COLEOPTERA SILPHIDTE.

doubt its existence (see fol. 566.), although he admits it in his fol. 379. 

 Mr. Spence has shown the relations of Choleva both with Dermestes 

 and Silpha, and noticed the analogy between it and Mordella, which 

 is much more decided than that existing between Scaphidium and 

 Ripiphorus, noticed by MacLeay ; which latter, indeed, is very 

 remote. 



The British genera Scaphidium and Scaphisoma are found in agarics, 

 fungi, and under the bark of rotten trees, whilst the other species of 

 tlie family are more frequent amongst bones, and in the neighbour- 

 hood of dunghills. In some species of Catops, the anterior and 

 intermediate tarsi of the males are more or less dilated. 



The second family Silphid/f. Leach (Silphales La(r.), is distin- 

 guished by the depressed form of the body (Jtf/- 10. i. Silpha 



4-punctata) ; the more or less depressed head often posteriorly 

 narrowed into a neck (Jiff. 10. 7. head of Necrophorus beneath) ;
