from apex, nearly half of its length passing muzzle (a little less 

 in 2); 1st joint of funicle a little longer than 2nd, 2nd as long as 

 two following combined; club subadnate to funicle. Prothorax 

 very little longer than wide; apex feebly produced; rounded, not 

 much narrower than base; ocular lobes almost obsolete; constric- 

 tion rather feeble, continuous across summit, median carina short 

 but moderately distinct, transverse row of tubercles feeble but 

 more distinct than in either of the preceding, with numerous 

 small granules. Sciitellum very small. Elytra feebly bisinuate 

 at base, where it is as wide as prothorax, and more than twice as 

 long; sides feebly widening to about the middle, towards apex 

 curved inward, apex itself almost truncate, thickened and feebly 

 flattened; with distinct but somewhat irregular rows of moderately 

 large punctures; 2nd and 4th interstices ver}^ feebl)^ tuberculate, 

 the tubercles moderately distinct when viewed sideways, one on 

 each side of summit of declivity (which is more elongate than in 

 either of the preceding) is a little more distinct. Abdomen very 

 feebly convex, basal segment not twice as long as 2nd, from the 

 2nd feebly encroached upon by sides of elytra in ^; intermediates 

 rather large, longer than 2nd or apical, apical feebly transversely 

 impressed in ^. Femora in both sexes slightly passing inter- 

 mediate segments; tibiae very feebly curved; tarsi short, 3rd joint 

 rather widely bilobed, 4th a little longer than 1st. Length 10,

Hab. — Tasmania (Mr. A. Simson, No. 3203; Rev. T. Blackburn,

I have a specimen in which there are two small triangular 

 patches of whitish scales on each side of the suture at base. 



Group B. — Type P. succisus. 



Narrow, subelliptic, convex, tuberculate and granulate. Ros- 

 trum curved, sparsely squamose. Antennae elongate ; scape 

 inserted at about one-third or less from apex, moderately or con- 

 siderably passing muzzle; 1st joint of funicle equal to or a little 

 longer than 2nd; club free. Prothorax carinate, apex scarcely 

 narrower than base. Scutellum very small. Elytra widest about
