PHYGADEUON. 213 



Antennae thick, semi-involute, nearly as long as the thorax and abdomen together ; the 

 third joint a little longer than the fourth. Head thick, white, except the middle of the 

 vertex and the occiput ; clypeal foveae large ; face covered with a longish white pubes- 

 cence. Thorax impunctate ; metapleurae obscurely striated ; middle area on the meta- 

 notum broader than long, the other areae distinct; spiracular area obscurely trans- 

 versely striated. The prothorax is black, except the prosternum and a broad white line 

 on the pronotum ; the mesonotum is entirely black (unless the scutellum may be white, 

 a fact which I cannot make out, the large pin going through it) ; below the tegulae the 

 mesopleurae are, for the greater part, white ; the suture of the metapleurae is obscure 

 white; the metathoracic tubercles are large, semiacute. Abdomen shining, impunc- 

 tate. Legs stout ; four anterior coxae and trochanters yellowish-white, the rest of the 

 legs reddish. Areolet 5 -angled ; outer nervure bullated.

Antennae stout, involute ; the third joint not much longer than the fourth ; the others 

 becoming gradually shorter and a little thicker towards the apex. Head and thorax 

 finely punctured, opaque ; the clypeus shining, impunctate ; mandibles black at the 

 apex. Mesonotum more shining than the pleurae, and less strongly punctured; 

 covered with pale pubescence. Metathorax longish, the apex with an oblique slope, 

 its centre hollowed and transversely striated ; the upper median area longer than broad, 

 its apex transverse and narrower than the central part ; the base triangular ; without 

 tubercles. Postpetiole aciculate ; the rest of the abdomen obscurely aciculated to the 

 apex, which is shining and covered with longish white pubescence, the apex itself 

 obliquely truncated ; the ovipositor a little longer than the abdomen. Areolet broader 

 than long ; the outer nervure semiobsolete. Legs stout ; the trochanters, hind coxae, 

 and femora more or less blackish.
