 as long as the fourth and fifth, its basal area one-third the length of the flagellum ; 

 third to sixth imbricated. Proboscis reaching to near the second coxae, acuminate, 

 the apical segment longer than the penultimate. Pronotum with a blunt papilla 

 on each side. Cornicles long, but shorter than the third antennal segment, striate 

 at the base, becoming imbricate and then practically unadorned at the apex. Cauda 

 about half as long as the cornicles, with three hairs on each side. Anal plate with 

 six prominent long hairs and a few others. Legs with pale hairs. Length, 1 "2-1 '5 mm. 

 Apterons viviparous female. — Pale yellowish-green to green ; head dull yellowish 

 green ; eyes broT\Ti. Antennae with the two basal segments of the same colour 

 as the head ; the third pale ochreous, with smoky apex ; the other segments

 little longer than the fourth, with 4-5 sensoria ; fourth a little longer than the fifth, 

 the latter with the usual sub-apical sensorium ; the sixth a little shorter than four

 segment, imbricated. Cauda about half as long as the cornicles, blunt, with three 

 hairs on each side and shghtly spinose. The dark anal plate with three marked 

 long hairs on each side. Legs shorter and thicker than in the alate female ; apices 

 of the tibiae prominently overlapping the basal tarsal segment on one side ; tibiae

Food-plant. Pomegranate (Punica granatum). 



Described from spirit specimens sent me by Mr. Willcocks and his colour notes 

 on this species. The apterae are very distinct, the third antennal segment having 

 sensoria. The curious cowl-like ends to the tarsi, especially to the hind tarsi, are also 

 very characteristic. The cephalic hairs are fine, short and slightly capitate.
