black hair; its base with a long, oblique slope. The pro- 

 pleurae and the upper part of the mesopleurae smooth; 

 the lower part of the latter with large, widely separated, 

 shallow punctures. Legs pale bone-yellow ; the base of 

 the coxae, the four anterior femora behind, and, to a less 

 extent, in front and the four anterior tibiae behind, black. 

 Wings at the base fuscous-violaceous, from the base of the 

 stigma dark violaceous; the hinder wings similarly 

 coloured but lighter in tint. The basal segment of the 

 abdomen bone-yellow, the middle dark blue, the apical 

 broken off. 



The apex of the abdomen is unfortunately broken off, 

 but the characters which remain are sufficiently distinct 

 from anything described to warrant the description of the 

 species. The four apical joints of the antennae are 

 compressed.

 roundly incised, the latter yellowish ; the apex of the 

 mandibles black. On the thorax there are two large 

 marks on the lateral lobes of the mesonotum, the greater 

 part of the propleurae, more or less of the apex of the 

 meso- and the base of the meta-pleurae, black. Meso-
