450 STAPHYLINIDA. 
25. Pederomimus basipennis. 
Angustior, rufus; capite nigro, elytris abdomineque postico nigris, illis basi rufa, hoc ante apicem flavo-cingu- 
lato; antennis pedibusque rufis, his tibiisque apicem versus, illis medio, fuscescentibus; thorace seriebus 
dorsalibus fortiter 6-punctatis ; elytris crebre fortiter punctatis. 
Long. 7} millim. 
Hab, Panama, Chiriqui (£7d0e). 
This is a species apparently closely allied to P. ornatellus, but with numerous points 
of minor distinction; the antenne are less elongate, the penultimate joint being 
scarcely longer than broad ; the thorax is rather more slender, and a little more rounded 
at the anterior angles; the hind part of the insect is black, with a yellow fascia on the 
base of the terminal and hind margins of the penultimate segments dividing the black 
colour; and the antenne and legs are infuscate in part. ‘The unique example, which 
is in a decayed, and to a certain extent discoloured, condition, is apparently a female. 
26. Pederomimus distans. | 
Rufus; capite nigro-zneo, elytris [basi excepta] abdomineque ante apicem nigris; antennis minus gracilibus, 
basi rufa; prothorace seriebus dorsalibus 7- vel 8-punctatis, inter series has punctis adjectis quatuor ; 
pedibus testaceis, nigro-spinulosis. 
Long. 8 millim. 
Hab. Guatemata, Zapote (Champion). 
Antenne rather long and stout, the penultimate joint rather longer than broad. 
Head very shining, brassy black, rather narrow; with numerous coarse punctures, 
leaving a broad space on the middle quite smooth. ‘Thorax pale red, with a very 
slight brassy reflection; with a crowded dorsal series of seven (on one side) or eight 
(on the other) large punctures, on the space between these, just behind the middle, 
with four other punctures quadrately placed, and also with about seven other large 
punctures on each side. Elytra black, rather broadly red at the base, shining, coarsely 
punctate, the punctures at the base finer and denser. Hund body with the two penul- 
timate segments black, the hind margin of the hinder of them, as well as the terminal 
segment, yellow; middle lobe of the armature yellow; apical styles, except at the 
extreme base, black. Legs yellow, the tibie slightly infuscate. 
This species is a very abnormal one in the genus, the mandibles and palpi being less 
slender and elongate than usual, and the prosternum only very indistinctly divided, so 
that the genus is doubtful; the basal joint of the hind foot is a good deal longer than 
the apical joint. Only one example has been met with, and its sex is uncertain; possibly 
it may be a female, and in that case the male might show the species to be an aberrant 
mimetic Belonuchus. 
27. Pederomimus cribratus. (Pederomimus cribricollis, Tab. XI. fig. 24.) 
Rufus; capite, metasterno abdomineque ante apicem nigris; capite superne enescente ; elytris (basi excepta)
