356 Mr. G. C. Champion on the Tenebrionide 
Cestrinus punctatissimus. 
Cestrinus punctatissimus, Pasc., Ann. and Mam Nat. 
Hist. (4), iii., p. 278. 
Hab. 'Tasmania—Hobart. 
One example. 
Cestrinus brevis, sp. n. 
?. Oblong ovate, moderately convex, opaque, pitchy-black ; the 
upper surface thickly clothed with rather coarse appressed brown 
hairs, amongst which are scattered. yellowish-cinereous hairs ; the 
antenne ferruginous ; the legs fusco-ferruginous, the tarsi ferru- 
ginous. Head short, deeply sunk into the prothorax, densely, 
rugosely punctured, the antennary orbits extending about half- 
way across the eyes ; the epistoma short and limited behind by a 
deep transverse groove, feebly arcuate-emarginate in front ; an- 
tenn about reaching the base of the prothorax ; prothorax trans- 
verse, arcuate-emarginate in front, truncate at the base, widest at 
the middle, the sides obliquely converging thence to the apex, and 
sinuously converging behind, the hind angles rectangular, the 
anterior angles sharp and prominent, the surface coarsely, rugosely 
punctured, the interstices very densely, minutely punctate ; elytra 
a little wider than, and about two-and-a-half times the length of, the 
prothorax, with rows of rather fine, deep, subapproximate punctures 
placed in shallow grooves, the interstices feebly raised, very densely 
minutely punctured, and with fine scattered granules; anterior 
tibize slightly curved inwards, rather slender, the outer apical angle 
obtuse ; anterior tarsi simple. . Length 64, breadth 22 mm. 
Hab. W. Australia—Fremantle and Darlington. 
Two specimens, apparently both females. Less elon- 
gate than C. trivialis, Hr.; the head much shorter, the 
epistoma especially ; the thorax more transverse, and more 
narrowed in front and behind; the seriate punctures on > 
the elytra less coarse, the interstices more sparsely and 
more finely granulated; the pubescence of the upper 
surface not unicolorous. C. brevis is less elongate than 
any of the other species of the genus known to me. I 
have received a specimen of a closely-allied undescribed 
form from the Rey. T. Blackburn.
