metamorphosis there, and greatly astonished the inhabitants of 

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

 E. seneus^L..; 01iv.,Col., lb., viii, 83. Six lines long, bronze 

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

 North of Europe. 



E. germaniis, 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. cruciatus, Oliv., lb. IV, 40. A pretty European species, 

 with the appearance of the ?eneus, 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. III, 25; v, 51. Black; thorax 

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

 tremity; antennae of the male pectiniform. Europe. 



E. ruficolUs, 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. ferrugineus, 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 



Campylus, Fisch. — Exophthalmus, Lat. — Hammionus, Muhfeld(2). 



Elaterides with filiform palpi and antennae, pectinated from the 

 fourth joint, will compose a last subgenus, that of 



Phyllocerus(3)-

 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 Horse 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. cindus.
