582 Coleopterological Notices, T. 



silvery hairs and long erect setae ; punctures fine but strong, very dense on the 

 pronotum, smaller and much sparser on the elytra, the latter rather shining 

 and with feebly impressed longitudinal lines. Head three-fifths as wide as 

 the pronotal disk ; eyes large, prominent, densely pubescent ; antennte closely 

 approximate, nearly as in Pelonoinus ; last joint of the maxillary palpi nearly 

 twice as long as the third, slender, subfusiform, slightly thicker beyond than 

 behind the middle, acuminate toward apex. Prothorax two-fifths wider than 

 long, the sides very feebly convergent from base to apex, feebly arcuate, 

 straight near the basal angles, broadly, strongly sinuate near the apical, the 

 latter acute and obliquely, anteriorly prominent ; apex truncate; base trans- 

 verse, deeply bisinuate, emarginate at the scutellum ; disk evenly convex, 

 the side-margins acute. Scutellum well developed, a little wider than long, 

 rounded anteriorly, strongly angulate behind. Elytra three-foui'ths longer 

 than wide, barely three times as long as the prothorax, gradually feebly 

 inflated behind, at base as wide as the protliorax ; apex broadly, obtusely 

 ogival ; disk declivous behind. Prostetnum greatly developed before the coxae, 

 broadly arcuate, the sublateral fissures behind the eyes open but short, tri- 

 angular ; coxae rather widely separated, the process obtusely acuminate, cari- 

 nate along the middle, received iu the deep mesosterual aperture. Legs short ; 

 femora stout, densely pubescent ; tibiae and tarsi more sparsely clothed with 

 longer flying hairs ; tibial spurs small, remote ; posterior tarsi two-thirds as 

 long as the tibiae, nearly as in Pelononuis. Length 5.3 mm. ; width 2.5 mm.

The structure of the intermediate cox^e and of the adjoining parts 

 of the metasternum is so radically different from Pelonomus, that I 

 am forced to separate this species generically, although its facies is 

 completely that of Pelonomus. The type is a male, having the 

 last joint of the anterior tarsi dilated, more broadly than in Pelo- 

 nomus, gradually more inflated toward base and with its under 

 surface sensitive, though only feebly pubescent. 



NARPUS n. gen. 



Body narrow, convex, the elytra striato-punctate. Head re- 

 ceived rather deeply in the prothorax, the eyes moderately large, 

 nude, distant, somewhat coarsely faceted ; antennse widely distant, 

 inserted in fovese adjacent to the eyes ; epistoma large, feebly trape- 

 zoidal with the angles rounded, the apex broadly sinuato-truncate ; 

 suture fine, straight ; antennae and oral organs missing in the type. 

 Prothorax long, the pronotum very declivous at the sides, almost 

 vertical toward apex, without sublateral line, the margin acute, nar- 

 rowly reflexed'; hypomera only iuflexed very slightly beyond the 

 vertical, wide, the inner margin wide and thickened, still more so
