the last mentioned from Mexico, the other two from Rio Janeiro. 
C. Schmidtii * of French collections (Brazil) from the very slight, 
if any, narrowing of the thorax near the base, seems to stand 
on the confines of subsections a and h. 
b. Thorax widest at the basal angles, gradually narrowed thence to 
the apex. 
1 1 . Colobothea pimpl( 2 a, n. sp. 
C. minus elongata et attenuata, cinereo- vel griseo-fulva ; capite 
fusco, vertice lineis duabus divergentibus cinereo-fulvis ; thorace 
vittis septem fuscis, quarum una mediana latiore ; elytris griseis, 
fusco irroratis, cinereo-fulvo maculatis, fasciis tribus (apud suturam 
interruptis) fuscis, apice sinuato-truncatis, angulis interioribus 
prominulis, exterioribus spiniformibus. Long. 4|^-5 lin. S $ . 
Head dingy brown, forehead streaked with tawny, vertex with 
two fine tawny lines diverging on the occiput. Antennae black 
or reddish, fourth, sixth, eighth, and tenth joints with a whitish 
ring. Thorax depressed at the base, ashy or tawny, with a broad 
central vitta, and, on each side, three narrower vittae, purplish 
brown. Elytra moderately elongated, apex sinuate-truncate, 
with exterior angles produced into spines, and sutural angles 
dentiform; surface grey, minutely speckled with dusky and 
sprinkled with larger tawny (most often rounded) spots : each 
side has three transverse-quadrate purplish-brown spots or fasciae, 
which do not reach the suture, the apex edged with tawny. 
Body beneath clothed with tawny-ashy pile ; abdomen spotted 
on the sides with black. Legs reddish, spotted with ashy. 
Terminal abdominal segment rather more tapering in the 
female than in the male ; dorsal plate notched in both sexes ; 
ventral plate terminating in spines in the male, angles simply 
acute in the female. Fore tarsi in the male moderately dilated, 
fringed with long hairs. 
Branches of felled trees : Para, Obydos, and banks of the 
Tapajos. Also found at Cayenne. I have seen it, in French 
collections, under the name of C. sexlineata (Reiche, MS.) — a 
name which I have not adopte^d, as the thorax has seven lines, 
and not six.

cinereo macula trigona nigra. Antennae nigrae, articulis basi griseis.

Elytra grisea, nigro punctata, maculis confluentibus ochraceo-cinereis 
conspersa, maculis majoribus vel fasciis tribus nigris, una (interdum 
obsoleta) ante medium, altera majore angulata pone medium, tertiaque
