common Brazilian Malacoscylus cirratus. ‘The species further 
differs in the crown having a single central black stripe, 
and not two separate vitta. The colour of the fore part of 
the head varies, being sometimes wholly fulvous and some- 
times more or less clouded with dusky or black.

Intermediate in generic structure between Zhemistonoe and 
Malacoscylus, but nearer the former on account of its elongate 
shape and the distinct, though moderate, rounded expansion 
of the elytra towards their apices. The third antennal joint, 
viewed sideways, appears slender and fringed beneath only 
with fine and long hairs; but viewed from above it is thicker 
than the fourth and densely pilose on each side, as in the 
larger species of Themistonoe.

Agrees with L. Beltit in the wide dilatation of the elytra, 
which is carried to a greater extent in these species than in Z. » 
simulatrix and L. togata. It differs, however, in colours, the 
elytra being violet-black (more violet in the apical part) and 
traversed by two tawny-ochreous belts of equal width, one 
basal and the other median. ‘The sides of the thorax are 
also tawny ochreous, having a broad dorsal vitta (much nar- 
rowed behind) of the black ground-colour; the head is black, 
with a spot between the antennx and one on the occiput on 
each side tawny.
