64 PHYTOPHAGA. 
slightly broader than long; sides converging from base to apex, obsoletely angulate ; 
above subcylindrical, transversely depressed on the hinder disc, closely and coarsely 
punctured ; lateral margin narrowly edged with piceous. Elytra oblong, parallel ; apices 
conjointly, obtusely rounded ; margin minutely serrulate ; upper surface convex on the 
sides and at the apex, slightly flattened along the suture; each elytron with ten, 
about the middle disc with nine, at the extreme base with eleven, rows of deeply 
impressed punctures; the second, fourth, and eighth interspaces (the basal third of the 
last excepted), together with the sixth at base and apex, costate, the suture also 
elevated. | 
This species differs, according to Dr. Horn, from the smaller forms of C. (Odontota) 
rubra in having the thorax much less dilated posteriorly, and in the absence of the rather 
abrupt expansion of the apices of the elytra; the elytral coste are also less elevated.

Vertex and front bisulcate ; interocular space moderately produced. Antenne more 
than one third the length of the body, filiform, slightly thickened towards the apex. 
Thorax transverse; sides nearly straight and parallel from the base to the middle, 
thence obliquely converging and slightly rounded to the apex; above subcylindrical, 
transversely excavated on the hinder disc, deeply and somewhat closely punctured. 
Elytra parallel, obsoletely constricted in the middle, serrulate, regularly rounded at the 
apex ; each elytron with ten, about the middle with eight, rows of punctures; second, 
fourth, and eighth interspaces costate, the suture also elevated.

elevata.
