164 STAPHYLINIDZ. 
body more narrowed behind, and therefore less parallel. Antenne stout, the two or 
three basal joints yellowish, third joint longer than second, fifth to tenth transverse ; 
eleventh large, acuminate, quite as long as the two preceding together. Thorax rather 
broader than long, a little narrowed behind, rather narrower than the elytra, sparingly 
punctate, the hind angle very obtuse. Elytra rather closely punctate. Hind body with 
segments two to four sparingly punctate, the fifth and sixth almost impunctate. Legs 
clear yellow. 
The unique individual before me is no doubta male; for although without distinctive 
characters on the hind body, the second, third, fourth, and fifth joints of the antenne 
are densely furnished on one side with sete. 
PHLCGZOPORA. 
Phieopora, Erichson, Kaf. Mark.-Brand. i. p. 314 (1837). 
This genus consists of about twenty species of minute Staphylinide, distributed in 
most parts of the world; but probably South and Central America are their head 
quarters. A considerable number of the Central-American species have their head 
borne on a comparatively narrow neck, and more disengaged from the thorax than 
their European congeners, and, in consequence of this and their more slender form, 
have a somewhat Falagrioid appearance ; but these species cannot be treated asa distinct 
genus, the gradations of structure being too numerous to permit of this. 
1. Phleopora fenestrata. 
Nigra, nitida, parce punctata et pubescens, antennarum basi palpisque fuscis, pedibus fusco-testaceis, elytris 
ad apicem testaceo-maculatis ; antennis crassis, articulis 5°-10™ fortiter transversis ; prothorace sat elon- 
gato, anterius rotundato, fortiter subobsolete punctato, linea media glabra, basi transversim foveolatia.

Antenne short and stout, thickened externally; fourth joint scarcely transverse, the 
following strongly so. Head broad, rather broader than the thorax, with narrow neck, 
black, shining, very sparingly punctate. Thorax longer than broad, a good deal 
narrower than the elytra, a little narrowed behind, with a rather coarse but indistinct 
punctuation, and down the middle a smooth space, at the base with a transverse 
impression, which is more or less distinctly divided by the smooth middle line, according 
to the direction from which it is observed. FElytra a little longer than the thorax, 
shining black, at the apex with a rather large yellow patch common to the two, 
sparingly punctate. Hind body slender, rather sparingly and not finely punctate; the 
seventh segment obscurely granulate, its extremity rounded. 
Six specimens have been found; I do not observe any sexual character among them. 
The rather elongate form, narrow neck, and rounded front to the thorax give to this 
and the allied species a somewhat Falagrioid facies.
