On the species of TRYPOX V1.01V inliabitiiig 
America Xortli of Mexico. 
BY WILLIAM J. FOX. 
Through the kindness of Mr. E. T. Cresson, I have had the op- 
portunity of working over this interesting genus of Fossorial Hy- 
inenoptera. I do not offer any suggestion as to the proper position 
of this genus, which has been placed in the Larridse by most Euro- 
pean authors. Mr. Cresson has placed it in the Crabronidie, where 
I prefer to leave it for the present at least. Herein eight new species 
have been described, also two from Cuba and Mexico, res|)ectively, 
have been added to our fauna. The species are, as a rule, easily 
distinguished, presenting characters which are readily seen. The 
types of all the species herein described as new, with the exception 
of T. Johmotii (which is from my collection), and several of Pack- 
ard’s, will be found in the collection of the American Entomological 
Society. 
The species are distinguished as follows : 
Females. 
Metanotum not trisulcate. 
Abrloiiieii entirely black. 
Metanotum punctured. 
Wings blue-black; thorax clothed with black pile albilarse. 
Wings with the anterior pair only fuscous, the posterior ones hyaline, 
except apical margin; thorax witli pale pubescence. 
albipilo>«niu. 
Wings hyaline, their apical margin and the marginal cell fuscous; thorax 
and abdomen with silvery pile excavafiini. 
Metanotum with an enclosed space. 
Anterior portion of clypeus without a carina; wings, except apical margin, 
hyaline ; posterior tarsi, except base and ape.x, whitish. .olavaluill. 
Anterior portion of clypeus with a strong polished carina ; wings fuscous; 
posterior tarsi black project uiii. 
Metanotum without enclosed space. 
Metathorax sulcate its entire length, more deeply so posteriorly, the fur- 
row- somewhat interrupted at apex of metanotum. 
Clypeus with a hroad, quadrate, tooth medially (fig. 10) apicaliN.
