Head with concealed punctures. Eyes rather small. Ros- 

 trum moderately long, feebly curved, very feebly dilated from 

 base to apex; basal half with concealed sculpture, elsewhere 

 shining and with minute punctures. Scape inserted about 

 one-third from base of rostrum. Prothorax about as long as 

 wide, moderately convex, sides somewhat rounded ; with 

 dense, round, concealed punctures. Elytra about one-third 

 wider than prothorax, sides almost parallel to beyond the 

 middle; with rows of large, almost, or quite, concealed punc- 

 tures. Metasternum distinctly longer than the following seg- 

 ment; the latter flat in middle. Claw- joint unusually long. 

 Length, 2 mm. 



Hah. — Queensland: Cairns district (A. M. Lea). Type, 

 L 1535. 



In the table of genera allied to Chcetectetorns'^'^^^ would be 

 associated with Menios, from which it is at once distinguished 

 by the edentate femora. The prothorax is less depressed than 

 is usual in Achopera, but as that appears to be the only dis- 

 crepancy it was referred to that genus. It is the smallest of 

 the genus, and, except for some minute species of Ephrycus, 

 the smallest of all the Australian members of the Chcetecte- 

 torus group. The sex of the type is doubtful, the rostrum and 

 insertion of antennae appear to denote that it is a female, but 

 the basal segment of abdomen is quite flat in the middle. The 

 antennae are almost flavous. On the upper-surface there are 

 two small sooty spots at the base of the prothorax, several at 

 base of elytra, a series across summit of posterior declivity, and 

 a few below same; but they are all rather ill-defined. On the 

 legs also there are some obscure sooty patches. 



ACHOPERA ISABELLINA, n. Sp. 



Dark reddish-brown, in parts almost black; antennae and 

 tarsi reddish. Densely clothed with more or less greyish or 

 light-brown scales. With moderately stout, subdepressed 

 scales, more or less regularly distributed, and forming a 

 regular row on each elytral interstice. 



Head rather convex ; with very dense concealed 

 punctures. Rostrum comparatively long, and rather thin, 

 moderately curved, parallel-sided except for a slight increase 

 in width near base ; basal third with concealed sculpture, 

 elsewhere somewhat shining, and with dense clearly-defined 

 but rather small punctures. Scape inserted slightly nearer 

 base than apex of rostrum, half the length of funicle and 

 club combined. Prothorax rather lightly transverse, some- 

 what convex, sides strongly rounded, base strongly bisinuate;
