with dense, rouud, concealed punctures. Elytra about one- 

 third wider than prothorax, base trisinuate, parallel-sided to 

 beyond the middle, with rows of large concealed punctures; 

 but striation traceable through clothing. Under -surf ace with 

 dense concealed punctures. Basal segment of abdomen flat 

 in middle. Length, 6 mm. 



Hah. — North Queensland (Blackburn's collection). 

 Type, I. 1536. 



The largest of the genus. The tarsi are moderately 

 densely setose on the upper-surface, the setae extending to the 

 claw joint, the third is wide and deeply bilobed, but these 

 characters are not sufficiently important to exclude it from 

 Achopera. The scales are of an almost uniform colour 

 throughout; although on each shoulder there is a large patch 

 where they are somewhat paler than elsewhere. Except on 

 antennae, tarsi, and parts of the rostrum they everywhere 

 conceal the derm. But on the prothorax they are larger 

 than elsewhere, and give it a plated appearance; each also 

 is slightly depressed at its middle. On the abdomen also the 

 scales have a somewhat plated appearance, although they are 

 smaller and more overlapping than on the prothorax. The 

 sex of the type is doubtful. 



Achopera sabulosa, Lea. 

 A male from Port Lincoln differs from the types in 

 having the large scales on the prothorax and elytra somewhat 

 wider; but I can find no other differences. 



Deretiosus zopherus, n. sp. 



Dark reddish-brown, in parts almost black; antennae 

 reddish. Very densely clothed with muddy-brown scales. 

 With numerous stout suberect scales interspersed, and in 

 places compacted into fascicles. 



Head with punctures entirely concealed. Rostrum rather 

 long, moderately curved, sides lightly incurved to middle; 

 punctures concealed behind antennae, but crowded in front. 

 Antennae thin, inserted about one-third from apex of 

 rostrum. Prothorax moderately transverse, surface somewhat 

 uneven; with crowded concealed punctures. Elytra parallel- 

 sided to beyond the middle; with rows of large, round, 

 almost-concealed punctures ; third interstice with an 

 elongated granulated tubercle near base, and a slight swelling 

 beyond the middle. Punctures of under-surface concealed. 

 Femora strongly triangularly dentate; tibiae bisinuate on 

 lower-surface. Length, 5 mm.
