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, striz well impressed, 1-3 complete, third turning 
towards the 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 
regularly 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 tibiz are 4-dentate. 
This species is certainly congeneric with Hister cylin- 
dricus, Payk., which is the type of the genus Cylistiz, 
Marseul.

Oblonga, parallela, nigra, nitida, supra punctulata ; fronte trans- 
versim impressa; pronoto stria interna brevissima; elytris striis

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 punc- 
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 third are 
complete, the third joining the margin formed by the first at 
the base, fourth apical, shortened and punctiform 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
