Family. CLERIDiî:. 



*54. Necrobia rufipes. Fah. 



A blue variety of this species was counnon at Gorrite ; indeed it seems to 

 be found all over the world. 



I may here observe that I have seen only one species of Cbr;/«f to*, which is 

 the violaceus of Fabricius ; it is the type of his genus, and is distinguished by 

 6-jointed tarsi and a linear club of 3 nearly equal joints, whereas * Necrobia 

 rujipes and its congeners have 4-jointed tarsi and an obovate club of 3 joints, 

 the terminal one being very large, and the palpi are different ; notwithstanding 

 which the Baron Dejean includes them all in one genus under the name of 

 Corynetes.
