TELCHIS. 143 
ovate ; mandibles extending a little beyond the prominent exserted labrum (which is separated from the 
epistoma by a distinct clypeus), bifid at the apex; antenne short (reaching only to the first third of the 
prothorax), perfoliate, the first and second joints stout, the second short, the third to the eighth very 
short, strongly transverse, very closely articulated, and slightly widening outwardly, the ninth joint fully 
twice the width of the eighth, the ninth to the eleventh forming a very large, loosely articulated club, the 
Jomts of which are strongly and broadly produced on the inner side, the eleventh bluntly rounded at the 
apex, the joints of the club (and the labrum) coarsely setose; head long, strongly exserted, the lateral 
margins of the front slightly swollen, and extending triangularly forwards beyond the epistoma (which 
1s broadly but not deeply emarginate in front), and not impinging on the eyes behind; eyes lateral, distant 
from the prothorax, not very large, the superior portion rounded, the space between them armed with a 
strong erect transverse prominence (which is distant from the eyes, extends forwards, and is abruptly 
declivous in front, and covers in greater part the short epistoma); prothorax rather broader than long, 
longitudinally convex, distinctly margined at the sides, the disc deeply excavated in the middle; scutellum 
small, narrow; elytra rather wider than and closely embraced by the prothorax, about twice as long 
as the prothorax, very convex, cylindrical, narrowly margined, regularly and coarsely punctate-striate 
from the base, without scutellar stria, the interstices convex; legs much as in Daochus, the external 
denticulation of the anterior tibia stronger (armed with two short and three long teeth), the teeth on the 
intermediate tibie stronger, the apices of the posterior tibiz more produced ; tarsi very sparingly clothed 
with hair beneath, the first joint of the posterior pair short and thin, the length of the two following 
joints united ; epipleure narrow (slightly constricted in the middle), extending to the apex of the elytra; 
prosternum rather broad, declivous behind; metasternum long, deeply impressed longitudinally behind ; 
intercoxal process triangular. . 
This genus will include a single species from the State of Panama. I have only seen 
two examples: these are possibly male and female, as they were taken together, though 
they have the head and thorax similarly formed; analogous cases are known in the 
allied genera. 
Telchis is perhaps best placed near Peneta, to which, however, it is not. very closely 
allied; it may be known at once by the very large, loosely articulated 3-jointed club of 
its antenne, cylindrical form, excavated thorax, and other characters given above. 
1. Telchis clavicornis. (Tab. VII. fig. 5*; 5a, mentum; 56, maxilla and | 
maxillary palpus; 5 ¢, antenna.) 
Elongate ovate, subcylindrical, very convex, black, shining. Head coarsely and closely, the anterior face 
of the transverse frontal elevation much more closely and finely, punctured; prothorax a little broader 
than long, narrowing a little before and behind, the angles obtuse (the anterior ones slightly prominent, 
but not produced), the base subtruncate, the disc broadly and very deeply excavate in the middle (the 
excavation open in front, and bounded anteriorly by a sinuous transverse impression, sinuous at the sides), 
with an elevated smooth longitudinal ridge from the centre of the excavation behind to the base, the 
surface very coarsely, but not very closely, punctured; elytra subparallel, narrowing a little at the extreme 
base, the humeri small but distinct, coarsely punctate-striate (the punctures transverse and closely placed), 
the interstices strongly corivex, and sparingly and finely punctured ; beneath shining, coarsely punctured, 
the metasternum and the ventral surface in the middle smoother. 
Length 53-6 millim. (¢.) 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet (Champion). 
Two examples. 
* In the figure given the thorax and elytra (especially the latter) are badly drawn; the whole insect is much 
more elongate, and narrower.
