170 KANSAS UNIVERSITY SCIENCE BULLETIN. 



fully three-fourths of 4 and more than twice its apical diameter; inter- 

 ocular space a little more than joints 2 and 3; frons finely and very 

 closely punctate, but less so about the ocelli; vertex with rather large, 

 deep and separate punctures, postocellar depression deep; scutum well 

 depressed anteriorly mesad for at least one-half its length, a little polished 

 and compactly punctate; disc of propodeum granulate, the sides not very 

 distinctly punctate and striate, the posterior face distinctly striate, the 

 sulcus long and narrow; legs moderately spinose; venation not strong, 

 marginal cell moderately truncate, the second submarginal cell distinctly 

 longer than the third along the radius, the distance from the third to 

 the truncation much more than the length of the third along the radius; 

 abdomen shining; pygidium barely two times the length of its basal width, 

 its strongly margined sides nearly straight, very little constricted pre- 

 apically, very finely reticulate, and with sparse, well-distributed punc- 

 tures. Black; legs a little lighter colored apically; wings a little darkened 

 toward the tip; venation brown. Rather abundant silvery pile, with 

 which the abdomen is well fasciate. Length, 9 mm. (type). 



Phillips county, Kansas; Aug. 30, 1912. Three paratypes (one of 

 which is 10 mm. long) ; Barton and Russell counties. 



J . Anterior margin of clypeus subtruncate, somewhat produced in 

 the middle (more strongly so than in crass j/orm is ) , the lateral angles 

 sharp; antennae a little thickened mesad, joint 2 more than one-half of 

 3, which is a little shorter than 4; interocular space equal to joints 2-4, 

 or nearly; frons with very close, more or less confluent punctuies, those 

 of the vertex larger and separated from each other by their diameter or 

 more, vertex when viewed from behind a little depressed; thorax rather 

 coarsely and closely punctate, well depressed mesad for nearly the whole 

 length of the scutum; disc of propodeum somewhat coarsely granulate, 

 and with a few basal striae, the sides punctate-striate, posterior face 

 coarsely striate, the fovea broad; legs scarcely spinose, wings about as in 

 the Q , except that the second and third submarginal cells are subequal 

 along the radius; abdomen shining; pygidial area pilose, emargination 

 of eighth ventral segment broad. Colored as in the j . Pile moderate, 

 abdomen well silvery fasciate. Length, 7. .5 mm. 



Baiton county, Kansas; June, 1912. 



Related to apicalis. 



Tadujsphex glabrior n. sp. 

 (Fig. 65, clypeus, j; .) 

 2 . Moderately stout. Anterior margin of clypeus rather narrowly 

 subtruncate, a little produced mesad (as in crasaiformis) , in addition to 

 the lateral angles there are two distinct lateral teeth ; antennae a little 

 stouter than in sepitlcralis, joint 2 about one-half of 3, the latter is 

 hardly two times its own diameter at apex and two-thirds to three- 

 fourths the length of 4 ; interocular space about equal to antennal joints 

 3 and 4; frons finely punctate; vertex with the punctures more separate, 

 the sculpture being a little finer than in sepucralis; disc of propodeum 

 moderately grranulate, with poor indications of basal striae, the sides well 

 striate, the posterior face coarsely so, the almond-shaped fovea large; 

 legs moderately spinose; venation rather weak, marginal cell with the
