478 A SECOND NOTE ON THE CARENIDES, 



but lightly convex before tlie eyes, and crossed by a well-marked 

 pre-ocular sulcus ; margin of elytra narrow behind first ventral 

 segment ; the humeral projections of the elytral border strong 

 and erect ; anterior tibiae bidentate ; the apical plate narrow and 

 projecting downwards at apex in a strong triangular prominence ; 

 intermediate tibiae with a strong external spur at apex. 



As points distinguishing it from Enio)iia the following may be 

 noted : — The spaces between the frontal sulci and the sides of the 

 head (in Eittoma roundly convex before the eyes, with the pre- 

 ocular sulcus indistinct across them), the margin of the elytra (in 

 Eutortia thick, and forming an evenly rounded head or edge to the 

 elytra), the apical plate of anterior tibiae (in Eutoma broad and 

 obtuse at apex). 



I place in Neocaremi'^n the two following species, though they 

 are both so extremely isolated that I feel doubtful if I am right 

 in not forming a new genus for each ; however, as their affinities 

 are, in a general way, towards Neocarenum, and as I am, with 

 my i»resent imperfect knowledge of the tribe, loth to form new 

 genera among the Carenides, I prefer to include them in iVeocare- 

 nuiti, giving descriptions to show their many points of difference 

 from one another and from all other species known to me. 



Neocarenum angustatum, n.sp. 



^. Very elongate, subcylindiic ; black, smooth; elytra of same 

 width as prothorax, a row of widely-placed strong punctures 

 extending along middle of each elytron from shoulder to apex ; 

 anterior tibiae bidentate. 



Head large, convex (4*25 x 5*5 mm.), 'obsoletely transversely 

 impressed behind ; frontal sulci strongly impressed, very divergent 

 backwards, curving sharply out in front in a strongly marked 

 course ; pre-ocular sulcus lightly marked, arched ; pre-ocular 

 process not prominent ; clypeus with a strongly projecting tooth 

 at each side of labrum ; the anterior margin trisinuate between 

 these teeth, the sinuosities about equal and forming a well-marked
