552 Mr. Waterhoyggeon some South American 
of the elytra; very highly polished, «neous where the 
light falls upon the surface, but almost black in the 
shade, with purple-coppery tints slightly visible in certain 
lights. Front of the head and the clypeus finely and 
closely rugulose; the clypeus rather acuminate and 
notched at the slightly reflexed apex. Thorax convex, 
moderately thickly but extremely delicately punctured, 
except within the incrassated margin, where it is closely 
rugulose, straight at the sides to rather in front of the 
middle, then obliquely narrowed to the front. Elytra 
impressed at the sides below the shoulders ; at-first sight 
appearing without punctuation, but on close examination 
some extremely fine punctures may be seen ; the margin 
below the shoulder is incrassate, and there is a finely 
rugulose space above the margin; all the apex below the 
callus is densely and finely rugulose, the rugulose surface 
continued (gradually becoming narrower) round the side 
to about the middle, leaving the extreme margin at the 
side smoother. The sternal process is very short and 
small, the apex turned away from the coxe. Body 
beneath hairy. Pygidium densely rugulose, more finely 
so at the base than at the apex, beset with yellowish 
hair. The larger claw to all the tarsi bifid.

3. Chlorota bidentata, n. s. 
Oblonga, antice paulo angustata, eneo-lucens, muta- 
bilis, nitidissima ; elytrorum marginibus apiceque sub- 
tiliter rugulosis. Long. 9 lin. 
Closely allied to C. vitrina, but shorter, less straight at 
the sides of the elytra. The clypeus is a little less nar- 
rowed in front, and less acutely bidentate at the apex. 
The rugulose space within the lateral margin of the 
thorax is a little wider (} mm. wide). The very finely 
rugulose surface of the apex (which is tinted with brown) 
is more extended, and is continued like a broad band all 
round the sides to the shoulder, leaving the incrassated 
margin below the shoulder, and a very short ridge on the 
side about the middle, smooth. The apex of the sternal 
process is turned up, i.¢., away from the anterior coxe, 
asin C. vitrina.
