472 COLYDIIDZ. 
Subfam. GEMPYLODINA. 
I have recently discussed the characters of this subfamily (Ent. Monthly Mag. xxix. 
pp. 256, 257); it is distinguished from all the others by the membranous border of 
the prosternum. The form of these insects is more or less elongate; in those in which 
it is very long, the prosternum projects beyond the prosternal process, thus giving rise 
to an arrangement similar to that of Nematidiwm ; this was considered by Leconte and 
Horn to be of a Rhynchophorous nature, but a study of the various forms seems to 
show that it is correlative with the elongation of these parts of the insect, and differs 
from species to species. 
ENDESTES. 
Endestes, Pascoe, Journ. Ent. ii. p. 91 (1863). 
This genus consists at present of two South-American species. It is a very isolated 
form, though I think allied to Mecedanum and Gempylodes. ‘The prosternum between 
the coxe is quite distinct, though narrow, and it does not extend over the coxe as in 
Colydium, but is immersed between them; behind the coxe it forms a rhomboidal 
process closely connected with the tips of the thoracic side-pieces. 
Reitter, who described the second species of the genus, thought Gempylodes identical 
with Endestes; but this supposition is quite erroneous, though the two have several 
points in common. 
1. Endestes sculpturatus, sp.n. (Tab. XV. fig. 5.) 
Subcylindricus, niger, antennis pedibusque piceis; fortiter sculpturatus, prothorace medio profunde sulcato ; 
elytris apice retuso, ibidemque interstitiis 2° 4°que costato-elevatis. 
Long. 44-54 millim. . 
Hab. British Honpuras, Belize (Blancaneaux) ; GuatemALA, Pantaleon, Las Mercedes 
(Champion). . 
Antenne with the joints preceding the terminal three somewhat enlarged, these 
latter very loosely connected, so that the antennee can scarcely be called clavate. Head 
very closely punctate, with a strongly raised carina extending the whole length of the 
side. Thorax very long, very convex transversely, front margin straight, the angles 
not produced ; the surface shining black, coarsely punctate; along the middle there 
extends a broad groove, the sides of which in front are subcostate; there is also in 
front a slight longitudinal depression outside the costiform elevation. Elytra very 
coarsely sculptured with series of large punctures separated only by small intervals; 
the second and fourth interstices become strongly costate at the tip. Under surface 
coarsely punctate. | 
Five examples were obtained of this interesting insect. It is extremely similar to 
the typical species of the genus, except that E. incilis has apparently thicker antenne, 
formed more after the fashion of Gempylodes.
