Aphid Food Plant Catalogue. 215 



"Intermediates" are frequent in the collections of this 

 aphid, which except for their wing stubs partake chiefly of the 

 characters of the alate female. 



MACROSIPHUM LANCEOLATUM N. SI'. 



Alate viviparous female : general body color dark reddish 

 brown, cauda yellowish white, cornicle black. Frontal tubercles 

 strong. Comparative length of antennal segments 111 to VI 

 indicated by 45, 38, 35, 10-55. M with about 30 sensoria scat- 

 tered along whole length. IV with no sensoria. Cornicle about 

 as long as IV and shorter than beak. Ill is shorter than vein 

 A of front wing. Reticulation of cornicle covering about dis- 

 tal two-sevenths. 



Apterous viviparous female : general color as in the alate 

 form. Ill with about 20 sensoria. Hairs of the head spatulate 

 at tip. Cornicle shorter than beak. 



This aphid is sometimes taken on goldenrod, Solidago lan- 

 ceolata L. The antennae seem particularly brittle and are fre- 

 quently knocked off at distal tip of III. The wings are often 

 sport-veined, M frequently being but once branched although 

 when branched twice the second branch is not especially near 

 wing margin. Mr. Pergande saw Maine material of this species 

 about fourteen years ago and stated that it was unnamed. The 

 writer has not succeeded in linking it with known species and 

 so describes it as new. 



The paratype material (43-05 and 86-09) is in the collec- 

 tion of the Maine Agricultural Experiment Station.
