 palpi with the last joint subulate, conic. Labial palpi 

 with last joint obtuse. 



Obs. This genus has afforded the subject of a learned 

 and interesting monograph, by W. Spence, Esq. pub- 

 lished by the Linnaean Society in the eleventh volume of 

 their Transactions, to which we refer the reader for de- 

 scriptions of the species.

 behind, the hinder angles obtuse, the middle slightly fo- 

 veolated. Antennae somewhat filiform.

 club. 



Sfi 1. Cellaris. Testaceous ferrugineous, widely punc- 

 tate, pubescent. Thorax finely denticulated, on each

• The genus Thanatophilus of Leach, which contains Silpha tinuata of Fabricius, differs from this division merely in having the 

 ape* of the elytra of the female deeply notched j we have therefore not adopted it.
