264 RHYNCHOPHORA. 
The funiculus is one-jointed, but there appears to be a groove on the outer face only 
of the pedicle of the club, which may be an incomplete expression of a second joint. 
It is, however, impossible to satisfy oneself, even with high magnification, whether 
the line visible is a groove or a displaced hair crossing the club. 
BRACHYSPARTUS. 
Brachyspartus, Ferrari, Borkenk. p. 65; Hichhoff, Rat. Tom. p. 429. 
This genus, established for the reception of a single species, B. moritzi, Ferr., from 
Venezuela, is allied to Corthylus, from which it is distinguished by the possession in 
both sexes of an antennal club of a rounded lozenge-shape, longer than broad and 
pointed at its apex, and of tibize which have the upper border curved and finely serrate 
for its whole length, the hinder pairs being flattened and widened towards the apex. 
The tarsi are short, with the basal joint scarcely longer than either of the succeeding 
joints. In the type the body is cylindrical, with truncate elytra divaricate at the apex 
of the suture. 
Two examples from Central America agree in possessing these characters, although 
the elytra differ somewhat, having a bluntly rounded declivity without divaricate 
sutural angles, and in one specimen the antennal club is longer and cheliform in 
outline. A more important distinction is the possession by both of a two-jointed 
funiculus; whereas that of B. moritzi is described and figured both by Ferrari and 
Kichhoff as consisting of a single joint. A close examination of the type of that 
species has, however, shown at least an indication of a second joint in the form 
of an indistinct suture separating off the pedicle of the club on its outer face. 
The prothorax has a narrowly-raised side-margin from the hind-angles to the 
anterior border; the base also is margined in &. moritzi, and one of our new 
species, B. ebeninus, but not in the other, B. barbatus; the prosternum is excised 
almost to the anterior coxe. 
Both sexes of 6. moritzt are known; the male characters, according to Eichhoff, are 
greater acumination of the antennal club, a convex forehead, and the presence of two 
well-marked tubercles on the apical margin of the prothorax ; the female characters, 
according to the same authority, are a less acuminate club, an excavate forehead, and 
less development of the prothoracic tubercles, which are, however, not absent. The 
application of these characters is presumably conjectural and may have to be revised: 
that derived trom the prothoracic tubercles would not hold good in Corthylus ; but, 
from a note made when I saw Ferrari’s type, I believe that Eichhoff made a slip, 
and that the tubercles are more strongly developed in the sex which he calls the male. 
The sex of either of our specimens cannot well be determined.
