surface and sides scantily punctured towards the base, brown, 
with many black and ill-defined longitudinal streaks, besides a 
broad indistinct ashy streak beginning at the shoulder, bending 
towards the suture, and then continuing, parallel to the suture, 
to the apex ; the mode of coloration gives to the insect a striking- 
resemblance to a small chip of bark. Body beneath dusky, with 
scant ashy pile. Legs reddish, ringed with ashy. 
$ Ovipositor projecting very slightly beyond the tips of the 
elytra ; dorsal plate obtusely rounded at the tip, ventral trun- 
cated.

E. elongatus, subangustatus, fulvo-griseus, nigro vittatus et macu-

Head blackish, orbits of eyes fulvous. Antennse black or dull 
red, third to sixth joints ringed at the base with grey. Thorax 
not much broader than the head ; lateral tubercles small, placed 
a little behind the middle; disk slightly uneven, ashy tawny, 
with six black vittse, the two outermost of which are below the 
lateral tubercles. Elytra elongate, gradually narrowed to near 
the apex, thence more abruptly narrowed, apex briefiy and ob- 
tusely truncated ; lateral carinse sharp and smooth, surface faintly 
punctured towards the base, and covered besides with minute 
setiferous punctures, clothed with tawny pile, much spotted and 
patched with black, the apical region on each elytron being- 
occupied by a large clear black spot margined with ashy. Body 
beneath ashy tawny. Legs blackish, with scant tawny clothing ; 
tibise ringed with ashy; tarsi with the two basal joints grey. 
S Coxse and breast densely hairy, as also (in well-developed 
examples) the middle of the abdomen. Terminal abdominal 
segment with ventral plate sharply notched, dorsal moderately 
so. Tore and middle tarsi dilated and fringed with hairs. 
Also found on the banks of the Cupari. M. Bar has since 
met with it in the interior of French Guiana. The species, 
although having an elongated form of body like the Colobothea, 
does not ofier the peculiar facies of that genus, owing to the 
different shape of the apex of the elytra.

With this genus commence the more elongated and narrow 
forms which distinguish the typical Colobotheinse. The elytra
