antercoxal process than elsewhere ; 2nd not as long as inter- 

 mediates combined, with rather sparse shallow punctures; inter- 

 mediates with almost obsolete punctures ; apical segment 

 moderately densely punctate, a shallow depression near its apex. 

 Legs denaely punctate, punctui'es small; femora distinctly dentate, 

 each with a smaller tooth or granule in emargination ; posterior 

 almost extending to apex ot" abdomen; tibite rather feebly grooved, 

 moderately curved at base ; claw-joint feebly pubescent, claws 

 moderately separated. Length 6§, rostrum 2^; width 3^ mm. 



Rab. — N.W. Australia (Mr. G. Masters) — N.Q. : Somerset 

 (Mr. C. French). 



Somewhat resembling the preceding species, but — besides the 

 more noticeable differences of rostrum, antennae, abdomen and 

 pectoral canal — differs in being somewhat more bulky, with less 

 trigonal elytra, larger scutellum, more obtuse ocular lobes, stouter 

 femora and more regular elytral interstices. The granule in the 

 femoral emargination occurs (so far as I am aware) only in this 

 and the preceding species. 



Melaxterius porosus, n.sp. 



Elliptic, shining, convex. Black ; tibipe, tarsi, rostrum and 

 antennae dull red. Punctures of prothorax, under surface and 

 lesrs each with a minute hair. 



Head densely punctate; eyes large, rather widely separated, 

 coarsely faceted. Rostrum long, parallel, curved; densely punc- 

 tate, punctures decreasing in size to apex; not carinate. Scape 

 inserted about one-third from apex of rostrum, about half its 

 length passing apex; 1st joint of funicle moderately long, 3rd-7th 

 short; club briefly ovate. Prothorax scarcely transverse, rounded, 

 base very feebly bisinuate, posterior angles almost right angles; 

 densely, shallowly and very regularly punctate ; median line 

 almost invisible ; ocular lobes very feeble. Scutellum small, 

 oblong. Elytra not much wider than prothorax and more than 

 twice its length, widest about one-third its length from base ; 

 each with ten rows of deep, narrow, oblong punctures, connected 

 together by almost invisible grooves ; interstices on basal half
