Species of Elateridcp. in the Siephensian Cabinet. 89 



these so-called species plentifully, inform us that they have 

 found the extreme varieties (i. e. brunneus and fugax of 

 the older authors) in copula. They have long been sus- 

 pected to be one species ; and, in the most recent work 

 upon the German Elater'idce (that of Kiesenwetter) they are 

 put together. The Sericosomus hrunnipennis of Stephens, 

 moreover, forms an intermediate variety between S. fugax 

 and S. brunneus.

Stephens' description appears to belong to the true L. serra- 

 ticornis, but of that insect I have never seen a British 

 example.

Brucleri, Steph., Man. | 



Not in Stephens' collection ; I have seen no British specimen 

 of the Elater Bructeri, Fab., which now forms the type of 

 Kiesenwetter's genus Pheleles. 



nigrinus, Payk. | 



Not in Stephens' collection ; the Elater nigrinus of Paykul 

 {Elater nigrinus, Kiesenvv. — Ampedus nigrinus, Germ.), 

 however, is known to be a British insect.

* In Leach's collection there are two specimens of an allied species of Limo- 

 nius, of a shorter form than the L. minutus, and with the thorax more finely and 

 thickly punctured. I believe it to be the S. lythrodes of Gerraar.
