Black and somewhat shining, witli the abdomen usually broadly red. 

 Head distinctly constricted behind the eyes ; clypeus a little depressed 

 apically ; palpi pale flavous. Antennae dull testaceous beneath ; ^ with 

 the sixth to eighth flagellar joints somewhat dilated externally. Thorax 

 immaculate ; metanotum with its posterior angles obtusely dentate and 

 its disc not sulcate, of 9 nitidulous, sparsely punctate with the petiolar 

 area basally trituberculate, of J finely scabriculous with the tubercles 

 smaller. Abdomen alutaceo-punctate, hardly shining and usually red or 

 ferrugineous centrally, of ^ cylindrical and of 9 elongate-ovate ; basal 

 segment short and not longer than the hind coxae, with a broad and 

 deep basal fovea, but no dorsal carinae ; segments two to five strongly 

 punctate with their apices glabrous, and transversely incised before the 

 apices, with the lateral tubercles inconspicuous and indeterminate ; 

 terebra only a little shorter than the abdomen, with pilose valvulae. Legs 

 stout and pale red, with the coxae more or less basally black ; hind 

 tibiae externally and their tarsi dull ferrugineous, the former with a band 

 before the base and the latter with their joints basally white. Wings not 

 broad, hyaline and iridescent ; stigma and radius infuscate, radix and 

 often tegulae white ; areolet pentagonal, with the outer nervure entirely 

 wanting ; radial cell short, twice longer than broad, subtrapeziform and 

 not externally arcuate ; nervellus distinct, postfurcal, intercepting a little 

 above the centre. Length, 4 — 7 mm. 



This species, whose areolet is said by Thomson to resemble that of 

 I/iDiiltlis, may be recognised by the interception by the nervcllus above
