44 BRITISH APHIDES. 



Winged viviparous female. 



Smaller than the larva. Fine green. Head olive 

 and somewhat broad. Neck and thorax robust. 

 Thoracic lobes and scutellum dark olive. Abdomen 

 green, with a slight yellow carina. Cornicles long and, 

 like the legs and tail, pale green. Tips of the tibiae and 

 the tarsi dark olive. Stemmata on the occiput obvious, 

 as also are two depressions behind the eyes. Rostrum 

 reaches to the third coxae. Eyes bright red. Wings 

 with rounded apices. Cubitus and stigma yellowish 

 green. Yeins brown. These are liable to abnormal 

 variation somewhat similar to that shown in PI. LY, 

 fig. 4, where three furcal veins appear on one wing, 

 and in PI. LXXXIV, fig. 3, where the cubital nervure 

 has a furcation in excess. 



Found pretty numerously at Wanstead, on the 

 spruce-fir, Pinus ahies, from the middle of May to the 

 end of November. Specimens were kindly sent to me 

 by Mr. Walker. 



I believe that this is the only known British Aphis 

 belonging to that section of the Aphidinse which has 

 seven antennal joints, and finds its food on a conifer. 



The pupa is entirely green, with short antennse. 

 This insect does not appear in the lists of Kaltenbach, 

 Koch, or Passerini.
