712 REVISION OF THE AUSTRALIAN CURCULIONIDiE, IX., 



Deretiosus hystricosus, n.sp. 



Densely covered all over (except apical two-thirds of rostrum) 

 with pale fawn-coloured scales, feebly variegated on head and 

 slightly paler on under than on upper surface. Prothorax with 

 six fascicles of which the two in front are distinct, a few elongate 

 stout setse at sides; each elytron with a moderately large (but 

 not very distinct) fasciculate crest on 3rd interstice near base; 

 elsewhere with rather numerous long erect stout setse. 



Narrow, cylindrical, convex. Rostrum slightly curved, sides 

 feebly incurved to middle. Antennae slender; scape slightly 

 shorter than funicle, inserted slightly nearer apex than base; 

 funicle distinctly seven-jointed, Prothorax moderately trans- 

 verse, sides rounded. Scutellum subtriangular. Elytra raised 

 above and about once and one-half the width of prothorax, base 

 trisinuate, shoulders rounded, sides parallel to near apex; stria? 

 not traceable through clothing. Femora subclavate, teeth large 

 and acute. Length 4, rostrum 1; width 1§ mm. 



Hab. — Q.: Cairns. (Type in Macleay Museum). 



Closely resembles the preceding species, but the funicle and 

 club are normal; the elytral crests are much smaller, the scattered 

 erect setse are more numerous, longer, more upright and thinner, 

 and the whole insect is smaller. 



After the above description was drawn up, I received numerous 

 specimens from Mr. Hacker (also from Cairns); and nearly all of 

 these have a somewhat sooty and almost circular patch of scales 

 on the posterior declivity. They mostly have also a small patch 

 of sooty scales on the suture, just behind the scutellum.

9 (?). Densely covered all over (except on rostrum and between 

 front coxae) with leaden-grey scales, paler on under surface than 

 elsewhere; the apical segments of abdomen mottled with brown; 

 elytra with a dark velvety space on each side of scutellum at 

 base, and a small rounded spot of similar scales on 3rd interstice
