from tliere to the obtuse hind angles. The clijlra are shinuig 

 in the inner lialf, wliere they hear numerous rather fine but 

 deep punctiu'es, coarsely and denseW punctiu'cd on the outer 

 half, and the apices rugose. The lower surface is very finely 

 and sjjarsely punctured except the middle of the metasternvm 

 and the last ventral sternite, which are coarsely and closely 

 j)unctured. The front iU)ia is slender and slightly curved, 

 its extremit}^ palmate, with several vei-y short blunt lobes ; 

 the middle and hind tibiae have each a sliarp lateral spine. 

 ^. Red or chocolate, with the femora anfl tibiae brighter 

 red. Long and narrow, Avith very slender legs, the upper 

 surface entirely opaque except close to the suture. The head 

 and pronotum are finely and densely granular, the front 

 angles of the head obtuse, the sides gently rounded behind 

 the eyes. The clyjjeal process is small, cjuadrate and lathei- 

 tridentate in front. The mandibles are slender. Tlie front 

 angles of tlie pronotum are jiroduced but blunt, the sides 

 almost straiglit to far beyond the middle, Avliere they are 

 shari)ly angular, and feebly excised from there to the very 

 blunt hind angles. The elytra are smootli and finely punctured 

 near the suture and very densely confluently punctured 

 elsewhere. The shoulders are acutely angular. The abdomen 

 is smooth and has at its extremity a longitudinal ridge ending 

 in a tufted process. The front tibia is minutely serrate and 

 feebly toothed externally, with a fine terminal foi'k. and the 

 middle and hind tibi* are without lateral spine. 



Variatio7t of the male. \n small specimens the liead is 

 simply convex, with fairly numerous distinct jnmctures, the 

 l)asal half of the mandible sti-aight and serrate internally, the 

 terminal half gently curved. In larger specimens, in addition 

 to the basal serration, there are two or three teeth towards 

 tlie tip. Indications also appear of four transversely ]ilaced 

 tubercles u})on the vertex of the head. IModei-ately largei- 

 males have two very small but sliarply-elevated tubercles, 

 with two very feeble ones ])etween them, the inandibles are 

 about as long as tlie elytra and gently curved, with a short 

 stout tooth a little beyond the base, a minute one before tlu 

 apex and just before the latter, a short lamina, a little \)vo- 

 duced at the distal end. 



Specimens from Assam ar(> hiighter red than those from 

 the Darjeeling district, and the largest males are longer, they 

 have four strong cephalic tuberc-les and the mandibles ai-e 

 very long, with a strong sharp tooth placed at a right angle 

 about one third from the base, a smaller tooth at lu^ai'ly 

 two-thirds of the length, followed by a slioi-t laminar ])rocess 

 and a ilat triangular tooth between this and the tip.
