CAMPSOPYGA PALLIDIPENNIS. (Plate XXXVI. fig. 8.) 
Elongato-fusiformis, subdepressa, nitida, fere glabra, piceo-brunnea vel nigro-picea, ore, 
antennarum basi thoracisque marginibus testaceis; elytris piceo-testaceis, basi et 
lateribus saturatioribus; capite et thorace leviter punctatis; elytris leviter striato- 
punctatis, interstitiis impunctatis; abdomine levissime punctato. Long. 2} lin., 
.lat. 3 lin. 
Habitat in Venezuela. 
Somewhat elongate-fusiform, subdepressed, shining, slightly punctate, almost glabrous, 
piceous, with the antennz (except the club, which is fuscous), the mouth, the sides of 
the thorax, and the legs testaceous; the breast fuscous; the elytra piceo-testaceous, with 
the base and sides darker. Head finely punctate, with an impression on each side behind 
the epistome. Thorax finely and sparsely punctate, a little longer than the head, about 
a half broader than long, transverse, widest about the middle, slightly narrower in front 
than behind; sides rounded, apex very slightly emarginate; anterior angles rounded, 
posterior obtuse; base slightly bisinuate; the testaceous margin rather broad, and en- 
eroaching a little both on the base and the apex. Scutellum rather large, rounded at 
the apex, slightly punctate. Elytra a half longer than the thorax, a little wider than its 
base, punctate in rows, the interstices not punctate, punctures roundish ; humeral angles 
nearly right-angled, rounded; apex obliquely truncate; exterior apical angles rounded, 
sutural angles right-angled, shoulders not prominent; suture, base, neighbourhood of 
scutellum and shoulders, sides, and apex all a little darker than the disk and somewhat 
fuscous. Abdomen slightly convex, finely punctate, and slightly pubescent. 
This species has much general resemblance to the species which I have described 
under the name of Prosopeus subeneus, from the Cape of Good Hope. 
From Venezuela. Received from the Berlin Museum, and now in the British Museum. 
Genus HYPODETUS (éré8eroc, shod, bearing shoes or sandals,—in allusion to the 
dilated tarsi). 
Caput oculis magnis, basin ejus attingentibus; epistomate porrecto; sulcis antennariis convergentibus. 
Mandibule cuspidate. Ligula angustata, sine alis. "Thorax elytris angustior. Elytra striata vel 
subcostata. Abdomen postice attenuatum ; segmentis omnibus (ultimo maximo excepto) fere zequali- 
bus; fimbriis fere parallelis, pygidii postice angustioribus. Tarsi valde dilatati. 
Body elongate, and somewhat conical at each end. Head rather broad; the eyes very 
large, reaching to the base of the head; and the epistome very prominent, narrow, 
and projecting. Labrum transverse, faintly emarginate. Mandibles with the sides 
straight, bicuspid, with a slightly bearded lamella on the inner side (Pl. XX XV. fig. 6 7). 
Antenne with the basal article large and dilated, second article subglobose, third longer, 
fourth short, fifth longer, sixth shortest and smallest of all, seventh and eighth gradu- 
ally a little wider, ninth to eleventh forming the club, the eleventh being the largest 
(PL XXXV. fig. 6 a). Antennal grooves short and converging. Maxillary lobes moderate 
in size, shortly bearded all over from the point for nearly half their length (Pl. XXXV. 
fig. 6f). Maxillary palpi not very stout, with the second and terminal articles longest
