Buckton’s description from English specimens found on the red 
currant (Ribes rubrum ) and gooseberry ( Ribes grossularia ) is as 
follows: 
Apterous viviparous female. —Length of body .085 inch; of antennae 
.09 inch; of honey-tubes .015 inch. Long oval. Shining yellow or 
green, with darker green mottlings. Front flat, garnished with short 
bristles, as also are the sides. Antennae long and very fine. Lloney- 
tubes, pale green. Eyes bright red. Tail obtuse. Legs yellow or 
greenish. 
Under a high magnifying power these bristles are capitate, a fact 
not in accordance with the experience of Passerini, as regards the 
Italian species. 
Pupa. —Large, shining yellow or green. Two brown spots on the 
occiput. Abdomen convex and glistering. 
Winged viviparous female .-—Length of body .10 inch; antennae .09 
inch; honey-tubes .02 inch. Bright greenish-yellow. Head pale olive. 
Eyes red. The three ocelli obvious. Antennae fixed on small tubercles. 
Prothorax with an indented olive band. Thoracic lobes brown. A 
stellate spot is seen on the post thorax, succeeded by six or seven 
irregular transverse bands on the abdomen of varying thickness (width); 
four or five spots on each lateral edge. Honey-tubes green or olive, 
cylindrical, or at least very slightly clavate. Legs green, with olive 
femoral points and tarsi. Wings broad, with yellow insertions, green¬ 
ish sub-costa and veins. Stigma grey. This he says is found plen¬ 
tiful on the plants mentioned, from May to July. 
The species which Koch describes as Rhopalosiphum ribis is found 
on the currant in May, congregated on the. underside of the leaves 
and causing them to cup and blister as is the case in this country. 
The winged specimen is bright yellow; the head brown; eyes black 
or dark brown; prothorax yellow; the disk of the thorax or thoracic 
lobes, black; abdomen bright yellow, with black points along each 
lateral margin, and three transverse black bands on the posterior por¬ 
tion. Honey-tubes slightly enlarged towards the tip; extending rather 
beyond the tip of the abdomen, yellow. Tail rather short, yellow. 
Body elongate oval. Antennae dusky, rather longer than the body; 
third-joint pustulate on the sides, longer than the fourth, but not 
quite as long as the seventh; the basal joints scarcely presenting any 
enlargement on the inner margin. Legs pale, dusky at the joints and 
tarsi. 
The wingless specimen , as figured, is pale yellow; eyes small and 
dark; some ochreous points along the lateral margins of the abdomen; 
legs and antennae pale; honey-tubes cylindrical, reaching tip of the 
abdomen. 
The Aphis ribicola of Katlenbach or Siphonopliora ribicola of Koch, 
as figured and described by the latter, is as follows: 
Winged specimen. —Body grass-green; antennae, head, eyes, thoracic 
lobes, spots on the abdomen, and the tail, black. The abdomen has 
a row of black dots along each lateral margin, and some partial bands 
of the same color. The honey-tubes, extend rather beyond the tip of 
the abdomen, are cylindrical, black at base and pale or yellowish to¬ 
ward the tips. Tail rather short, scarcely half as long as the honey- 
tubes, black. Discoidal veins of the fore wings nearly straight; stigma 
long, narrow, with scarcely any inner angle at the point where the 
fourth vein arises. Fourth or stigmatic vein, curving regularly in the
