FRED. V. THEOBALD. 



in some specimens the basal two-thirds of the tibiae are pale. Antennae longer than 

 the body ; the first segment broader and a Uttle longer than the second ; the third 

 not quite as long as the sixth, with a Hne of 5 to 6 sensoria ; the fourth and fifth about 

 equal, the latter with a normal subapical sensorium ; the sixth a Httle longer than 

 fourth and fifth ; the third to the sixth imbricated, the flagellum of the latter annu- 

 lated, with a few small hairs. Cornicles darker green than rest of body, slightly

darkened at the tip, a Httle less than one-third the length of the body, slightly swollen 

 on the apical half, a few transverse lines on the apex, the rest faintly imbricated. 

 Cauda green, long and bluntly pointed, when exserted rather more than half the 

 length of the cornicles ; three pairs of lateral hairs, one curved subapical, one dorsal 

 and minutely spinose. Anal plate green. Proboscis short, not reaching the second 

 pair of legs, broad and dusky at the apex. The tibiae bear minute hairs. Length, 

 2 mm.

BhopalosipJium carduellinum, sp. n. ; 

 abdomen of alate $. 



Transvaal : Onderstepoort, 28.vii.14 {G. Bedford). 



Food-plant. Thistles (Carduus sp.). 



Described from two alate females and two apterous females, with many larvae 

 and two nymphae. In the latter the cornicles are shorter and rather thicker than 

 in the females and the wing-pads sHghtly darker than the rest of the body. I can 

 find no species agreeing with this insect and I have seen nothing like it on thistles, 

 except Walker's Aphis carduinum, which it certainly is not.
