In general appearance fairly close to the preceding species, 

 but shorter, and rostrum distinctly shorter. The combined 

 length of the two basal-joints of funicle scarcely more than 

 one-third the length < 2 °) of scape, instead of more than half, 

 eyes larger and sides of prothorax less rounded. Each of the 

 elytral setae is supported by a small granule, these being very 

 distinct from certain directions. 



Myllocerus tibialis, n. sp. 



Black, appendages in places obscurely diluted with red. 

 Densely clothed with ashen-grey scales. Elytra with numerous 

 stiff, erect setae of moderate length. 



Head moderately convex. Eyes rather large and not 

 very prominent. Rostrum distinctly transverse, sides feebly 

 decreasing in width to apex, median carina distinct, the sub- 

 lateral ones almost concealed, apical plate rather large. 

 Antennae comparatively stout; first joint of funicle slightly 

 longer than second, second distinctly longer than third. 

 Prothorax moderately transverse, sides somewhat rounded in 

 middle, base and apex of almost even width, the latter almost 

 straight; with two somewhat irregular transverse impressions, 

 one near apex, the other near base; with rather coarse 

 punctures. Elytra much wider than prothorax; with 

 rows of rather strong, almost concealed punctures. Pro- 

 sternum with a subcorneal tooth behind coxae. Femora rather 

 strongly and acutely dentate ; tibiae, more noticeably the front 

 pair, with a dentiform swelling about middle. Length, 7 mm. 



Hab. — Queensland: Coen River (W. D. Dodd). Type, 

 I. 2551. 



In general appearance the type is somewhat like a large 

 specimen of rugicollis, but the prothoracic impressions are 

 more conspicuous, the elytral setae are erect and much longer, 

 and the front tibiae are conspicuously armed ; the latter char- 

 acter (which, however, may be confined to the male) renders 

 the species one of the most distinct in the genus. On the 

 under-surface of the head there is a subquadrate, highly- 

 polished space on each side of the gular suture, with oblique 

 ridges (probably used for stridulation) towards the sides. 



Myllocerus griseus, n. sp. 

 Black or blackish, appendages reddish. Rather densely 

 clothed with greyish-white scales, feebly variegated with 

 brownish spots on elytra. Upper-surface with fairly dense, 

 short, subdepressed setae. 



(20) To see the proportions clearly the antennae must be viewed 

 from the sides.
