Hymenoptera Orientalis. 467 



segment shorter than the mesothorax, with a gentle slope, 

 the apex oblique. Abdomen sessile ; the apical segment 

 citron-yellow, densely covered with a pale pubescence, and 

 at the apex with longish black hairs. Legs stout ; the tibiae 

 and tarsi with few spines ; the claws bifid, the shorter claw 

 much thicker than the other. Antennae longish, stout, the 

 apical joints dilated beneath. Basal nervure interstitial ; 

 the anal in hind wing being received beyond the cubital. 

 (For neuration see pi. III. f. 12). Length 11 mm. $. Claws 

 with the basal tooth stout, not reaching to the apex. 



In one specimen the hinder tibiae are whitish-yellow at 

 the base, the spurs being also of this colour. 



POMPILUS INCOGNITUS, sp. nov. (PI. III. f. 1 3). 



This species agree in the colouration of the body, legs, 

 and wings with P. pedestris^ Smith — having the body 

 densely cinereous pruinose, the hind femora and tibiae red, 

 the wings fusco-hyaline, deeply infuscated at the apex, and 

 the abdomen with cinereous bands ; but it must be, I should 

 think, distinct, e.g.^ although the apex of the median seg- 

 ment is truncated, yet it can hardly be said to be " produced 

 laterally, forming obtuse tubercles " ; and the third cubital 

 cellule is called " subtriangular," while here it is distinctly 

 petiolated and not sub-triangular. 



Eyes distinctly converging beneath ; ocelli separated 

 from the eyes by about the same distance they are 

 from each other. Clypeus a little convex, short, broad ; 

 the apex transverse. Head very little developed behind 

 the eyes : the occiput a little concave. Prothorax 

 a little longer than the head, having a gradually rounded 

 slope towards the head, and sub-quadrate behind, arcuate, 

 angled in the middle. Median segment with a slight slope 

 to near the apex, when it becomes oblique ; the apex 

 transverse, bearing a thick silvery pubescence ; the meta- 

 pleurae projecting sharply at the apex into tubercles [this-
