96  PHYTOPHAGA. 
Vertex deeply trisulcate ; interocular space rather strongly produced ; clypeus nigro- 
piceous, prominent, transverse, subpentangular. Antenne robust, longer than the head 
and thorax, scarcely thickened towards the apex; joints cylindrical. ‘Thorax trans- 
verse ; sides obliquely converging from the base to the apex, distinctly angulate ; upper 
surface transversely convex, flattened on the hinder disc, coarsely and strongly punc- 
tured ; a subcallose, nearly impunctate, vitta on either side, obscure fulvous. Scutellum 
transverse, its apex truncate. Elytra oblong, parallel on the sides, rounded at the apex ; 
lateral margin distinctly, the apical one more strongly, serrulate; each elytron with 
eight regular rows of punctures, the second, fourth, and sixth interspaces, together 
with the suture, costate.

Vertex deeply trisulcate; interocular space produced. Antenne scarcely equal to 
the head and thorax in length, robust; joints short, cylindrical, the seventh and four 
following ones forming an ill-defined club; apical joint truncate. Thorax transverse ; 
sides converging from the base to the apex, obsoletely angulate, the exterior angle armed 
with a very short lateral tooth ; upper surface transversely convex, transversely flattened 
on the hinder disc, coarsely, deeply, and irregularly punctured, the fulvous markings 
nearly impunctate. Scutellum transverse, truncate, nigro-piceous. Elytra oblong, 
parallel, obtusely rounded at the apex; lateral margin distinctly, the apical one more 
strongly, serrulate; each elytron with eight regular rows of large, deeply impressed 
punctures, the second, fourth, and sixth interspaces subcostate; the suture rather 
more strongly elevated. | 
b. Elytra each with eight, at the extreme base with nine, rows of punctures. 
o. Elytra emarginate at the sutural angle. 
6. Uroplata distincta.

verso, lateribus a basi ad apicem convergentibus, medio subangulatis, disci medio rude et crebre punctato ; 
elytris subparallelis, apice rotundatis, ad suturam late subquadratim emarginatis, lateribus minute, margine 
apicali fortius et minus regulariter, serrulatis; utrisque octo-, basi extrema nono-seriato-punctatis ; inter- 
spatiis secundo, quarto sextoque costatis. , .
