444 STAPHYLINIDA. 
12. Pederomimus vicinus. 
Rufus ; capite thoraceque nitidissimis, illo eneo, hoc wneo-micante, elytris ad angulos exteriores late fusces- 
centibus; antennis in medio fuscis; abdominis fascia ante apicem nigra; prothorace seriebus dorsalibus 
fortiter 5-punctatis ; elytris fortiter punctatis. 
Long. 8 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Very closely allied to P. punctipennis, but rather larger, and with the antenne a 
little longer, and the elytra without brassy tint ; in most other respects similar, so that 
it may possibly prove to be only a local variation of P. punctipennis. 
Only one female, in bad condition, has been found. 
13. Pederomimus simplex. 
Fulvus; capite thoraceque eneis, nitidissimis; elytris abdominisque apice nigris, illis basi rufa, hoc testaceo- 
cingulato; antennis pedibusque testaceis, illis in medio obscuratis; prothorace seriebus dorsalibus 
5-punctatis ; elytris fortiter punctatis. 
Long. 7 millim. 
Hab. GUATEMALA, near the city, San Gerdédnimo and San Joaquin in Vera Paz 
(Champion). 
Although very similar to P. pectoralis, this is a much smaller and feebler insect, and 
has the breast but little infuscate, while the black colour on the wing-cases extends 
much nearer to the base. 
In the male there is a scarcely perceptible emargination of the last ventral plate ; 
but when the legs are extended this sex is readily distinguished, as the hind tibie are 
a good deal dilated, being, except at the base, nearly twice as thick as they are in the 
female. 
A small series was found at San Gerénimo, and single examples at each of the other 
localities. | 
14. Pederomimus mexicanus. 
Fulvus ; capite thoraceque fuscis, subeenescentibus ; elytris ad angulos posteriores abdominisque apice nigris; 
antennis testaceis in medio fuscis ; pedibus pallide testaceis ; elytris fortiter punctatis. 
Long. 6 millim. 
Hab. Mexico, Jalapa (Hége). 
Although very closely allied to P. simplex, this insect presents too many points of 
difference to allow of its being considered a mere variety thereof. It is smaller, with 
less brassy head and thorax; the elytra are shorter, with fewer punctures, and with 
the black colour occupying only one half their surface, and the black colour of the . 
hind body is less definite and extensive in front. 
Only one example has been found; it is a male, having the hind tibie dilated 
as in P. simplex.
