Macrosiphum rubicola Oestlund. 



(Figure 94, A-C.) 



An alate female with 8 nymphs was collected from the ven- 

 tral leaf of wild red raspberry, August i, 1906. This had head 

 bluish black dorsally and ventrally pale green, antenna blackish 

 except proximal III, eyes black; prothorax bluish black dor- 

 sally, and ventrally green; marked transversely with pale green 

 at membrane and space cephalad thorax; tubercles distinct; 

 thorax with lobes glistening bluish black, lateral portion pale 

 green with two black patches, ventrally green, wings clouded 

 at apex inclosing distal portion of Rs, stigma very dark ; abdo- 

 men glabrous medium green, cornicles brownish black, cauda 

 pale green. 



The individual described is evidently darker than those 

 Doctor Oestlund saw. Some specimens taken at the same 

 time here ran lighter. These aphids were taken on ventral 

 leaves and on stems. Maine collections; 92-06, 34-08, 158-12. 



SPIRAEA, 



Aphis spiraecola n.n. 



(Figure 91, B-C. Figure 96, J.) 

 This species is certainly close to pomi and may possibly be 

 a variety but it does not seem safe to place it with that species 

 at present. It is recorded by Professor Gillette as Aphis 

 spirceella Schouteden (1910). The antenna is practically the 

 same as with pomi. The cornicles in the winged form are 

 shorter than any pomi I have taken. 



Aphis spiraephiea n. sp. 



(Figure 91, D-F. Figure 96, I.) 

 The most common and constant species for native Spiraea 

 salicifolia is the one I am recording as a new species after 

 collecting it for ten years. It apparently spends its whole 

 cycle on the same food plant, as the colonies have been taken 

 from May to August. A collection made May 31, 1913, con- 

 tained the stem mother still active and her mature apterous and 

 alate progeny, the latter settling like the former on the Spiraea
