of the posterior. The elytral tubercles appear to be on the 

 third and fifth interstices, the largest being on the third at 

 the summit of the posterior declivity (this part is fully as 

 long as the part preceding it); the tubercles entirely inter- 

 rupt the sequence of the punctures, so that these are seriate 

 in arrangement only on the sides and posteriorly. 



Omydaus subfasciculatus, n. sp. 



Moderately densely clothed with ochreous-brown scales, 

 the elytra with sooty scales subfasciculate in arrangement. 



Head coarsely punctate ; with a narrow median carina ; 

 eyes not very finely faceted. Rostrum inflated near (but not 

 at) base; basal half coarsely punctate, and with a distinct 

 median carina, apical half shining and with small punctures. 

 Scape the length of funicle ; first joint of the latter dis- 

 tinctly longer than second. Prothorax feebly convex, sides 

 very feebly rounded, base bisinuate but apparently widely 

 and rather deeply emarginate ; with a moderately distinct 

 median carina; with dense large and round but somewhat 

 irregular punctures; posterior angles produced beyond the 

 median lobe. Elytra somewhat angular, shoulders produced ; 

 with series of large, deep, oblong punctures, becoming smaller 

 towards sides and much smaller towards apex ; interstices 

 punctate, the alternate ones distinctly raised, except pos- 

 teriorly. Under-surface with large punctures. Second 

 .abdominal segment very decidedly elevated above third. 

 Tibice striated, the anterior strongly trisinuate beneath. 

 Length, 8 mm. ; rostrum, 2 mm. (vix.) ; width, 3 J mm. 



#<z&.— New South Wales: Galston (A. M. Lea). 



In appearance nearer fuliginosus than any here described, 

 but this is in consequence of the raised elytral interstices ; 

 otherwise they are very distinctly separated by the rostrum, 

 abdomen, base of prothorax, tibiae, etc. The rostrum is 

 thinner and less parallel-sided than in any of the others 

 except of the following species. The fascicles on the elytra 

 are confined to the third and fifth interstices except at sum- 

 mit of posterior declivity. In consequence of the subapical 

 tooth of the anterior tibiae being rather large, and the tibiae 

 themselves feebly dentate in the middle, they are strongly 

 trisinuate beneath. 



Omydaus contractus, n. sp. 



Moderately-densely clothed with stoutish scales, varying 

 from a dingy-grey to sooty-black, and subfasciculate on 

 elytra. 



Head rather coarsely punctate ; with a distinct median 

 carina; eyes comparatively coarsely faceted. Rostrum sud-
