genus, the antenna 1 are usually quite short extending but little be¬ 
yond the end of the thorax; they are but six jointed, and in our 
species are similar in form to those of Aphis. 
SlPHA RUBIFOL1I. New sp. 
This species found on the leaves of the blackberry, bears a close 
resemblance to the Aphis mail in color, size and habits, but there is 
one marked difference which would seem even to forbid its generic 
association with that species. 
Winged female .—Head and thorax black; abdomen green; wings 
with dark veins, and when seen together above the back, in the living 
insect* presenting a slightly smoky appearance. The fourth or stigmatic 
vein regularly curved; stigma elongate, pointed, usually slightly dusky; 
the second fork of the third vein about equally distant from apex and 
third vein, in the wing on the one side, while it is much nearer the 
apex in the wing on the other side, of the only specimen where this 
character is observed. (Other winged specimens were examined, but 
no attention was paid to this character until after they were mounted, 
when it was found only one winged specimen had been preserved. 
Particular care was not taken of them, as I felt confident from my 
examination at the time, which was somewhat hasty, that they were 
identical with A. mali). Costal and sub-costal veins pale on their 
basal half. Abdomen pale green, with the margin and a line, darker 
green. Honey-tubes short, cylindrical, not reaching to the tip of the 
abdomen (base of the tail), pale, transparent green. Tail short, conical, 
rather obtuse. 
Antenme of all examined, winged and wingless, at the time they 
were found and those preserved, are but six jointed under the strongest 
magnifying power I have at hand; not quite as long as the body; 
first and second joints short and thick as usual in Aphis; third joint 
longest, exceeding in length fourth and fifth joints combined; fourth 
about half the length of the third, and a little longer than the fifth; 
sixth or apical joint setaceous and of the same form as in those with 
seven joints, shorter than the third, but longer than the fourth. The 
fifth is the usual form of the sixth, but rather longer in proportion; 
the third is longer than usual but no constriction, or amalgamation of, 
two joints, can be seen in any specimen examined; usually fuscous but 
not black, pale at base. Legs pale, tarsi fuscous. 
Wingless .—Body oval shaped; abdomen pale green, a darker green 
transverse stripe at the base, with usually five wavy lines of the same 
color, running from it toward the tip, occasionally there are dark green 
spots; head, legs and antennae pale, with a yellowish tinge; tarsi and 
knees dusky. Antennae short, not reaching to or beyond the honey- 
tubes; honey-tubes short, as in the winged. 
Found on the underside of the leaves of the common blackberry, 
usually along the mid rib or one of the larger lateral veins, causing 
the leaf to curl downwards. When near or along a branch vein, the 
curling is very irregular, contorting the leaf. 
To all appearance, save the antennal character, this seems to be a 
true Aphis, but this, according to present classification, would exclude
