and its Neo-Tropical Allies. 75 
thorax longer than broad, rounded at the sides, coarsely 
punctured, a faint smooth line in the middle ; scutellum 
triangular ; elytra scarcely broader at the base than the 
prothorax, flattish in the middle, the sides nearly 
parallel, seriate-punctate, preapical callus slight ; body 
beneath and legs chocolate-brown with a few scattered 
scales ; tibie short; claw-joint small. 
A peculiar narrow species with no obvious ally, but 
very like, only a longer outline, Cholus rana (Fab.). 
Cholus may be best distinguished from Hilipus by its 
anterior coxe not bring contiguous at the base. 
Hilipus circulatus. (Pl. IL., fig. 2.) 
H. ovatus, niger, opacus, vitta silacea laterali, antice 
posticeque confluentibus, instructus; femoribus fortiter 
punctatis. Long. 6 lin. 
Hab. Ucayali. 
Ovate, opaque black, a broad regular well-marked 
stripe running round the sides of the prothorax and 
elytra, and confluent at both extremities, but only ex- 
tending to the margin of the elytra at the apex ; rostrum 
much shorter than the prothorax, scarcely curved, and 
shghtly glossy ; antenne piceous; club as long as the 
last five joints of the funicle ; prothorax rather longer 
than broad, slightly rounded at the sides, the disk with 
a few lightly impressed punctures; scutellum small, 
rounded, glossy ; elytra slightly convex, broadly rounded 
at the apex, punctures in lines, very minute; body 
beneath and legs rather glossy ; femora coarsely punc- 
tured ; claw-joint moderate, two basal joints narrowly 
triangular. 
This species may be compared to H. tricolor (Ol.), and 
H. medioxinus, Boh., but differs from both in seulpture ; 
there are several other species (velamen, crocopelmus, 
lactarius), but none have the stripes confluent. 
Hilipus hipporhinoides. 
H. subellipticus, piceo-fuscus, squamulis silaceis valde 
aspersis, instructus ; elytris striato-punctatis, interstitiis 
alternis clavatis, rubidis, granulatis, apice singulorum 
rotundatis. Long. 6 lin. 
Hab. Columbia. 
_Subelliptic, pitchy brown, with minute scattered 
silaceous scales; rostrum moderately curved, longer
