STAPHYLINUS. 381 
of the thorax. Eight specimens have been found, one of which (a slender male) is only 
about 19 millim. long. 
24, Staphylinus apicipennis. 
Angustulus, niger ; capite, thorace elytrisque subzeneis, peropacis, his ad apicem griseo-pubescentibus ; abdomine 
fusco-subvariegato, in medio bifariam maculato, apice ferrugineo-nigro. 
Long. 19 millim. | 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). 
Head rather small, coarsely, very densely punctured ; eyes occupying about one half 
the length of the sides. Thorax evidently longer than broad, straight at the sides, 
extremely densely punctured, without any longitudinal smooth space. LElytra scarcely 
so long as the thorax, with a dark fuscous pubescence, which at the hinder part is 
replaced by a griseous pubescence. Scutellum velvet-black. Hind body blackish, 
with two rather widely separated black spots on the middle of each segment, and with 
an obscure admixture at the sides of pallid griseous pubescence; the hind margin of 
the sixth segment dark red, and also the whole of the seventh segment; anal styles dark 
red, black at the extremity. Under surface of head and hind body with a rather coarse 
punctuation. Femora black, middle and hind tibie blackish, streaked externally with 
yellow; tarsi dark, clothed rather densely with paler hairs. 
Described from a single, rather abraded male. It bears a great resemblance to 
S. antiquus, and might easily be passed over as of that species, from which, however, 
it is readily distinguished by the less extent of the sides of the head occupied by 
the eyes. It is very similar also to the Mexican S. incognitus, which, however, has a 
larger, more quadrate head, with denser, more confluent punctuation, and longer 
elytra. 
25. Staphylinus ignotus. 
Niger; capite, thorace elytrisque eeneis, illis dense fortiter punctatis, fusco-pubescentibus ; abdomine tomentoso- 
vestito, bifariam fusco-variegato, apice testaceo; mento magno transversim elliptico, eburnaceo. 
Long. 22 millim. 
Hab. Mexico, Mirador (Sallé); Panama, Volcan de Chiriqui 4000 to 6000 feet 
(Champion). 
Antenne rather slender, fuscous. Head broad; eyes rather prominent, large, occu- 
pying more than half the length of the sides.’ Thorax not so long as broad, straight 
at the sides, without distinct central smooth line. FElytra a good deal longer than the 
thorax, very dull, densely covered with very fine tomentum, and with a scanty pubes- 
cence besides. Hind body densely covered with fine tomentum, with two elongate 
obscure darker marks on the middle of each segment; the seventh segment and the 
anal styles yellow, the extreme hind margin of the preceding segment red. Legs 
fuscous black.
