A. tinctus, Reut., l. c., 212, 215 and 227, 43. 
Upper side greenish yellow or greyish green. Crown in the 
male as long as half its basal width, about one-half longer in the 
middle than at the sides, free sides feebly arcuate, angle widely 
rounded ; in the female distinctly longer than half its basal width, 
nearly twice as long in the middle as at the sides, free sides 
straight, angle blunt ; the dark markings are of the same type as 
in Athysanus Sahibergi, &c., but are rarely developed, although 
their position is generally indicated by sundry pale brown spots or 
lines. Frons pale brown, with the apex, a linear middle stripe, 
and the side-lines yellow. Pronotum about one-third longer than 
the crown. Elytra more or less strongly tinged with fuscous at 
the apex; nerves yellow. Abdomen black, connexivum and the 
apex beneath yellow. Legs yellow, with black points; under side 
of thighs sometimes with a black line indicating the commence- 
ment of a band on the apical third. Length, 6}—7 mm. 
On various trees in woods; common. A variety of 
this species, which has the inner areas of the elytra 
more or less filled up with dark fuscous, is the T’hamno- 
tettix stupidula, Zett., and another, in which the head, 
pronotum, and scutellum are tinged with red, is the 
T. tincta of the same author. Judging from Kirsch- 
baum’s description (Cicad., 94, 23) his 7. Zelleri is 
quite distinct from this species.
