PHYTOPHAGOUS AND PARASITIC HYMENOPTERA. 89 



Length 9 mm. 

 Kandy, June. 



Shining, thickly covered with white pnbescence, Parapsidal 

 furrows deep, the middle lobe of mesonotum clearly raised. 

 Base of propleurse with three stout keels, the middle one not 

 reaching, like the others, to the lower edge. Scutellar depression 

 large, deep, with a stout central keel and a narrower oblique one 

 on either side. Metanotum with four arese on the centre of the 

 basal region ; the basal large, longer than broad, the apical 

 smaller, dilated on the outer side ; the other areas not clearly 

 defined. The apical lateral teeth are large, longer than the width 

 at the base ; they become gradually narrowed, with the apex 

 rounded. First abdominal segment irregularly reticulated, the 

 sides less strongly than the centre ; the second is also irregularly 

 reticulated; there is a keel down the centre, reaching to the apex; 

 the lateral keels are stouter and shorter. Suturiform articulation 

 stoutly, closely striated. The apical depression of the middle 

 lobe of mesonotum is reticulated ; there is a distinct furrow on 

 the apex of the middle lobe. Metasternum bordered by a stout 

 keel. 



Holcobracon, gen. nov. 

 Lower part of mesopleurse with a distinct crenulated furrow. 

 Median segment closely reticulated, keeled down the middle ; 

 the sides at the apex below projecting into a blunt tubercle. 

 Mandibles stout, edentate, the apex transverse in front, oblique, 

 the basal half slightly roundly incised. Clypeus separated from 

 the face by a depression, roundly convex, thickly covered with 

 long hair. Malar space longer than the eyes. Temples broad. 

 Occiput margined, more distinctly on the sides than above ; 

 roundly incised. Scutellum flat, legs stout ; the fore coxae 

 largely project below, the trochanters issuing from the upper 

 part ; fore tibiae stoutly toothed. Anal nervure in fore wings 

 interstitial ; in the hind wings there is a discoidal nervure which 

 runs from the praediscoidal to the apex, there being thus three 

 longitudinal nervures in the hind wings ; there is a large 

 closed praebrachial cellule, which becomes gradually wider 

 towards the apex. Abdomen broad, the basal segments closely 

 striated ; suturiform articulation deep, roundly curved. 



The apical abscissa of radius reaches to the apex of the wings 

 and is twice the length of the second ; the transverse median 

 nervure is received distinctly beyond the transverse basal ; the 

 recurrent in the first cubital cellule. 



There are three genera known to me which possess the anomalon s 

 character of having a curved nervure issuing from the praebrachial
