Head moderately convex; eyes scarcely interrupting 

 general convexity of outline. Rostrum stout, scarcely as long 

 as the basal width ; sides feebly decreasing in width to near 

 apex ; median carina narrow and distinct, the sublateral ones 

 less so. Antennae rather thin; first joint of funicle slightly 

 longer than second, second as long as third and fourth com- 

 bined. Pro thorax almost twice as wide as long, sides feebly 

 rounded, apex feebly incurved to middle and about the width 

 of base ; punctures normally traceable. Elytra distinctly 

 wider than prothorax, sides very feebly dilated to beyond 

 the middle; with rows of rather large punctures, appearing 

 small through clothing. Femora scarcely visibly dentate. 

 Length, 5-6 mm. 



Hab. — North-western Australia (Blackburn's collec- 

 tion). Type, I. 2552. 



The eyes, although fairly large, are much less prominent 

 than is usual. In general appearance the species is close to 

 amblyrhinus, but the prothorax is slightly wider at the base 

 than at the apex. Nasutas has the prothorax less transverse, 

 quite straight at apex, and much more prominent eyes. 

 Bceodontomerus has head and rostrum narrower, and pro- 

 thorax much less conspicuously transverse. Sordidus has the 

 prothorax less transverse, and with more strongly rounded 

 sides. 



Myllocerus melvillensis, n. sp. 



Of a rather pale red, club darker. Densely clothed with 

 greyish-white scales, mottled with pale-brown. 



Head rather convex. Eyes rather small, widely separated, 

 very prominent, and decidedly closer to prothorax than usual. 

 Kostrum stout, slightly shorter than the basal width, sides 

 gently incurved; carinas rather feeble. Antennae thin; first 

 joint of funicle slightly longer than second. Prothorax not 

 quite twice as wide as long, sides feebly bisinuate, apex 

 straight and as wide as base, a vague transverse impression 

 near apex and another near base; punctures scarcely 

 traceable. Elytra much wider than prothorax, feebly dilated 

 to beyond the middle ; punctures appearing small through 

 clothing. Femora edentate. Length, 4 mm. 



Hab. — Northern Territory: Melville Island (W. D. 

 Dodd). Type, I. 2553. 



Allied to riir/icollis, but prothorax wider, more con- 

 spicuously bisinuate at base, head more convex between eyes, 

 and these more rounded and prominent. In the present 

 species the base of each elytron is rather distinctly produced 

 half-way between the suture and side ; in riigicollis this is not 

 the case. The head and elytra are feebly mottled with 

 irregular brown spots ; on the prothorax there is a fairly wide
