234 P- CAMERON. HYMENOPTERA. 



Length 9 m. m., terebra 7 mm. 



Neither the mesonotum nor the scutellum is quite flat, the central basai part of the 

 former and the latter being slightly raised. 



Camploneurus Szép. 



This genus was formed in 1900 (Termes. Fùzek., XXIII, 51) on a species from New 

 Guinea, [bicolor, Szép.). Mr. H. L. Viereck, Bull. U. S. Nat. Mus., 1911, 476) states that 

 v Cyauopterus, Haliday is the same as Camploneurus, Szépligeti, at least in part". He proposes 

 to retain the name Camploneurus provisionally for the species that hâve at least the second 

 abdominal segment coarsely sculptured, as is the case with C. tricolor, Szép. from New Guinea. 

 If the puncturing of the abdomen is to be regarded as a generic character then the species, 

 I hâve described hère cannot be referred to Camploneurus, the abdomen on them being 

 smooth, except the furrows bordering the area and the suturiform articulation. Cyanopterus 

 Hal., as defined by Szépligeti, cannot be used for my species as it has a tooth on the 

 underside of the antennal scape and has the abdominal sutures smooth. It may be that my 

 New Guinea species represents a 3 rd genus. They are ail pretty much alike as regards colour- 

 ation, having the head, thorax, legs, and, it may be, the i$t abdominal segment wholly or 

 in part red, and the area on the 2 nd segment may be red. Ail the species hâve the transverse 

 médian nervure received shortly beyond the transverse basai and the basai abscissa of the 

 cubitus is broadly or acutely angled at the base, not straight, oblique and interstitial as in 

 Bracon; the anal nervure in ail my species issues from near the top of the hinder third of 

 the nervure. The area on the 2°<i abdominal segment may be semicircular or triangular.
