character alone will readily distinguish it from all the others; 

 they are almost perfectly circular in outline, but from above 

 appear rather narrowly elliptic, and at the base are more 

 than twice as far apart as at the apex. The scape is almost 

 as long as the funicle and club combined. Both specimens 

 at first appear to be Uniformly covered with muddy-looking 

 scales, but on the Mount Gambier specimen, in certain lights, 

 many of them appear conspicuously golden or golden-red. 



Stenocorynus lepidurus, 11. sp. 



Black, appendages more or less obscurely reddish. 

 Irregularly clothed with more or less muddy-brown scales, 

 on the legs mixed with numerous setae. 



Head with small punctures between eyes ; inter-ocular 

 fovea suboblong and fairly large. Rostrum almost twice as 

 long as wide, with a conspicuous median carina, on each side 

 of which is a deep groove ; sublateral sulci deep and sub- 

 crescentic in form. Scape about as long as four following 

 joints combined; two basal joints of funicle rather long, none 

 of the others transverse. P roth or ax rather lightlv transverse 

 in male, widely so in female, with an irregular transverse 

 subbasal impression; surface irregularly vermiculate ; front 

 margin conspicuously incurved behind each eye, and lightly 

 in middle. Scutellum minute. Elytra not. much wider than 

 prothorax at base, sides dilated to beyond the middle ; with 

 somewhat irregular rows of large, round, deep punctures, a 

 few about base transversely confluent; third interstice rather 

 lightly elevated, sixth still more lightly. Length, 10-13 mm. 



Hah. — Queensland: Coen River (W. D. Dodd and H. 

 Hacker). Type, I. 5627. 



On the pronotum and most of the elytra the clothing is 

 rather sparse, but on the apical slope of the latter it is 

 unusually dense, and this does not appear to be due to 

 abrasion elsewhere, as it is alike on the three specimens before 

 me (two of which were taken in cop. by Mr. Hacker). The 

 eyes are narrower and the elytral punctures much coarser 

 than on any other species of the genus. 



Onesorus conifer, Lea. 

 A specimen from Northern Queensland differs from the 

 type in having the humeral tubercle less conspicuous, but 

 otherwise agrees well with it. 



Onesorus armtpennis, n. sp. 



Reddish-brown, in places almost black. Densely clothed 

 with variegated scales, interspersed with numerous stout and 

 more or less decumbent setae.
