The head is not quite as long as the prothorax, is regularly and 
broadly rounded in front, the vertex slightly convex, with a slender 
longitudinal raised line, vanishing forwards. The ocelli are on the 
anterior margin of the vertex, where it bends downwards _ to 
join the front, and are more than twice as far from each other 
as from the eyes. The cheeks are expanded laterally so as 
-partially to cover the anterior cox; and the vertex is marked by a 
median white line with a white blotch on either side of its base. 
Each ocellus is situated in a circular white spot, and a series of 
irregular dashes of white borders the eye in front. The front is 
irregularly and variably specked and blotched with white, and the 
juge are also slightly marked, especially immediately beneath the 
eye. The basal joint of the antenne is no longer than broad, the 
second joint is nearly twice as long as the preceding, the third 
slender fusiform, longer than the first and second together, the 
entire antenna with its bristle being considerably longer than both 
head and prothorax. 
The pronotum is about as long as the scutellum. Its posterior 
border is straight, and its anterior regularly arcuate, giving the 
whole a semi-lunar form. Along its anterior margin is an are of 
six or eight irregular or variable spots or blotches; the middle pair 
being usually quadrate. This row is continued backwards, along 
the sides of the thorax to the abdomen, beneath the wings. as a 
broken, irregular band. The scutellum is large, triangular, longi- 
tudinally depressed in the middle, with a linear transverse 1mpres- 
sion marking off the posterior third. It has a white lateral border, 
interrupted at the transverse impression; and on either side of the 
middle is a longitudinal white stripe, the pair being usually con- 
nected in the middle by a short, transverse line. ‘These stripes 
extend from the transverse impression to the base of the scutellum, 
reaching forward beneath the pronotum. Beyond the impression is 
a triangular white patch connecting the ends of the longitudinal 
stripes above mentioned. 
The abdominal segments are irregularly washed with whitish in 
transverse bands, widest on the sides, where they form a nearly 
continuous stripe, and interrupted on the middle of the back except 
on the last segments, where they are unbroken. The genital valves: 
are lightly washed with white beneath. 
The elytra are yellowish, and the wings hyaline. In the former 
(Plate XIV, Fig. 4) the terminal vein coincides with the margin of 
the elytra, while in the latter it is sub-marginal, leaving a narrow 
border of membrane beyond it. The legs are green, the tarsi paler, 
the tarsal claws or spurs pale brown. 
Three other species of this family have been reported as injurious 
to the apple: two by Walsh* (Erythroneura malefica, Walsh, and EH. 
maligna, Walsh), and one by Lintnert (Jassus irroratus, Say).
