covered with a short white pubescence. iNIandibles deeply bidentate, the apex blackish : 

 foveae above face not very deep, longer than broad ; covered with a white pubescence. 

 Antennae a little longer than the body. Mesonotum almost shining, very finely 

 punctured ; mesonotum distinctly bordered all round ; from the tegulae the carina curves 

 round to the scutellum, along the side of which it goes to the end, the two keels 

 converging as they do so, but not joining ; the apex of the mesonotum is also bordered, 

 and there is a lateral keel at the side of the scutellum in front behind the fore wings. 

 The metanotum is more pilose than the mesonotum ; it is finely rugose all over ; at the 

 base is a waved indistinct furrow. Abdomen covered with long, depressed, white hairs, 

 especially at the apex ; the ventral surface is darker than the rest. The long spur of 

 the posterior tibiae is longer than the 2nd tarsal joint. Female and male. (Cameron.)

%. Length 9-5 mm. Head obscure yellowish-white, the occiput fuscous ; teeth of 

 mandibles black ; palpi brownish-yellow ; ocelli large, arranged in a triangle ; eyes large, 

 extending almost to the base of the mandibles and sinuate within opposite the insertion 

 of the antennae ; antennae black, the scape, the pedicel and the ring-joints at apex and 

 beneath, ferruginous ; the thorax, the co.xae and more or less of the trochanters, except 

 their sutures, which are whitish, and the hind femora, black, rest of legs brownish or 

 fuscous. Wings hyaline, the stigma and veins brown, except a whitish spot between 

 the parastigma and the stigma ; the stigma is lanceolate, the first abscissa of the radius 

 being much swollen beyond its origin but becoming slender at tip ; marginal cell long, 

 while the cubitus is distinctly angulated. The abdomen is nearly twice as long as the 

 head and thorax united, compressed and shaped as in Anoma/on, the ovipositor exserted 

 but short, not so long as the first joint of the hind tarsi. The head is smooth, 

 impunctate ; the me.sothorax above is nearly smooth but distincdy sculptured at the 

 sides, while the metathorax is rugulose, with one transverse carina, the space enclosed 

 by it being much smoother than the portion beyond.
