224 Hlemiptera- Heteroptera. 
Mickleham, Butler ; Pitlochry, Norman; Forres and 
Orkneys, Reuter; Rannoch, Marshall; St. Ives, J. H. 
Mason. ; 
M. ruficornis, Fall.—Dark or pale green, antenne 
and tarsi generally more or less red, basal joint of the 
antennz about as long as the head, third joint shorter 
than the second; pronotum with the sides sinuate, feebly 
punctured ; scutellum with a slightly raised pale central 
line ; elytra longer than the abdomen in the ¢, shorter in 
the ?; legs slender, posterior tibi straight, with fine 
short spine-like hairs. 
A form occurs on sandhills near the coast, which is 
larger and paler, with pale antenne, but it is not con- 
sidered by Dr. Reuter as more than a variety of this 
species; the third joint of the antennz is shorter than 
in the typical form. 
L. 6-8 mm. 
Common and generally distributed in similar situations 
to the other species of the genus. 
TERATOCORIS, Fie. 
Rather similar to the two preceding genera in shape, but 
at once distinguishable by its transverse head, prominent 
rounder eyes, projecting considerably beyond the margins 
of the pronotum, and its transversely impressed vertex, and 
also by its dimorphic nature, both sexes occurring in the 
macropterous and brachypterous forms. We have three 
species in this country of the four recorded from Europe, 
all of which are more or less rare, and occur in marshy 
places by sweeping, especially near the sea,

nearly glabrous, its pubescence very fine and 
scarcely observable F - ANTENNATUS. 
(1) 2. Basal joint of the antenne not red, with 
distinct projecting hairs. 
(4) 3. Basal joint of the antenne in the male shorter 
than the fourth, pronotum and scutellum in that
