c? . This is very near the male of claripennis, but may be 

 distinguished by the less elongate petiole, the narrow basal 

 portion of which is scarcely more than half as long as the 

 moderately swollen apical portion of the segment.

5 . Differs from petiolata as noticed under that species. 

 Bingham's description of the species is inaccurate as to the 

 median segment, and this has misled Nurse. The segment is not 

 smooth and shining, and the longitudintil impression, though 

 not very long, cannot be said to be triangulari 



S . The male, which has not been previously described, closely 

 resembles petiolata Sm. Head and thorax closely punctured, 

 most coarsely on the front, median segment rugose; abdomen 

 veiy slender, shining, minutely punctured. First abdominal 

 segment more than half as long again as the hind femur, the 

 narrow petiole very little shorter than the feebly swollen apical 

 portion ; second segment very narrow at the base, nearly half as 

 long again as the third segment. Seventh dorsal segment not 

 incised at the apex, pointed, convex and without a distinct 

 pygidial are^. 



Black ; mandibles, clypeus^ the apex of the interantennal 

 prominence, posterior margin of the pronotum, an apical narrow- 

 band on dorsal segments 1-6, strongly bisinuate on segments 

 2-6, base of the tegulse, fore tarsi, antei"ior and intermediate 

 tibise in front, base of hind tibise and base of intermediate and 

 hind tai'si pale yellow. Wings hyaline, nervures fuscous. 



Length, J 8 mm., § 10 mm. 



Hah. Burma, Ceylon, Bengal j and Defesa. 



The male has the two basal abdominal segments mOre slender 

 than in petiolata, the first with the apical portion less swollen, 

 the basal narrow petiole longer in proportion ; the second 

 narrower at the base.

5 . This is nearest to claripennis Bingh., but is a larger and 

 more robust species, somewhat more closely punctured, with the 

 wings distinctly darker and the punctures oh the abdomen 

 larger.
