SO Mr. W. E. Shuckard’s Descriptions 
Atrous ; densely clothed with a silvery pubescence, especially 
the face, cheeks, collar, sides of the thorax, sternum, metathorax, 
and legs, and the sides and margins of the segments of the ab- 
domen. The metathorax with the central carina distinct, laterally 
obliquely striated ; the striae far apart, and the interstices punc- 
tured. The tegulae testaceous. The wings hyaline, their apex 
somewhat obscure, arid the nervures black ; the legs unarmed. 
The abdomen having the constrictions of the three first segments 
very conspicuous. $ .

Obs. — The chief character of this elegant little insect, namely, 
its silvery clothing, is evanescent, as it would exhibit this only in a 
fine condition ; but the sculpture of its metathorax, combined with 
the peculiar neuration of its wings, afford sufficient positive cha- 
racters to separate it from its yet known congeners. It is unique 
in Mr. Westwood’s Collection. This genus, as I have above re- 
marked, appears very widely distributed, even more so than Ta- 
chyies, the metropolis of which is either Africa or India, whereas, 
most probably, that of the genus before us is New Holland and its 
dependant islands.

Length 5| lines. 
Entirely black and shining ; the antennae slightly increasing to- 
wards the apex, and a little longer than the head ; the scape, be- 
neath at its apex having a minute yellow dot ; labrum piceous, cili- 
ated externally ; the mandibles rufo-piceous in the middle. 
The thorax having the collar on each side marked with a short 
and slight sericeous line : the metathorax very gibbous ; the tri- 
angle at its base with a central furrow produced by two longitudinal 
carinae, and laterally and posteriorly rufous. The wings dark at 
the base as far as the commencement of the marginal and second 
submarginal cells, beyond which they are hyaline ; the nervures 
black ; the tibiae and tarsi shining and spinose, the anterior pair 
of the latter strongly ciliated. 
The abdomen with the first segment prolonged anteriorly into a 
petiole ; the margins of the second, third, and fourth segments with
