distinct basal fovese. Elytra rather more than three times the 
length of, and a little wider than, the prothorax, oblong-oval, 
widest about the middle ; with regular rows of fine punctures placed 
in almost obsolete striae ; the interstices flat ,and each with a row 
of precisely similar punctures, the first (or sutural) interstice more 
thickly punctured towards the base. Posterior femora sulcate 
beneath. 
, $ . Anterior tibiae armed on the inner side about the middle 
with a small triangular tooth ; posterior tibiae broadly and un- 
equally dilated, bisinuate on their upper and lower edges, with a 
broad and deep oblique groove extending across their inner face, the 
concavity smooth within ; posterior femora sparsely ciliate along 
their lower edge. 
Length 4, breadth If mm. (^).

One specimen of this extraordinary little Cistelid has 
been sent by Mr. Walker to the British Museum. The 
broadly dilated hind tibiae have the appearance of being 
twisted^ and are deeply obliquely excavated on their 
inner face. The third joint of the four front tarsi is 
more feebly lamellate beneath than in the two other 
species here referred to the same genus. Notwith- 
standing its hairy clothing and somewhat different 
facies, I hesitate to treat it as generically distinct 
therefrom. Under bark (Walker).

Maxillary palpi stout, the apical joint rather small, sub- 
triangular ; mandibles feebly cleft at the tip ; antennae long 
and stout in both sexes, the joints obconic, 3 and 4 equal in 
length, the others gradually becoming more elongate, 8-11 sub- 
equal ; head short, convex ; the eyes rather small, coarsely granu- 
lated, deeply emarginate, widely separated in both sexes ; pro- 
thorax subcordate, truncate at the base and apex, with shallow 
basal foveae, the lateral carina almost obsolete and placed far 
beneath the margin as seen from above ; scutellum subtrian- 
gular, small ; elytra much wider than the prothorax, parallel to 
beyond the middle, moderately elongate, convex ; legs stout, 
rather short, abnormal in the male; tarsi with the penultimate 
joint feebly lamellate beneath ; claws pectinate ; body narrow, 
parallel, convex, pubescent, winged. 
The above characters are taken from a single species 
from N. Australia. It has a very different facies from
