neiv genera and species of Tenchrionido', (§-c. 297 



CiiARiANUS, nov. gen. 



Differs from Tetraphyllus in the nientum strongly and 

 more regularly convex, not at all carinate ; the larger and 

 more extruded labrum, the membranous hinge entirely 

 visible; head much narrowed and shortened in fi'ont of 

 the eyes, and swollen behind them ; eyes above narrower, 

 inwardly prolonged and contracted, more distant from 

 the prothorax; antennary orbits smaller, more convex, 

 more rounded ; cpistoma convex, broadly and squarely 

 truncated in front, front angles distinct, sides short but 

 distinct and not continuous with the sides of the anten- 

 nary orbits; the suture strongly transversely impressed 

 and sending off at each side, at an obtuse angle, a more 

 finely-impressed line, which terminates at the junction of 

 the antennary orbits with the sides of the epistoma; pro- 

 thorax squarer, much less deeply emarginate in fi^ont, 

 front angles more obtuse; base more bisinuate, not much 

 wider than the apex ; sides much more gradually expanded 

 to behind the middle, thence more strongly, abruptly and 

 incurvedly contracted to the hind angles ; side margins 

 a little reflexed and finely crenulate ; apical margin very 

 fine, almost obsolete; elytra obliquely widened from the 

 base to the shoulder where they become angulate ; sides 

 distinctly compressed, and subparallel, at the middle, 

 dilated behind ; the strite very distinctly punctured ; epi- 

 ])leural fold not rapidly expanded at the base, not nearly 

 attaining the humeral angle ; prosternum abbreviated 

 direct up to the coxfe ; the process shorter and acutely 

 triangular; intercoxal process much narrower; triangular, 

 pointed at apex. 



It may also be added that the head, the prothorax and 

 its flanks, are closely studded with deeply and clearly 

 impressed, rounded puncture* • ^^^'^ flanks of the meso- 

 and meta- sterna, the epipleural fold and the legs are also 

 very distinctly punctured, the latter somewhat densely so. 



Type. — Tetraphyllus purpuratus, Coq. 



Amarsenes, nov. gen. 



Head as in the preceding genus, but the eyes above are 

 not perceptibly contracted ; the antennai* are very short ; 



» In my examples of Charianvs, the antenna; are, nnfortunatcly, 



wanting.
