440 STAPHYLINIDZ. 
Antenne rather elongate; the basal joint, and the base of each of the two following 
joints, red. Mandibles and palpi elongate, clearred. Head with very numerous coarse 
punctures, but with a space smooth along the middle. Thorax a good deal narrowed 
behind, the serial punctures moderately coarse. lytra shining ; broadly red at the base, 
reddish along the suture, and with the hind margin very narrowly flavescent, elsewhere 
black ; sparingly and not very coarsely punctate. Hind body broadly red at the base, 
then black, the apical segment yellow, the anal styles black. The hind femora are 
slightly infuscate externally. Although closely allied to P. gentilis this species has 
numerous slight points of distinction, and the very much more sparing punctuation of 
the elytra makes it distinguishable at a glance. 
Only one example has been found; it is a male, with a few spines on the middle of 
the front femora, and a broad, rather deep notch on the last ventral plate. 
3. Pederomimus chontalensis. 
Rufus ; capite, elytris (basi excepta), abdomine ante apicem antennisque in medio nigris, his articulis duobus. 
ultimis cum abdominis apice pallide flavis; elytris ad angulos exteriores breviter flavescentibus, parce 
punctatis ; prothorace seriebus discoidalibus minus subtiliter 5-punctatis. 
Long. 9 millim. 
Hab. Nicaracva, Chontales (Janson). 
Antenne rather elongate and slender; the three basal joints red, the next six black, 
the terminal two pale yellow. Head black, with moderately numerous coarse punctures. 
Anal styles pale fuscous at the extremity. 
This is another ally of P. gentilis, from which it is readily distinguished by the less 
elongate thorax with coarser punctures, and by the more sparingly punctate elytra. 
These points bring it near to P. mandibularis, with which it cannot, however, be united 
on account of the two pallid terminal joints to the antenne. 
Only one example, a female, has been found; it has no spines on any of the femora. 
4. Pederomimus salvini. (Tab. XI. fig. 18.) 
Rufus ; elytris (basi excepta), pectore, abdomine ante apicem antennarumque medio nigris; elytris minus crebre 
punctatis. 
Long. 10 millim. 
Hab. Panama, Bugaba 800 to 1500 feet, Volcan de Chiriqui 2000 to 3000 feet 
(Champion). 
Antenne elongate and slender ; the three basal joints red, the next six black, the two 
terminal joints ferruginous. Head with afew coarse punctures behind. Thorax narrowed 
behind, only moderately long, the dorsal series consisting of five rather fine punctures, 
and also with about five other punctures of similar size on each side. Scutellum 
densely punctate, red. Elytra black, with a rather narrow red fascia at the base, each
