angles; base broadly arcnate, oblitjue and straight toward the basal angles, 

 Avhicli are obtuse but not at all rounded, and with a thick confusedly punctate 

 bead; disk finely, sparsely inmctate, smooth and polislied, only very feel)ly 

 rugulose near the sides. Elytra scarcely more than one-third longer than wide, 

 a little wider than the i>rothorax and somewhat more than twice as long, par- 

 allel, the sides feebly arcuate, becoming straight near the base; disk obli(iuely 

 narrowed at apex, each elytron rounded; lateral margins reflexed ; punctures 

 fine and rather sparse. Abdomen more densely cinereo-puljescent. Length 

 3.8 mm. ; width 1.9 mm.

The description refers to a single female type from an unre- 

 corded part of the State. The epipleunv are rather wide, sub- 

 horizontal, polished and impunctate, becoming iuAvardly arcuate 

 at tip and vanishing only at the beginning of the rounded apical 

 angles. It is probable that the male will be found to ditier con- 

 siderably in general form. 



2. Ell. o1)loii§:us n. sp. — Oblong, stout, strongly convex, polished, black, 

 without metallic lustre, the elytra somewhat piceous; legs pale rufo-ferrugin- 

 ous throughout, the coxai dark; antennse rufo-testaceous, blackish toward apex 

 and also at the inner extremities of the intennediate joints ; pubescence cin- 

 ereous, subdecumbent, long and very sparse anteriorly, rather dense and inter- 

 mingled with sparse erect pale set;c throughout on the elytra, the head with 

 a few bristling setiis; marginal cilia long and ratlier confused. Hiad scarcely 

 more than three-lifths as wide as the ]n-othorax, smooth, finely, sparsely punc- 

 tate, the impressions long and pronounced, extending almost to the occiput; 

 ei)istoma somewhat sliort; laln'um moderate, rounded; eyes rather large, mod- 

 erately convex; antennie stout, serrate, incrassate, moderate in length, the 

 penultimate joints strongly transverse. Prothorax three-fifths wider than long, 

 the sides very slightly convei-gent and extremely feebly arcuate from base to 

 apex, the basal angles nearly right, not rounded and distinctly prominent 

 laterally; apical angles ])roniinent anteriorly, acute and not in the least blunt; 

 apex sliglitly narrower than the base, broadly, arcuately emarginate; l)ase very 

 feel)ly arcuate toward the middle; disk minutely and remotely punctate, not 

 in the least rugose near the sides. Elytra two-fifths longer than wide, not 

 wider than the i)rothorax, parallel and straight at the sides, broadly rounded 

 at apex, each elytron narrowly truncate, with the sutural angle blunt; disk 

 narrowly reflexed at the lateral margins, rather finely but strongly and some- 

 what closely punctured. Abdomen a little more densely cinereo-pubescent. 

 Length 2.9-4.8 mm.; width L4-2.2 mm.

The male descril)ed has the fifth ventral truncate at apex, the

 sinuato-truncate at apex and the inner spur of the anterior and
