9 • Differs in having less of the rostrum clothed and 

 two basal segments of abdomen gently convex. 



Hah. — Tasmania: Waratah, in moss (A. M. Lea). 



The U-shaped mesosternal receptacle, with thin walls 

 throughout, is at variance with the genus, but as it is not 

 supported by other characters it was considered better to refer 

 the species to Roptoperus rather than to a new genus. It is 

 the smallest one yet described. On the female there is a 

 feeble pale spot on the middle of each elytron, and a still 

 more feeble medio-lateral one, but on the male these are not 

 traceable. 



KOPTOPERUS PALLIDICORNIS, n. Sp. 



(S . Blackish ; head, rostrum, legs, and under-surface of a 

 more or less dingy-red; antennae almost flavous. Upper- 

 surface with stout setae or scales scattered about, and com- 

 pacted into numerous fascicles. 



Head largely bald; with coarse punctures in front. 

 Kostrum very wide at base, strongly narrowed to, and 

 parallel-sided in front of antennae; basal third with coarse 

 concealed punctures and a feeble median carina, elsewhere 

 shining and with minute punctures. Scape short, inserted 

 much nearer base than apex of rostrum. ProtJiorax about 

 as long as wide, sides strongly rounded, disc rather strongly 

 convex; with dense and coarse punctures. Elytra subcordate, 

 base almost truncate, and narrowly elevated, except at suture 

 and shoulders, sides suddenly and strongly rounded to beyond 

 the middle; with rows of fairly large punctures, in distinct 

 striae; third and fifth interstices with feeble swellings sup- 

 porting fascicles. Basal segment of abdomen distinctly con- 

 cave, with a curved row of large punctures; second segment 

 with large irregular ones in middle, the other segments with 

 small ones. Length, 3 mm. 



Hah. — Queensland: Little Mulgrave River (H. Hacker). 



More of the head is bald than in scutellaris and terrce- 

 regince; the bald space is marked off from the base by an 

 impressed line, but until the head is detached from the body 

 this line is concealed. On the upper-surface most of the derm 

 is visible, but not to the same extent as in longus. The abdo- 

 men of the type is almost entirely glabrous, but this may be 

 due to abrasion. The elytra at the extreme base are no wider 

 than the base of the prothorax, but the sides are strongly 

 rounded, so that at their greatest width they are fully once 

 and one-half as wide. 



RoPTOPERUS terr.j:-regin^, Lea. 



The base of the elytra of this species is narrowly raised 

 and shining (on the type this was concealed by gum). On
