vertex with distinct punctures; occiput when viewed from behind 

 very slightly emarginate; space between the eyes at the top dis- 

 tinctly less than the length of antennal joints 3 and 4 united, but 

 still a little greater than the length of joints 2 and 3 united ; first joint 

 of the fiagellum about one- third shorter than the second; dor- 

 sulum with strong, tolerably well separated punctures, the 

 latter are however closer than in apicalis; upper surface of meta- 

 thorax finely reticulated or reticulato-granulated, the metapleurse 

 rather strongly striated ; tibiae and tarsi tolerably well armed with 

 spines ; pygidial area sparsely punctured, nearly three times as long 

 as it is broad at base. Black ; mandibles medially and scape be- 

 neath at apex, obscure reddish ; apex of abdomen not red; wings sub- 

 fuscous, iridescent, nervures black; marginal cell subtrimeate; width 

 of the second and third submarginal cells at the top variable, al- 

 though the second is usually greatest; face, front and clypeus with 

 silvery pubescence, that on the thorax sparser; abdomen with silvery 

 pile. Length 9 mm. 



£ . — Front even more finely punctured than in the 9 ; occiput 

 not or very indistinctly emarginate; space between the eyes at top 

 about equal to the length of antennal joints 2-4 united, at any rate 

 not greater; anterior margin of clypeus a little more strongly 

 rounded out than in the 9 ; antenna? tolerably long, not thickened, 

 the first joint of the fiagellum about one-third shorter than the sec- 

 ond; scutellum not impressed ; upper surface of metathorax rather 

 coarsely granulated, the metapleune finely striated; abdomen closely 

 and finely punctured ventrally; pubescence about as in the 9 ; 

 wings paler, the marginal cell more obtuse and narrower at apex. 

 Length 6 J mm.

21. — Tachysphex amplus n. sp. 



9 . — Anterior margin of clypeus rounded out, armed with a tooth 

 laterally; front rather strongly and closely punctured becoming 

 granulated towards insertion of antennas; vertex with distinct, toler- 

 ably close punctures; occiput not at all emarginate, in consequence 

 of the impressed line not being strong ; space between the eyes at top 

 about equal to the length of the third joint of antenme; first joint of 

 the fiagellum but little shorter than the second; dorsulum with tol-
