IJody glossv. Mack untlcrncadi, above blue-black. Head a little 

 bronzed ; nose tnmsversely impressed, wrinkled ; frontal inij)rcs.sions large 

 and deep ; prothor .\ with a deci> anterior transverse impression, reaching 

 nearly from side to side, in the centre of which is also a deep punctiform 

 impression, and behind it on each side two others, but \^•rinkled and 

 more shallow : on each side al.>o is a large gibbosity or boss : elytra 

 nearly oblong, with eie\en r(jus of shining bronzed inmctures : at their 

 apex the [)uncture.-i are s( altered, t!ie margins also are bronzed ; epiplenra 

 i)lack ; the tip of the elyrni is very obtuse and almost truncated : legs 

 rufous. This species is ver\ near Ci. viariiius, but it is mvich larger, 

 and is sufhcienil)- distinguished from it by the deep furrow or channel 

 that runs (juite :u nv-s the i)rolhorax. its more prominent bosses, and its 

 impres.sions. In G. i.tiirijius. also, the punctures at the tip of the elytra 

 are not scattered, but mark out a crescent-shaped area : and the apex 

 itself is not so obtuse. I Referred to 6'. bd'calis Aube, bv White.

 Taken in ('anada by Dr. Higsby. Very like the preceding species, but 

 much smaller, the transverse imi)ression of the nose and the frontal 

 inipressions are not so dee]> : that of the prothorax is not so conspiaious. 

 and there arc no lateral bosses ; the elytra are much narrower at the apex, 

 where, as in G. Marinits. a crescent is marked out by punctures.

Nearly related to 6". aoiiu^s, but the whole prone surface of the body, 

 tile epipleura of the elytra, and the legs, are ferruginous ; in which par- 

 ticulars it resembles G. /ineatus ; it is, however, much smaller than that 

 species, the punctures in the ro\\ s are more conspicuous, and the elytra 

 have no bronzed stripes. ["A beautiful species, easily known by its 

 larger size and more brilliant iridescent surface ; in one specimen the 

 under surface is nearly black." — LeConte, /< v. dt. p. 368. Taken in 

 Canada by Mr. Pettit at Grimsby, Ont. ; also on north shore of lake 

 Superior by Agassizs Expedition. New York to L. Superior (LeContc).]

Near the preceding, but larger, punctures c;f the rows larger : breast

 remainder of the underside of the body, piceous : side-covers bron/cd
