Oblong, parallel at the sides, rather convex ; the forehead 

 excavated, distinctly punctured between the eyes, stria 

 transverse, sinuous, oblique near the eyes, ocular tubercle 

 conspicuous ; the thorax wholly punctate, marginal stria fine 

 and sinuous at the sides, obscurely crenulate behind the neck ; 

 the elytra, strise well impressed, 1-8 complete, third turning 

 towards tlie second at the apex, fourth broken before the base, 

 fifth apical, nearly reaching the middle, sutural nearly com- 

 plete, terminating behind the scutellum ; the propygidium 

 irregularly punctate, subfoveolate at the sides ; pygidium 

 evenly and rather densely punctured ; the prosternum, keel 

 carinate, widening out at the base, without stria, anterior lobe 

 sparsely punctulate ; the mesosternum rather widely emar- 

 ginate in front, stria strong at the sides, fine and scarcely 

 meeting behind the emargination ; the metasternum is bistriate 

 on each side, each stria well separated ; the sternal plates are 

 smooth ; the anterior tibiae are 4-dentate. 



This species is certainly congeneric with Hister ci/Ii'n- 

 driciis, Payk., which is the type of the genus Cylistix^ 

 Marseul. 



Hah. Perak (low country). One example.

Oblonga, parallela, nigra, nitida, supra punctulata ; fronte trans- 

 versim impressa ; pronoto stria interna brevissima ; elytris striia 

 1^-3" integris, 4* dimidiata, S^-O" basi abbreviatis ; prostcruo 

 bistriato.

Oblong, parallel at the sides, black, shining; the forehead 

 transversely impressed, stria strong and oblique over the eyes, 

 angulate in front of them, and very fine within the frontal 

 impression ; the thorax evenly but not densely punctured, 

 with some fine points dispersed between the coarser ]ninc- 

 tures ; the elytra, the first stria is complete and continues 

 along the base of the elytra, and in continuing turns towards 

 the suture just before reaching the scutellum, forming thus a 

 margin to the base of each elytron, the second and tliird are 

 complete, the third joining the margin formed by the first at 

 the base, fourth apical, shortened and puuctiforin in the 

 middle, fifth longer and punctiform from the middle, sixth 

 longer and not ending in punctures ; between the fifth stria 

 and the suture are scattered dorsal punctures ; the propy- 

 gidium and pygidium are clearly and somewhat densely 

 punctured ; the prosternum, keel carinate, widening and 

 bistriate at the base, anterior lobe sparsely and obscurely
