ti-ansversely notched posteriorly ; prosternvim well developed in front, the 

 suture distinct; anterior coxae moderately larofe, conical, contigvioiis ; inter- 

 mediate coxae narrowly separated ; legs long, slender ; tibiae each with two long, 

 snh-equal, simple spurs, the intermediate and posterior pairs notched along their 

 upper edge; penultimate joint of the anterior and intermediate tarsi short, 

 bilobed, that of the 2:>osterior pair long, simple ; anterior tarsi feebly dilated in ^ ; 

 body sub-cylindrical. 



Type : D. quadricostatus. 



The two Eastern species referred to this genus are very closely re- 

 lated to Dapsiloderus Fairni., butjdiifer from it in the serrate maxillary 

 palpi, vfith cultriform apical joint, and the second joint much shorter, 

 the narrowly sulcate genae, the smaller anterior coxae, the gi'eater 

 development of the ante-coxal portion of the prosterni;ni, the long 

 mesosterual process, and the non-contiguous intermediate coxae. 

 These insects superficially resemble various Eucnemids (Hylotastes), 

 Lycids and Clerids, though they are really very nearly allied to Dir- 

 caea. The greatly widened, compressed, serrate antennae, and general 

 coloration, give these insects a Lycid appearance. The sexes are 

 scai'cely distinguishable by external characters. 



1. — ■Dapsiloderinus quadricostatus, u. sp. 



Very elongate, narrow ; black, the prothorax and elytra wholly or in part 

 brick-red or fiery-red, the prothorax usiially with a narrow median vitta (some- 

 times much widened anterioi'ly or extending to the greater part of the svirface), 

 and the elytra with the apex, to a greater or less extent (and, rarely, also the 

 suture to the base), black, the palpi (except in one specimen) flavovis ; very 

 densely, minutely punctiilate, and thickly clothed with fine pubescence, the 

 latter partaking of the ground-colour, sometimes brownish-cinereous on the 

 sides of the prothorax and on the head. Antennae long, reaching to the second 

 or third ventral suture, joints 3-10 very, broadly serrate, 11 narrower than 10. 

 Prothorax broader than long, the sides somewhat compressed at the middle and 

 sub-parallel at the base, the latter bisinuate, the disc canaliciilate posteriorly. 

 Elytra quadricostate, the outer sub-marginal ridge just traceable, the base 

 strongly, transversely asperate, the sutui'e also asperate beyond the middle. 

 Length 7-10^, breadth li-2J mm.
