PADEROMIMUS. | A441 
outer hind angle yellow. Hind body red, with the two penultimate segments black, 
the hind margin of the latter, together with the terminal segment, yellow; the 
armature also is yellow, the sete by which the middle lobe and the styles are terminated 
being, however, blackish. 
The male has the front femora furnished in the middle beneath with a few spines, 
and the last ventral plate emarginate by a broad moderately deep notch. 
5. Pederomimus capitatus. 
Rufus, nitidus; capite abdominisque fascia lata ante apicem nigris; antennis fuscis, basi picea; elytris nitidis, 
sat crebre punctatis ; prothorace seriebus discoidalibus 5-punctatis. 
Long. 104 millim. 
Hab. Mexico, Jalapa (Flohr, Hoge), Playa Vicente (Hoge). 
Antenne evidently thicker externally ; the basal joints elongate; after the middle 
each joint is conspicuously shorter than its predecessor, so that the penultimate joint is 
transverse ; the terminal joint not elongate. Mandibles and palpi red. Thorax bright 
red, its punctures not coarse. Elytra shining, rather dilute red, rather sparingly 
punctate. Hind body red at the base, but with the two or three (or even four) penul- 
timate segments black or blackish; the hind margin of the penultimate and the greater 
part of the terminal segment, yellow, the latter as well as the anal styles infuscate 
behind; legs yellow. 
The colour and sculpture of the elytra and the structure of the antenne readily 
distinguish this species from P. gentilis, of which it is an ally. The colour of the base 
of the antenne, and the extent of the black abdominal fascia, is apparently variable ; but 
I have seen only four examples: one of these is a male, and has about six spines on the 
front femora, none on the hind; the extremity of its hind body has been destroyed; the 
femora of the female are unarmed. 
6. Pederomimus hilaris. (Tab. XI. fig. 19.) 
Sanguineo-rufus ; capite thoraceque viridi-cyaneis, nitidissimis ; abdominis elytrorumque posticis nigris ; antennis 
in medio nigricantibus, articulis duobus externis flavis; prothorace seriebus dorsalibus 5-punctatis. 
Long. 9 millim. 
Hab. Paxama, Volcan de Chiriqui 3000 to 4000 feet (Champion). 
Antenne rather elongate ; the three basal joints red, the next six nearly black, the 
two terminal joints yellow ; the penultimate joint a little longer than broad. Mandibles 
and palpi red. Head and thorax very brilliant, blue-green in colour; the former 
rounded and narrowed behind the eyes, with rather numerous punctures about the 
sides; the thorax slender. Scutellum with a few coarse punctures on the middle. 
Elytra with only very distant punctures, very shining, the basal half red, the posterior
