414 NEW SPECIES OF HYMENOPTERA 



likewise but the punctures are much finer; on the vertex the punctures are 

 separated, not appearing granulate; mesoscutum closely and finely punctured, 

 the episterna very finely granulate; mesoscutellum with fine separate punctures, 

 the latter about their own diameter apart; disc of propodeum finely rugose 

 medially, granulate at the sides; the sides of the propodeum granulate and the 

 posterior face rather coarsely, transversely rugose; the fovea smooth, moder- 

 ately deep and longer than wide; legs strongly spinose; the longer spur of the 

 hind tibiae shorter than the basitarsus; wings large, subfuscous; the marginal 

 cell quite broadly and obliquely truncate, the second submarginal cell slightly 

 wider on the radial vein than the third submarginal; abdomen stout, about 

 the length of the head and thorax combined; pygidial area well defined, about 

 twice as long as it is broad at the base, narrowly truncate at the apex, with a 

 few scattered, shallow punctures; sternites two to five each with a transverse 

 row of large shallow punctures near the apex. Black; tarsi slightly reddish, 

 tegulae dark testaceous, two basal segments of abdomen reddish, third seg- 

 ment obscurely reddish. Front with rather fine, thin, silvery pile; remainder 

 of body with a sparse silvery pile; the abdominal tergites not silvery fasciate. 

 cf . Unknown. 



Type, a female taken at Glen, Nebraska, August 15, 1906, 

 (P. R. Jones). 



Probably related to tarsatus, from which it differs in punctua- 

 tion, in the sculpture of the propodeum, in the color of the wings 

 and in the coloration of the abdomen. 



Tachysphex sanguinosus sp. nov. 



9 . Length 12 to 14 mm. Medium stout. Anterior margin of clj'peus 

 rounded, with a strong lateral tooth, and emarginate medially; apical half of 

 clypeus polished, shining; the clypeus throughout with a number of large, 

 shallow punctures; on the basal half these large punctures are interspersed 

 with close, fine punctures; antennae normal, not thickened medially, joint two 

 less than one-half as long as joint three, which is about three-fourths as long 

 as joint four; the interocular space at the vertex is about equal to the com- 

 bined length of antennal joints two and three; front finely and denselj^ punc- 

 tured, appearing granular; interocellar space with close, minute but separate 

 punctures; vertex with fine, separate punctures; mesoscutum and mesoscu- 

 tellum with fine, very close punctures, the episterna granulate; disc of propo- 

 deum granulate throughout; sides and posterior face of propodeum strongly, 

 transversely striate; a strong carina separates the disc of the propodeum from 

 the posterior face; fovea wedge-shaped, large and smooth; legs strongly spinose, 

 the longer spur of the hind tibiae shorter than the basitarsus; wings large, 

 hyaline, the marginal cell l)roadly and obliquely truncate at the apex, the 

 second and third submarginal cells about equal in length on the radial vein; 

 abdomen moderately stout, about as long as the combined length of the head 

 and thorax; pygidial area not well defined; about twice as long as it is broad 

 at the base, with a few obscuie scattered punctures. Black; tarsi shghtly
