POMPILUS SEXSPINOSUS, n. sp. 



Niger, mandibulis in medio piceis, antennarum articulo tertio 

 elongato spatio inter-oculari longitudine fere aequali, prothorace 

 subangulatim emarginato, alis infu.matis cellulis subrnarginalibus 

 tribus instructis, tertia lata, apice constricto nervo externo in con- 

 vexum curvato, metatarsis anticis spinis longissimis sex instructis 

 apices versus subdilatatis ; mas capite et thorace dense villosis, 

 abdominis segmento quinto ventrali apice arcuato-emarginato, sexto 

 valde triangulariter exciso, utrinque foveola rotundata impresso, 

 octavo lato, carina valida centrali instructo. 



2 broad and rather short. Entirely black, except the piceous 

 centres of the mandibles, head slightly hairy, clypeus with the 

 anterior margin very slightly emarginate, and narrowly shining, eyes 

 subparallel, width between the posterior ocelli much longer than 

 that which separates them from the anterior ocellus, and slightly 

 longer than their distance from the eyes; antennae with the 3rd joint 

 long, about once and a half as long as the following, and nearly as 

 long as the width of the vertex between the eyes. Mandibles and 

 eyes contiguous ; thorax sparsely hairy, prothorax short and wide, its 

 sides subparallel, its posterior margin very obtusely subangulate ; 

 wings rather strongly infuscated, apical margin darker, with three 

 submarginal cells, the 2nd and 3rd subequal on their posterior 

 margins, the 3rd much constricted above, its outer nerve convexly 

 curved, posterior nerve of hind wing uniting with the median 

 beyond its branch ; propodeum deeply channelled in the centre, and 

 concave posteriorly, its sides rounded and clothed with erect hairs ; 

 abdomen clothed with a fine pubescence, changing colour according 

 as the light falls on it, apical segments above and all the segments 

 beneath with a few fine erect hairs. Anterior metatarsi with 6 very 

 long spines, the 5 lower ones of which are very slightly dilated 

 towards the apex. Claws toothed behind the middle. 



The $ taken with this $ has the head and thorax densely 

 clothed with long hairs, mandibles pieeous-red just before the 

 apex, antennae rather short for a $ of this genus, 3rd and 4W
