Fabricius mentions a variety of Elater cupreus with 
simple antennae, and an aeneous body, which maybe the fe* 
male sex of our insect. It is, however, not only distinguish- 
able from that species by the colour of the elytra, but like- 
wise by being broader in proportion to its length. Panzer 
has figured it tolerably well, and appears to have been ac- 
quainted with the other sex, the antennae of which he also 
figures. Paykull says that he has seen a variety of the male 
of Elater pectinicornis with cupreo-purpurascent elytra, 
which is probably our insect ; but it is certainly distinct 
from Elater pectinicornis , being much shorter in proportion 
to its size.
