two first-named species is uncertain. FE. cardinalis was first discovered by 
Prof. Schiddte in Italy, but occurs also in Denmark. . dibaphus 3 has 
the third jomt of the antennz triangular. The four red species are dis- 
tinguished principally by the proportions of length between pronotum, 
elytra, and antennz. The elytra are in £. sanguineus twice and a half 
as long as the pronotum, in J. cardinalis rather less; in E. dibaphus 
the proportion is twice and three quarters, and in E. coccineus about three 
times. The antenne are always about one-sixth shorter in the 2? than in 
the ¢; in LE. sanguineus 8 they equal the pronotum to the point of the 
hind corners; in EH. dibaphus 3 and FE. coccineus g they exceed this mea- 
sure not alittle; but in HL. cardinalis $ they are not longer than the pro- 
notum measured along the middle line; in E. cardinalis the pronotum 
equals in length its own width measured over the hind corners, whilst it is 
shorter inthe three other species, from which. cardinalisis also distinguished 
by the punctures being much coarser on the head and pronotum, which are 
quite dull, and by the sides of the body being parallel in the middle. The 
transversal dip at the base of the pronotum is very marked in all these species 
except E. coccineus, where it is strikingly flat and shiny; but the extent 
and depth of the middle groove varies im all four species. Nor is the co-= 
lour of the hairs of any value for the distinction of these difficult species. 
The antennze are black in FE. sanguineus and FE. dibaphus, brown in E. 
cardinalis, and light brown in FE. coccineus.
