 Elytra oval (12x5-5 mm.), convex; base deeply (not abruptly) 

 declivous; shoulders rounded; lateral border lightly folded back 

 (not prominent or upturned) at humeral angles; a row of ocellate 

 jjunctures ii:i^ lateral channel; six or seven punctures in a double 

 row on basal declivity. Prosternum sparsely setigerous-punctate 

 on each side before coxte. Yentral segments with punctures of 

 ambulatorial setae present, suture between second and third 

 segments obsolete in middle. Legs long, light; anterior femora

 Hah. — West Australia (Coll. French). 



This species has no near affinity to any Carenid known to me, 

 but evidently is congeneric with Trichocarenum elderi., Blkb. 

 Judging from the description of T. elderi, T. cylindricum differs 

 from it in the supraorbital punctures, the punctures of the lower 

 side of the anterior femora, in having one (not two) rows of 

 punctures besides those of the marginal channel on each elytron, 

 and in the absence of the closely placed punctui^es of the lateral 

 channel of the prothorax. 



Neocarenum spenceri, n.sp. 



Lsevigate, robust, elongate, dorsal surface rather depressed; 

 head large, obliquely and decidedly narrowed behind eyes; pro- 

 thorax as long as wide, base wide (5 mm.) ; elytra impunctate, 

 deeply retuse at base, humeral angles very pi'ominent, inflexed 

 margin narrow behind first ventral segment ; anterior tibiae 

 bidentate, intermediate tibiae with a long jDrominent external 

 spur at apex. Black, shining; prothorax and elj'tra with narrow 

 cyaneous margin. 



Head large (5x6-5 mm.); occipital region depressed below 

 plane of vertex; frontal sulci deep, posterior part of their course
