356 STAPHYLINIDA. 
mine nigro, segmentis singulis testaceo-marginatis, segmento 7° ex parte majore testaceo ; pedibus testaceis, 
antennis rufo-obscuris basi dilutiore. 
Long. 10 millim. 
Hab. Panama, Bugaba (Champion). 
Antenne with the three or four joints pale red, the others darker. Head and thorax 
shining brassy, coarsely punctate, the former with the disk broadly smooth, the latter 
with a smooth space along the middle. Scutellum and elytra densely punctate. Hind 
body very densely and finely punctate; segments 2-6 with the hind margins yellow, 
that of the sixth more broadly than the others; seventh yellow, marked with black at 
the extremity; anal styles yellow at the base, black at the extremity. 
This insect is very similar in most respects to the smaller individuals of P. segmen- 
tarius, but is readily distinguished by the shining head and thorax and the densely 
punctured elytra and hind body. Only three individuals have been found; the sexual 
characters are apparently the same as in P. segmentarius. 
5. Philothalpus nigriventris. 
Niger; capite thoraceque superne eneis nitidis, elytris nigro-eneis, abdomine ante apicem testaceo-cingulato, 
palpis antennisque piceis, tarsis testaceis; capite thoraceque fortiter punctatis, abdomine crebrius subtiliter 
punctato. 
Long. 11 millim. 
Hab. Guatemaua, San Geronimo (Champion). 
Antenne rather elongate, even the tenth joint being evidently longer than broad, 
blackish at the base, rather paler at the apex. Mandibles reddish. Head shining 
brassy, with a few coarse punctures on the middle in front, behind these with a curved 
transverse series, and with other punctures at the margins of the eyes, hind angles, and 
vertex. Thorax also shining brassy, and rather coarsely punctate, and with a rather 
broad line along the middle impunctate. Thorax rather longer than the elytra, rather 
closely and not finely punctate. Hind body black, with a narrow margin at the extre- 
mity of the sixth segment, and with the base of the seventh segment yellow. Legs 
blackish, the base of the tibiz paler, the tarsi sordid yellow. 
This, again, is closely allied to P. segmentarius, but is distinguished by good 
characters of colour and punctuation. Only two specimens have been found ; and the 
sexual peculiarities are much as in P. segmentarius. 
6. Philothalpus pectoralis. 
Niger; capite thoraceque superne eneis, nitidis, elytris pectoreque rufis, pedibus testaceis; capite thoraceque 
fortiter punctatis, abdomine dense subtiliter punctato. 
Long. 12 millim. 
Hab. Guatemala, San Gerénimo (Champion). 
Antenne as long as head and thorax, black; palpi blackish, with the terminal joints
