and strongly inflexed behind by a rounded angle to the obtusely-rounded apical margin; surface 
cylindrical, strongly declivous behind, finely lineato-punctate, glabrous; declivity subconvex, nearly 
vertical below, narrowly impressed along the suture and raised on each side into a callus set with three 
small tubercles, and with afew short hairs. Legs as in B. ebeninus. 
Hab. Panama, Volcan de Chiriqui (Champion). 
One example, distinguishable from the last species by the characters of the forehead 
and antennal club, and the sutural sulcus and tuberculate calli of the elytral declivity. 
As B. barbatus and B. ebeninus are from the same locality, the question suggests itself 
as to whether they are the opposite sexes of one and the same species. I think that 
this is not so, although it would be difficult to give precise reasons. 
GLOCHINOCERUS, gen. nov. 
Antenne lateraliter inserte ; scapo sat longo, recto; funiculo 3-articulato; clava elongata, angusta, 3-articu- 
lata, suturis transversis; articulo ultimo ceteris sumptis fere equali, in medio constricto. Prothorax 
antice oblique declivis. lytra cylindrica, postice retusa, apice suture integro. Tibie antice anguste, 
curvate, extus granulate, margine superiore subserrato. Tarsi graciles. 
Mas. Fronte integra; antennarum clava breviore; prothoracis apice bituberculato. 
Fem. Fronte excavata, fasciata ; antennarum clava longiore ; prothoracis apice integro. 
Front deeply excavate and fringed in the female only. Antenne inserted in the ocular emargination, with a 
rather long straight scape, slightly wider and flattened towards the apex in the female; funiculus short, 
evidently 3-articulate, the first joint cupulate, the others conical and increasing in width; club elongate 
(especially in the female), flattened, triarticulate, with transverse sutures, the first joint triangular, the 
second transverse, the third nearly as long as the others together, obtusely pointed and subconstricted in 
the middle. Maxillary lobe (3) quadrate, produced at the inner apical angle into a short process densely 
fringed with fine curved sete, its inner border nearly straight, with longer straight sete; palpi inserted 
at the outer apical angle, the first two joints short, the third longer than broad: mentum (< ) inserted by 
a short triangular peduncle, long and narrow, constricted near the base, gradually widened, rounded and 
pilose towards the apex : ligula inserted about its middle, widened in front and surrounding the apex of 
the mentum; labial palpi contiguous at base, large, the first joint cupulate, subtransverse, the second 
nearly twice as long as broad, pilose externally, the third small, but not transverse. Prothorax obliquely 
declivous in front, its apex bituberculate in the male, the flanks impressed, but with no lateral raised 
margin ; prosternum short, closely embracing the coxe behind and subproduced in the middle. Elytra 
cylindrical, retuse, not emarginate or divaricate at the apex of the suture. Anterior femora broad, lobed 
at apex ; anterior tibie long, slender, curved, with feeble marginal serration, the outer face subasperate ; 
middle and posterior tibie widened and spatulate, the marginal serration almost obsolete. Tarsi long and 
slender, the first joint longer than either of the two following. 
The antennal club is similar to that of Anchonocerus and Phthorius, from both of 
which the present genus is distinguished by the triarticulate funiculus and subretuse 
elytra, without apical emargination. ‘The same characters distinguish Glochinocerus 
from Pterocycion ; and it is at present one of the best-marked genera in the Corthyli. 
‘Two species have been taken in Central America.
