334 - STAPHYLINIDZ. 
Hab. Panama, David (Champion). 
Antenne short, joints 6-10 transverse. Hind body but little opalescent, the two | 
terminal segments entirely red, as well as the styles; the first segment has only a very 
few punctures, and these do not extend as a complete series across its base; the 
following segment has a complete series across the base and some punctures at the 
sides, and the three following segments are more evenly, though still only sparingly, 
punctate; the tarsi, though flavescent or rufescent, have the basal joint piceous. 
Only a single female has been found of this species. Although very similar to 
Q. flavicaudus, it has a narrower head and shorter antenne, and also the elytra slightly 
shorter, with more conspicuous punctures, and differs too a little in the details of colour 
and punctuation. 
13. Quedius mexicanus. 
Niger, nitidissimus; abdomine sat iridescente, apice late testaceo; antennis tarsisque testaceis, illis basi picea, 
oris partibus rufis; elytris prothoracis longitudine, punctis nonnullis setigeris conspicuis impressis ; 
capite orbiculato. 
Long. 11 millim. 
Hab. Muxico, Cordova (Sallé), Mirador (Hége). 
This is another of the extremely closely allied species of this group, and is best 
distinguished by the flavescent or rufescent antenne, which are paler externally than 
at the base, this latter part being indeed piceous, and by the pallid tarsi. The hind 
body is not quite so sparingly punctured as in the allied species, but, as in them, the 
punctuation is deficient on the middle of the basal segments. 
I have seen only two females, which do not agree exactly, as in one the punctuation 
of the hind body is finer and the legs are paler in colour, the femora being piceous: 
in both individuals the anterior tibiz are deeply infuscate yellow. 
14. Quedius verecundus. 
Niger, nitidissimus ; mandibulis tarsisque versus apicem piceis, abdomine purpureo-versicolore, crebrius zqualiter 
punctato ; capite transversim orbiculato; elytris thoracis longitudine, punctis grossis seriatim im pressis. 
Long. 13 millim. 
Hab. Panama, Volcan de Chiriqui between 2500 and 4000 feet (Champion). 
The antenne are short, scarcely so long as the head and half the thorax, and are 
very little thickened externally; joints seven to ten being a little transverse. The 
elytra possess very large punctures, nine or ten extending from the base to the apex 
along the suture, and a series of seven or eight within the shoulder, and four or five 
large punctures are placed obliquely between these series ; on the outer margin there is 
another series, and the epipleural series is very regular and distinct. The punctuation 
of the hind body is rather coarse and moderately close; on the basal segment it is absent 
from a small space on the middle of the hind margin.
