size. Denny notes especially that hulhifer varies exceedingly 

 in that respect, some being nearly twice the size of others. 



As regards the sexes of Bythinus bulbifer, I may observe 

 that the statement of Erichson (Col. March.) and Thomson 

 that the anterior tibiae of the male are armed with a little 

 tooth internally before the apex is scarcely accurate; in 

 reality, the tibia is notched on the inner side, as in some 

 Geodephaga. This notch is noticed by Denny in P.^elaphus 

 lonf)icornis (the male of P. mnguineus). 



I may here refer to the other species above mentioned, 

 Bythinus clavicornis, of which Denny quotes only a pair, 

 in the British Museum, one taken at Swansea and the other 

 at Falmouth, These two specimens are still extant in the 

 national collection, and it is, I presume, to one of them that 

 the Leachian male quoted in Wat. Cat. is to be referred. 

 The insect appears very rare everywhere; being recorded 

 from Mannheim, Berlin and Leipsic in Germany, by 

 Reichenbach ; from England only (very rarely\ by Aube; 

 and from Britain, Sweden, France, Germany and Russia, by 

 De Marseul. It is also included in Grenier's Catalogue of 

 French Coleopteraj having apparently been taken in France 

 since the publication of Fairmaire's " Faune Francaise," 

 wherein it is stated that M. Reiche possesses an English 

 specimen. 



The insect is larger than any others of the genus, brilliant 

 dark brown in colour, with the elytra and abdomen darker 

 still. The antennae are alike in both sexes.
