494 RHYNCHOPHORA. 
One specimen from each locality, the one from Purula abraded and showing that 
the “elevations” of the upper surface are almost entirely due to the fasciculate 
arrangement of the sete. This small species approaches the Venezuelan O. discretus, 
Faust, but is much smaller and narrower, and has more slender legs, &c. 
8. Oxypterus rubiginosus, sp.n. (Tab. XXIV. figg. 10, 10a.) | 
Oblong-ovate, narrow, nigro-piceous, the rostrum ferruginous, the legs rufo-piceous; thickly clothed with 
rusty-red and ochreous scales, the vestiture becoming much sparser at the sides and base of the elytra, 
the ochreous scales condensed into three lines on the prothorax and two short, faint, oblique streaks on each 
elytron, the feeble elevations on the latter densely clothed with coarse, erect, rusty-red, setiform scales ; the 
vestiture of the under surface whitish. Head densely, the rostrum sparsely and very finely, punctate, 
the eyes distant; joint 2 of the funiculus shorter than 1. Prothorax broader than long, somewhat 
rounded at the sides, narrowed and feebly constricted in front; closely, finely punctate, feebly binodose 
on the disc before the middle. Elytra more than one-half wider than the prothorax, convex, elongate- 
triangular, the humeri swollen and laterally projecting ; seriate-punctate, the interstices rugulose, 2 with 
two oblong setigerous prominences, one before and the other beyond the middle, and 4 with a smaller 
prominence at the commencement of the apical declivity. Legs rather long, the femora narrow, dentate. 
Length 3,-34, breadth 14 millim. 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
_ Two specimens. Smaller and narrower than the Venezuelan O. ochreatus, Faust, 
the prothorax feebly binodose on the disc, the elytra with four very conspicuous 
clusters of coarse, setiform scales near the suture at about the middle. 
EUXENUS. 
Euxenus, Faust, Stett. ent. Zeit. 1896, pp. 47, 50. 
This genus, based upon two Tropical-American species, is nearly related to 
Oxypterus, but differs from it in having less approximate eyes, sublinear, unarmed 
femora, &c. 
1. Kuxenus apicalis. (Tab. XXIV. figg. 11, 11 a.) 
Euxenus apicalis, Faust, Stett. ent. Zeit. 1896, p. 48°. 
Hab. Nicaragua, Chontales (Janson); Panama (Boucard; coll. Pascoe), Bugaba 
(Champion).— VENEZUELA, San Esteban }. 
Four specimens, all larger than the type. In this insect the elytra have the base 
and a large apical patch densely clothed with brownish-white or ochreous scales, and 
the suture is usually ochreous or ferruginous. The eyes are more approximate in 
E. apicalis and the other Central-American species than in E. posticus, Faust, the 
type of the genus Huxenus. 
2. Euxenus subparallelus, sp. n. 
Oblong-ovate, black ; thickly squamose, the head and prothorax brownish or ochreous, the prothorax with 
three very faint paler vittew, the elytra brown, with the apical declivity and the suture for some distance
