530 INSECTA. 



Another species with a depressed body, and in which the 

 third joint of the antennas and the three following' ones are ter- 

 minated by a little bundle of hairs, approaches the Callichromae, 

 with which we formerly arranged it, in its general form and the 

 musky odour it diffuses. It is the A. alpina; Cerambyx alpinus, 

 L. ; Oliv. , lb., 67, IX, 58; cinereous-blue: six blackish spots 

 disposed longitudinally on each elytron, the two middle ones 

 united and forming a band; a spot of the same colour on the 

 anterior part of the thorax; superior part of the joints of the 

 antennae also black. Common in the Alps; it is sometimes 

 taken in the timber yards at Paris. 

 The following Cerambycini have but eleven joints in the antennae. 

 In some, at least in the males, the antennas are long and setaceous, 

 the last joint of the palpi is obconical, the thorax is either almost 

 square and slightly dilated in the middle, or oblong and nearly cy- 

 lindrical it is frequently rugose and tuberculated on the sides. 

 They compose the subgenus 



Cerambyx proper. Cerambyx, Lin. Fab. 



Certain species, with an unequal or rough thorax, usually spinous 

 or tuberculated and dilated on the middle of its sides, with the third, 

 fourth, and fifth joints of the antennae, evidently thicker than the 

 following ones, thickened and rounded at the end; and the latter 

 abruptly longer and thinner, almost cylindrical, forming, with the 

 preceding ones, an abrupt transition, have been generically distin- 

 guished by the name of Hamaticerus. The antennae are much longer 

 in the males than in the females. 



C. heros, Fab.; Oliv., lb., I, 1. Length one inch and a half; 

 black; extremity of the elytra brown and prolonged into a small 

 tooth at the suture; thorax extremely rugose and with a pointed 

 or spiniform tubercle on each side; antennae simple. Common 

 in all the warm and temperate parts -of Europe. The larva 

 bores deep holes in the Oak, and is perhaps the Cossus of the 

 ancients. 



A species called the miUtaris by Bonnelli, very similar to the 

 heros, but without the sutural tooth, and with antennae propor- 

 tionally shorter and more knotted, particularly in the female, 

 is found in the departments of the south of France.
