the western and southern parts uf Asia, and the south of Europe and 
Africa *. 
Other Pimeliarize, terminating the subdivision of those in which 
the labrum is not received into a deep emargination of the anterior 
border of the head, and in which this last part of the body is neither 
truncated before nor narrowed behind, are distinguished from the 
preceding by the following characters. The middle of the anterior 
margin of this part projects in the manner of an angle or tooth. 
The labrum does not appear when the mandibles are closed, or but 
very little. The thorax is sometimes trapezoidal, almost as long as 
it is broad, and at others almost orbicular or nearly semicircular. 
The antenne are filiform, and the eleventh and last joint is always 
very distinct from the preceding one. ‘The mentum is incased infe- 
riorly and covers the base of the maxille. The presternum is 
slightly prolonged into a point in several. These Insects, like those 
of the two following subdivisions, are exclusively peculiar to the hot 
and western countries of the eastern continent. 
Heeeter, Lat. 
The thorax forming a trapezium, almost as wide at the posterior 
margin as the base of the elytra, and in contact with it throughout ; 
the last joint of the antennze somewhat smaller than the preceding 
one f. 
TentyriA, Lat.—Axis, Fab. 
The thorax almost orbicular, sometimes narrower than the abdo- 
men, and at others of equal width, but rounded at the posterior an- 
gles, and leaving an hiatus between them and the base of the elytra. 
The last joint of the antenne is at least as large as the preceding 
one f. 
Other Pimeliariz are removed from the preceding ones by the 
form of their head and thorax. The first is a kind of square, more 
or less narrowed behind, and the middle of its anterior edge presents 
an emargination which receives the labrum. ‘The dilatation of the 
lateral margin covering the base of the antennee is greater, and pro- 
longed to the anterior edge. The latter organs are always composed 
of eleven very distinct joints, almost cylindrical, the last few ex- 
cepted, with the third very long. The middle of the outer side of the 
mandibles is deeply excavated, and the inferior sides of the head, 
forming the lateral casing or frame of the maxillsze and mentum, ter- 
minate in a point, or in the manner of a tooth. The thorax is in the 
form of a truncated heart, and well emarginated before in most of 
them. These Pimeliariz comprise a great portion of the genus
