NEW AND LITTLE KNOWN BRITISH APHIDES. 231 
females and nymphex. One apterous female occurs on one slide, 
but I do not think is mature. The antenne have only five 
segments. This species is quite distinct from any Anuraphis I 
know of. 
Thripsaphis cyperi, Walker. 
Oviparous female.—Apterous. Light brown, the anterior portion 
of the body frequently lighter and more of a greenish brown; the 
divisions of the segments all yellow, with their margins less defined 
on the sides, where the yellow area is wider on each segment; the 
segmental divisions are also marked with dark lineal streaks. 
Cornicles as small yellow pores. Apex of body tipped with brown. 
Antenne blackish brown. Legs brown. Eyes dark red. Venter 
yellow. Body with a few very short hairs, only seen under the 
microscope. Usually a pale undefined line in the middle of the 
anterior segments. Antenne of six segments; from a little under to 
a little over half the length of the body; basal segment much larger 
than second ; third longer than fourth ; fourth about half the length 
of third and equal to the fifth, the latter with a small pale subapical 
sensorium ; sixth longer than fifth, the basal area nearly as long as 
the flagellum. Eyes large, no ocular process. Proboscis thick, not 
quite reaching to the second coxe. Legs thick and rather short ; 
hind tibiz with many pale sensoria, not quite reaching to the apex. 
Cauda somewhat quadrangular at the swollen extremity, with a few 
short hairs. Anal plate retracted, bilobed, with a few short hairs. 
Length, 1:8 to 2 mm. 
Larval oviparous female-—Smaller and browner than mature 
female. Yellow, with brown areas and brown spots and dots. 
Cornicles as yellow pores, in centre of a brown spot. Legs and 
antenne brown. Like the adult covered completely with white 
tomentum. The antenne more than half the length of body ; basal 
segment larger than second; third nearly twice as long as fourth ; 
fourth and fifth equal; sixth longer than fifth; basal area longer than 
flagellum. Proboscis very broad, reaching just past second coxe. 
Legs short and thick; tibie with a few short stiff hairs. Cauda 
triangulate at knobbed end. 
Apterous viviparous female.—Hlongate and more Thrip-like than 
the oviparous female. Antenne about half the length of the body, 
proportions same as in oviparous female. Proboscis reaching just to 
the second coxe. Cauda markedly knobbed, the apex rounded. 
Anal plate bilobed, lobes widely separate, with a few bristles. Hind 
tibiz narrow, narrower than the fore and the mid, all with numerous 
short hairs; one marked cheta on each small first tarsal segment, 
shorter ones on the second tarsals. Cornicles rather more raised 
than in the oviparous females. 
Length, 2 mm.
