it differs in being more cylindrical, prothorax less transverse, 

 medio-apical incurvature less pronounced, and rostrum of 

 somewhat different shape. Very close to incurvus, but with 

 second joint of funicle less noticeably shorter than first, pro- 

 thorax slightly more transverse, eyes rather more prominent 

 and form rather less cylindrical. These differences, although 

 only comparative, are quite distinct when specimens of each 

 are placed side by side; but as the two species are separated 

 the width of the continent no confusion will probably arise 

 from correctly labelled specimens. On the prothorax of the 

 four typical specimens the scales are sparser in the middle 

 than elsewhere, but this appears to be due to partial abrasion ; 

 it is certainly of a different nature to the glabrous space on 

 bo villi. 



Myllocerus tristis, n. sp. 



Black or blackish, appendages not much paler. Densely 

 clothed with whitish-grey scales, on the elytra variegated with 

 small feeble brownish spots. 



Head gently convex between eyes; these moderately 

 prominent. Rostrum shorter than wide, median carina 

 feeble, the sublateral ones still more so, apical plate concave. 

 Antennae moderately long; first joint of funicle distinctly 

 longer than second. Prothorax almost thrice as wide as the 

 median length, apex rather strongly incurved to middle, sides 

 increasing in width to base, which is strongly bisinuate and 

 scarcely narrower than elytra, outlines continuous with those 

 of head and elytra; punctures traceable through clothing. 

 Elytra with regular rows of rather large punctures, appear- 

 ing like fine striae through clothing. Legs rather stout; 

 femora edentate. Length, 6-6 J mm. 



Hab. — Queensland: Charters Towers (Blackburn's col- 

 lection). Type, I. 2541. 



Somewhat like small specimens of latibasis, but base of 

 prothorax not wider than elytra. The head is considerably 

 wider and rostrum of different shape to those of the two 

 preceding species. The elytra appear to be without setae, 

 except for a few about the apex. In certain lights many of 

 the scales appear to have a faint golden gloss, but in most 

 lights they appear to be opaque. Two specimens from 

 Charters Towers are alike in colour, but one labelled as from 

 Northern Queensland has no elytral spots. 



Myllocerus prosternalis, n. sp. 

 Black, appendages dull reddish-brown. Densely clothed 

 with greyish-green or coppery-green scales. Elytra with 

 indistinct setae not elevated above scales.
