100 PHYTOPHAGA. 
nec non sexto ad apicem, minus distincte costatis, plaga basali callum humeralem amplectente fulva in- 
structis ; pedibus elongatis, femoribus intermediis dentibus brevibus nonnullis armatis. 
Long. 33 lin. 
Hab. Panama, Bugaba 800 to 1500 feet (Champion). A single specimen only. 
Head rather strongly produced between the eyes; vertex and front deeply impressed — 
on either side with a longitudinal groove; a small patch on the hinder border of the 
eye, and one on the anterior portion of the front, obscure fulvous. Antenne rigid, half 
the length of the body, compressed, attenuated towards the apex, the latter acute; the 
two lower joints short, moniliform, the third and four following ones carinate. 
Thorax slightly broader than long, conic; sides nearly straight, sinuate immediately 
behind the anterior angle, the latter armed with a subacute oblique tooth. Elytra 
subparallel, rounded at the apex, emarginate at the suture, the apices with several long 
spinous teeth; each elytron with ten, at the base with eleven, regular rows of punc- 
tures, the second, fourth, and eighth interspaces costate; the sixth interspace towards 
its apex, together with the suture, less strongly elevated. » 
oo. Posterior angle of the elytron laterally produced. 
12. Uroplata aterrima. (Tab. IV. fig. 23.) 
Euprionota aterrima, Guér. Icon. du Régne Anim. iii. Texte, p. 278°. 
- Hab. Mexico1, Jalapa (Hoge), Parada, Juquila (Sallé); Guatemata, Capetillo, 
Duefias, Cerro Zunil 4000 feet, Purula (Champion); Nicaragua, Chontales (Janson) ; 
Costa Rica, Cache (Rogers). 
The diagnosis given by Guérin so accurately defines this species, that a detailed 
description is unnecessary. 
B. Vertex and front plane, often impressed on the medial line with a shallow longitu- 
dinal groove ; anterior surface of the front in some species finely carinate. 
a. Elytra each with eight rows of punctures ; posterior angle not laterally 
produced. 
o. Elytra more or less distinctly emarginate at the sutural angle. 
13. Uroplata championi. (Uroplata emarginata, Tab. IV. fig. 11.) 
Chalepus championi, antea, p. 50. 
Hab. Panama, Volcan de Chiriqui 2500 to 4000 feet, Bugaba (Champion). 
Misled by the general resemblance of this insect to certain species of Chalepus, I, 
without sufficiently careful examination, originally placed it in that genus. Quite
