narrower than the anterior one, and with a broad, closely punctured 

 depression on each side ; elytra piceous brown, oblong, not broader 

 at the base than the anterior part of the prothorax, hardly convex, 

 narrowly striate, with the intervals plane, smooth, the third one 

 with three distinct punctures ; under side black. Length 6-6-|- mm. ;

^neous on the upper side, black underneath ; the legs and the 

 three basal joints of the antennae red, the other joints rufescent ; 

 head smooth, with a frontal impression on each side ; deep but not 

 arcuate; prothorax narrow, a little longer than broad, a little 

 ampliate laterally in the anterior part, narrowed from past the 

 middle, and with the posterior part almost straight, posterior angle 

 not obtuse, but not projecting, median groove reaching the transverse 

 impressions, lateral basal ones, narrow, straight, moderately deep; 

 elytra oblong, narrowly striate, with the intervals plane and smooth, 

 the three punctures are sometimes on the third stria instead of 

 being on the third interval ; outer margin narrowly rufescent. 

 Length 6 mm. ; width 2 J mm.

Mentum without a raedian tooth ; ligula long, truncate at tip ; 

 paraglossse disunited from it from near the base, and longer by about 

 one-quarter of the length ; palpi of Platynus ; labrum long, slightly 

 sinuate ; eyes large ; head narrowed behind ; antennae long, slender, 

 the first joint as long as the third but thick, second one very short ; 

 prothorax narrow, subcordiform ; posterior seta at the very apex of 

 the posterior angle, which is always more acute in the male, posterior 

 margin sharply recurved ; elytra broader than the prothorax by one- 

 half, oblong, strongly sinuate behind, nearly plane but somewhat 

 convex along the suture, very finely and closely aciculate and 

 narrowly striate ; the aciculation is so closely set that it gives the 

 elytra a silky appearance, three distinct punctures on the third 

 interval ; legs long and very slender, the three anterior tarsi of the 

 male elongato-cordate, not grooved, the fourth very slender, long. 



More slender than Platynus, although it is somewhat difficult to 

 differentiate from P. alacer, &c. ; the distinctive generic character is 

 the total absence of the tooth in the mentum. 



Euleptus occurs in Madagascar, and also in India (Himalaya).
