346 INSECTA. 



metamorphosis there, and greatly astonished the inhabitants of 

 the faubourg Saint-Antoine by its, to them, extraordinary light. 

 E. aeneus,L.; Oliv., Col., lb., viii, 83. Six lines long, bronze 

 green; glossy; elytra striated; legs fulvous. Germany and the 

 North of Europe. 



E. germanus, L.; Oliv., lb., 11, 12. Very common in the 

 vicinity of Paris, and only differing from the aeneus in the colour 

 of its feet, which are black. 



E. cruciatas, Oliv., lb. IV, 40. A pretty European species, 

 with the appearance of the aeneus, but smaller; black; two lon- 

 gitudinal red bands on the thorax, near the lateral margin; 

 elytra yellowish-red, with a black line near the anterior angles 

 of their base and two bands of the same colour forming a cross 

 on the suture. Rare near Paris. 



E. castaneus, L. ; Oliv., lb. Ill, 25; v, 51. Black; thorax 

 covered with a reddish down; elytra yellowish with a black ex- 

 tremity; antennas of the male pectiniform. Europe. 



E. rujicollis, L. ; Oliv., lb., VI, 61, a, b. Three lines in 

 length, and of a shining black; posterior half of the thorax red. 

 North of Europe. 



E. ferruginous, L.; Oliv., lb., Ill, 35. Ten lines in length; 

 black; the thorax, its posterior margin excepted, and the elytra 

 deep blood-red. On the Willow. The largest species in Eu- 

 rope(l). 

 Sometimes the head is free posteriorly, or is not sunk to the eyes, 

 which are protuberant and globular. The antennae are inserted 

 under the edge of a frontal projection, depressed and arcuated ante- 

 riorly. The body is long and narrow, or nearly linear. Such are 

 those which form the subgenus 



Campylvs, Fisch. Exophthalmus, Lat. Hammionus, Miihfeld(2). 



Elaterides with filiform palpi and antennas, pectinated from the 

 fourth joint, will compose a last subgenus, that of 



Phyllocerus(S).

 his Ind. Entom.; Herbst., Col., andPalisot de Beauvois, Insect. d'Afr. et d'Amer. 

 The genus of Dima of M. Ziegler, a species of which, called elateroides, has been 

 figured by M. Charpentier in his Horx Entomol., VI, 8, presents no character by 

 which I can clearly distinguish it from the preceding one. 



(2) See Fischer, Entom. Russ., II, p. 153. This subgenus comprises the Elater 

 linearis, L-, of which his mesomelas is a mere variety; the E. borealis, Gyll,, and 

 his E. cinctus.
