CURRANT. LEAVES. 
leaf leaving the skin entire, producing a beetle which occurs 
upon the bushes in May and June, its wing covers of an oblong 
square form with elevated lines and intervening rough grooves, 
its color light yellow, black beneath and with the antennge, the 
sides and two stripes on the thorax and variable lines on the wing 
covers also black. Length 0.15. As I have commonly met with 
this beetle upon the wild black currant, I infer with considerable 
confidence that its larvae subsist upon the leaves, mining them as 
the Rosy Hispa No. 37 does those of the apple. 
145 . Currant Aphis, //phis Jiibis, Linn. (Homoptera. Aphids.) 
Irregular bulges or blister-like elevations of a brownish red 
color upon the leaves, opposite which on their under sides are 
corresponding hollows occupied by multitudes of plant lice suck¬ 
ing the juices of the leaf and sometimes covering the green suc¬ 
culent young shoots also; many of them without wings and of a 
pale yellowish color; others with clear glassy wings, and these 
mostly black with the abdomen light green and having a slightly 
protruded tail and black horns or honey tubes reaching about hall 
way to the tip, with a row of deep green or black dots along each 
side forward of the horns, the antennae and legs also black with 
the shanks and bases of the thighs pale, and with the third 
oblique vein of the wings obliterated at its commencement. 
Length 0.13 to the tips of the wings. More or less common in 
every garden, attended by ants and devoured by lady-birds 
( Coccinellce ) which are always seen on the same bushes, and which 
with other destroyers often wholly exterminate these lice so that 
only the bulged spots on the leaves remain to indicate their 
having been there. 
146 . Oblique-striped leaf-hopper, Erythroneura olliqua, Say. (Homop- 
tera. Tcttigoniidee.) 
Puncturing the leaves and sucking their juices, a very small 
white leaf-hopper 0.12 long, its head and thorax with two bright 
blood-red or orange stripes and three short oblique ones on the 
wing covers, the outer one placed on the shoulder, the middle one 
on the disk and the inner one ending on the middle of the inner 
margin. This is common, particularly upon the bushes of the 
wild currant, but occurs on various other shrubs and trees
