A black and deplanate species, with only tarsi and flagellum pure white- 
banded. Head transverse and a little constricted posteriorly, somewhat 
dull; vertex centrally emarginate; clypeus short, apically rounded, 
strongly and sparsely punctate; palpi black, mandibles sometimes piceous. 
Antennae filiform, slender and apically subattenuate, black, at least in 9 
with the twefth to seventeenth joints white, and the apex beneath testa- 
ceous. ‘Thorax immaculate black and finely punctate; metanotum disc- 
ally bicarinate, with petiolar area small and entire. Abdomen deplanate, 
nitidulous and entirely black; basal segment petiolate and very smooth ; 
terebra slightly exserted. Legs slender and black with the front tibiae 
and often apices of their femora red; intermediate tibiae more or less 
broadly ferrugineous; front tarsi dark red, and the posterior with second 
to fourth joints white. Wings somewhat clouded with the stigma, radius, 
radix and tegulae infuscate; the areolet irregularly triangular and sessile, 
externally pellucid below and subcontinuous with the broadly unifenes- 
trate recurrent nervure; nervellus opposite. Length, rr mm. 
Stephens’ type, in Mus. Brit., is a somewhat pale ? of the present 
species from which it differs only in having the palpi white, the anterior 
femora more broadly testaceous and the second to fourth segments very 
darkly and indefinitely badious; the venation and thoracic conformation 
are entirely normal, with areolet not petiolate; the hind legs are wanting,
