variously modified in this genus; in bistrialus, for example, it 

 becomes broadly double, the anterior margin strongly biarcuate; 

 the trapeziform stria of mancus is also a peculiar and very diflPerent 

 modification. Three specimens. 



P. COmplexus. — Oblong-oval, moderately convex, polisliei, piceous- 

 black, the legs and antennae rufous ; punctures of the head and pronotum 

 very fine, sparse, even, of the elytra stronger but fine and rather sparser. 

 Head not impressed, the marginal stria extremely fine and feeble but entire. 

 Protborax three-fourths wider than long, the sides feebly convergent and just 

 visibly arcuate, becoming more convergent and arcuate toward the apex ; 

 marginal stria entire, not interrupted at apex. Elijtra nearly as long as wide, 

 three-fourths longer than the protborax, and, before the middle, only very 

 slightly wider ; marginal stria with a row of distinct punctures internally, 

 extending along the apex almost to the suture ; oblique basal striae feeble ; 

 sutural strong, straight, extending to basal third. Propygidium finely but 

 deeply, evenly and rather closely punctate, the pygidium finely, about equally 

 closely so, almost entirely occupied, except in basal fourth, by a large and 

 very deep, circular excavation, which is longitudinally divided along the 

 middle by a compressed carina, the bottom of the excavation coarsely granulose, 

 two or three of the tubercles near the posterior extremity ])eing large and 

 prominent. Presternum prominent and rounded behind, with two very short 

 subapical striae, the lobe large, strongly deflexed, not margined and more 

 strongly punctate ; mesosternum not margined at apex, the emargination 

 deep ; transverse suture feebly double, the anterior line unevenly, feebly 

 bicuspid. Anterior tibiae with four nearly equidistant external teeth. Length 

 1.9 mm. ; wid h 1.0 mm. 



Alabama. 



The single type is probably a male, the sculpture of the pygidium 

 being very remarkable. Comfjlexus is allied to Heminulum, but in 

 the male of that species the pygidium is simply vermiculate. 



0]VTIIOPHILUS Leach. 

 The following species is allied to leconlei: — 



O. SOltaili n. sp. — Evenly oval, moderately convex, polished, black, the 

 legs rufo-piceous. Head finely, strongly, very densely punctate, more sparsely 

 and coarsely so in the feeble iuipression between the slightly oblique latero- 

 frontal ridges ; epistoma large, evenly convex, trapezoidal, the suture obso- 

 lete. Prothorax twice as wide as long, the sides straight and parallel to the 

 middle, then abruptly, strongly convergent and straight to the apex, the apical 

 angles slightly obtuse and scarcely at all rounded ; disk strongly but not very 

 coarsely or closely punctate, the pumtures somewhat uneven, large and small 

 in size ; lateral margin thickened and strongly, abruptly reflexed ; lateral
