A stout keel runs from near the centre of the front to the inner side 
of the antennae. There is a triangular and a shorter rounded tooth on 
either side of the centre of the clypeus ; the third joint of the antennae 
is almost as long as the following two united ; pronotum longer than it 
is wide at the apex, which becomes gradually raised in the middle into a 
bluntly rounded point ; the sides are bluntly margined ; the central keel 
on the metanotum runs to the base of the apical fourth ; the second con- 
verges roundly towards the apex ; the third and fourth are united at the 
base ; there is an irregular reticulated part at the apex of the first keel ; 
the rest of the metanotum is closely, transversely striated ; the apical 
slope is irregularly reticulated, the sides at the top projecting into stout, 
triangular teeth ; the upper part of the metapleurae is stoutly, irregularly, 
obliquely reticulated, the reticulated band gradually widened towards 
the apex ; the rest is smooth ; the first abdominal segment has a distinct, 
twice wider than long, petiole ; the second is of the same width at the base 
as it is at the apex, and has the sides rounded ; claws dilated to shortly 
beyond the middle, the apex narrowed, curved ; tarsi closely, strongly 
spinose ; spurs dark- testaceous ; on the depressed base of the pronotum 
are two stout, rounded keels ; the silvery pubescence is dense on apex 
of pronotum, post-scutellum, apex of mesopleurae and of metapleurae, 
and the apical abdominal segments ; the hair on the head, thorax, and 
legs is long and white.

Black ; the apex and centre of clypeus, mandibles, the antennae and 
tarsi, rufo-testaceous ; the apical joints of the antennae darker-coloured 
than the others ; wings hyaline ; the nervures and stigma black ; a fuscous 
cloud behind the submedian nervure, and a narrower one, narrowed in 
front, behind the posterior part of the transverse basal, one filling the 
radial cellule, one, obliquely narrowed behind, beyond the middle of the 
first cubital cellule, one almost filling the second, and a semicircular one 
in front of the second recurrent along its anterior three-fourths ; tegulae 
fuscous ; the head, thorax, and legs covered with white down. Female. 
Length, 6 mm. 
Head opaque, finely, closely punctured, the inner orbits with a narrow, 
irregularly stiiated band ; hind ocelli separated from each other by half 
the distance they are from the eyes ; pronotum alutaceous, the depressed 
sides thickly covered with depressed silvery pubescence ; the centre from 
the teeth furrowed, and bearing large, round, clearly separated punctures ; 
the apex transverse, furrowed ; the centre of mesonotum with a large, 
strongly punctured band, nearer the base than the apex ; the furrows 
are complete ; metanotum irregularly, transversely striated, with a 
central and three lateral longitudinal keels ; the central straight, the
