292 STAPHYLINID. 
Antenne as long as head, thorax, and elytra, slender, not at all thickened towards 
the extremity ; the five basal joints yellow, the others infuscate; third joint shorter 
than second, fourth longer than broad; from this to the tenth, each is a little longer 
than its predecessor ; the terminal joint elongate. Head small, black, sparingly punc- 
tate. Thorax very convex, broader than long; the anterior angles extremely deflexed, 
the surface sparingly punctate. Elytra a good deal longer than the thorax, obscure 
reddish, largely black in an irregular manner at the sides, closely punctate. Hind 
body densely punctate, the seventh segment and hind portion of the sixth yellow. 
Legs very slender. 
The unique specimen is in fragile condition, and has the surface rather worn, but has 
probably been clothed with a pale, fine, not very short pubescence. 
BARYCHARA. 
Corporis forma Oligote simillima, convexa, brevis, posterius acuminata. Antenne filiformes, undecimarticu- 
late. Coxe intermedize distantes ; mesosternum carinatum. Tarsi breves. 
The little insect for which this generic name is proposed appears to connect 
Euryglossa and Saphoglossa with Oligota, as it has quite the appearance of the latter 
genus; but it has the filiform eleven-jointed antenne of the former, with which it is 
clear that its short tarsi (whose terminal joint shows not the slightest incrassation) 
will not allow it to be associated. It thus appears probable that it may prove to be 
the link required to connect the Oligote with the other Aleocharini having but four 
joints to all the feet. I regret I cannot completely expose the characters of this 
form, as the only individual of the minute species is in fragile condition, and its under - 
surface and feet are clogged with gum-tragacanth. It does not appear to possess any 
special affinity with Hypocyptus, though its size, form, and general appearance 
suggest such. 
1. Barychara filicornis. (‘I'ab. VI. fig. 24.) 
Convexa, posterius acuminata, nitida, parce punctata, picescens, pedibus fusco-testaceis; antennis flavis, elon- 
gatis, gracilibus, apicem versus haud crassioribus. 
Long. 13 millim. 
Hab. Guatemata, Zapote (Champion). 
Antenne pale yellow, not as long as head, thorax, and elytra, without the slightest 
differentiation of the terminal joints; each joint longer than broad; terminal joint as 
long as the two preceding together. Head rufescent, scarcely half so broad as the 
“thorax, sparingly punctate. Thorax transverse, transversely convex, shining, scarcely 
punctate. Elytra rather longer than the thorax, sparingly punctate, with a very scanty 
but not short pubescence. Hind body short, attenuate behind, indistinctly punctate, 
but with 1ather elongate scanty pubescence, 
Only a single specimen has been found.
