14 Lh. miplera-Fleteroptera. 
posterior or lateral angles into spines or lobate processes ; 
scutellum very large, reaching to the base of the membrane, 
or in the Scutellerina almost or completely covering it. 
Elytra composed of clavus, corium, and membrane. Con- 
nexivum usually more or less reflexed. Legs simple in 
most of the genera, but spinose in the Cydnina. Tarsi 
2 to 3-jointed. 
Of this showy family we have only a few genera in Great 
Britain, they all occur on various trees and plants, and 
most of the species may be said to be more or less rare, 
only a few really occurring in abundance.

Of this well marked genus there are only three European 
species, of which we have only one in this country ; they all 
occur in sandy localities, fuliginosus being found on our 
coasts under Hrodium, etc. O. dorsalis occurs in France on 
the sandhills of the north coast, and may yet be added to our 
list; it may be known from fuliginosus by the silvery 
pubescence of its under side.
