swollen and dark at base and apex, greenish-brown in the middle, 
shiny, rather long, the apex with some reticulation. Cauda rather 
small, acuminate, pale brownish-green, slightly spinose with three 
pairs of lateral cheetze. Legs shiny, long and thin, pale brownish- 
green, dusky at apices of femora and tibia and with dusky tarsi; 
tibiz sometimes pale greenish-yellow. Venter paler brownish-green, 
shiny. In some specimens the dark brown areas are almost black 
and the whole insect has a general shiny dark appearance, until 
examined under a lens. The antenne, which arise from large frontal 
processes, have the basal segments much larger than the second; the 
third a little longer than the fourth, with 3-4 basal sensoria; fourth a

Food Plants.—Cultivated tulips and violets. 
Localities—Swanley, 14th November, 1913; Canterbury, 
9th-28th February, 1914; Goudhurst, 10th March, 1914. 
I first found this Aphid at Swanley, and later in a nursery 
at Canterbury, where many apterous females were scattered 
about on tulips under glass, and again on violets in frames. Here 
and there the plants were covered with the young, which were 
bright green or yellow, mostly feeding inside on the upper sur- 
face of the leaves, but now and then belowthem. The young 
are very sluggish, but the apterous females run about rapidly, 
especially when the food supply is becoming low. I obtained 
the alate females from the same nursery on February 24th. 
They soon became busy depositing green young. I noticed that 
the lice from the apterous female were mostly yellow and thus 
easily told from those produced by the alate female. The alate
