734 NEW SPECIKS OF AUSTKALIAN COLEOPTERA, xii., 



POLYPHRADES CORDATUS, ll.sp. 



Black, appendages more or less reddish. Densely clothed 

 with muddy-brown mottled with ashen scales, becoming almost 

 entirely ashen on undersurface; elytra with sparse setae, distinct 

 only on sides and on apical slope. 



Rostrum not very long, sides almost parallel, transversely im- 

 pressed on each side of base; inter-aiitennarv space almost 

 parallel, not conspicuously tricarinate: apical triangle distinct. 

 Antennte not vei-y stout; first joint of funicle as long as second 

 and third combined, second as long as third and fourth combined, 

 third to seventh transverse. Prothorax strongly transverse, 

 sides rather strongly rounded, derm concealed. Elytra con- 

 spicuously cordate, each separately rounded at base, sides strongly 

 rounded; with regular rows of large punctures, appearing much 

 smaller and in narrow strise before abrasion. Claws short and 

 feebly cleft. Length, 3 mm. 



/fa6.— N.S.W.: Forest Reefs (A. M. Lea). 



A very small species, with the elytra more perfectly heart- 

 shaped than in any other species (even including P. cordipennis) 

 before me. Prom the many small species of the genus, readily 

 distinguished by the combination of heart-shaped and incon- 

 spicuously setose elytra, short rostrum (notched on each side of 

 base), and short scape. In general appearance, it comes fairly 

 close to P. marmoratus before abrasion, but the elytra are some- 

 what different at the base, the prothorax and rostrum are nar- 

 rower, and the colour of the derm is different; P. inconspicuus 

 has distinctly longer elytra, rostrum, and antennae. In some 

 lights, a row of setse may be traced on each elytral interstice. 

 No granules are traceable on the prothorax before abrasion; and 

 where the disc has been partly aljraded, a few fairly large punc- 

 tures are in evidence, but no granules. The type appears to be 

 a female. 



POLYPHRADES SUBTERRANEUS, n.Sp. 



(J. Blackish, some parts obscurely diluted with red, append- 

 ages usually entirely reddish. Densely clothed with somewhat 

 variegated scales; mixed with numerous stout, more or less erect 

 seta^;.
