The head (fig. 1 a, seen from the front) is very rugose ; the £' :e with two slight curved carina; extending
from the anterior margin of the clypeus to the lower part of the eye .; the face has the lateral margins slightly
raised, with three eonieal tubercles on each side, a small tubercult ed ridge also extends across the forehead
between the tops of the eyes. The antennse are irregularly curved the ninth joint is not thicker, but rather
longer than the preceding, oblique at its tip, and the tenth joint is very small. The thorax is punctured, the
dorsum of the mesonotum tricarinated. The basal segment of the abdomen has two transverse, slightly curved
series of very short deeply impressed lines at its base, followed by a narrow, transverse, polished space, with
a small dull black dot on each side ; and the broad terminal margin . f the segment is very rugosely punctured.
The six terminal segments of tlie abdomen are much more delicati ly punctured. The legs are a3neous, the
anterior tibia; have a strong notch on the under side near the tip ( ig; 1 d), and the tarsi are set on obUquely;
the posterior tibia; are subserrated on their outer margin. The wings are dark brown, with a slight purplish

This s])eoies, in several respects, so closely resembles 0. Bateúanus (inhabiting also the same locality on the
Amazon Eiver) that it may possibly ultimately prove to be a variety thereof; the colour, however, of the body,
and especially of the mngs and stigma, seem to indicate it as specifically distinct. The face has two curved
raised lines extending from the lower edge of the eyes towards the middle of the face, where they are united by
a slender transverse carina, behind which are two rows of tubercles. The thorax is black, with a slender central
slightly raised, and polished longitudinal line. The basal segment of the abdomen has a fine row of short
striola; at the base, the remainder being strongly punctured with a central raised line; the third, fourth, and
fifth segments are marked on each side with a small whitish spot. The legs are thick and black, the two
posterior femora red, the hind tibia; externally serrated. The fore wings have a broad fascia before, and another
beyond the middle, the base being hyaline with two small oblong dark dots; the veins in the central hyaline
part of the wing are colourless, and the stigma is fulvous.
