38 Mr. James Edwards’ Synopsis of 
in the middle than at the sides, in the female as long, in the male 
a little longer than half its basal width, its free sides curved, and 
the angle rounded off. All the markings on the head, except the 
infraocellar line, more or less distinct. A few black or fuscous 
points on the front half of the pronotum, a double fuscous stripe 
on the scutellum, sometimes continued on the hinder half of the 
pronotum, and the areas of the elytra, more or less filled up with 
fuscous. Length, 443—5} mm. 
Pitlochry (Norman); Norfolk. Not common; some- 
times it occurs in company with A. sordidus, but it 
appears to be restricted to very marshy places; in the 
field it might be easily passed over as A. obsoletus, 
although I have seldom met with it in company with 
that species.

Greyish yellow; nerves of the elytra whitish. Crown two- 
thirds longer in the middle than at the sides, subequal in length to 
the pronotum, its free sides straight, and the angle pointed; inter- 
ocular line not interrupted in the middle, forked at each end, the 
lower branch joining the basal spot; interocellar line entire; infra- 
ocellar line obsolete or wanting. Pronotum and scutellum some- 
times with a few fuscous markings. Elytra a little shorter than 
the abdomen, narrowly rounded at the apex, in the macropterous 
form as long as or a little longer than the abdomen, with the 
suture and some of the areas narrowly margined with blackish, 
and the apical areas more or less filled up with the same colour. 
Hind margin of the last ventral segment in the female sub- 
angularly concave, with a bifid process in the middle. Length, 
5—54 mm. 
Moderately common amongst grasses, May to July. 
An entirely pale form is not unfrequent.
