PELTOXOTUS. 27 



Division I. PELTONOTINI. 



This group comprises only one peculiar genus, Pellonotua, with 

 five species, three of which are Indian. Peltonotus was originally 

 placed in the DxNASXiJf^:, with which it forms a link. A very 

 remarkable formation of the labruin is its chief characteristic. 

 This organ is not covered by the clypeus, but is plainly visible in 

 front of it, although the clypeus itself is not at all reduced, as 

 usual in those groups in which the labrum is extruded. The 

 mandibles ag.iin project a little beyond the labrum. The body 

 is rather loosely articulated together, the abdomen rather long 

 and not covered behind by the elytra, nor closely wrapped 

 by them at the sides. The legs are slender, clpthed with long 

 hair, with long spurs to the four posterior tibiae, and the claws 

 are movable and slightly unequal. The front legs of the male are 

 greatly thickened and modified. 



Nothing has been recorded as to the habits of these insects.

TYPE, Peltonotus morio, Burm. 



Range. Assam, Nepal, Burma, Indo-Chiria, Borneo. 



Body ovate, loosely articulated. Head not sunk in the pro- 

 iiotum. Eyes rather prominent. Clypeus broadly transverse, riot 

 separated by a suture behind and not hollowed, but rather convex, 

 with the front margin scarcely reflexed. Antennae 10-jointed. 

 Prothorax rounded at the sides and base and not closely h'tted to 

 the elytra. Scutellum rather long, straight-sided, and acute. 

 Elytra not long, exposing the abdomen behind. Pro- and meso- 

 sternuui not produced. Labrum horizontal, extruded, wide, 

 sometimes a little bilobed. Mandibles large and visible from 

 above, concave, nearly straight in front, with a lateral tooth or 

 angulation. Maxillae armed with four long and very sharp teeth, 

 the palpi slender. Labium rather long, narrowed towards the 

 extremity, strongly constricted at the insertion of the palpi, with 

 two fleshy ligular lobes at the end. Coxae contiguous, the front 

 ones very large and prominent. Femora and tibiae very hairy and 

 rather slender, the front tibia armed with three teeth, the others 

 bearing very strong apical spurs. The claws are only very slightly 

 unequal, except the front claws of the male, and the pulvilli are 

 large and end in two long bristles.
