middle, its base evidently narrower than its front margin, its 
sides strongly rounded from the front nearly to the base, where 
they become quite straight and parallel, the median line faint and 
abbreviated at both ends, the hind angles sharply rectangular, the 
depressed basal area very coarsely (but not closely) punctured and 
longitudinally strigose, a strong unpunctured curved furrow 
running transversely a little behind the front margin. The 
sculpture of the elytra is very similar to that of G. ohsoletus, 
except that there are six distinct (though lightly impressed) discal 
striae on each, which are more strongly punctured, the punctures 
extending nearly to the apex except in the 6th stria in which they 
cease (or at least become very obscure) a little behind the middle, 
and that a 7th stria is faintly traceable like the 6th in G. ohsoletus. 
A considerably shorter insect than G. punctipennis and ohsoletus, 
more strongly convex than either, and with the sides more rounded, 
the antennae feebler and the thorax quite differently shaped. 
There is a slightly noticeable development of the apical external 
spine of the anterior tibiae.

A very robust species, more convex than G. ohsoletus, with the 
anterior angles of the elytra considerably more prominent and the 
sides much more decidedly rounded ; there is very little difference 
in the head and prothorax except that the latter is somewhat wider 
in front, and the sculpture of the elytra scarcely differs except in 
that the punctures in the stria) are larger and stronger, are placed 
at wider intervals in the rows and scarcely exist behind the front 
half of the elytra. The evident sub-dentiform external prominence
