16 PHYTOPHAGA. 
sides straight and parallel, slightly converging at the apex, anterior angle subacute, the 
hinder one acute; anterior margin sinuate on either side ; surface impressed with round 
punctures, which are irregularly scattered over the hinder two thirds of the disc, but 
are nearly obsolete on the sides and at the apex; flavous; a large subquadrate patch, 
attached to the basal margin and covering the posterior two thirds of the disc, but not 
extending to the sides, black; outer limb also narrowly edged with black. Elytra | 
narrowly oblong, parallel, obtusely rounded at the apex, regularly punctate-striate ; 
flavous, a basal patch rufo-testaceous ; an entire sutural vitta, broad at its base, but 
gradually narrowed towards its apex, together with another on each elytron, discoidal, 
abbreviated at the base but extending downwards nearly to the apex, where it incurves 
and often joins the sutural vitta, black.

Head closely punctured. Antenne filiform, joints cylindrical, the first slightly 
thickened, rather longer than the second, about equal in length to the third. Thorax 
subquadrate; sides straight and parallel, scarcely converging at the extreme apex, 
anterior angle produced, subacute; disc deeply but not very closely impressed with 
large round punctures. Scutellum rather longer than broad. Elytra much broader 
than the thorax, elongate, parallel; apices rounded, slightly sinuate conjointly at the 
sutural angle ; above moderately convex, slightly flattened on the anterior disc; strongly 
punctate-striate ; flavous; with three broad black vitte, the medial one of which is 
common, entire, slightly dilated below the scutellum and contracted just before reaching 
the sutural angle; the others, one on each elytron, commence below the humeral callus, 
and, after extending the whole length of the disc, incurve to unite with the sutural line. 
Much narrower and more elongate than the preceding species. 
21. Cephaloleia semivittata. 
Elongata, nitida, subtus picea ; pedibus abdomineque fulvis, hoc piceo tincto; pleuris fortiter punctatis ; supra 
nigra; thorace subquadrato, lateribus rectis; subcrebre fortiter punctato; elytris fortiter punctato- 
striatis, fulvis, vitta suturali communi integra, pone scutellum paullo dilatata, alteraque discoidali a medio 
ad apicem extensa, apice cum linea suturali connexa, nigris. 
Mas. Abdominis segmento anali late transversim emarginato, medio sinuato. 
Fem. Abdominis segmento anali apice utrinque sinuato.
