APHIDIDAE OF PERSIA. 155 



vertex shows two short and two longer sUghtly capitate hairs. A few short blunt 

 lateral abdominal processes. Length, 1'5-1'8 mm. 



Alate viviparous female. 



Only imperfect specimens sent. Apparently dark and of reddish hue with dark 

 head, thorax, cornicles and cauda ; legs paler, with dark apices to tibiae and dark 

 tarsi ; two basal segments of antennae dark, third pale. The abdomen has dark 

 lateral and dorsal spots and the proboscis is pale towards the tip, but extreme apex 

 dark. The basal segment of antennae larger than second ; the third with 6-7 large 

 round sensoria in a line. Eyes large and deep reddish-black. The black cornicles 

 are cylindrical, shorter, but a little thicker than third antennal segment, slightly 

 expanding basally and not quite reaching the level of the cauda, markedly 

 imbricated. Cauda black, more than half the length of the cornicles, more or less 

 constricted near the middle, spinose, with long, fine hairs ; blunt apically. Anal 

 plate black, with long pale hairs. Wings large, venation normal. The abdomen 

 shows four small dark blunt lateral processes before the cornicles and one between 

 the cornicles and cauda. Length, 1*8-2 mm. 



Food-plant : Medlar (Mespilus). 



N. W. Persia : Enzeli, 29.iv.1919 (P. A. Buxton). 



Types in the British Museum. 



Described from several perfect apterous females, but both alatae damaged, 

 neither showing complete antennae. The sensoria on the third segment are marked. 

 The only other Mespilus species is Van der Goot's Myzus mespili, which is very 

 distinct. The vertex and lobes of the apterae and the basal segment of the antennae 

 approach to some extent those of the genus Phorodon, but in the alate stage it is a 

 distinct Myzus. It was found on the young twigs of the medlars, not doing much 

 harm. Ants were found in attendance. 



Aphis punicae, Passerini (fig. 3). 



A. punicae. Pass., Aphid. Italicae, pp. 32 et 42, n. 26 (1863). 



Alate viviparous female. 



Antennae shorter than body ; two basal segments dark and a dark area at apex 

 of fifth and around the sensoria on sixth, or all dark except base of third segment ;

basal segment wider but no longer than second ; third nearly as long as the sixth, 

 with 6-8 sensoria spread over its whole length, two frequently smaller than the 

 others ; fourth segment longer than fifth, the latter with the usual subapical 

 sensorium ; the sixth about as long as 4 + 5 ; fourth to sixth imbricated. Cornicles
