Dorsuluiu finely and closely punctured along tbe middle. More polished and 

 with the punctures sparse. Scutellum uniformly, jather closely punctured. The 

 metathorax above finely granulated, the metapleura distinctly striated. The 

 posterior aspect of the metathorax has the metanotum somewhat overhanging in 

 the form of a ridge. The posterior aspect of the metanotum is more closely stri- 

 ated than the metapleura, and on the basal half has a deep oval depression. 

 Pygidial area a little more than twice as long as wide at base and with sparse^ 

 small, shallow punctures. Head and thorax black. Mandibles and tarsi more or 

 less brownish. Wings with a faint brownish tinge, uervures brown, stigma 

 brownish testaceous. Abdomen testaceo-castaneous, more or less covered with 

 silvery, appressed pubescence, which is more conspicuous on the lower half of the 

 face, on the pleura, margins of the thorax, metathorax and along the apical mar- 

 gins of the abdominal segments and laterally when held in certain lights. 



Type. — University of Kansas. 



Type locality. — Hamilton Co., 3350 ft., Kansas. 



One female, collected by F. H. Snow. 



Tachyspliex clarcoiiis n. sp. 



Related to tenninatus. 



9- — 7 mm. — Anterior margin of clypeus as in terminafus. Front finely granu- 

 lated, the sculpture practically obscured by the rather dense appressed silvery 

 pubescence. The occiput between the eyes somewhat depressed, making a shal- 

 low emargination. Space between the eyes at top a little more than half the 

 distance between the eyes at the bottom. Third joint of the antennse approxi- 

 mately three-fourths the length of the fourth joint. The fourth joint apparently 

 a little longer than the fifth, the fifth and succeeding joints subequal. Dorsulum 

 shining, with small distinct almost adjoining punctures. Pygidial area less dis- 

 tinctly punctured than the dorsulum and with the punctures well separated. 



Color. — Black. Abdomen reddish, with the venter brownish. 



Ty})e. — University of Kansas. 



Type locality. — Clark Co., Kansas, 1962 ft. 



One female collected in May, by F. H. Snow. 



Tachysphex intermedins n. sp. 



Related to punctifrons and <ethiops. 



% .—8.5 mm.— Asiterior margins of the clypeus rounded, having no large tooth 

 laterally. Front dullish, very finely roughened and appearing punctate. A 

 shallow groove extending the greater distance between the insertion of the an- 

 tennae and the anterior ocellus along the middle line. The distance between the 

 eyes above approximately as great as one-half the distance between the eyes 

 below. Third joint of the antennae a little shorter than the fourth, the fourth 

 and succeeding joints subequal. Dorsulum shining and rather indistinctly punc- 

 tured, the punctures well separated. The anterior third along the middle line 

 there is a longitudinal elevation. Scutellum shining and punctured in much the 

 same way as the dorsulum. Metathorax dullish and apparently impunctate,
