168 THE ENTOMOLOGIST. 



/3. Bright apple-green ; head dark ; eyes reddish brown ; two 

 basal segments of antennae dark, the third pale at the base, 

 remainder dark ; cornicles dusky, projecting a little beyond 

 the tip of the dark caudal process. Legs dusky green, 

 darker at the apices. Proboscis pale green, dark at the 

 apex, reaching just past the base of the second pair of legs. 

 y. Pale pink, with occasional ochreous areas. 

 In all the cornicles have marked transverse lines, and the third 

 segment of the antennae is longer than the fourth, the fourth 

 slightly longer than the fifth, the sixth about equal to the fourth 

 and fifth. Caudal process much as in the alate female (Fig. I., b). 



Nymph. — All pale yellowish green or pinkish to yellowish brown. 

 In some the head is pinkish, the thorax dull yellowish, and the 

 abdomen pinkish. Wing-buds dusky at the apices and sides. Legs 

 pale dusky at their apices ; antennae pale, dark on the apical half ; 

 cornicles pale, dark at their tips. 



I have retained Kalteubacb's name for this potato aphis, 

 although it certainly approaches Schrank's dianthi. The sen- 

 soria on the third antennal segment of the alate female nearly 

 agree with one another, but the general appearance of the insects 

 differ, and also the thoracic and' abdominal markings. More- 

 over, I could not get it to breed on peach or nectarine.
