106 PHYTOPHAGA. 
22. Uroplata limbata. 
Elongata, parallela, dorso deplanata; nitida, rufo-fulva; antennis nigris, thoracis vittis duabus elytrorumque 
limbo exteriori piceo-sneis ; thorace rude punctato; elytris parallelis, apice rotundatis, tenuiter serru- 
latis; utrisque oeto-serinto-punetatis, interspatiis secundo, quarto sextoque modice elevatis. 
Long. 24 lin. 
Hab. MExico, Yucatan (coll. Baly). 
Interocular space very slightly produced. Antenne rather longer than the head and 
thorax, slightly. thickened towards the apex; joints cylindrical, the five upper ones 
forming a very narrow club. Thorax broader than long; sides rounded, nearly straight 
and parallel behind the middle; upper surface transversely convex, excavated on the 
hinder disc, coarsely and closely punctured, a submarginal vitta on either side piceo- 
zneous. Elytra rather broader than the thorax, parallel, rounded at the apex, the 
outer margin serrulate ; each elytron with eight regular rows of punctures, the second, 
fourth, and sixth interspaces moderately costate ; outer limb broadly piceo-zneous, the 
eeneous tint (in the single specimen before me) gradually lost towards the apex of the 
elytron. 
23. Uroplata belti. 
Anguste cuneiformis, dorso depressa ; subtus nigra, nitida, pectoris medio femoribusque basi fulvis; supra sub- 
opaca, fulva; capite inter oculos modice producto, vertice antennisque nigris, ore nigro-piceo; thorace 
transverso ; lateribus pone medium fere rectis, ante medium rotundatis, et ad apicem convergentibus ; disco 
fortiter et crebre punctato, lateribus vittaque lata discoidali nigris ; scutello nigro; elytris apicem versus 
ampliatis, apice regulariter rotundatis, minute serrulatis, dorso depressis ; utrisque octo-seriato-punctatis ; 
dimidio postico vittaque communi suturali, nigris. 
Long. 34 lin. 
Hab. Nicaraeva, Chontales (Belt). A single specimen. 
Front plane, opaque. Antenne nearly half the length of the body ; third joint equal 
in length to the basal two united, slightly compressed, the fourth, fifth, and seventh equal 
to each other in length, the sixth rather shorter; club not more dilated than the preceding 
joints. Thorax about one half broader than long; sides nearly straight and parallel 
from the base to the middle, thence rounded and converging to the apex, the anterior 
angle armed with a subacute tooth ; transversely convex, strongly and deeply punctured ; 
a narrow lateral stripe, abbreviated at the extreme apex, together with a broader medial 
vitta, black. Elytra rather broadly dilated posteriorly, broadly rounded at the apex, 
finely serrulate, the posterior angle obsolete; each elytron with eight regular rows of 
punctures, the second, fourth, and sixth interspaces costate.
