The following tabulation of the species of Neocarenum may be 

 useful : — 



I. Elytra with a subrnarginal row of piuictures. 



A. Posterior extremities of frontal sulci inturned* X. elongaHan, Macl. 

 B. Posterior extremities of frontal sulci diverg- 

 ing continuously to posterior extremities N. angufifatum, SI. 



II. Elytra impunctate. 



C. Intermeiliate tibia; unidentate externally. 



D. Head small, depressed ; prothorax 



transverse; elytra truncate at base N. xiarckejjx,^ ^\. 



E. Head largp, convex ; prothorax of 



equal length and breadth ; elytra 



deeply retuse at base N. spenceri, SI.

Carenidium leai, n.sp. 



Elongate, depressed, laevigate; lal^rum deeply eraarginate; pro- 

 thorax with base widely sublobate, two marginal punctures on 

 each side; elytra narrow, impunctate, bimucronate at apex, border 

 not dentate at humeral angles; anterior tibire bidentate. Black; 

 prothorax widely margined with green; elytra greenish-black on 

 disc, green on sides and inflexed margin. 



Head lai-ge, transverse (4-5 x 6 mm.}, smooth; frontal sulci 

 long, deep, diverging strongly backwards; clypeus with median 

 part lunulate, declivous, intermediate angles strong, dentiform; 

 preocular sulcus well marked ; preocular process small ; eyes 

 deeply enclosed in orbits posteriorly, convex, not prominent ; 

 postocular process large, as prominent as eye, obliquely and 

 gently narrowed behind ; two supraorbital punctures on each 

 side. Prothorax broader than long (5'4 x 6-5 mm.), widest a little 

 in front of posterior angles, depressed on disc, not declivous to 

 base in middle; sides subparallel, narrowed gently from anterior 

 marginal punctures to anterior angles, widely rounded at postei'ior 



' N. cyliudripeniie. Bates, omitted from above list, is evidently associated 

 with 2^. elon(/nfum, Macl. 



t N^. rngosuln/n, Alael., has the prothorax the same shape as N. parvicex)s.
