Tachysphex texanus (Cress.) 

 (Fig. 47, tip of wing.) 

 Larrada texana Cresson; Trans. Am. Ent. Soc, IV, 214; 1872. ^ j .

o . Stout, nearly as large as tarsatus, which it resembles superficially. 

 Anterior margin of clypeus subtruncate, without teeth, the lateral angles 

 sharp, rim rather wide; clypeus quite convex and with a few large punc- 

 tures on its anterior half; joint 2 of antennae about one-half of 3, which 

 is a little shorter than 4; the interocular space about equal to joints 2 and 

 3, perhaps a little greater; frons finely and quite closely punctate basally, 

 the punctures larger higher up; vertex shining, with rather large and deep 

 separate punctures; disc of propodeum rather coarsely granulate, the sides 

 striate, the posterior face more coarsely so, its fovea large and shining, 

 wedge-shaped; legs moderately spinose; venation rather delicate, mar- 

 ginal cell obliquely subti-uncate, the second submarginal cell usually a 

 good deal wider than the third along the radius ; abdomen finely reticulate ; 

 pygidium about two times as long as the basal width, well margined, a 

 little constricted preapically, the whole finely reticulate and with sparse, 

 irregularly disposed punctures. Black; legs brownish red apically; wings 

 clear; abdomen all red. Moderately pilose. Length, 7. .5-10 mm. 



^ . Stout. Clypeus subtruncate, a little produced mesad; punctures 

 coarser in this sex; interocular space a little more than the length of 

 antennal joints 3 and 4; eighth ventral segment of abdomen broadly 

 emarginate, and with no median tooth. Colored as in j . Length, 

 6.5-7 mm. 



A good series of o o from western Kansas; two ^ ^ from Stevens 

 and Norton counties seem to belong here. 



Tachysphex sculptiloides n. sp. 

 o . stout, somewhat like a small te.vaims. Anterior margin of clypeus 

 subtruncate, not emarginate mesad, a distinct lateral tooth; clypeal rim 

 broad and with large punctures at its base, apical half (with the excep- 

 tion just mentioned) smooth and shining; antennae moderately slender, 

 joint 2 one-half as long as 3, which is a little shorter than 4; interocular 

 space nearly as vidde as is the length of antennal joints 2 and 3; frons 

 with moderately fine, shallow and well separated punctures, the interspace 

 finely reticulate; vertex shining, with medium-sized, deep punctures; 

 ocellar depression deep; dorsum of thorax shining, with large, rather 

 close punctures; disc of propodeum rather coarsely granulate, and with 

 ii-regular, more or less longitudinal and parallel, well separated lines (not 

 so evident in the two cotypes), giving the disc an imperfectly striate 

 effect; sides rather coarsely and strongly striate; a carina separates the 

 disc from the posterior face, which is coarsely striate and with a large, 

 deep wedge-shaped fovea; legs moderately spinose; marginal cell rather 

 narrowly and not very obliquely truncate; abdomen shining; pygidium 

 about two and one-fourth times as long as its basal width, scarce con- 

 stricted preapically, smooth and very sparsely punctate, the bounding 

 carina fairly prominent. Black; wings clear, except that they are slightly 

 fuscous apically; abdominal segments 1-3 largely reddish brown. Pile
