( ) 
mimerous; black portioti of the elytra confined to the basal 
margin and sometimes obsolete. 
Punctured somewhat like longiusculiim, Grav. but is 
much smaller and differently coloured. 
0. L. sphcericoUe, Elackisli; thorax orbicular^ convex; 
aiiteniije long. 
Inhal). Indiana. 
Body black piceoiis ; head with the carinaof the antennse 
a little elevated^ abrupt before : antennm muck thicker to- 
wards the tip^ rather longer than to the base of the thorax, 
first joint hardly longer than the second and third together; 
fuscous, three basal joints honey yellow, fourth and termi- 
nal joints obscure honey yellow; larger joints hardly long- 
er than broad : mandibles bifid at tip, and with the palpi 
piceoiis : neck distinct: ihoi^ax ntarlj orbicular, a little wi- 
der before the middle and narrower behind ; convex, with 
sparse black hairs; elytra with scattered, upright hairs; sub- 
sutural stria deeply indented, particularly tow^ards the base ; 
tip truncate not sinuate; taken together, transverse quad- 
rate: tergwm bVdck: feet yellowish: thighs tow^ards the 
tip piceous. 
Length over one- tenth of an inch. 
Thelabrum is longitudinally indented in the middle and 
at tip is widely, but not very deeply emargiriate* The hab- 
it differs from that of most of the species, and it cannot he, 
rigidly speaking, congeneric with bicolor andpallipes^ Grav« 
It varies in having the feet entirely yellowish and the 
tips of the carinse of the head honey -yellow. 
7. L* millepiinctatum, Piceous ; with dense, minute piiiie- 
tures ; thorax with a glabrous line, rounded behind. 
Inhab. Indiana. 
Body dull piceous, with very minute, crouded puncturea 
and small hairs : head larger than the thorax, black-piceous, 
quadrate, almost lobed at the posterior angles : antennm 
mouth paler, rufous : thorax, as in Staphylinus, rounded 
behind and truncate before ; a dorsal, slender, glabrous line : 
elytra paler on the humerus : tergum dark piceous, posteri- 
or margins of the segments and lateral margin paler: be- 
neath honey yellow*, head rufous. 
Length less than one-fourth of an inch. 
The form of the thorax and head is that of a Staphylinus ; 
which together with the dense and minute puncturing, dis- 
tinguish this species very readily from others.
