112 PHYTOPHAGA. 
acute, the two lower joints ovate, short, equal, very slightly thickened, the third equal in 
length to the preceding two united. Thorax broader than long; sides nearly straight, 
converging from base to apex ; upper surface transversely convex, the hinder disc faintly 
excavated on either side the medial line, coarsely and deeply punctured; a broad sub- 
torulose vitta on either side near the lateral margin less closely punctured. Elytra 
parallel, very slightly dilated at the obsolete hinder angle; apex rounded; apical 
margin dilated, broadly emarginate at the suture; sides finely, the apex rather more 
strongly, serrulate; each elytron with ten, at the extreme base with eleven, rows of 
deep punctures; the second and fourth interspaces, together with the suture, moderately 
costate, the eighth interspace obsoletely elevated. | 
33. Uroplata westwoodi. (Tab. IV. fig. 17.) 
Elongata, parallela, nigra; subtus nitida, thorace, abdominis limbo angusto femoribusque subtus, flavis; supra 
subopaca ; capite sordide fulvo, vertice antennisque nigris; thorace transverso, lateribus angulatis ; 
crebre punctato, sordide fulvo, lateribus vittaque lata discoidali, hoc sepe ante apicem abbreviata, nigris ; 
scutello nigro; elytris parallelis, lateribus obsolete serrulatis; apice rotundatis, fortius sed minus regu- 
lariter serratis, utrisque decem-, basi extrema undecim-seriato-punctatis, interspatio secundo valde costato, 
interspatiis quarto apice, sexto basi, nec non octavo toto, minus distincte elevatis ; callo humerali lateraliter 
paullo producto, acuto ; nigris, vitta laterali, a basi ad angulum posticum extensa, basi nigro maculata, 
maculaque apicali sordide fulvis.

Vertex smooth, opaque; interocular space produced, its apex angulate. Antenne 
rather more than one third the length of the body, filiform, very slightly thickened 
towards the apex; joints cylindrical. Thorax transverse ; sides straight and parallel 
to the middle, thence obliquely converging to the apex, the apical angle not produced ; 
upper surface transversely convex, broadly depressed on the hinder disc, opaque, closely 
punctured ; obscure fulvous, the lateral margin, a broad discoidal vitta (the latter some- 
times abbreviated anteriorly) together with the apical margin, black. Scutellum black. 
Elytra parallel, rounded at the apex; the lateral margin obsoletely serrulate, the apical 
one rather coarsely serrate, the apical teeth sometimes placed at irregular intervals along 
the margin ; each elytron with ten, at the extreme base with eleven, rows of punctures ; 
the second interspace strongly costate, the fourth interspace at its apex, the sixth at the 
base, and the entire eighth, less strongly raised. | , 
This species is very closely allied to U. infuscata, Chapuis, the chief difference being 
in the rather broader and less strongly punctured thorax in the latter insect.. U. west- 
woodi varies greatly in the extent of the fulvous colouring ; in some specimens from — 
Colombia the marginal vitta on the elytron is submarginal for nearly the whole of its ) 
course, and is continued onwards to join the apical spot; in others the fulvous coloration 
covers to a greater or lesser extent the outer disc. SO
