COLEOPTERA. 121 



as long as the head; their body is long, narrow, and almost linear. 

 The palpi also are more salient. The eyes are entire *. 



Sometimes the head is abruptly narrowed immediately behind the 

 eyes. The antennae, inserted near the anterior extremity of their 

 internal emargination, are remote at base. The two eminences from 

 which they rise are almost confounded in one plane. The thorax is 

 almost always smooth or without lateral tubercles. They are the 



Leptura, Dej. DahL, 



Or Leptura properly so called. 



In some the thorax is almost plane above, and trapezoidal or coni- 

 cal. Of this number are 



L. armata, Gyll.; L. calcarata. Fab., the male; L.subspinosa, 

 Ejusd., the female; which is very common in summer in the 

 woods, on the flowers of the Bramble. The body is elongated 

 and black, the elytra are yellow with four transverse black lines, 

 the anterior of which is formed by points. The antennae are 

 picked in with black and yellow. The posterior tibiae of the 

 male are armed with two teeth. 



L. nigra, L.; Oliv., Col., 73, III, 36. Black and glossy, with 

 a red abdomen. 

 In others, the thorax is much more elevated and rounded, or 

 almost globular. Such is 



L. tomentosa. Fab.; Oliv., lb., II, 13. Black, with a yellowish 

 pubescence on the thorax; elytra of the same colour, and the 

 extremity black and truncated. Very common in the environs 

 of Paris f. 



FAMILY V. 



EUPODA. 



Our fifth family of the tetramerous Coleoptera is composed of In- 

 sects, the first of which so closely approach the last Longicornes that 

 they were confounded both by Linnaeus and Geoffroy, and the last 

 are so closely allied to the Chrysomelae, the type of the following 

 family, that the first of those naturalists places them in that genus. 

 The organs of manducation present the same affinities; thus in the 

 first, the ligula is membraneous, bifid, or bilobate, as in the Longi- 

 cornes; their maxillae also greatly resemble those of these latter; but
