antennae have the flagellum "blackish above, fulvous beneath," and the posterior 

 femora bear more black, including three spots on inner side.

The face and underside of the scape are pallid yellow, the latter is hollowed on the 

 outerside at the apex. The transverse furrow over the mouth is broad and deep ; the 

 foveae at side of the clypeus deep, sharp at the ends, and half the length of the transverse 

 groove. The face below the antennae projects broadly, there being no keel; the head 

 above the antennae is deeply excavated, the excavation reaching to the lower ocellus ; 

 it also extends a little below the antennae. Lower part of the head smooth, shining, 

 the upper coarsely punctured. Pro- and mesonotum coarsely punctured, and covered 

 (as is also the vertex) with long black hairs; the mesopleura in the centre deeply 

 excavated, smooth, shining, impunctate ; the rest of pleurae coarsely punctured. The 

 scutellum, as usual, is margined, and at the apex ends in two blunt teeth. The meta- 

 thorax is reticulated into wide areas ; in the centre is an irregular furrow, which widens 

 in the centre, where there is, on each side of it, a narrow area ; the upper area is large, 

 pentagonal. 



The teeth on side of the metathorax are mere rugosities, except the lowest ; the hair 

 on the metapleura is partly in tufts. The pronotum bears a narrow black line on either 

 side ; there is a short black transverse one on middle lobe of the mesonotum, a smaller 

 round one at the sides, and a broad triangular one on apex of the scutellum ; the hollow 

 middle of the mesopleura is for the most part black. The abdomen is smooth, shining, 

 impunctate, and of a lighter tint than the thorax ; it is a little shorter than the head 

 and thorax. The apical and middle segments are fuscous at the junction of the seg- 

 ments ; ovipositor black ; the apical segments covered with short black hair. Petiole 

 thick, double long as broad. 



The legs are of a paler tint than the thorax ; on the upperside of the posterior coxae 

 is a broad black line which, at the apex, is continued all round as a black ring ; the 

 trochanters are for the greater part black ; on the outer side of the femora, between the 

 two apical teeth, is a black mark which is longer than broad. On the inner side above, 

 extending from a little beyond the middle, is a broad black line, and there is a shorter
