the radius than the sec- 

 ond; legs not strongly spined, inner calcarium not as long as the hind 

 basitarsis; apical margins of the dorsal abdominal segments nar- 

 rowly depressed; pygidium well defined, two and a half times as long 

 as broad; sparsely punctured, the apex narrowly truncate. Black; 

 tarsi and tegulse somewhat brownish; wings dusky-hyaline, iridescent; 

 venation brown.
