COLEOPTERA. 



joint of the antennae cylindrical, while that of Calosoma is 

 greatly compressed. C. serratus Say (Fig. 363 ; , pupa of the 

 European C. aurouitens) is black bordered with 

 purple. The closely allied species of Cyclirus, of 

 rich purple and blue tints, differ in the longer head, 

 the deeply bilobate labrum, and in having four of 

 the antennal joints smooth, with thickly striated 

 elytra. (We figure some unknown larva? of this 

 family which are allied to 

 C'arabus ; Fig. 364, natural 

 size ; Fig. 365, a little en- 

 larged ; a, mouth parts ; 6, 

 end of the body, and Fig. 

 366. a larva apparently of the 

 KI,U. :;m. same genus.) Pasimachus 

 Lee. (Fig. 367) has been 



found, according to Walsh, to prey on 

 the Doryphora. or Potato beetle. 



The o-enus Scarites and its allies have 



the anterior toothed palmate tibia 1 more 

 or less produced at the apex, with a 

 pedunculate abdomen. In Scar- 

 ites and Pasimachus the basal 

 joint of the antenna is very long ; 

 the former having the maxilhv 

 rounded at the tip, and the tho- 

 rax rounded behind, while in 

 \ Pasimachus, the thorax is dis- 

 tinctly angulated, and the max- 

 illa* are hooked. In Cli-vina the basal joint of the an- Fi - :!li(i - 

 tenure is short, the mandibles flat and acute, and the clypeus 

 is not emarginate. 



In Harpalus and allies the epimera of the mesotho- 

 rax do not extend to the coxa 1 , and the mesosternum 

 is large, widely separating the middle coxa\ Of this 

 group BmcMnus (B. fumans Fabr. Fig. 368), the 

 Bombardier beetle, with its narrow head and cordate 

 Fig. ;?68. prothorax, is remarkable for discharging with quite 

 an explosion from its anal glands a pungent fluid, probably
