610 STAPHYLINIDA. 
very narrow at the shoulders, shorter than the thorax, sparingly and finely punctate. 
Hind body broad, with the terminal two segments and the armature red. Legs black, 
the apices of the tibiae picescent, the tarsi pale. 
This is one of the most distinct species of the genus, and cannot be confounded with 
any other. Six examples were procured. Our figure represents a male. 
2. Pederus luridiventris. (Tab. XVI. fig. 2.) 
Elongatus, angustulus, piceus; elytris viridi-piceis, brevissimis, capite nigro, abdomine luride rufo; antennis, 
palpis pedibusque testaceis, femoribus extrorsum late fuscis. 
Long. 15 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui up to 6000 feet (Champion). 
Antenne long and slender. Head broad, subtransverse, only sparingly punctate. 
Thorax much narrowed behind, quite sparingly punctate. Elytra small, very short and 
narrow, transversely impressed, very sparingly, obsoletely punctate, of a peculiar fusco- 
metallic colour. 
Of this very distinct species a good series was obtained. We figure the male. 
Found in the dense forest, by beating the lower branches of the trees (Champion). 
3. Pederus testaceitarsis. 
Niger; antennis, palpis tarsisque testaceis, mandibulis flavo-piceis; capite parce punctato; elytris brevissimis, 
transversis. 
Long. 14-15 millim. 
Hab. Mexico, Istapan (Sallé). 
Antenne long and slender, immaculate. Head broad, quite sparingly and not very 
coarsely punctate. Thorax broad, scarcely so long as wide, but little narrowed behind, 
sparingly punctate, with a broad space along the middle impunctate. LElytra not quite 
so long as the thorax, broad and short, each deeply impressed, rather sparingly and not 
coarsely punctate. Hind body black, the terminal styles flavo-piceous. Tarsi yellow. 
I have seen only one pair of this species. It was labelled P. testaceitarsis, Fauv., in 
Sallé’s collection, and I have preserved the name. It is similar to P. rujitarsis, Solsky, 
but is larger and broader, with much less punctuation on the head, more elongate 
antenne, &c. 
4. Pederus salvini. 
Pederus salvini, Sharp, Trans. Ent. Soc. Lond. 1876, p. 431". 
Hab. Guatemata (Sallé), Aceytuno 5100 feet (Salvin !), near the city, San Gerdénimo, 
Capetillo, Duefias, Panajachel, Volcan de Atitlan (Champion); Panama, Volcan de 
Chiriqui 2000 to 3000 feet (Champion). 
This interesting species is apparently rather common in Guatemala, and does not 
vary. From the State of Panama we have obtained only one female example.
