pubescence. Hinder ocelli separated from each other by a distin(;tlY 

 greater distance than they are from the eyes. Mesonotnm stron^rly, 

 but not closely punctured : the scutellummore sparsely i)uncturetl, 

 the sides almost smooth in the centie. Post-scutellum aciculated, 

 sparsely punctured. Metanotal area with some stout, irregular, 

 slightly oblique keels ; the part beyond it smooth, the rest of the 

 segment strongly punctured. Pleurae sparsely punciured, thickly 

 covered with white pubescence. First abdominal segment almost 

 smooth, the 2nd sparsely, the others more closely and distinctly 

 punctured. The recurrent nervures are received closely to each 

 other, beyond the middle of the cellule. The alar neuration is as 

 in H. quadrifasciatus Pz., cf. Kohl, Ann. K.K. Hof Mus. Wien, 

 XI, 415, fig. 60. The central keel on the metanotum is more 

 twisted than the others ; there are about 12 keels. The penultimate 

 joint of the antennae is hollowed beneath. Comes close to H. thalia, 

 Hand. In the male antennas of that species the 6th joint does not 

 project equally with the 5th as in Whitei ; the 7th, too, is clearly 

 narrowed below, while in my species it is of equal width above 

 and below, this being also the case with the 6th, which in tlialia 

 is distinctly narrower below than above. The basal joints of the 

 antennee in my species are stouter compared with the apical than 

 they are in thalia. Cf. Handlirsch, Ver. Z-B. Ges., Wien, 1901, 428. 

 Thalia, too, is a larger species and the cloud in the radial cellule 

 does not reach to the cubitus. The eyes in my species hardly 

 converge below. The striation on the median segment probably 

 varies. 



Tachysphex SchdnJajuii, sp. nov. 



Black, the basal half of the abdomen red : the apex of femora, 

 tibiai and tarsi rufo-testaceous, the spines paler : the front, face 

 and clypeus thickly covered with golden pubescence ; wings 

 hyaline, the nervures and stigma testaceous. Male. 



Length 10 mm.
