The head is not quite as long as the protliorax, 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 j 
partially to cover the anterior coxae; 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 m front. The fiont is 
irregularly and variably specked and blotched with white, and the - 
iu"® are also slightly marked, especially immediately beneath the I, 
eye. The basal joint of the antennas 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 ft 
entire antenna with its bristle being considerably longer than both | 
head and prothorax. , I I 
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 i 
being usually quadrate. This row is continued backwards, along i 
the "sides of the thorax to the abdomen, beneath the wings, as a I 
broken, irregular band. The scutellum is large, triangular, longi* 
tudinally depressed m the middle, with a lineai transverse mipres- § 
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- l 
nected in the middle by a short, transverse line. These stripes t 
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 j|! 
transverse bands, widest on the sides, where they form a nearly i 
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 marginal i 
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. • I 
Three other species of this family have been reported as injurious 
to the apple: two by Walsh* (Erythroneura malefica, Walsh, and ii- 
maligna, Walsh), and one by Lintneri ( Jassus irroratus, bay).
