and sixth joints grey, middle of the terminal joints grey. Tho- 
rax at first sight appearing to be gradually narrowed from base 
to apex; but the base itself is narrowed, and each side has an 
acute projection, pointed backwards, and nearly touching the 
humeral callus; surface with thirteen stripes alternately black 
and tawny, the central (black) stripe with a grey line down its 
middle. Scutellurn black, streaked with grey. Elytra with the 
shoulders not advanced laterally but vertically and forward, so 
that the humeral ridge fits into the narrow space between the 
lateral tubercle and the base of the thorax ; the surface is setose, 
punctured, and grey, with numerous pinkish marks which are 
chiefly collected round the black fascise ; the latter are three in 
number — one, short, before the middle, the second, oblique and 
angular, behind the middle, and the third, quadrate, at the apex ; 
the extreme apex is bordered with grey or pinkish, and is trun- 
cated, with the sutural angle simple, the external produced into 
a long spine. Body beneath greyish, sides with a stripe of 
fulvous tomentum, abdomen with the sides spotted in the middle. 
Legs grey, femora with a pinkish spot on their upper surface ; 
tibiae ringed with grey and black ; tarsi black, with the two 
basal joints grey ; fore tarsi of the male moderately dilated and 
fringed.

Branches ol dead trees, forest, Para. In the colours of the
