Wasps uf the Genus Tacliytes. 13 



7. Tachytes neavei, sp. n. 



c? . N'iger ; mandibiilis in medio, tej2:ulisqne apico fuscis ; tarsis 

 fusco-ferrugiueis ; segmentis abdominalibus marg-iue apicali 

 brunneis, segmentis dorsalibus dense aureo-sei-iceis, fasciis 

 apicalibns distinctis ; alis subhyalinis, margine apicali leviter 

 infumatis, veuis ferrngiueis. 



Long. 18 mm. 



S . Clypeus broadly subtruncate at the apex ; eyes very 

 close together on the vertex, separated by a distance not 

 exceeding the length of the first joint ot" the flagellum. 

 Front and clypeus clothed with whitish pubescence. Second 

 joint of the flagellum longer by about one-quarter than the 

 third, joiuts 3-7 veiy distinctly arcuate beneath. Thorax 

 clothed with greyish mingled with pale fulvous hairs, the 

 punctures very minute. Median segment shorter than the 

 niesonotum, but nearly twice as long as the scutellum. 

 Second sternite very closely and finely punctured, more 

 strongly in the middle than on the sides. Seventh tergite 

 very broad, nearly as broad as the greatest length, very 

 broadly rounded at the apex, rather thinly clothed with pale 

 golden setae, each of which springs from a large puncture ; 

 eighth sternite broadly and shallowly emarginate at the 

 apex, the angles not forming distinct teeth. Third cubital 

 cell not extending as far as the radial, scarcely more than 

 half as long on the cubitus as the second, third abscissa of 

 the radius a little longer than the second, about equal to the 

 first. 



Hub. Lualaba River, 2500-4000 ft. {S. A. Neave), May. 



The eyes are even closer together on the vertex than in 

 ohservabilis, but the anal segments are nearer to mira, 

 though the seventh tergite is less distinctly rounded, and 

 the eightii sternite less deeply emarginate than in that 

 species. In the arcuate joints of the flagellum it differs 

 from both species. 



8. Tachytes velox, Sm. 

 Tachytes velox, Sm. Oat. Hymen. B.M. iv. p. 301 (ISoG). 



$ . Closely resembles T. basilica, with which it occurs ; 

 but the antennae are black ; the abdominal segments are 

 black, very narrowly brown on the apical margins, and the 

 legs are black with the apical joints of the tarsi fusco- 

 ferruginous. Eyes separated on the vertex by a distance 

 equal to the length of the two basal joints of the flagellum ;
