both sides of the leaves. This brood hatches from the eggs 

 which have been deposited in the leaf-scales of the buds and 

 the crevices of the bark the previous fall. The young lice are 

 predominantly green. 



Aphis ep.? Plate XI, fig. 62. 



Head black. Antenna3 black, with but few hairs ; length of 

 joints: I, 0.09 mm.; II, 0.07 mm. ; III, 0.54 mm. ; IV, 0.37 

 mm.; V, 0.28 mm.; VI, 0.14 mm.; VII, 0.63 mm.; total 

 length, 2.12 mm., being about the length of the honey-tubes 

 longer than the body. Sensoria circular, between forty and 

 fifty on the third joint, between fifteen and twenty on the 

 fourth, about ten on the fifth, the distal one being about three 

 times greater in diameter than the others ; six small and one 

 large at the distal end of the sixth. Eyes black ; ocular tuber- 

 cles small and not very prominent ; ocelli present but not very 

 conspicuous. Beak dark, 0.45 mm. long, extending to the 

 mesocoxse. 



Prothorax dark, cephalic border black ; thorax black ; wings 

 subhyaline, veins black, very robust, and margined with a very 

 faint smoky border not wider than the vein itself. Stigma 

 black, 0.14 mm. broad and 0.72 mm. long. Total wing expan- 

 sion, 6.40 mm. Legs all black except the proximal part, which 

 is sometimes brownish. 



Abdomen dark green, with four black spots on each lateral 

 margin. Honey-tubes black, incrassate, distal two-thirds di- 

 lated, 0.34 mm. long, being a little longer than twice the tarsi 

 in length, extending nearly to the distal end of the style. The 

 latter is black with a few long, spreading hairs ; also armed with

 in length. Total length of the body, 1.99 mm. 



This form was taken October 12, on the cultivated raspberry 

 {Ruhus occidental is) . It seems to be somewhat sporadic in habit, 

 since only a few were found at the time. Earlier in the season 

 a colony was found on the terminal stems of the wild raspberry, 

 but none were collected on account of their sudden disappear- 

 ance, due to a hard wind- and rain-storm. 



Aphis sp. Koch. Plate XIV, fig. 77. 



Head dark. Antcnnie a shade lighter in color, imbricated, 

 and almost bare ; length of segments : I, 0.07 mm. ; II, 0.05
