ed elevated lines on each ; thorax almost cylindrical. The male is 

 distinguished from the female by the eyes being more approxi- 

 mated and by the antennae, the last joint of which is as long as 

 the four preceding ones united. 4 lines long. Inhabits Europe.

TRIBE II. PYROCHROIDES. 



Hooks of the tarsi simple, without division or appendages; body 

 oblong, straight, depressed, with the thorax round or trian- 

 gular ; elytra as long as the abdomen, of the same breadth or 

 broader, and rounded at the end ; maxillary palpi slightly 

 serrated, the labial filiform; antennas flabelliform or pectinated. 

 Gen. PYROCHROA, DENDROIDES. 



Gen. PYROCHROA, Fab. Cantharis, Lin. 

 Four posterior feet with four tarsi, the two anterior with five ; 

 thorax orbicular ; antennae pectinated ; maxillary palpi longer 

 than the labial, and terminated by a joint in form of a re- 

 versed triangle. 



The larva of this genus has an elongated, depressed body, terminated by two points, 

 with the head strong and analogous to that of the perfect insects. The perfect in- 

 sect is found on roads, footpaths, and at the foot of hedges. 



P. rubens, Fab. Black, with the head, thorax, and elytra, of a 

 scarlet red colour, without spots. 5 lines long. Inhabits Europe.

TRIBE III. MORDELLON^E. 



Body elevated, arched, with the head low ; thorax semicircular; 

 elytra very short or of ordinary length, and ending in a point, 

 like the abdomen ; antennae often serrated, those of many 

 males tufted or pectinated ; palpi of various forms. 



This tribe is thus divided by M. Latreille : 



A. Antennae of the males flabelliform or pectinated ; palpi almost filiform. 



Gen. RIPIPHORUS, (hooks of the tarsi bifid) ; ^ELECOTOMA, MYODITES. 



B, Antenna? of the males serrated ; maxillary palpi terminated by a larger triangu- 

 lar or securiform joint. 



Gen. MORDELLA, ANASPIS, SCRAPTIA. 



Gen. MORDELLA, Lin. Lat. 



All the joints of the tarsi entire ; maxillary palpi terminated 

 by a larger joint than the preceding, and dolabriform ; an- 

 tennae simple or serrated ; last segment of the abdomen pro- 

 longed into a point in tbe females. 



M. aculeata, Lin. Shining black, without spots, and covered with 

 a silky down j antennae serrated ; ovipositor the length of the tho- 

 rax. Shaw, vi. pi. 38. 



TRIBE IV. ANTHICIDES. 



Penult joint of the tarsi bilobed ; body oblong, with the thorax 

 cordiform or divided into two knots ; last joint of the maxil-
