moderate sulcus; antennae moderate, the seventh funicular joint much 

 wider, forming part of the club, the combination large, oval and not quite 

 as long as the rest of the funicle; prosternum nearly flat, not armed in the 

 male, the coxae small, somewhat widely separated. [Type M. tubulatus nov.] 



Microtorcus 



Prothorax not tubulate at apex, except very briefly in Anatorcus 21 



21 — Prosternum canalate. Body slender, parallel and strongly sculptured; beak 

 moderate, not separated by an impression; antennae submedial, with very 

 small and narrowly oval club, the coxae well separated; elytra with feeble 

 humeral prominences and strong grooves. [Type T. scidptilis nov.] 



Torcobius 



Prosternum flat 22 



22 — Beak short, thick, obtuse at tip and closely sculptured, the antennae far 

 beyond the middle; body slender, parallel and closely sculptured; antennae 

 moderate, the club small, oval, abruptly separated from the almost equally 

 wide, compact distal part of the funicle, its basal segment more than half 

 the mass; all the funicular joints beyond the first are closely compacted 

 and more or less transverse; coxae well separated and also well developed; 



elytral humeri subobsolete. [Type A. densus nov.] Anatorcus 



Beak rather short and thick, strongly sculptured, separated by a moderate 

 impression; antennae beyond the middle, with somewhat abrupt and moder- 

 ate, ovoidal club; anterior coxae well separated; elytral humeri feebly 



though evidently prominent. [Type 5. ruginasus nov.] Sibariopsida 



Beak only moderately long but always slender, more or less smooth and cylindrical, 



the antennal club well developed, oval and abrupt 23 



23 — Elytral humeri and general habitus nearly as in the preceding, the sides 

 usually not exactly parallel; beak smooth, sparsely punctulate, sometimes 

 tumid at base at the feeble sulcus; antennae medial or but little beyond; 

 prosternum sometimes bispinose in the male. [Type Centrinus confinis 



Lee] Sibariops 



Elytral humeri obsolete, the body rigidly parallel, loosely sculptured; beak 

 slender, smooth and arcuate, separated by a very feeble sulcus; antennae 

 slender, medial, the first funicular joint as long as the next two, the second 

 nearly twice as long as wide, the club abrupt, longer than the preceding 

 four joints, its basal segment half the length; anterior coxae narrowly sepa- 

 rated. [Type P. lustralis nov.] Pseudotorcus 



24 — Body parallel, the dense pale elytral squamosity fasciiform in arrangement; 

 prothorax not tubulate at apex; beak rather short and thick, more or less 

 densely sculptured, the antennae beyond the middle and with moderate 

 oval club; prosternum flat, the coxae moderately separated; elytra with 

 very feeble humeri and rather deep grooves. [Type T. fasciatus nov.] 



Torcus 

 Body similarly exactly parallel but more depressed, feebly sculptured, the pro- 

 thorax with a very short but abrupt apical tubulation; beak rather long, 

 very slender, smooth and cylindric, arcuate, the antennae behind the middle, 

 somewhat slender, with well developed and abrupt oval club; prosternum 

 flat, the coxae well separated; pale elytral vestiture partially fasciiform. 



[Type P. quadrifer nov.] Paratorcus 



25 — Femora unarmed; tarsal claws small and very slender, either connate at 



base or extremely approximate 26 



Femora serrato-denticulate medially beneath 29 



26 — Anterior coxae' moderately separated; tibiae straight 27 



Anterior coxae larger, approximate; femora apically and the tibiae bent 28 



27 — Body very narrow and elongate-suboval, smooth and glabrous; beak thick, 

 truncate, not separated from the head by an impression; antennae slender,
