This is a giant in the genus Opsomala, being nearly twice as long as the largest described
species. It is entirely of a luteous brown colour slightly varied with darker brown, with a paler
oblong patch on each side of the upper surface of the prothorax. The head is produced into
a rostrum nearly three-fourths of an inch long, its upper being nearly continuous with
the disk of the head, and gradually narrowed from the eyes to the tip ; the upper surface flat
along the middle, but with the sides towards the eyes deflexed ; the under surface of the
rostrum forms a very sharp edge, and is slightly curved, the tip being obliquely truncate.
The eyes are oval and slightly elevated ; the antennae are placed at the base of the lateral
channel which extends from the base to the apex at the sides of the rostrum ; they are slender,
filiform, and not so long as the rostrum. The prothorax is slightly rugose, with the dorsal
carina scarcely elevated, and with three transverse very slight impressed lines across the middle
of the back. The tegmina are narrow, not so long as the abdomen, with the apex almost
rounded ; they are of a pale luteous-brown colour, with the veins varied with darker brown ;
the wings are almost colourless ; the middle of many of the cells is, however, rather clouded
with a tinge of pale brown. The abdomen is very compressed and shining, with the anal ap-
pendages whitish. The four fore legs are very short, and the hind pair are scarcely longer
than the abdomen ; the femora terminating on the outside in an elongated spine. The pro-
sternum is armed with a short spine, and the meso- and metasternums are broad.
