antennz at its base and before the eyes, which are always entire or 
unemarginate. These Insects forma single genus, that of 
Myctervs. 
Sometimes the antenne are filiform and the snout is not widened at 
the end; the thorax is narrowed before in the form of a truncated 
cone or a trapezium; the ligula is emarginated, and the penultimate 
joint of the tarsi bilobate. They are found on flowers, a habit indi- 
cated by the silky prolongation of the terminal lobe of their maxilla. 
Srenostoma, Lat. Charp—LeErtura, Fab. 
Where the body is narrow, and the thorax in the form of an elon- 
gated truncated cone; the elytra are flexible, narrow, elongated and 
contracted into a point; the antennze are composed of long and cy- 
lindrical joints, and the maxillary palpi are terminated by an almost 
cylindrical joint, hardly thicker than the preceding ones *. 
Mycrervs, Clairv. Oliv. Brucuvs, Ruinomacer, /ab,.—Myuasris, 
Sche ff., 
Or Mycterus properly so called, where the body is ovoid, solid, 
covered by a silky down, and the thorax trapeziform. The abdomen 
is square, long, rounded posteriorly ; the antennz are composed of 
joints, mostly obconical, the complete number of which seems to be 
twelve, the eleventh or last being abruptly narrowed and acuminated, 
and the maxillary palpi are terminated by a large joint in the form of 
a reversed triangle f. 
Sometimes the antennze are terminated by an elongated club 
formed by the last three to five joints; the snout is much flattened, 
with a salient angle on each side before the extremity; the thorax is 
in the form of a truncated heart, narrowed posteriorly; the ligula is 
entire, and so are all the joints of the tarsi. 
These Insects live under the bark of trees, and in a natural order 
seem to approach the Anthribus of Fabricius, who has confounded 
them. The body is depressed, the proboscis slightly pointed before, 
and the tarsi are short. The palpi are thickest at the extremity. 
They form the subgenus 
Rarnosimus, Lat. Ohv.—Curcunio, Lin. De G—Anrtureisus, Fab. 
Designated by Hliger under the denomination of Salpingus. Some 
entomologists have adopted both, but restrict the latter generally to 
species in which the club of the antenne is triarticulated, and apply-
