542 CLASS INSECTA. 



PiMELiA, Tenehrio, Lin. 



These heteromera belong to the countries which surround 

 the Mediterranean, south-western Asia, and Africa. They are 

 not, or at least have not yet been found, in the East Indies. 



Some species, generally more elongated, have the mentum 

 exposed, the antennae slightly and insensibly thicker toward 

 the end ; the last three articulations do by no means compose 

 a knob, divided into two portions of equal thickness, the 

 last of which formed by the tenth and the last articulation 

 confounded together. 



In some among them the abdomen is in proportion larger 

 and more voluminous, the tarsi are relatively less elon- 

 gated, the fore-legs are in the form of a reversed triangle, 

 elongated, with the outer angle of their extremity prolonged, 

 the spurs strong, and tarsi short. 



M. Fischer (Entom. de la Russ.) has divided them into 

 three genera, Pimelia, Platyope and Diesia, but whose cha- 

 racters, founded only on the more or less projection of the 

 last articulation of the antennae, and the indentures of the fore- 

 legs do not appear to us sufficiently decided. The eleventh 

 and last articulation of the antennae is more distinct in the 

 last genus. The fore-legs are very much indented on the 

 outside in Platyope. Their corslet is squared transversely, 

 with the base of the elytra straight, and the outer angles or 

 shoulders a little advanced. With the Pimelia, properly so 

 called, of this author, or those whose eleventh and last arti- 

 culation of the antennae are united, or nearly confounded, 

 with the preceding, or the corslet nearly semilunar and con- 

 vex, and whose abdomen is nearly ovoid or globular, is 

 arranged a species, very common on the shores of the Medi- 

 terranean {P. 2-punctator, Fab. Oliv. Col. III. 59. 1. 1.). It 

 is about eight lines long, of a shining black. Its corslet is 

 shagreen, with two large deep points in the middle, united
