572 STAPHYLINIDZ. 
The single example differs from the unique Amazonian type in several minute points 
of form, colour, and sculpture, so that it may prove to be not really conspecific. 
7. Sciocharis subnitens. 
Fusca, antennis pedibusque testaceis, elytrorum lateribus abdominisque apice ferrugineis; capite transversim 
subquadrato, oculis majoribus, obsolete punctato; prothorace crebre subtiliter punctato, subopaco, medio 
linea sat lata levigata. 
Long. 3 millim. 
Hab. Panama, David (Champion). 
Head short and broad, straight behind, the hind angles only very slightly rounded ; eyes 
large and convex, occupying two thirds of the length of the sides; surface very finely 
and obsoletely punctate, on the disc almost impunctate. Thorax small, much narrowed 
behind, covered with a fine subgranular punctuation, leaving the surface a little 
shining, especially on the basal region, and with a broad smooth line down the middle 
which is very feebly canaliculate at the base. lytra closely and finely punctate, 
slightly shining. Front tarsi undilated. 
Closely allied to the Amazonian S. egena, Sharp, but with considerably larger eyes 
as well as less important differences in the colour and sculpture. Unique. 
8. Sciocharis testacea. 
Testaceo-ferruginea, elytris pedibusque flavis ; capite subquadrato, oculis convexis sat magnis, dense subtilis- 
sime punctulato ; prothorace crebrius subtiliter granuloso-punctato, medio linea levigata. 
Long. 3 millim. 
Hab. GuaTEMALA, Panzos, Paso Antonio (Champion); Nicaragua, Chontales 
(Janson). 
This insect is closely allied to S. subnitens, but, in addition to the colour distinctions, has 
a rather narrower head, with eyes occupying scarcely more than one half of the length of 
the sides, and the punctuation on the basal portion of the thorax is not so scanty. One 
example from each locality. The exponent from Paso Antonio may prove distinct, being 
of rather larger size and darker colour, with some minute differences of punctuation. 
9. Sciocharis nitidicollis. 
Fusca, abdomine fusco-ferrugineo, apice dilutiore, antennis pedibusque testaceis ; capite transversim subquad- 
rato, posterius recte truncato ; prothorace nitido, tantum obsolete punctulato. 
Long. 3} millim. 
Hab. Panama, San Miguel in the Pearl Islands (Champion). 
The eyes occupy more than one half of the length of the short head, which is quite 
straight behind, the angles not at all rounded, the surface finely punctulate, a little 
shining. Thorax strongly transverse, quite shining, finely punctate, with no smooth 
area along the middle, but with an indistinct channel bebind. Elytra closely and 
finely punctate, blackish, shining. 
This distinct little insect is nearest to the Amazonian Lithocharis ardua,Sharp. Unique.
