 o . Form moderately stout. Anterior margin of clypeus broadly 

 subtruncate, the sides rounded (when the clypeus is viewed a little from 

 below it is broadly and shallowly emarginate), rim narrow; labrum a 

 little bilobed mesad; inner eye margins parallel; frons (up to the an- 

 terior ocellus) a little longer than broad, and with a faint indication 

 of an impressed median line; ocelli forming a low triangle; antennae 

 rather slender, somewhat thickened apically, joint 3 one-fourth longer 

 than 4; head shining, with large scattered punctures and very fine close 

 ones. Scutum and scutellum punctate about as in head, the suture be- 

 tween the two sclerites foveolate; pleura with fine close punctures and 

 large scattered ones; mesopleurae and metapleur* with a distinct suture 

 between them; mesopleurae separated from the mesosternum by a carina 

 extending from the middle coxae to the prothoracic tubercles. Wings 

 not extending to tip of abdomen; primaries with a rather weak stigma; 

 the marginal cell pointed apically, the second submarginal cell receiving 

 both recurrent nervures, the third submarginal extending a little be- 

 yond the marginal, and the submedian cell longer than the median along 

 the externo -medial nervure; secondaries with the cubitus originating well 

 beyond the submedian cell. Legs moderately stout and spinose, the 

 fossorial comb (on fore legs) well developed. Disc of propodeum with 

 the enclosed triangle bearing about fourteen carinse, all basad except 

 the two forming the median furrow; these two extend rather irregularly
