CoccoTORUS PRINCIPALIS. 
Pl. n, Fig. 18. 
Head fully half as high again as long, very full, closely punctate ex- 
cept beneath, where it is transversely striate ; eyes pretty large, transversely 
oval, about as long as the width of the beak; this is slightly longer than 
the thorax, gently arcuate, rather stout and equal, finely punctate. Thorax 
hardly tapering, full and rounded, half as high again as long, very closely 
punctate with moderately coarse punctures, which show a slight tendency 
to vermiculate coalescence in various directions. Elytra tolerably equal, 
more than twice as long as broad, punctato-striate, the interspaces sparsely 
and shallowly punctate and with signs of transverse rugule.
