40 INSECTA. 
PimeL1a—TeEnsri0, Lin. 
These Heteromera are proper to the countries situated round the 
basin of the Mediterranean, to western and southern Asia, and to 
Africa. They are not found in India, or at least none have as yet 
been discovered there. 
Some species, usually more elongated, have the mentum exposed, 
and the antennz slightly and insensibly enlarged at the extremity ; 
the three last joints do not form a club, divided into two equal 
portions, the last of which is composed of the tenth and last joint con- 
founded together. 
In some of these, the abdomen is proportionally wider and more 
voluminous, and the legs are less elongated; the anterior tibize are 
in the form of a reversed triangle, elongated, and have the exterior 
angle of their extremity prolonged; the spurs are stout and the tarsi 
short. : 
M. Fischer—Entomog. Russ. Imp.—has divided them into three 
genera, Pimelia, Platyopus, and Diesta, but their characters, being 
only founded on the greater or less projection of the last joint of the 
antenne and the dentations of the anterior tibiz, do not appear to us 
sufficiently determinate. The eleventh and last joint of the antennz 
is most distinct in the Diesize. The anterior tibize are much dentated 
exteriorly in Platyopa, where the thorax forms a transversal square, 
the base of the elytra is straight, and the exterior angles or the 
shoulders slightly project. Among the Pimelia, properly so called of 
this author, or those in which the eleventh and last joint of the an- 
tennz unites, or is almost confounded with the preceding one, where 
the thorax is almost semilunar and convex, and the abdomen nearly 
ovoid or globular, is placed the : 
P. 2-punctata, Fab.; Oliv. III, 59,i,1. Length eight lines ; 
glossy-black ; thorax granulated, with two large punctures in 
the middles, united in some individuals in a transverse line ; ely- 
tra granulated, each with four elevated lines, the lateral carina 
included, not visibly dentated, of which the two inner ones are 
shorter ; suture elevated. Common on the shores of the Mediter- 
ranean. 
The Tenebrio muricatus, L., is a different species—Schcenh., 
Synon. Insect, I, tab. II, 9. 
P.coronata, Oliy., Ib., II, 17. Fifteen lines in length ; black- 
ish; covered with reddish-brown hairs; a range of postericrly 
curved spines on the lateral carina of each elytron. 
M. Payraudeau has discovered in Corsica a new species—Pay- 
raudu—allied to the first, but with a more elongated abdomen 
and more strongly granulated elytra, on which the two inner 
elevated lines are almost effaced. 
_ In other species,—TRacuypeErma, Lat.,—the abdomen is propor- 
tionally narrower and more elongated, and frequently much com- 
pressed laterally; the legs are long, and the tibiz, the anterior ones
