and the punctures larger, more shallow and irregular. 
Epipleure violet, punctured. Body beneath, antenne 
and legs black ; tars? piceous. 
Inhabits Ohio and Indiana. | 
This noble species.is readily distit@Mishied from. the : 
elevatus by its superior magnitude, by its shorter, thicker, | 
and more convex form, and by its differently shaped | 
thorax, which is more narrow before, and much more 
contracted behind; the lateral margins are oblique and ` 
not so much elevated, and the edge is much thicker and 
more rounded; the posterior angles are not so much .- 
produced behind, and are not so acute; the disk is not 
so much a Ls the posterior transverse inden- 
tation is very much deeper. The elytra are bronzed, 
but are destitute of the ‘brigh .cupreous tinge of the 
elevdtus ; the striæ are deeper and. more distinct ; the 
interstitial lines are wider, more elevated, moi 
rand perfectly smooth ; and, lastly, the me carna is 4 
more narrow, and not so much elevated, particularly 
at the humeral angles, which are also more obtusely 
rounded. 
Knoch has described and figured the elevàtus as 
having the thorax equally broad, * equaliter. latus ; D 
and indeed it is nearly as wide at the base as in the 
middle, in which respect it differs essentially from T 
heros; "The carina at the shoulders of the elytra, in 
elevátus, is remarkably wide and elevated, which g ves 
a great prominence to the humeral angles. Fabriciu s F. 
the first describer of the elevdtus and of another species, s 
* 
which he calls Cvcunvs unicolor, says, of the latter, s 
that it is of the same form as the elevàtus, is larger, but ^ Y 
closely allied, and that perhaps it is a mere fariety of *
