Sphex (Parapsammophila) testaceipes, sp. n. 



d . Niger, albo-pilosus ; mandibulis, apice excepto, clypeo in medio 

 nigro-lineato, tegulis, pedibusque rufo-tcstaceis ; coxis posticis, 

 trochanteribus femoribusque posticis supra, tarsis intermediis 

 posticisque arfciculo apicali, unguiculisque nigris ; alis hyalinis, 

 venis fusco-ferrugineis. 



Long. 25 inm. 



<$ . Clypeus broadly rounded at the apex, subdenticulate 

 in the middle of the apical margin, clothed with delicate 

 silver pubescence, which extends on to the front. Head 

 and sides of the thorax rather densely clothed with long- 

 white hairs, the hairs on the mesonotum and dorsal surface 

 of the median segment cinereous. Eyes convergent towards 

 the clypeus, where they are separated by a distance slightly 

 exceeding twice the length of the scape and first joint of 

 the flagellum combined. Posterior ocelli separated from 

 the eyes by a distance scarcely equal to the length of the 

 third joint of the flagellum. Head and pronotum punctured- 

 rugulose, the clypeus shining and almost smooth ; meso- 

 notum rugulose ; dorsal surface of median segment closely 

 transversely striate, the striae slightly curved in the middle. 

 First joint of the petiole a little longer than the hind femur ; 

 second tergite longer than the apical breadth; seventh 

 tergite broadly truncate at the apex; eighth sternite long, 

 the sides almost parallel, the apex rather broadly truncate. 

 Mesosternum not produced anteriorly. Tarsal ungues with 

 two teeth close to the base; pulvilli large. Second re- 

 current nervure almost interstitial with the second trans- 

 verse cubital nervure ; second abscissa of the radius much 

 longer than the third, third transverse cubital nervure rather 

 strongly curved outwardly in the middle. 



Hab. Valley of the Ruaha River, German East Africa 

 (S. A. Neave), December 1910. 



This has somewhat the build of S. dives, BoiUe, but may 

 easily be distinguished by the colour of the legs, the form of 

 the apical segments, the broader head and clypeus, and the 

 sculpture of the median segment, also by the presence of 

 two teeth on the tarsal ungues.
