COLEOPTERA. 65 
There the body is usually narrow and elongated, the maxillary 
palpi are terminated by a securiform joint, and the penultimate joint 
of the tarsi, or at least of the four anterior ones, is bilobate. 
Sometimes the antennee are thick and composed of short obconical 
or turbiniform joints. 
In some, as in the two following subgenera, the boby is oval, and 
the thorax transversal or almost isometrical, and becomes widened 
from before posteriorly. 
Direma, Fab.—Xvurra, Payhk. 
Or Dirceea properly so called, where the maxillary palpi are not 
serrated, and their last joint projects more on the inner side than the 
preceding ones. ‘Thé thorax is insensibly lowered on the side. The 
scutellum is very small *. 
Metanprya, fab., 
Where the maxillary palpi are evidently serrated, the extremity of 
the second and third joint being prolonged into a point, and on a 
level with the fourth or the last. The thorax is abruptly depressed 
laterally, near its posterior angles, and the posterior margin is sinu- 
ous. The scutellum is of an ordinary size +. 
In the following subgenus, the body is narrow and almost linear. 
The thorax forms a long square, narrowed posteriorly. 
Hypuuus, Payk.—Dircma, Fab. 
The antennz longer than in the preceding subgenus, slightly per- 
foliate and more separate ; the three last joints of the maxillary palpi 
forming, together, an oval club f. 
Sometimes the antennz are slender, and composed of elongated 
and almost cylindrical joints; the body is long and narrow, and the 
abdomen elongated. 
Serropaupus, Hellw. Payk.—Direma, Fab. 
Where the body is firm, the maxillary palpi are strongly serrated, 
the thorax is at least as long as it is wide, and the four posterior tarsi 
are long; all the joints of the two last are entire or without any ap- 
parent incisures §. 
Conopatpus, Gyll., 
Where the body is soft, the maxillary palpi are but slightly ser- 
rated, the thorax is transversal, and the tarsi moderately elongated ; 
the penultimate joint of the whole number is bilobate ||.
