Mentum very deeply emarginate, lateral lobes nearly straight, 

 very sharp at the tip, median part narrow and with a short, well- 

 defined slender median tooth, truncate at the tip ; ligula carinate in 

 the median part, triangularly ampliate towards the apex, slightly 

 bisinuate at the tip, which bears two moderately long setae, one on 

 each side of the median slightly projecting part ; paraglossse very 

 slender, disconnected from the ligula a little above the basal part, 

 lobate, slightly incurved and hardly longer ; second joint of labial 

 palpi very short, third clavate, fourth fusiform and truncate at the 

 tip, third and fourth of maxillary palpi slender at the base and then 

 abruptly swollen, the fourth one truncate at tip ; mandibles robust, 

 arcuate ; labrum long, deeply incised in the centre w^ith one deep 

 setigerous puncture in the angle, and two setae on "each side ; clypeus 

 broad, transverse, sinuate in the anterior part, with one broad punc- 

 ture on each side ; head much prolonged behind the eyes, elongato- 

 quadrate ; eyes prominent, two supra-orbital setae ; antennae filiform, 

 groved externally, the three basal joints glabrous, the third one nearly 

 as long as the following two together ; prothorax elongate, longer 

 than broad, almost straight laterally ; elytra oblong, broader than 

 the prothorax, striate, and convex ; legs long, slender, intermediate, 

 and posterior tibiae arcuate, deeply grooved externally ; tarsi long,

Black, moderately shining ; labrum, palpi, and antennae, with the 

 exception of the three basal joints which are black, piceous red ; 

 head nearly smooth, with a semicircular impression above the 

 clypeus, and a deep though short longitudinal one on each side ; 

 prothorax nearly straight laterally, but slightly attenuate in the 

 anterior part, outer margins recurved, sharp, median longitudinal 

 groove reaching from base to apex ; posterior angular part slightly 

 obliquely truncate ; disk smooth ; elytra one-third broader than the 

 prothorax, with the basal part sloping towards the humeral angle, 

 oblong, convex striate, faintly punctate with the intervals convex, 

 subcarinate in the centre, the interval between the eighth stria and 

 the outer margin subpunctulate ; under side piceous black ; abdomen 



' * Herr H. J. Kolbe has suggested that Bhopalomelus should be included 

 among the Chlcenides, Arch. Naturg. Ix., i. ; I cannot, however, agree, with him.
