182 REVISION OF THE AUSTRALIAN CURCULIONIDiE 



Antennpe setose, not at all squamose or mealy; sette more distinct 

 on prothorax and more numerous and irregular on elytra than in 

 either of the preceding Ciliation short, feeble. 



Head rather small (for the genus), subconvex ; ocular fovea 

 appearing as a shallow transverse impression; densely punctate, 

 the punctures distinct and setose. Basal two-thirds of rostrum 

 punctate as head, apical third with punctures visible to derm. 

 Funicle with 1st joint slightly longer than 2nd, 4th-7th trans- 

 verse. Prothorax scarcely longer than wide, with moderately 

 dense, large, round, shallow punctures, somewhat unevenly dis- 

 tributed and leaving a narrow interrupted median line, each 

 puncture carrying a small seta which does not rise above the 

 general level. Elytra slightly wider than base of prothorax, with 

 nine rows of strongly impressed punctures, the two rows nearest 

 the suture smaller and more distinct than the others; in the other 

 rows they are larger, transverse and contiguous; interstices feebly 

 raised, near suture straight, about the middle zigzag-shaped or 

 appearing as a succession of small v'ss, apex with somewhat 

 irregular punctures. Under surface much as in the two preceding 

 species; mesosternal receptacle a little more noticeably raised 

 and shorter from base to apex. Length 6, rostrum 1|; width 

 2| mm. 



Hab. — JSTorth West Australia : Upper Ord River (Mr. Richard 

 Helms). 



In this species the scales appear almost as if soldered to the 

 derm; in the two preceding the clothing appears to be looser. 



MiCROPOROPTBRUS, n.g. 



Head feebly convex, ocular fovea very small. Eyes small, 

 somewhat prominent, moderately faceted, distant. Rostrmn sub- 

 parallel, moderately elongate, comparatively slender, curved. 

 Scape inserted slightly in advance of middle of rostrum, just 

 reaching or slightly passing apex. Prothorax feebly transverse, 

 ocular lobes feeble, constriction obsolete, base truncate, median 

 line marked. Sciitellum absent. Elytra not or scarcely twice 

 the length of prothorax, wide, shoulders rounded. Pectoral canal
