222 RHYNCHOPHORA. 
2. Ectyrsus gibbipennis, sp.n. (Lab. XII. fig. 21.) 
Subovate, shining, nigro-piceous, the prothorax reddish in front, the elytra faintly mottled or fasciate with the 
same colour, the antenne, the anterior tibie and tarsi, and the intermediate and hind legs, ferruginous 
or rufo-testaceous ; somewhat thickly clothed with very long, erect, yellowish-white hairs, which show a 
tendency to form a denser cluster on each side of the suture at the middle, the suture itself bordered 
with shorter imbricate hairs. Head finely punctate; rostrum strongly curved, a little longer than the 
prothorax, punctato-sulcate at the sides and base, for the rest almost smooth, the antennz inserted at 
about the middle, the club of the latter ovate, much shorter than the funiculus ; eyes large, prominent, 
very narrowly separated. Prothorax a little broader than long, rounded at the sides, narrowed in front 
and behind, coarsely, closely punctate. Elytra much wider than the prothorax, comparatively short, 
gibbous, subparallel in their basal third, the humeri a little swollen; coarsely and deeply punctate- 
striate, the interstices convex, rather broad, sparsely punctulate and transversely wrinkled. Anterior 
tibie abruptly truncate at the apex, unguiculate, like the two other pairs. 
Length 23-3, breadth 14 millim. 
Hab. Panama, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Two specimens. This species may be recognized by its comparatively short, gibbous 
elytra, the ovate antennal club, and the abruptly truncate apex of the anterior tibie. 
E. albohirtus, Faust, is smaller and narrower, and has less convex elytra and fewer hairs.

A genus numerous in species in Tropical South America, whence thirteen have been 
described *, and with two representatives in the United States. Fourteen are now 
added from within our limits, some of these being extremely closely allied to, or 
inseparable from, the North-American forms. JP. splendens, Faust, from Venezuela, is 
a most brilliantly coloured insect. 
The Central-American representatives (none of which can be identified with those 
previously described from Colombia) may be tabulated thus :-— 
a. Species large and robust, Cioniform ; elytra with a large bare rounded 
space on the disc, and for the rest thickly pubescent; intermediate 
and hind femora each with a very minute tooth . . . . . . . . ctonoides, sp. n. 
b. Species smaller and less convex, with the general facies of a Rhinoncus. 
a’, Femora unarmed. 
a’. Legs comparatively elongate, partly or entirely ferruginous ; 
antenne long, with an elongate club. 
a’, Elytra with the sides and apex only pubescent . . . . . . rufipes, sp. n.
