Podium (Trigonopsis) longipilosellum. sp.n. 
Black, the head and thorax densely covered with long hair, white except on 
the front and vertex, hinder by a distinctly greater distance than these are 
fromeach. There is a broad ferrugimous band near the apex of the mandibles. 
There is a furrow in the middle of the apex of the pronotum and a narrower, 
more clearly defined one in the centre of the basal third of the mesonotum. 
Prothorax almost smooth, the mesonotum sparsely, weakly, the pleure more 
closely and strongly punctured, the latter more strongly below, the metanotum 
more strongly and closely punctured, the apical slope irregularly transversely 
striated, where it is darker coloured ; the apical half of the 4 anterior femora 
in front and narrowly behind, almost the apical half of the hinder. All the tibie 
except the posterior narrowly behind and the anterior tarsi rufo-testaceous ; 
the wings hyaline, the nervures and stigma black, a narrow cloud along the 
transverse basal nervure and transverse median, wiaer along the inner than 
along the outerside, the whole of the radial cellule, the apex of 1st cubital 
nairowly, the cloud wider in front, the 2nd cubital cellule entirely, the 3rd to the 
end of the 3rd abscissa of the vadius, a cloud along the apex commencing at 
the end of the radius, the cloud in the 2nd and 38rd cubital cellules extends 
into the discoidal cellules to near the apex of the 2nd recurrent and extending 
beyond it, and the apex of the hinder wings is smoky. Female. 
Length 17 mm. 
Apex of clypeus armed with 5 almost equally-sized teeth, which become 
slightly narrowed towards the apex. Eyes distinctly converging above. 
There is a shallow closely transversely striated furrow down the apical 
two-thirds of the basal part of the metanotum, the apical slope has a 
wider furrow, deepened and widened at the top The abdomnal petiole is 
not quite so long as the metanotum and is as long as the basal point of the 
hind tarsi. Temples roundly, obliquely narrowed, the occiput not trans- 
verse. Pronotum two-thirds of the length of the mesonotum, the basal 
two-thirds gradually narrowed.
