458 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES^ 



length. The surface of the prothorax is said to be " covered with 

 fine rugosities hardly distinct under a lens "; although this appears 

 to be the case in a fresh specimen owing to the presence of pubes- 

 cence I find that the removal of the pubescence exposes a surface 

 very distinctly, although finely, rugulose-punctulate. 



DiAPHANOPS Meyricki^ sp.nov. 



Oblongus, postice angustatus ; rufo-brunneus, pilis densis (supra 

 pallide briinneis, subtus albidis) tectus ; palpis nigris ; prothorace 

 quam basi latiori quinta parte longiori ; elytris utrinque oblique 

 impressis ; antennis corporis dimidio sat brevioribus.

The entire insect (except the palpi) is of a uniform pale reddish 

 brown colour densely clothed with silky pubescence on every part 

 except the antennae, which however are quite concolorous with the 

 general surface. The pubescence is of the ground colour on the 

 upper surface except the scutellum, which together with the under- 

 side is silvery white. The whole upper and under surface is finely 

 and very closely punctulate, but the sculpture is entirely hidden 

 beneath the pubescence. The sides of the prothorax are gently 

 concave from the base to beyond the middle where the segment is 

 nearly as wide as at the base and whence they converge slightly to 

 the apex; a longitudinal median carina is feebly indicated on the 

 hinder half of the dorsal surface. The elytra across the base are 

 twice as wide as the base of the prothorax and are evenly and 

 rather strongly narrowed to their apex ; the oblique impression on 

 either side is quite distinct but not sharply limited, commencing 

 near the lateral margin a little behind the shoulder and terminating 

 about the middle of the disc half-way ,to the apex ; the elytra are 

 obliquely truncate behind. The antennae are of the length of the 

 prothorax and head (including the rostrum) together. Inter alia 

 the shorter antennae, of a unicolorous bright pale brown, appear to 

 distinguish the species from D. Westermanni. 



Three specimens, quite identical inter se, were sent to me from 

 Western Australia by E. Meyrick, Esq.
