 tarsal joint very little wider than second and very feebly 

 bilobed. Length, 11-12 mm. 



JlaJ). — Queensland: Cairns (Macleay Musenm). 



Belongs to the e.ritiosus group. From eritiosus itself it 

 is distinguished by the greater number of its elytral tubercles, 

 especially in the subsutural row ; the rostrum also is shorter 

 in both sexes. From rarlahilis it differs in having no tuber- 

 cles at tip of elytra and the others somewhat dif- 

 ferently disposed; for instance, there are not four forming a 

 transverse row just below svimmit of posterior declivity. 



On the prothorax the derm is quite concealed in fresh 

 specimens, apparently by a muddy kind of indumentum ; 

 amongst which stout scales are thickly placed : these also form 

 four small but moderately distinct fascicles across middle 

 (with traces of a second series close to them). The apex itself 

 (which appears to be feebly bifurcated) can scarcely be re- 

 garded as fasciculate, although there are rather numerous 

 scales there. On the elytra the scales are irregularly dis- 

 tribiited, and, although rather more numerous on the 

 tubercles than elsewhere, could scarcely be regarded as form- 

 ing fascicles. On the under surface and legs the scales are 

 more elongate than elsewhere, but they are also mixed with 

 the indumentum. On the head and rostrum the scales are 

 rather short and stout. The hind angles of the prothorax 

 are obtusely rounded, and jDartially concealed by the pro- 

 jecting shoulders. 



POEOPTEKUS CARTNICOLLIS, n. Sp. 



Black ; antennas and tarsi feebly diluted with red. 

 Densely clothed with more or less reddish-brown scales and 

 forming fascicles on the tubercles : in addition the derm is 

 almost everywhere covered with a miiddy-red kind of indu- 

 mentum. 



Head with the interocular fovea very distinct. Rostrum 

 stout, sides rather strongly incurved to middle ; densely and 

 coarsely punctate, punctures more or less concealed on basal 

 half. Antennge stout, inserted almost in middle of rostrum ; 

 scape not jDassing apex ; first joint of funicle stouter and dis- 

 tinctly shorter than second, second almost as long as three 

 following combined, seventh apparently belonging to club. 

 Prothora.T strongly convex, slightly longer than wide, base 

 wider than apex ; deeply constricted near apex, the constric- 

 tion interrupted by a strong median carina, which is con- 

 tinuous from ajDex to base, and overhangs the position of 

 the scutellum ; sides vermiculately impressed ; with six 

 tubercles, a feeble one on each side of apex, and four rather 

 large ones across middle, of these the outer ones are more
