Longicorn Coleoptera from China. 63 



only slightly concave between the antennal tubercles, the 

 latter not at all prominent. 



The prothorax is almost or entirely without transverse 

 grooves, is somewhat convex on the disk, and is very closely 

 punctured both above and at the sides. The scutellum is 

 pale grey. The elytra are punctate, of a brownish grey 

 mixed with a paler grey, the latter appearing mostly as a 

 very indefinite broken band on each elytron extending from 

 the shoulders obliquely towards the suture and thence along 

 to the apex. The cicatrice of tlie scape is scarcely apparent 

 in fresh specimens, in which it is covered by the pubescence; 

 it is incomplete. The joints of the antenntefrom the third 

 are testaceous and pale grey pubescent at their bases.

Long. 30-40 mm. 



Uab. China (Kiu Kiang). 



Head minutely and sparsely punctured, deeply and trian- 

 gularly concave between the antennal tubercles, with the 

 front somewhat depressed in the middle. Prothorax impunc- 

 tate, very shiny, somewhat constricted in front of and behind 

 the lateral tubercles ; these with a slightly posteriorly-directed 

 curvature and sharply pointed at their ends. The disk 

 somewhat obtusely tubercled or raised across the middle, the 

 median lobe or tubercle projecting a little on the posterior 

 transverse groove and triangularly notched behind. Elytra 

 black, very finely and minutely sculptured, so as to have a 

 coriaceous appearance, with a few minute scattered punctures 

 behind the shoulders. Body black and glossy below ; the 

 legs with a faint greyish pile; the tarsi with a pale greyish - 

 blue pubescence above. Antennse with the second joint and 

 the extreme base of the third joint bluish grey, the remaining 

 joints black. 



I have named this fine species after Mr. J. H. Leech, to 

 whom the British Museum is indebted for its specimens of 

 this and other species described in the present paper.
