Melanterius cordipennis, n.sp. 



(J. Elliptic, convex, polished. Reddish-castaneous, head, 

 rostrum and legs darker than prothorax and elytra. Upper 

 surface with almost microscopic setse ; under surface and legs 

 sparsely clothed with whitish seta?. 



Head densely punctate, punctures small and shallow ; not 

 depressed between eyes ; eyes very large, subreniform, almost 

 touching above. Rostrum moderately long, comparatively stout, 

 curved, feebly dilated between antennae; rather coarsely punctate, 

 punctures strongly confluent and leaving five feeble ridges 

 exposed behind the antennse. Scape rather stout, inserted two- 

 fifths from apex of rostrum, decidedly shorter than funicle. 

 Prothorax feebly transverse, apex about two-thirds the width of 

 base ; base bisinuate ; densely punctate, punctures of moderate 

 size but very sharply defined and nowhere confluent. Scutellum 

 suboblong. Elytra cordate, once and one-third as wide and twice 

 as long as prothorax, shoulders rounded; seriate-punctate, punc- 

 tures rather large, suboblong, open at both ends ; interstices 

 triangularly raised except at base. Metasternum and two basal 

 segments of abdomen with large punctures; intermediates each 

 with a feeble row of punctures, their combined length slightly 

 more than that of 2nd or 5th. Femora stout, acutely dentate ; 

 tibijfi seriately punctate. Length 3|, rostrum 1-J-; width If mm. 



Ilab. — Q. : Endeavour River (Macleay Museum). 



A very distinct species. The elj'tral punctures are large, but 

 being shelving at both ends appear to be smaller than they 

 actually are; the clothing of the upper surface is so minute that 

 it is only traceable with difiiculty. 



Melanterius unidbntatus, n.sp. 



^ (?). Ovate, somewhat depressed, shining. Black; antennae 

 dull red. Prothoracic punctures each with a very small and 

 scarcely traceable seta ; elytra scarcely visibly clothed. Under 

 surface and legs with moderately elongate whitish setaj. 



Head^f ith. dense but small and shallow punctures; eyes large, sub- 

 reniform, separated for almost the entire width of rostrum at base.
