LEPTURGES.—CARPHONTES. 17ft 
valida, acutissima, retrorsum spectante ; elytris postice convexis, apice rotundatis, dorso pilis erectis non- 
nullis obsitis. 
Long. 12 lin. 
Hab. Guatemaua, San Gerdénimo (Champion). 
The few long soft hairs which spring from the surface of the elytra are of different 
nature from the rigid bristles which are seen in Phrissolaus and Sporetus, and seem not 
to indicate any generic distinction from Lepturges. The species is closely allied to 
L. mixtus, having a similar form of thorax; but the elytra offer no trace of truncature. 
The black lateral mark of the elytra, seen from above, looks like a large semioval spot 
with its convex side approaching the suture; but it consists really of a thick and not 
well-defined flexuous streak, which commences under the humeral angle, runs for a 
space along the epipleura, and then curves towards the disk, terminating beyond the 
middle without reaching again the lateral margin. 
20. Lepturges tigrellus. 
Lepturges tigrellus, Bates, Trans. Ent. Soc. 1878, p. 231. 
Hab. Nicaragua, Chontales (Belt). 
21. Lepturges navicularis. (Tab. XIII. fig. 5*.) 
Lepturges navicularis, Bates, Trans. Ent. Soc. 1872, p. 217°. 
Hab. Mexico, Cordova (Sallé); Nicaragua, Chontales (Bel¢ 1). 
In Mexican specimens the grey longitudinal markings of the elytra are scarcely 
perceptible. 
CARPHONTES. 
Lepturgi proxime affinis, differt mesosterno lato tarsisque posticis brevissimis. Corpus ovatum, convexum, haud 
setosum. Caput breve, infra angustatum ; oculi magni ; frons convexa. Antenne setacex, scapo valde 
elongato, subtus paullo flexuoso, articulo tertio scapo subeequali, 4°-11™ brevioribus, decrescentibus. Thorax 
valde transyersus, spina laterali valida, conica, acuta, paullo ante basin sita; ante spinam valde angus- 
tatus, post spinam modice constrictus ; dorsum convexorum, equale. Hlytra convexa, wequalia, apice 
obtusissime oblique truncata. Pedes breves; femora modice incrassata; tarsorum posticorum articulus 
primus 2° et 3° conjunctim equalis. Prosternum sat latum; mesosternum latum, postice angustatum. 
Abdomen utriusque sexus apice obtusum, 9 nullo modo elongatum. 
A genus formed for the reception of a species having much resemblance in general 
form to Lepturges navicularis, ovalis, and scutellatus, but differing from them and from 
all other species of Lepturges by the wide mesosternum (which is quite as broad as in 
the typical species of Myssodrys) and the short hind tarsi (which are quite as short as in 
Leptostylus and Alcidion). The rounded apical segment of the abdomen, both of the 
ventral and the dorsal plate, distinguish it from Probatius and Oxathres, to which the 
species bears some resemblance in the form of the thorax. 
* The minute but distinct and acute lateral spine of the thorax has been omitted in this figure.
