British Homoptera-Cicadina. 29 
points on the outer side. Pygofer with three black spots above ; 
genital valve extremely short; plates about as long as the last 
ventral segment, obtusely rounded at the apex. 
g. A small suboval spot in the middle of the last dorsal 
segment, the hind margin of the latter and a fine line down the 
middle of the pygofer above black; otherwise coloured like the 
male. Last ventral segment one-half longer than the preceding, 
subtruncate behind ; saw-case about three times as long, its apical 
third free. 
Macropterous form.—HElytra dirty whitish, subopaque, scarcely 
reaching to the apex of the last dorsal segment; appendix of 
nearly equal width throughout, reaching as far as the first apical 
area. Length, 23—4 mm. 
Common on the ground on heaths, coast-sands, &c. ; 
the macropterous form very rare. On the sand-hills at 
Hunstanton, in July, 1885, I took several examples of a 
large pale race of this species. In actual measurement 
these are about one-half larger than the ordinary form 
(f 4 mm., 2 54 mm.), but the difference in size is 
apparently much greater ; the ordinary form occurred in 
a salt-marsh just behind the sand-hills, but the two 
races were not intermingled. I have not detected any 
structural differences between the two. Doratura homo- 
phylla, Flor, a species not unlikely to occur here, is 
distinguished by the genital valve in the male, which is 
nearly as long as the last ventral segment, and the last 
ventral segment in the female, which is twice as long as 
the preceding segment, and roundly produced behind. 
vii. Paramesus, Fieb. (Pl. IIL, fig. 9). 
Fieber, Neue Gatt. und Art. Homop., 10, 27 (1866). 
Crown sublunate or slightly produced, with a wide transverse 
impression on the disc. Forehead and front of the crown trans- 
versely striate. Frons flattish, dull, exceedingly finely and closely 
punctured. Sides of pronotum very short, not margined. LElytra 
about as long or a little longer than the abdomen, normally with 
two transverse nerves; appendix very narrow or entirely wanting. 
Wings of the Jassid type. 
Our two species may be distinguished as follows :— 
Frons between the antenne nearly three times as wide 
as the base of the clypeus. Insect broad .. .. L. nervosus. 
Frons between the antenne not more than twice as 
wide as the base of the clypeus. Insect narrow .. 2. phragmitis.
