NEOXIPHISTES, gen. nov. 
THIS genus possesses all the characters of Xiphistes (found 
in both the Oriental and Ethiopian Regions), but differing 
in the length of the posterior pronotal process, which is very 
long, considerably passing the apex of the tegmina. In 
Xiphistes it about reaches the apex of the interior margin 
of the tegmina. 
Type. Neoxiphistes lagosensis, Dist. 
Neoxiphistes lagosensis, sp. n. 
Piceous; the central pronotal ridge, apices of the pronotal 
angles, and about apical half of the posterior pronotal process, 
castaneous ; tegmina subhyaline with the venation black; pronotum 
finely rugose, centrally strongly longitudinally carinate, anterior 
angles robust, tricarinate, obliquely divergent, about as long as 
breadth of pronotum at their bases, beyond the central longitudinal 
carination are shorter and less pronounced carinations proceeding 
from the outer and inner basal margins of the produced angles: the 
posterior pronotal process is nearly as long as the whole body 
including the tegmina, and extends considerably beyond the tegminal 
apices, it is also tricarinate or three-cornered; legs brownish- 
ochraceous, femora (excluding apices), and the tarsal claws, black.
