somewhat large. Scutellum and postscutellum white, normal and 

 sparsely punctate. Abdomen linear, nearly half as long again as 

 head and thorax, though much narrower, glittering, irapune- 

 tate, white, with the basal half of the first seven segments, 

 together with the first ventral basally, black; first segment 

 three and a half times as long as apically broad, very gradually 

 explanate throughout and black only to the spiracles, which are 

 set in a strong hump distinctly before its centre. Legs elongate, 

 slender, normal, black, with the trochanters, anterior coxae, apices 

 of femora and of the anterior tibiae and tarsi, base of the hind 

 tibia and whole of their tarsi, white ; all the claws simple, strong 

 and infuscate ; hind femora and their coxae simple and punctate. 

 Wings ample and not narrow, siliceous, with no areolet ; second 

 recurrent nervure strongly curved, narrowly bifenestrate and 

 emitted slightly beyond the submarginal ; nervelet short but 

 distinct ; basal nervure subcontinuous ; stigma, radix and tegulae 

 black ; nervellus opposite and intercepted exactly in its centre.

Head distinctly narrow behind the large and basally sub- 

 convergent eyes ; cheeks distinct ; clypeus evenly convex, apically 

 broadly rounded and basally discrete ; occiput transverse and 

 close to ocelli. Antennae nearly as long as the body, with the 

 apical joint longer than the penultimate, but shorter than the two 

 preceding united. Metathorax evenly coriaceous throughout, 

 with no trace of transverse carinae ; lateral metapleural carinae 

 strong ; " the keel on the edge of the metasternum projects at the 

 apex into a distinct tooth" ; spiracles small and oval. Abdominal 

 petiole elongate and slender, basally constricted and as long as 

 the two following segments united ; all the segments glabrous, 

 nitidulous and longer than broad ; terebra longer than half the 

 body. Legs slender ; hind coxae thrice as long as broad ; claws 

 not pectinate. Wings with the areolet elongately petiolate, 

 emitting the recurrent nervure from its apex ; inner cubital 

 nervure evenly curved ; upper basal emitted from the median 

 beyond the lower basal.

" The abdominal petiole is longer, more slender and narrower
