PHYTOPHAGOFS AND PARASTTTO HYMENOPTERA. 113 



The areolet is minute, closed at the apex ; the transverse median 

 nervure is received behind the transverse basal ; the transverse 

 median nervure in hind wings broken below the middle. Antennae 

 long, ringed with white, slender. Metapleural keel reaching close to 

 the hind coxae. Temples very short, obliquely narrowed. Head not 

 much wider than the thorax. The basal transverse keel on the meta- 

 notum is only indicated in the middle. 



This species may be separated from the type of the genus thus : — 



Metanotal teeth stout ; metanotum with three yellow marks in a 

 triangle ; the mark on the mesonotum oval, longer than 

 broad, hind tarsi iuscoufi, olbomaculattis, Cam. 

 Metanotal teeth small ; metanotum with the upper part of the 

 apical slope margined with yellow ; the mark on the meso- 

 notum transverse, small, broader than long, erythropus. Cam. 

 In albomaculatus the clypeus is more convex and not so ; ransverse 

 at the apex. In Fenenias the front is more deeply and widely depress- 

 ed, the depression reaching closer to the ocelli, than in Skeatia.

 Plate A, fig. 12. 



Black, face, clypeus, base of mandibles, palpi, the inner eye orbits 

 to the end of their top, the outer from near the top, the yellow line 

 becoming gradually wider, malar space, the base of the prothorax 

 narrowly, the middle of pronotum broadly, tegulse, a mark, longer 

 than broad and of equal width in the centre of the mesonotum, 

 scutellar keels, scutellum, a triangular mark — the narrow end 

 above — its base shorter than the sides and laterally united by a 

 short line to a large mark on the sides of the apical slope, enclosing 

 the spines and going on to the pleurae, the apices of all the abdominal 

 segments, tubercles, a large oblique mark on the centre of the meso- 

 pleurse, roundly contracted above and below and narrowed at the 

 apex, mesosternum, and a mark on the metapleurae below the keel, 

 widest and oblique at the apex, yellow. Antennae broadly ringed 

 with white in the middle. Legs rufous, tlie coxae and trochanters 

 yellow, the hind coxae broadly black at the apex above, this part 

 joined to the base on the lower side by a broad curved line ; the apex 

 of the hind femora narrowly, the base of the tibiae still more narrowly, 

 their apex more broadly and the apical joints of their tarsi, black : 

 the hind tibiae are infuscated. Wings hyaline, the nervures and 

 stigma black ; areolet minute, longei- than wide, 9. 



Length 12 mm.: terebra 8-4 mm. 



Kandy, July. 



Fiont irregularly rugosely punctured except below tlie ocelli; the 

 centre keeled. Face distinctly, but not very closely, punctured; 

 the clypeus more sparsely punctured above, smooth below. Thorax
