Truncus. Thorax transverso-sub-quadratus, longitudine pauló latior, basi apiceque 
latitudine subzequalis, _ Coleoptra thorace vix latiora sed plus dupló longiora, stris. 
obsoletissimis a basi usque ad apicem decurrentibus, apice rotundata sed magis 
acuta quàm in precedente. Pedes rufo-ferruginei ; interdum nigro-picei, tibiis 
tarsisque rufo-ferrugineis; in mare femoribus anticis apice incrassatis, tarsis 
mediis articulo primo dilatato. 
If "e preceding species can be best referred to Paykull's 
Catops sericeus, there is equal reason to believe that the present 
is his C. Morio, which he characterizes as more oblong than that, 
its thorax narrower, and nearly as broad before as behind ; the 
antenne with a minute eighth joint; the elytra less convex, 
* thorace plus quam dimidio longiora ;" the thighs fuscous; and, 
lastly, almost one half less in size. 
The synonyms quoted from Illiger, Latreille, and Panzer are 
liable to little or no doubt. The magnified figure which the lat- 
ter has given of the head and antennz of his Helops tristis aptly 
represents those parts in this species, the fore part of the head 
being shorter than is common in this family, just as he has 
figured it. I refer to Fabricius on the authority of Paykull. His 
description of C. Morio suits neither this species nor any other of 
the genus: for I know not one with wholly black antenne.
