UROPLATA. 97 
Hab. Mexico (var. A.), Jalapa (Hége, type); GuateMaLa, Tamahu, Chiacam in 
Vera Paz (Champion). 
Vertex and front deeply sulcate; clypeus transverse, produced, its upper edge sub- 
angulate. Antenne nearly half the length of the body, slightly thickened towards the 
apex; joints subcylindrical. Thorax transverse, subconic; sides converging from base 
to apex, obsoletely angulate; disc coarsely and closely punctured, a broad submarginal 
torulose, impunctate vitta on either side, fulvous. Elytra subparallel, very slightly 
‘increasing in width towards the apex; the latter rounded, broadly subquadrate-emar- 
ginate at the suture, the lateral margin finely, the apical one more strongly and some- 
what irregularly, serrulate ; each elytron with eight, at the extreme base with nine, 
regular rows of punctures; the second, fourth, and sixth interspaces costate, the last 
less distinctly raised than the two others. 
Very similar in the emargination of the elytra to U. explanata, but the form of the 
antenne is entirely different ; the elytra are less dilated at the apex, their upper surface 
with an additional row of punctures at the base. 
00. Apices of the elytra entire. 
7. Uroplata chevrolati. 
Uroplata (Pentispa) chevrolati, Chapuis,. Ann. Soc. Ent. Belg. xx. p. 21 (1877 y. 
Anguste oblonga, dorso deplanata, nigra; subtus nitida, supra subnitida; clypeo piceo; thorace transverso, 
conico, lateribus bisinuatis, transversim convexo, disco postico leviter depresso, rude et crebre foveolato- 
punctato, utrinque vitta subtorulosa, fulva ornato; elytris oblongis, fere parallelis, apice obtusis, minute 
serrulatis; utrisque octo-, basi extrema nono-seriato-punctatis, interspatiis secundo, quarto et sexto, nec 
non sutura, costatis ; plaga humerali, retrorsum plus minusve extensa, fulva instructis.

feet (Champion); Costa Rica (Van Patten).—CoLoMBIa. 
‘Head tinged with neous; vertex and front impressed with three to five longitudinal 
grooves ; clypeus produced, transverse, trigonate. Antenne rather longer than the head 
and thorax, slightly thickened towards the apex ; joints cylindrical, the club very slightly 
compressed. Thorax transverse ; sides converging from base to apex, bisinuate ; upper 
surface transversely convex, transversely excavated on the hinder disc, closely and strongly 
punctured ; a subtorulose vitta on either side, rather less closely punctured than the disc, 
fulvous. Elytra broader than the thorax, parallel on the sides, obtusely rounded at the 
apex; lateral margin finely, the apical one rather more distinctly, serrulate; each elytron 
with eight, at the extreme base with nine*, rows of punctures; the suture, together 
with the second, fourth, and sixth interspaces, moderately costate. 
* In this species the short sutural stria is represented only by one or two punctures.
