108 PHYTOPHAGA. 
obtusely truncate at the apex, the posterior angle produced laterally into a short 
triangular plate; each elytron with eight regular rows of punctures, .the second, fourth, 
and sixth interspaces costate, the apex of the third costa extending over the surface of 
the dilated posterior angle; a narrow submarginal vitta extending from base to apex 
_and running along the edge of the cristate humeral callus, together with a narrow 
subapical band, rufo-piceous; the dilated posterior angle dark piceous; in the single 
specimen before me there is a faint trace of a small subapical black spot. 
Similar in form to U. elevata, but less than half the size, its antenne unicolorous. 
26. Uroplata centromaculata. 
Uroplata (Octhispa) centromaculata, Chapuis, Ann. Soc. Ent. Belg. xx. p. 24 (1877) *. 
Hab. Mexico!, Tuxtla (Sallé); Guatemata, Duefias (Champion). 
This species, which is well although briefly described by Dr. Chapuis, is much 
shorter and broader than U. elevata and U. buqueti; its antenne are shorter, being 
scarcely longer than the head and thorax; the thorax is more transverse ; the elytra are 
oblong-quadrate and the humeral callus is more strongly cristate. 
oo. Humeral callus not elevate-cristate. 
27. Uroplata hematopyga. (Tab. IV. fig. 18.) 
Anguste subcuneiformis, dorso depressa; subtus nitida, supra subopaca, rufa, capitis vertice nigro; antennis 
rigidis, ad apicem paullo incrassatis; thorace transverso, rude punctato, plus minusve piceo tincto; 
elytris ante medium parallelis, apicem versus paullo ampliatis, apice obtuse rotundatis, angulo postico 
lateraliter paullo producto, obtuso ; lateribus minute, margine apicali magis distincte, serrulatis; utrisque 
octo-seriato-punctatis, interspatiis secundo, quarto sextoque, nec non sutura, costatis ; nigro-piceis, apice 
maculisque parvis discoidalibus rufis. . 
Long. 23-3 lin. 
Hab. Mexico, Cordova (Hége); Panama, Bugaba 800 to 1500 feet (Champion). 
Vertex and front plane, the latter carinate on the medial line. Antenne slightly 
longer than the head and thorax, robust, thickened towards the apex ; joints cylindrical. 
Thorax nearly one half broader than long; sides converging from the base to the apex, 
sinuate near the base and again just before the apex; subcylindrical above, transversely 
excavated on the hinder disc, coarsely and deeply foveolate-punctate ; more or less © 
stained with piceous, in some specimens this colour covering almost the entire surface. 
Elytra parallel from the base to beyond the middle, slightly dilated posteriorly, obtusely 
rounded at the apex, the posterior angle distinctly laterally produced, obtusely rounded ; 
lateral margin finely, the apical border more strongly, serrulate; each elytron with 
eight regular rows of punctures, the suture, together with the second, fourth, and sixth 
‘interspaces, costate. 
The specimen from Bugaba is rather smaller, more darkly coloured, and the elytra 
have a distinct metallic violaceous tint ; the front is also less distinctly carinate.
