for their broods. The new growth twig was crowded with a 

 thick black encirchng mass. 



The apterous viviparous form is a plump, totally huckle- 

 berry black with a slight white bloom of wax powder. The 

 nymphs are reddish brown to black. The pupal nymphs (Col- 

 lection 25-13) were black with wax area of "bloom" on abdo- 

 men except central median longitudinal path which was with- 

 out wax, wing pads and thorax dirty green. 



The winged female has head and thorax slate black, abdo- 

 men with dorsum reddish black and margin slate black, cauda 

 black and cornicles short and black. 



The accompanying figures characterize the wing and an- 

 tennae, the conspicuous thing about the latter being the short- 

 ness of the spur of VI. 



Macrosiphum spirae;cola n. sp. (97-10.) 



(Figure 91, A. Figure 96, K.) 



A species which I do not feel justified in ascribing to any- 

 thing already named, I took on Spiraea Van Houttei, on the 

 Maine Campus, August 20, 19 10. The apterous females with 

 their nymphs were present, but I have not taken the winged 

 form. The color varieties were vermillion, bright green, yellow 

 green, rose pink, and lemon yellow. The young nymphs had 

 the same range in color. 



One of the vermillion specimens chosen for the color descrip- 

 tion is recorded as follows : head vermillion, antenna with I and 

 II pale. III dark, eyes black, beak Avith first joint pale and 

 third dusky; prothorax and thorax vermillion; femora and 

 tibiae pale brown, tarsi black; abdomen with the slightest 

 bloom, vermillion with mid-dorsum and lateral margin deeper 

 than the rest; cornicles long, clavate, light brown with tip 

 black; cauda vermillion. The accompanying figures give the 

 antennal structures and the cornicle. 



Note. The drawrngs of antennae and cornicles accompanying this paper 

 are all done to the same scale and given the same reduction.
