but prominent, the eye-ridge small, rovmdedand less prominent 

 than the eye. The head liears a slight l)ut sliarj) anterior 

 ridge, a slight transverse depression behind the ridge and a 

 short curved ridge on each side adjoining the eye. The 

 pronotiim is narrow, finely coriaceous, opaque at the sides but 

 shining in the middle : tliere is an almost round depression 

 just in front of the middle of the basal margin. The front 

 angles are produced and fairly shar]), the sides curved to the 

 middle, where they are bluntly angulate, and almost straiglit 

 to the very blunt hind angles. Tlie base is gently trisinuate. 

 The elytra are moderately sliining, except at the sides and 

 apices, which are finely coriaceous, the shoulders rounded. 

 The tibix are long and slender, the front tibia finely and 

 closely but unevenly serrate, the middle tibia armecl with 

 about three fine lateral spines and the liind tibia with a single 

 small spine placed at two-thirds of its length.

Owing to its deceptive appearance the t^^je-specimen was 

 described as a female. By the kindness of Herr Nagel I have 

 been able to examine it and to compare it with an exactly 

 similar specimen in M. Rene Oberthur's collection. Both 

 proved to be males. Females probably belonging to the same 

 species are to be found in M. Oberthur's collection and in 

 the British Museum. Those of the hitter collection were taken 

 in Tibet, one by Major R. W. G. Hingston in Rongshar Valley, 

 ]0,0C0 ft., June 1924, and two at Yatong, 10,500 ft., by Mr. 

 A. E. Hobson. They resemble the male rather closely but the 

 head is coarsely rugose and not dull, the pronotum roughh' 

 punctured at the sides and the elytra brownish and onl}' 

 feeblj^ metaUic. The legs are much less slender, the spines 

 upon the middle and hind tibi?e much stronger and the 

 antennae shorter.

I have not been able to examine the unique female specimen , 

 the type of this species, which almost certainly does not belong 

 to that described and figured under tlie same name three years 

 later, to which I have given the name Liicanus furcifer. 

 I therefore give here a translation of the original description 

 of that specimen, identical in the two references quoted above. 



" Tlie male of this species is not known, but, to judge by 

 the female, it must be near L. Innijer, for the resemblances
