104 Memoirs on the Coleoptera 



Body above uniformly clothed with scales or squamules; femora not spiculate 

 beneath; antennal club oval, subequally trisected by distinct sutures; beak 

 notably thick 15 



15 — Beak evenly arcuate; antennal club abrupt; anterior coxae separated by less 

 than half their width; prothorax moderate, not constricted at apex. [Type 

 T. sparsa nov.] Thestonia 



Beak unevenly arcuate; antennal club gradual in formation; anterior coxae 

 separated more widely; prothorax notably large, constricted and subtubulate 

 at apex. [Type P. obtecta nov.] Parathestonia 



16 — Body stout, oval, glabrous; beak very slender except basally, at least in 

 the female; antenna? far behind the middle, the club thick, gradually pointed; 

 anterior coxae distant, separated by more than their own width; femora 

 slender, not denticulate beneath. [Type G. militaris nov.] Garnia 



17 — Tarsal claws two in number as usual 18 



Tarsal claws single 23 



18 — Mandibles straight, unequal; presternum with a narrow impressed channel; 

 anterior coxae separated by less than their own width; body elongate- 

 suboval, with distinct vestiture. [Type A. seriata nov.] Andiblis 



Mandibles dentate and decussate 19 



19 — Body glabrous or subglabrous; femora not denticulate 20 



Body conspicuously clothed 21 



20 — Body glabrous or subglabrous; presternum with a moderate and very 

 shallow sulcus, which is more or less sharply limited at the sides; scutellum 

 oval to transverse. [Type O. conicicollis nov.] Ovanius 



Body more broadly ovulate than in the preceding, remotely and minutely setulo- 

 squamulose; scutellum small; presternum broadly and shallowly canalate 

 and squamulose; anterior coxae moderately separated and having on each 

 internally an erect subquadrate plate in the male. [Type 5. ovulum nov.] 



Stethobaridia 



21 — Anterior coxae subcontiguous; presternum with a squamose channel, sharply 

 defined at the sides; mandibles somewhat prominent, though strongly 

 dentate; antennae long and slender, the first two funicular joints elongate; 

 femora denticulate beneath. [Type P. rufipes nov.] Roalius 



Anterior coxae separated by barely a third their width; presternum not channeled; 

 mandibles short, strongly decussate and obtuse when closed; antennae 

 short; femora wholly unarmed. [Type P. tecta nov.] Palocopsis 



Anterior coxae separated by about their own width 22 



22 — Presternum perfectly flat and continuously so between the coxae; antennal 

 club smaller, the first segment more than half the mass; upper surface and 

 all the strial intervals densely clothed. [Type P. nescius nov.]. . . .Palocus 



Presternum broadly impressed; antennal club more elongate-oval, subequally 

 trisegmented by the sutures; upper surface loosely clothed, the strial intervals 

 uniseriate. [Type M. sparsellus nov.] Micropalocus 



23 — Mandibles long, prominent and internally straight; antennal club large, 

 oval, not very much shorter than the funicle; body suboblong-oval, very 

 coarsely and densely punctate, with widely and evenly separated squamules, 

 in single line on the strial intervals. [Type S. rugulosus nov.] Starcus 



24 — Mandibles strongly dentate and decussate 25 



Mandibles not decussate, except apically, falciform, the inner edges broadly 

 sinuate from apex to base and not evidently dentate; femora not spiculate 

 beneath 34 



Mandibles not or but slightly decussate, but more or less distinctly dentate 

 within and prominent when closed 35 



Mandibles straight, prominent, not at all decussate, meeting on a straight even 

 to slightly irregular line when closed, the left mandible sometimes obtusely 

 dentate submedially within, or shorter than the right 45
