Cicad. agri Ligust., 61, 6 and 65, 148, fig, p. 66. 
Jassus atomarius, Marsh., Ent. Mo. Mag., 84, 22. 
Crown with the basal markings punctiform, the interocular line 
is represented by a fine straight line running obliquely inwards 
from the front angle of each eye half-way to the base, and the 
interocellar line by a punctiform spot adjoining each ocellus. 
3; genital plates triangular, about three times as long as the 
triangular genital valve, completely covering the styles. 9; last 
ventral segment much longer than the preceding, its hind margin 
with a very feeble angular notch in the middle; lateral angles 
much produced. Length, 7 mm. 
Widely distributed, but much less common than the 
next species.

Thamnotettix mixta, J. Sahl., Not. Fenn., xi., 209, 1. 
Allygus miztus, Scott, Ent. Mo. Mag., xil., 170, 1. 
Crown with the basal markings obsolete, the interocular line 
represented by a punctiform spot on each side of the disc, and the 
interocellar line by four punctiform spots. g; genital plates 
triangular, more than twice as long as the triangular genital valve, 
completely covering the styles. 9; last ventral segment more 
than twice as long as the preceding, its hind margin nearly 
straight; the lateral angles not produced. Length, 6;—7 mm. 
Common on oaks. This is a very variable species in 
the matter of the black speckling of the elytra; some- 
times this is very scanty, and at others is so much 
exaggerated and confluent that the elytra appear deep 
black with white transverse nerves; immature examples 
have the upper fore parts tinged with green.
