 i, p. 19, pi. 1, fig. 4 (1853). 



c?'. Black or very dark brown in colour. Head sparsely punc- 

 tured and subnitid in front, closely granulated and dull behind. 

 Antennae a little shorter than the body ; first joint reaching to the 

 hind margin of the eye, sparsely punctured and nitid ; third to 

 fifth sparsely punctured and glossy along the middle above, dull 

 on the poriferous areas along the edges ; last six joints almost 

 entirely poriferous and opaque, marked with some fine longitudinal 

 or reticulated carinae. Pronoturn sparsely punctured, with the 

 interstices minutely punctulate or rugulose ; feebly, or not at 

 all nitid, except on the two dorsal humps which are smooth 

 and glossy. Elytra very finely rugulose or granulate, for the 

 most part dull ; sparsely punctured and subnitid near the base. 

 Hind breast covered with tawny pubescence. Last ventral seg- 

 ment feebly sinuate at the apex. Tibia of the first two pairs 

 strongly and the femora less strongly asperate; front tibiae 

 i-ather strongly curved. 



5 . Antennaa reaching to the apical third of the elytra, much 

 narrower than those of the male and less serrate. Dorsal humps 

 of prothorax narrower and more glossy than in the male, the 

 rest of the pronotum more opaque. Hind breast pubescent as in 

 the male. Last ventral segment with rounded hind margin. 



Length 34-50; breadth 11-18 mm.

Type, L. subopacus, C. O. Waterh. 



Range. Southern India. 



c? . Head with the antennal supports divergent, separated by a 

 rather broad deep channel that extends from the clypeus on to the 

 vertex ; clypeus depressed, limited above by an arcuate suture ; 

 labrum transverse ; mandibles abruptly incurved towards apex, 

 with broad inner tooth near apex of left mandible and triangular 

 dilation at base of right ; labial palpi short, with last joint stout, 

 ovate. Eyes emarginate, upper lobes not very widely separated 

 from one another. Antenna as long as the body ; first joint 

 stout, reaching a little past the eye, third thickened, somewhat 

 prismatic in form, one-third longer than the first ; fourth one-third 

 shorter than the third ; fifth to tenth successively and gradually 

 shorter, acutely angulate anteriorly at the apex ; eleventh nearly 

 twice as long as the tenth, one-half of it consisting of a very distinct 

 appendix. Prothorax transverse, with a strong laterally produced 

 spine at the front angle ; a strong slightly recurved spine at the 

 middle with a smaller spine or tooth arising from its front edge 

 near the base and a short tooth at the hind angle on each side ; 

 notum feebly convex, finely and densely punctate and opaque, but
