British Homoptera-Cicadina. 41 
Very abundant in damp grassy places. Of the same 
robust build as A. grisescens, but easily distinguished by 
the markings on the crown. The dark form (A. piceus, 
Scott) has the frons black, with yellow transverse lines ; 
the crown (by reason of the exaggeration and confluence 
of the normal markings) black, with a few yellow spots, 
or entirely black; and the pronotum, scutellum, and 
elytra lighter or darker pitch-brown, in the latter owing 
to the close black speckling, after the manner of 
A. obscurellus, male.

Brownish yellow; areas of the elytra often narrowly margined 
with fuscous or black. Crown one-half longer than half its basal 
width, one-half longer in the middle than at the sides, its free 
sides nearly straight, angle distinct but obtuse; basal markings 
large, horseshoe-shaped ; interocular line interrupted, but scarcely 
thickened in the middle, often broken up into four spots, on the 
hinder half of the disk a pair of whitish stripes narrowly margined 
with fuscous reaching as far as the interocular line; interocellar 
line broken up into four spots; infraocellar line biarcuate, very 
distinct. Frons black, with a middle stripe and the transverse 
lines yellow. Pronotum a little longer than the crown, sometimes 
with four wide dark stripes. Scutellum yellow, generally without 
markings. Elytra in the male a little longer, in the female a little 
shorter, than the abdomen, narrowly rounded at the apex, the 
areas frequently more or less distinctly ocellate, but very often 
without markings ; nerves pale. Abdomen black; hind margins 
of the dorsal segments narrowly whitish behind. Last ventral 
segment (2) a little longer than the preceding, its hind margin 
simple, very feebly concave. Legs black, the knees and the outer 
side of the tibiz for some distance from the base brownish yellow. 
Length, 3 mm. 
Widely distributed, but not very common. Easily 
distinguished by its small size and Deltocephaloid facies ; 
it forms, in fact, a connecting link between the genera 
Athysanus and Deltocephaius, if we pass to the latter by 
way of D. pulicaris.
