Descriptions of New Species of Parasitic Hymcnoptcra. 83 



This species differs from the normal species of the genus in the 

 disco-cubital nervure being broadly rounded, not angled, and in the 

 transverse median nervure in the hind wings not being broken so 

 low down. The only African species of its size is Enicospilus 

 trimaculatus, Tosq. 



I have a ^ without note of a particular locality in my collection ; 

 it is about 30 mm. long. 



EUEYOPHION, gen. nov. 



Wings uniformly fuscous violaceous ; the base of radius thickened, 

 transverse median nervure received very shortly beyond the trans- 

 verse basal, almost interstitial ; radial cellule long, narrow. Disco- 

 cubital nervure not broken, the curve rounded ; not interstitial. 

 Transverse median nervure in hind wings broken in the middle. 

 Apex of clypeus transverse. Malar space very small. Eyes parallel, 

 not incised. Ocelli widely separated from each other, and, to a less 

 extent, from the eyes. Median segment bearing stout, irregular, 

 curved keels. Spiracles of second abdominal segment placed shortly 

 beyond the middle. Claws pectinated. Scutellum roundly convex, 

 its sides not keeled. Both the thorax and abdomen are stouter, 

 broader than usual. 



The apical abscissa of radius is not appreciably turned up towards 

 the costa as in Ophion, &c. ; the radial cellule is long and narrow. 

 The radius in the hind wings is thickened at the base. The trans- 

 verse basal nervure in fore wings is also thickened. Mesosternum 

 flat ; its sides bordered by a wide, shallow furrow, roundly narrowed 

 on the inner side. There are no blisters in the fore wings. 



A distinct genus. Characteristic are the blackish wings. Opiliion 

 differs in having the disco-cubital nervure broken by a stump of a 

 nervure, in the eyes converging above, in the basal abscissa of the 

 radius not being swollen, and in the metanotum being smooth, with 

 only a transverse keel. Pleuroneurophion has the basal abscissa of 

 the radius swollen (as has also Enicospilus, which has, however, 

 blisters in the wing) but the eyes distinctly converge above, the 

 disco-cubital nervure is sharply angled, the transverse median 

 nervure in hind wings is broken far, or at least distinctly, below the 

 middle, and the transverse median nervure is placed behind the 

 transverse basal. 



EURYOPHION NIGRIPENNIS, Sp. noV. 



Dark ferruginous, the third and following segments of the abdomen 

 black ; wings dark fuscous, tinged with violaceous, the nervures and
