Cycurus ANDREWSII. 
Black ; thorax deep greenish blue, heart-shaped, nar- 
rowed behind, and slightly margined at the sides ; ely- 
tra deep blue, faintly tinged with violet, slightly cari- 
nated at the base and sides, and with punctured strie. 
Length, including the mandibles, nine and a half lines. 
Head, blue-black, smooth, obsoletely wrinkled on the 
front, and impunctured. Thorax, heart-shaped, very 
much narrowed and truncated behind, rounded at the 
sides, with a small elevated lateral edge, furrowed in the 
middle, and slightly depressed before the base, which is 
covered with shallow, irregular punctures. Elytra ob- 
long-ovate, quite convex, and very slightly carinated at 
the shoulders and sides ; _ they are marked with fine and 
narrow punctured strie ; but the strie become obsolete 
and the punctures irregular and more dilated, at tip. 
Epipleure greenish black and punctured. Body be- 
neath black. ' Legs black ; tarsi rust-colored. 
Inhabits North Carolina. 
This species has very much the form of the margina- 
tus from Ounalaschka and Oregon, and it still more 
closely resembles, in its proportions, a new species from 
Oregon, which I have described under the’ name of 
cristátus for the Journal of the Academy of Natural 
Sciences of Philadelphia. lt is a much more convex 
species than the marginatus; the thorax is narrower 
behind, with more rounded posterior angles ; the elytra 
are distinctly striated and punctured, the interstitial 
lines are entire and not broken into tubercles, and the _ 
carinated ‘edge is much narrower and not at all more 
conspicuous at the humeral angles than at the sides.
