Mr. R. C. L. Perkins on Hawaiian Ophioninae. 529 



ment nearly black, its apex and the rest of the abdomen 

 brown; face apparently without whitish orbital mark- 

 ings, the space between the ocelli dull and densely, 

 microscopically granular, unlike any other species. 

 Wings clear light-fuscous ; propodeum shallowly rugose- 

 punctate to the base and without a carina ; scutellum 

 dull and very densely sculptured; discocubital ner- 

 vure not angulate but rounded at its highest point, 

 sinuated. The $ is unknown, as is the range of 

 variation. ) E. pseudonymus, sp. noVc 



The other genera of Ophionines contain few species, the 

 separation of which presents no difficulties at present, but 

 the genera themselves are of extreme interest and contain 

 the most interesting forms of the tribe Ophionini that are 

 yet known. They may be distinguished by the following 

 table. I have not seen the typical species of Eremotylus, 

 Forst., and I think that Ashmead is wrong in attributing 

 the one variable Hawaiian species to it. 



Table of Hawaiian Genera of Ophionini. 



1. (6) Transverse median nervure in the hind-wings angulated 



far below the middle, at | of its length from the upper 

 extremity at least or even much lower than this. Disco - 

 cubital cell (except in one species of Enicospilus) with 

 a distinct glabrous area beneath the radius basally. 



2. (5) Abdomen of normal shape not very long and in side view 



the 5th segment is not strongly elongate. 



3. (4) Cubitus and recurrent nervure distinct, forming a distinct 



angle at their meeting, the cubitus continued basally 

 beyond this point to form a conspicuous thick projection, 

 the discoidal cell consequently being conspicuously 

 pentagonal ; $ with ovipositor and sheaths prominently 

 exserted behind the abdomen. 



(Front wings with a glabrous area and usually with a 

 minute, translucent chitinous spot.) 



Pleuraiieurophion, Aslim. 



4. (3) Cubitus and recurrent nervure usually forming a curve at 



their meeting, rarely an angle ; in the latter case without 

 a large thickened projection at the angulation and with 

 the lower and upper sides of the discoidal cell subparallel, 

 instead of strongly divergent basally as in the preceding ; 

 $ with normal ovipositor, not exserted behind the apex 

 of the abdomen dorsally Enicospilus, Auct.
