AFRICAN APHIDIDAE — PART II. 125 



sensoria over its whole length, mostly on one side ; fifth segment shorter than the 

 fourth, with one large sub-apical sensorium and a smaller one below the middle ; sixth 

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

 flagellum ; the fourth to sixth imbricated. Proboscis rather long and thin, reaching 

 to the base of the third pair of legs ; apical segment dark, rather narrow and pointed 

 and longer than the penultimate segment. Cornicles rather short and cyhndrical, 

 faintly imbricated, a httle longer than the cauda, which is bluntly cone-shaped, with 

 two pairs of lateral hairs and shghtly spinose, pale brown, darker at the edge ; anal 

 plate brown, hairy ; two large round pores on the segment in front of the cauda, with 

 a distinct hair on the outside of each. Femora and tibiae hairy. Length, 2-5 mm. 



Apterous viviparous female. — Pale ; head and pronotum bright brown ; abdomen 

 with transverse lines of small black specks and with broad brown median bars 

 between the cornicles down to the tail ; cauda small, pale, with dark brown edge ; 

 cornicles, legs and antennae brown, the tibiae being paler ; proboscis thin, pale, 

 except at the apex, reaching just past the second pair of legs, up to the third pair. 

 Antennae less than half the length of the body ; the basal segment much wider than 

 the second, the third the longest ; the fourth less than half the length of the third, 

 and longer than the fifth ; sixth as long as the fourth and fifth, its base less than one- 

 third the length of the flagellum ; third segment paler than the others. Proboscis 

 as in the alate female. Legs rather thick, especially the femora ; femora and tibiae 

 hairy. The brown cornicles shghtly expanding at the base, imbricated, longer than 

 the cauda. Cauda brown apically, spinose, with two pairs of lateral hairs and one sub- 

 apical dorsal one ; anal plate brown, spinose and hairy. The segment in front of the 

 cauda with two large median pores and a hair on the outer side of each, and two 

 similar but smaller pores on the next segment. Length, 2*5-3 mm.

Food-plant. Artichoke (Cynara). 



Described from a series of spirit specimens and shdes. This species fives in the 

 flower-heads of the globe artichoke. It might equally well be placed in Siphocoryne, 

 except for the cornicles. The pores on the apical part of the abdomen are very 

 marked. The colour cannot be given. 



Aphis punicella, sp. nov. (fig. 19). 



Alate viviparous female. — Head black, slightly shiny ; eyes broA\ii. Antennae 

 with two basal segments black ; third pale at base, rest black ; fourth, fifth and sixth 

 black. Pronotum black, green in front and behind ; thoracic lobes black and shiny. 

 Abdomen green to dark green ; cornicles black, with a conspicuous dusky area on 

 the middle and slightly posterior to base of each cornicle ; three prominent lateral 

 black spots in front of the cornicles ; cauda yellowish green. Insertions of wings 

 yellowish ; costa smoky ; cubitus pale yellow ; stigma smoky. Legs ochreous, 

 apical half of third femora dusky ; apex of first to third tibiae black ; tarsi black. 

 Anal plate dusky ; sternal plate black. Head with small frontal processes, raised 

 in the middle ; two median incurved capitate hairs and one on each lobe curved 

 outwards. Antennae shorter than the body ; the basal segment a little wider, but 

 no longer than the second ; the third a little shorter than the sixth, with 6-9 sensoria 

 over its whole length ; the fourth a little shorter than the third and a little longer
