Oregon, col. M'Call. Sufficiently distinct from any other species 
herein described, and apparently more nearly related to €. æthiops ; 
the third joint of the antennæ is triangular, as long, but only half 
as wide as the following, which are acutely triangular, but not pro- 
duced at the angle; the eleventh joint is not longer than the tenth, 
not acuminate, but still distinctly constricted. 
10. CORYMBITES MENDAx. Péceo-æneus, elongatus, cinereo-pubes- 
cens, thorace latitudine longiore, convexo, ad apicem utrinque 
transversim vmpresso, lateribus ante medium rotundatis, angulis 
posticis carinatis divergentibus, confertim punctato, subcanaliculato, 
elytris striis punctatis, interstitiis planis rugose punctulatis, an- 
tennis nigris, vix serratis, articulo tertio secundo paulo longiore, 
conjunctis quarto longioribus, pedibus piceis. — Long. 4”, 1.

One specimen, lake Superior : has the appearance of Limonius, 
but che front is not margined anteriorly, and not quadrate: its real 
aflinities are with the two preceding species (1), from which it aif- 
fers by its more convex and coarsely punctured thorax. The elytra 
are somewhat obliquely narrowed posteriorly and more strongly 
margined than in the two preceding. "The first joint of the tarsi is 
not longer than the second. 
11. CorymBites ANGULARIS. Nigro-piceus, valde elongatus, tenuiter 
pubescens, thorace latitudine fere sesqui longiore, antice non an- 
gustato, parum convexo, lateribus fere rectis, apice submarginato, 
angulis anticis rufescentibus latius marginatis, angulis posticis 
(4) C. insidiosus et falsificus.
