 pro-thorax, mesonotum, and legs, with the exception of the coxae of 

 the intermediate and posterior pairs and the femora of the posterior 

 pair, testaceous-red. Head clothed with short fine pale hairs. Man- 

 dibles piceous towards the apex, inner margins of the eyes diverging 

 rapidly from the vertex then almost angulated and sub-parallel to 

 the clypeus ; cheeks between the eyes and mandibles scarcely de- 

 veloped, clypeus largely rounded in front ; distance of posterior 

 ocelli from each other about twice that between each and the eye 

 and between each and the anterior ocellus ; antennae with the 3rd 

 joint nearly twice as long as the 4th, the rest subequal ; pro- 

 thorax testaceous-red, sharply emarginate posteriorly ; pro-pleurae 

 clothed with long pale hairs ; mesonotum and scutellum coloured

 meso- and metapleurae black ; pleurae dull, smooth ; propodeum 

 densely clothed with matted short black hairs. Anterior metatarsi 

 bearing 4 long somewhat flattened and dilated spines, the basal one 

 much the shortest, and each subsequent spine longer in proportion to 

 its predecessor, the apical spine being as long as the next 2 joints 

 of the tarsi taken together ; 2nd and 3rd tarsal joints each with 2 

 long spines, 4th with one ; coxae of the posterior pair of legs and the 

 femora of the last pair black except the extreme apex of the latter ; 

 posterior tibiae with a few short, pale spines, posterior metatarsi as
