 Areolet 5-angled ; the recurrent nervure is received in the middle ; 

 the disco-cubital nervure has a minute stump behind the middle ;

Black, shining, the underside of the antennal scape, the face, 

 •clypeus, mandibles except the apex, and palpi, yellow, tinged with 

 orange ; the second and following segments of the abdomen red, 

 largely tinged with black in the middle ; the legs of a brighter rufous

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

 black, the stigma fuscous. <? . 



Length 5 mm. 



Antennae stout, tapering towards the apex ; the basal half of the 

 nagellum fuscous below. Face closely and distinctly ; the clypeus 

 less closely, punctured ; it is clearly separated from the face by a 

 furrow. Front and vertex distinctly punctured ; the former is more 

 opaque and more closely punctured than the latter. Thorax shining, 

 closely punctured, sparsely pilose ; the parapsidal furrows are on the 

 basal third ; the mesosternal furrow is wide, crenulated ; the upper, 

 apical part of the mesopleurae is almost smooth. Scutellum pro- 

 minent ; its sides keeled on the basal half. Basal slope of metanotum 

 depressed, oblique, smooth, with only lateral keels ; the areola large, 

 roundly narrowed to a rounded point from shortly beyond the middle 

 to the base ; in its centre is a stout longitudinal keel ; the sides are 

 irregularly longitudinally striated ; the apex is slightly rounded 

 inwardly ; there are five clearly defined apical areae, all strongly 

 striated, except the posterior median at the top ; the spiracular area 

 is clearly defined and closely striated ; the metapleurae are irregularly 

 striated towards the apex ; below is a stout curved keel, there being 

 also a stout keel between the coxae. Abdomen closely and rather 

 strongly punctured, including the post-petiole, which has prominent 

 spiracles ; the sides behind these are keeled, the keels extending 

 slightly on to the post-petiole beyond them. Areolet 5-angled,
