MR. A. MURRAY'S MONOGRAPH OF THE FAMILY OF NITIDULARLE. 293 
Oblong, depressed, black, opaque. Antenne rufo-piceous. Head thickly punctate, 
very slightly nigro-pubescent, in front obsoletely bifoveolate, the mouth piceous. Thorax 
a little shorter than broad, very little narrowed in front, thickly punctate, faintly nigro- 
pubescent, flat, with the margin reflexed, densely fringed with short hairs; sides lightly 
rounded, posterior angles right angles. Scutellum (fig. 52) large, subpentagonal, punc- 
tulate, nigro-pubescent. Elytra flat and smooth, a half longer than the thorax, Fig. 52. 
truncate, depressed, lightly striate, with the interstices obsoletely rugulosely KR 
punctate in rows. Abdomen above thickly and lightly punctate, with the ante- 
penultimate segment entirely and the penultimate at the base fulvo-pubescent; fimbrie, 
except on the pygidium, widest behind. Metathorax and ventral segments of abdomen 
griseo-pubescent. Legs piceous; tarsi fulvous. 
From Van Diemen's Land. Not common. 
7. BRACHYPEPLUS CASTANEIPES. 
B. plano valde affinis; minor, angustior, prothoracis lateribus paulo rectioribus, antice 
minus rotundatis ; antennis pedibusque castaneis vel ferrugineo-piceis. Long. 2j lin., 
lat. 4 lin. 
“ Habitat in Australia. 
This is the South-Australian representative of the Tasmanian species, B. planus. It 
is a good deal smaller, and apparently narrower, although, perhaps, the proportions are 
the same. In every detail it tallies very closely with that species, except, perhaps, that 
the sides of the thorax are straighter and less rounded-in in front. The inflexed mar- 
gins of the elytra and the under side of the thorax are ferrugineo-piceous, and the 
antenn: and legs are still lighter, instead of being dark piceous as in B. planus; but 
this variation of colour is a character of small value. 
This will be regarded as a species or a variety according to the predisposition of the 
. reader. 
From Melbourne. 
(Subgenus BRACHYPEPLUS proper.) 
Corpus elongatum, plus minusve depressum et pubescens. "Thorax marginibus haud ciliatis. Ligula lobis 
sat prominentibus. Abdomen segmentis 1mo et 2do brevioribus, pygidio inter fimbrias basi longi- 
tudine latiore. 
Body more or less depressed, elongate, usually pubescent. Mandibles either without a 
tooth behind the point, or with a very small one almost effaced. Labrum transverse, with 
the margin feebly bi-emarginate. Ligula short, with the membranous lobes rather pro- 
minent. Thorax with the sides not fringed with hairs. Scutellum transverse, rounded 
at the apex, pentagonal or quadrangular. Abdomen with the first two segments con- 
siderably shorter than the rest; not rapidly attenuated behind; the breadth of the 
pygidium between the fimbriz at the base greater than its length. 
The non-ciliation of the margins serves to distinguish this subgenus from the subgenera 
Onicotis and Tasmus, the moderate attenuation of the apex of the abdomen from the 
subgenus Selis, its pubescence from .Leiopeplus, and its short first two segments from 
Liparopeplus and Adocima.
