60 LUCANID-*. 



long and slender, the terminal fork long, its tips not very 

 divergent.

SiKKiM : Lingtu, Paramtsin. 



Type in M. Rene Oberth r's collection. 



The male type-specimen from which I have made the above 

 description is a rather small individual. Its recorded habitat 

 is Sikkim only. The female, from the locality given above, 

 was captured seven years later. 



L. oberthuri has a close resemblance at first sight to L. 

 atratus Hope, but the points of difference are numerous. It 

 is a more elongate insect, with the club of the antenna shorter 

 in both sexes, but especially in the male, and with the front 

 tibia finely serrate between the lateral teeth. The pronotum 

 is less punctured, the lateral margins are less strongly angulate, 

 and, in the male, only the median part is shining, the sides 

 being finely rugulose and opaque. The extremities of the 

 elytra are dull and sooty in both sexes.

Black or deep reddish-black, the male coppery above, the 

 female with dark coppery el^'tra, the lower siu'face clothed 

 with yellowish hair, fairly long upon the metasternum. The 

 elytra very glossy in both sexes. Moderately elongate and 

 convex, with the front and hind angles of the pronotum 

 sharply produced, the base strongly margined, with a slight 

 fovea just before the middle. The scutellum punctured and 

 clothed with fine hair. The club of the antenna short, the 

 seventh joint a little shorter than the three terminal ones, 

 and the sixth slightly produced. The front tibia finely and 

 sharj)ly serrate, with three or four rather larger lateral teeth. 

 The middle tilia has about three lateral spines and the hind 

 tibia only one. 



9. The head is much narrower than the prothorax, coarsely 

 and rugosely punctured, with the sides rounded in front of 

 the eyes, the clypeal jiroccss prominent, narrow and jjentagonal. 

 The prunotnm is moderately shining, except at the sides, which 

 are granular and o})aque ; it is very finely and sparsely 

 ])un(tured in the middle and more strongly and closely in 

 front. The sides are gently roimded in front and strongly 

 concave behind, the front angles fairly and the liind angles 

 very sharj). I'he elytra are more glossy at the sides than in 

 the dorsal pait. Tlie front tibia is very broad and very closely 

 serrate latei-ally. 



rj. Tlie head is broadei' than Ilu> prothorax and very short.
