smooth except the metapleuree which are sparsely punctulate. Pro- 
and metapleure thinly clothed with pale hairs. Metathoracic spiracles 
small, elongate oval. Abdomen as long as the head and thorax together; 
its surface shining, impunctate. First segment scarcely widened 
apically, twice as long as broad at tip, the median portion raised and 
carinate laterally at the base; toward each side with a carina separated 
from the median elevation by a broad smooth groove and from the 
extreme lateral edge by a linear furrow. Second segment fused with 
the third, but the suture indicated medially by a broad crenulate furrow; 
anteriorly with a trifoliate elevation consisting of a narrow pointed 
median elevation and lateral ovate elevation; sides of second segment 
separated from the median part by a longitudinal impressed line and 
from the base of the third by an oblique impressed line. Third segment 
with a small lozenge-shaped tubercle medially at the base, on each side 
of which is a large, faintly raised elevation; anterior angles also slightly 
elevated into a rounded convexity. Following segments not sculptured. 
Legs stout, the hind pair considerably thickened; fore tarsi distinctly 
more than twice as long as their tibiz, each of which bears along its 
front side a series of five short, stout fuscous spines or thorns. ‘Tarsal 
claws large, simple, wings with the submedian cell longer than the 
median by one-fifth the length of the basal vein; recurrent nervure 
received at the apical sixth of the first cubital cell; discoidal nervure 
arising at the posterior angle of the second discoidal cell. Submedian 
cell in hind wing more than half the length of the median; radial cell 
divided by a cross-vein. 
One female from Abunda, Rio Madeira, Brazil, Mann and 
Baker. 
This species differs from B. spinicollis Brullé, the only 
species hitherto described, by its entirely red mesonotum, red 
middle coxe, and the much greater amount of black on the 
abdomen. Brullé does not mention the second pair of teeth on 
the margin of the prothoracic pleure, nor the spines on the 
anterior tibie. These may be present in his species, but it 
does not seem possible that he could have overlooked both 
these striking characters. 
Parabinarea Gen. nov. 
Similar to Binarea Brullé, but differing by the presence of three 
spinose tubercles on the pronotum, the absence of tubercles on the 
propleure, the structure of the metathorax, which is covered with flat, 
circular impressions, and the aciculate sculpture of the first two abdom- 
inal segments. 
Head nearly quadrate, strongly rounded off behind and excavated 
on the occiput; with a large shallow impression above the antennz 
which are long slender and many jointed. Pronotum with a pair of 
spinose tubercles near the anterior margin, and with a single median one 
behind. Propleurze convex, not tuberculate. Mesonotum with deep
