*54. NECROBIA RUFIPES, Fab. 
A blue variety of this species was common at Gorrite; indeed it seems to 
be found all over the world. 
I may here observe that I have seen only one species of Corynetes*, which is 
the violaceus of Fabricius ; it is the type of his genus, and is distinguished by 
5-jointed tarsi and a linear club of 3 nearly equal joints, whereas * Necrobia 
rufipes 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.

external one, both ciliated. Palpi rather long and 4-jointed, clothed 
with long hairs, basal joint short and slender, 2nd and 3rd of equal
