Dr. (rough says that this beautiful Aphid seems confined to Upper Egypt. 

 There is great variation in the length of the proboscis in the larvae sent by him. 

 The marked wing ornamentation will separate it from other African Aphides 

 so far known. The neuration of the genus Dryaphis, formerly called Dryobius, 

 is very distinct from that of Lachnus. All the species have ornamented wings.

 times orange-brown behind. Head darker, and sometimes the pronotum also ; 

 two divergent dark lines of spots in the front part of the abdomen and two rows 

 of dark lateral specks, apex dark, with dark hair, almost black. Antennae pale, 

 dusky at the apex and on the apex of the penultimate segment : the fifth 

 segment is also sometimes dark. Legs fawn-coloured, pale, tarsi and apex of the 

 tibiae deep brown, base and apex or only the apex of the femora dark, coxae dark. 

 Antennae rather short ; the first two segments about equal in length, the first 

 somewhat the broader : the third the longest, equal to about the fourth and fifth 

 which are either equal in length, or the fifth a little longer than the fourth, the 

 latter with a large sensorium at the apex ; the sixth equal to or slightly longer 

 than the fifth, dark except just at the base, with a very short blunt nail, a large 

 sensorium at its base and two smaller ones below ; all the segments hairy, the 

 hairs especially long on the third to the fifth. Proboscis long and thin, very 

 acuminate, apex dark, reaching beyond the third pair of legs. Eyes large, dark. 

 Abdomen with short hairs all over ; Cauda rounded, black, with black hairs ; 

 seven dark spots surround the spiracles, with smaller ones between ; cornicles 

 short, slightly elevated and conical, surrounded by a dark area. Legs moder- 

 ately long, rather thick, apex of the tibiae and the tarsi dark, hairy, hairs densest 

 and longest on the outer side of all the segments. Length 2 to 2*3 mm.
