longitudinal furrow in its hinder half, which is deepened into a 
fovea immediately in front of the base. The elytra are slightly 
wider than the prothorax, are finely wrinkled in a transverse 
direction in front, and bear a number of irregular feebly-defined 
striae which do not interrupt the general puncturation, and the 
interstices between which are in places feebly convex and (in 
most examples) here and there more or less Isevigate. The under- 
side is very sparingly clothed with fine adpressed hairs, and is 
punctured more coarsely than the upper surface. The apical 
ventral segment bears a very peculiar elongate transverse sulcus 
in the hind face of its apex, which is much thickened ; this 
segment is in one sex truncate behind and level ; in the other sex 
it is turned up and rounded behind, and the penultimate segment 
bears at the middle of its apex a short erect blunt spine.

Obscure seneo - cuprea, latera versus plus minus purpureo-

posita) crebre confuse, elytris subtilius, subrugulose punctatis ; his 
apice oblique subemarginato-truncatis. 
The head longitudinally is widely concave, but without any 
distinct impressed line ; it is rather coarsely punctulate in front, 
the puncturation becoming finer and closer hindward. The pro- 
thorax is finely punctured on the anterior part of the disc and its 
puncturation thence becomes coarser and less close hindward and 
outward. [This sculpture of head and prothorax is of the same 
kind as in the preceding species, but is evidently closer through- 
out.] The prothorax is about a quarter again as wide as long and 
something less than half as wide again at the Vjase as in front, its 
sides nearly straight (but distinctly diverging) from the base to 
about the middle whence they converge arcuately to the front ; 
the front angles (as in I>. inc'onstann) are quite obscure owing to 
the lateral margin being obsolete anteriorly, the hind angles strong, 
acute and pointed backward ; the surface bears a longitudinal furrow 
feebly impres.sed, not reaching the front, rather d(iepened in front
