rior coxae, which are furnished with a distinct tro- 
chantin, and are elongate, subcylindrical, and very 
projecting. 
The species of Pyrochroa, commonly known as 
“ Cardinal beetles/’ are bright scarlet or brickdust- 
red in colour, moderately large, with serrate or pecti- 
nate antennae, pedunculate mentum, acutely bifid man- 
dibles, elytra not covering the sides of the abdomen, 
and loug legs. They are very active and rapacious ; 
flying readily and strongly in the hot sunshine, and 
often simulating death when captured. The largest, 
P. coccinea, is distinguished by its black head ; it is 
not uncommon in woods in the south. I have found 
it, in all its stages, in great numbers under the bark 
of a felled tree at Dareuth, in Kent. 
The CEdemerid.® are elongate, slender, with thin legs 
and antennae, no abrupt neck to the head, simple 
hooks to the tarsi, the mandibles flattened and bifid 
at the apex, and the penultimate joint of the tarsi 
bilobed. Their larvae live in rotten wood, and resem- 
ble those of the Longicorns, to members of which 
section the perfect insects also present a certain like- 
ness. 
Nacerdes melanura, not unlike a large Telephones, is 
found at the seaside ; it is testaceous with the apex of 
the elytra black, and is especially noteworthy from the 
fact of its male possessing twelve joints to the antennae, 
though the female has the normal number. It flies 
strongly in the hot sunshine, and is often taken on old 
posts on the shore ; the larvae even living in timber 
that is periodically covered by the tide. 
Oncomera ( Dryops ) femorata, the largest of the 
family, is a very graceful, slender insect, with very long
