96 NORTHERN ZOOLOGY. 



larly Creophilus, the upper-lobe in both being obliquely divided into two articula- 

 tions, and the lower being large, short, and very hirsute ; whereas in Necrodes and 

 the other Silphidce, though the upper-lobe is the same, the lower terminates in a 

 sharp incurved spine — the mandibles of Creophilus and Necrophorus differ a little, 

 the latter not terminating in a long laniary acumen, and its teeth being less pro- 

 nounced. As to external form Necrophorus is evidently intermediate between 

 Creophilus and Necrodes. It has the disengaged head and neck, and truncated 

 elytra and wings of the former, and the thorax and general aspect of the latter 

 tribe. When we add to this that both live upon dead flesh — no doubt can remain 

 of their affinity- Indeed a general agreement in their trophi, especially the max- 

 illce, is as strong a proof of affinity as can well be furnished.
