734 NEW SPEClKS OF AUSTRALIAN COLEOPTERA, xiv , 



tures, and a feeble median carina. Elytra parallel-sided to about 

 the middle, thence gently decreasing in width to apex; densely 

 granulate-punctate throughout, l)ut more densely about base 

 than elsewhere; striation well-defined throughout. Metasterninn 

 with a rather wide, shining, median line, lightly impressed along 

 its middle. Tip of abdomen rather densely granulate-punctate. 

 Length, 5 mm. 



Hah. — N.S.W.: Sydney (A. M. Lea); unique. 

 From some directions, the pubescence of the elytra appears to 

 be as dark as that of the prothorax, but, from others, most of it 

 is seen to Vje paler: the front, produced portion of each of the 

 fifth-eighth joints of antennae is not much shorter than the 

 joint itself. 



Arisocephalus rufipennis, n.sp. 

 Black; extreme apex and base of prothorax, elytra, abdomen 

 (in places feebly infuscated), legs (hind coxae and femora ex- 

 cepted), and antennae red or reddish. Densely clothed with 

 short pubescence. 



Head with crowded and rather small punctures; with a con- 

 spicuous median carina traceable to near base, but not on to 

 clypeus; antennary sockets each with a narrow margining carina 

 from eye to side at apex of clypeus. Antennae moderately long, 

 second joint distinctly longer than third, and almost as long as 

 fourth, fourth-tenth equal in length, but fourth-seventh wider 

 and more strongly serrated than the ninth and tenth, eleventh 

 almost as long as the ninth and tenth combined. Prothorax 

 slightly more transverse, but otherwise much as in preceding 

 species. Elytra parallel-sided to beyond middle, with dense 

 punctures about base, becoming less crowded (but quite sharply 

 defined) elsewhere; striation lightly impressed and, in places, 

 scarcely traceable. Length, 5 mm. 



Hah. — Tasmania: Southport (John O. Dawson); unique. 

 In general appearance close to the preceding species, but elytra 

 more brightly coloured, and with different punctures and striae, 

 second and third joints of antennae difierently proportioned, the 

 following ones much less conspicuously serrated, and the median 

 line on the metasternum less conspicuous. The clothing on the
