British Homoptera-Cicadina. 95 
of this insect are not uncommon, but they may always 
be distinguished from the next species by the minute but 
constant differences in the pattern on the elytra.

Tettigonia concinna, Germ., Faun. Ins. Eur., 14, 22.

Eupteryx concinna, Ferrari, Cicad. agri Ligust., 78 
and 79. 
Exceedingly like a pale whitish example of the last species, but 
although there is sometimes the faintest possible indication of the 
black spot on the nerve which divides the first from the seecnd 
apical area, it is never developed, and in place of the ill-defined 
brown line which bounds the apex of the brachial area in E. 
pulchellus the apices of both the brachial and suprabrachial areas 
in the present species are bounded by a sharply-defined black line. 
Length, 4—4} mm. 
Not uncommon on oaks; occurring with the last 
species. The distinctive characters given above are 
supplemented by great structural differences between the 
male genitalia of this species and EH. pulehellus. 
vi. TypHtocysa, Germ. (PI. ILI., fig. 23). 
Germar, Silb. Rev. Ent., i. (1833). 
Body small, cylindrical. Crown crescent-shaped, more or less 
pointed. Elytra much longer than the abdomen, the four apical 
areas well-defined, the second triangular; membrane wanting. 
Submarginal wing-nerve incomplete ; first and second wing-nerves 
confluent before the apex and running to the margin as one nerve ; 
third wing-nerve simple, the straight transverse nerve connecting 
it with the second wing-nerve, prolonged in a suboblique direction 
as far as the submarginal nerve. 
This genus, as here limited, is equivalent to Anomia, 
Fieb. (Cicad. d’Eur., pt. 1., 128). The species are 
mostly arboreal in their habits.
