Reddish -brown, very darli upon the liead and thorax and 

 the outer edges of tlie elytra, the male dull above, the female 

 very glossy, the middle and hind femora blotched with orange, 

 as well as the front femora and all the tibiae in the male. 

 The body rather narrow and clothed beneath with line close- 

 lymg pale hair, to be found also ujjon the front of the head 

 and the sides of the pronotum of the male. The club of the 

 antenna consists of four moderately long lamellae. 



(^. Dull brick-red, the mandibles, head and thorax darker 

 than the elytra. The head is very broad, densely granular 

 and opac|ue, its outer margm outhned by a sharp ridge, 

 nearly straight in front and interrupted in the middle behind, 

 the front angles projecting laterally beyond the eyes, which 

 are prominent. Tlie posterior lobes of the head are broadly 

 rounded. The cly2)eal pi'ocess is short, bluntly produced in 

 front and shar])ly elevated on each side at the base. The 

 pronotum is narrow, densely granular, with the sides strongly 

 but bluntly angular behind the middle and nearly straight 

 to the front and hind angles, of which the former are strongly 

 produced and the latter fairly sharp. The scutellum is strongly 

 and closely punctured. The elytra are smooth but scarcely 

 shining, very minutely and inconsi^icuously jjunctured, with 

 the shoulders sharply angular, the outer margins gently rounded 

 and the a])ices a little ])roduced. The legs are very long and 

 slender. 



In well-developed males the head is ver^' broad, the mandibles 

 are rather long, gently rounded externally ; the two branches 

 of the terminal fork are nearly equal ; there is a strong sharp 

 tooth just before the middle of the inner edge, inclined sUghtly 

 upward, and two or tliree small teeth before and after it. 



Length (with mandibles), 46 mm. ; (without mandibles) 

 31 mm. : breadth, 12 mm.

I have seen only a single male of the species. The Tibetan 

 type-specimen is also a single male, but a female froiii China 

 (represented in Planet's iig. 44) was associated with it by the 

 author. It is not at all certain that lie was riglit in this, but 

 the species is closely T'clated to the well- known (yhinese L. 

 fortiinei Sannd. and the female is no doubt much like that of 

 fortimei shown in the ])h()tograp]i on Plate IV, iig. I). The 

 male differs from tliat of fortiinei in having more convex, 

 ratliei' smootlier and less distinctly punctured elytra, with
