 but viewed from the side they are seen to have rather abundant short 

 fuscous hair ; mandibles black, ferruginous at apex ; labrum shining 

 black, strongly emarginate ; vertex granular ; antennae long and 

 slender, entirely black, third joint shorter than fourth ; mesothorax 

 dullish, minutely grauulo-punctate ; post-scutellum with a delicate 

 white tomentum ; sides of metathorax with a large patch of loose 

 white fluff; basal area of metathorax rather large, shining, with 

 numerous raised lines or keels, its hind margin in the middle with a 

 pair of rounded excavations ; tegulte rather large, deep red-brown, the 

 inner hind angle pointed ; wings hyaline, the apical margins faintly 

 dusky, stigma and nervures fuscous ; second submarginal cell higher 

 than broad, but not small, receiving the first recurrent nervure at its 

 apical corner ; legs black, with white pubescence, the basal part of the 

 claws ferruginous, the spurs light ferruginous ; second to fourth joints 

 of anterior tarsi triangular ; hind femora extremely swollen and con- 

 vex above, beneath with a concave area, flattened in a transverse 

 direction ; hind tibiae much thickened, with a large and a small tooth 

 beneath towards the base, and the spur-bearing apical lobe incrassated ; 

 abdomen minutely roughened, with a subsericeous surface, the apical 

 margin of the first segment minutely punctured, and having a little 

 patch of white hair at each extreme side ; the apical margins of the 

 second and following segments with bands of pure white hair, but that 

 on the second is extremely widely, that on the third rather widely, and 

 that on the fourth slightly, interrupted ; third ventral segment with a 

 pair of prominences, each terminating in a short sharp spine ; fourth 

 ventral segment emarginate, with the hind lateral angles pointed. 



Hah. Queensland (E. Saunders), 93. 49 ; also marked Hy,

 different colour, the hind femora do not present a large swelling 

 beneath, and the ferruginous colour on the legs is lacking.
