Maris f route eomu valido recurvo punctulato instructa ; pro-

The protborax is a quarter again as wide as long down the 
middle, and evidently (but not much) less than twice as wide at 
the base as in front. The male differs from that of D. Dejeani 
as follows ; the head is larger, the clypeus broader in front and 
truncate, or even very slightly emarginate all across, with its 
angles, though obtuse, not rounded off, and its sides slightly 
concave in outline, its reflexed margin not quite so erect. The 
prothorax is less emarginate in front, and is much less trans- 
verse, the furrow within the anterior margin considerably further 
back and very much stronger leartng a wide space in front of it, 
the anterior concarity veiy much smaller, not reaching back half- 
way to the base, and occupying (transversely) much less than the 
middle third of the segment, its concave surface almost impunc- 
tate except close to the front margin where it is only thinly 
]»unctulatc and not at all rugose ; the prominent hind margin of 
the concavity is proportionally wider than in Dejeani, and has a 
small tubercle in the middle ; the hind margin of the prothorax 
is rather strongly margined except in the middle. The sculpture 
of the elytra is on the same plan, but is altogether feebler and 
less defined. 
In the female the clypeus resembles that of the male in its shape 
anteriorly, but its surface is closely rugose, and its hind margin 
consists of two lines running obliquely backward and meeting in 
the centre in an olffuse angle, the hinder part presenting the 
api»earauce of a triangular lamina laid back (not quite flatly) on 
the surface of the head, the apex of the triangle being the part 
least closely applied to the head. On the prothorax the furrow 
within the anterior margin is as in the male except that it is
