eyes at the top about half as great as the distance at the bottom; sec- 

 ond antennal joint roundish, about one third the length of third, joints 

 three and four equal ; dorsulum shining, rather densely and finely 

 punctured, truncate anteriorly; scutellum not as densely punctured as 

 the dorsulum, metathorax dullish ; metanotum distinctly punctured, a 

 distinct longitudinal carina from middle of base extending to about 

 the middle; lateral and posterior faces distinctly striated; posterior 

 face with a shallow, circular fovea ; abdomen shining, densely cov- 

 ered with extremely fine punctures ; pygidium, narrow, obtusely pointed 

 at apex, somewhat excavated above. Color black; palpi pale brownish; 

 apical part of tegulae, a narrow band on apex, and extending along 

 side of each abdominal segment, apical joints of tarsi (more especi- 

 ally the posterior ones) reddish brown; face, pleura? and inner side of 

 tibiae with sparse sericeous pubescence. Wings dusky hyaline, nervures 

 dark brown. 



Habitat. Florissant, Colo., June 28, 1907 (S. A. Rohwer). 



Known from T. intermedius Vier. (Douglas Co., Ka.), its 

 nearest ally by its smaller size ; front without groove between 

 ocellus and insertion of antenna ; abdomen not, or but very 

 slightly, covered with silvery pubescence. 



In Fox's table in N. Am. Larridse it runs to 17 where it 

 runs out, falling between punctifrons and aethiops. It may 

 be known from both of these by its smaller size, and from 

 punctifrons by the absence of the dense sericeous pile, and 

 from aethiops by the much clearer wings. 



Tachysphex hitei n. sp. 



$. Length about &/ 2 mm. Clypeus truncate with a very minute 

 obtuse lateral tooth, densely punctured except on the extreme apical 

 margin which is shining; front densely, rather coarsely punctured; 

 vertex with finer punctures ; a somewhat indistinct line-like depres- 

 sion from lower ocellus to between antennae, and a broader and more 

 distinct one from ocellus to occiput; the depression behind lateral ocelli 

 distinct ; distance between eyes at the top about equal to the length 

 of antennal joints two plus three; second antennal joint about one- 

 third as long as third, dorsulum somewhat truncate at anterior mar- 

 gin, densely and finely punctured in general, but a spot on each anter- 

 ior part more coarsely punctured ; scutellum and postscutellum punc- 

 tured like the greater part of dorsulum; metathorax densely punctured 

 with medium size punctures, Ojii posterior face there is a distinct elon- 

 gate fovea ; abdomen distinctly, though finely punctured above and 

 beneath, ventral segments witli a few long reddish hairs; pygidium 

 distinctly margined, about twice as long as the width at base, apex
