This is, perhaps, a variety of Flata serratula, of Fab., which 
he says, occurs in England, upon Thistles. 
I have not met with any statements relative to the early stages 
of the insects of this genus. In woods, I often fall in with the 
larva of one species, which I take for C. nervosus, in cavities 
in the ground beneath large stones, or in the runs of moles or 
mice, where it may feed on roots or underground stems.
