AMERICAN PHILOSOPHICAL SOCIETY. 571 



bifid at tip, and with the palpi pieeous ; neck distinct ; thorax 

 nearly orbicular, a little wider before the middle and narrower 

 behind ; convex, with sparse black hairs ; elytra with scattered 

 upright hairs ; subsutural striae deeply indented, particularly to- 

 wards the base; tip truncate, not sinuate; taken together, trans- 

 verse quadrate ; tergum black ; feet yellowish ; thighs towards 

 the tip pieeous. 



Length over one-tenth of an inch. 



The labrum is longitudinally indented in the middle, and at tip 

 is widely, but not very deeply emarginate. The habit differs 

 from that of most of the species, and it cannot be, rigidly speak- 

 ing, congeneric with hicolor and palHpes Grav. [456] 



[Belongs to Apocellus. — Lec] 



It varies in having the feet entirely yellowish and the tips of 

 the carinsB of the head honey-yellow. 



7. L. MILLEPUNCTATUM. — Piceous ; with dense, minute punc- 

 tures; thorax with a glabrous line, rounded behind. 



Inhabits Indiana. 



Body dull piceous, with very minute, crowded junctures and 

 small hairs ; head larger than the thorax, black piceous, quad- 

 rate, almost lobed at the posterior angles; antennae and mouth 

 paler, rufous; thorax, as in Stajjhylinus, rounded behind and 

 truncate before ; a dorsal, slender, glabrous line ; elytra paler on 

 the humerus ; tergum dark piceous, posterior margins of the seg- 

 ments and lateral margin paler; beneath honey-yellow, head ru- 

 fous. 



Length less than one-fourth of an inch. 



The form of the thorax and head is that of a Staphi/Unus; 

 which, together with the dense and minute puncturing, distin- 

 guish this species very readily from others. 



[Belongs to Lifhocharis, and previously described as Pxderus 

 corticinus Grav. — Leg.] 



8. L. CONFLUENTUM [coNFLUENS.] — Piceous ; densely punc- 

 tured ; thorax short, rounde'd behind and angulated before each 

 side; head large. 



Inhabits the United States. 



Body piceous; head with close set, discoidal punctures; large, 

 ovate or subquadrate; tips of the carinse of the antennae, base of 

 1834.]
