strongly produced on both sides. Relative length of antennal 

 segments III to VI indicated by 70, 40, 40, i2-(-65, III with 

 about 80 tuberculate sensoria. IV with no sensoria. IV to VI 

 slender. Cornicle about one-fourth longer than IV, with about 

 two-fifths its length with distal polygonal reticulations. Vein 

 A of fore wing about the length of cornicle. Cu nearly twice 

 as long. 



Apterous viviparous female : general body color as with the 

 alate female. Relative length of antennal segments III to VI 

 indicated by 65, 40, 40, i2-[-6o, III with about 40 tuberculate 

 sensoria. IV with no sensoria. Cornicle about as in alate 

 female. 



Apterous oviparous female : relative length of antennal 

 segments III to VI indicated by 57, 31, 31, n-f-58, III with 

 about 40 tuberculate sensoria. Hind tibia somewhat spindle 

 shaped and set with sensoria. 



This species was collected at Houlton, Maine on Solidago 

 September 10, 1907 when alate and apterous viviparous females 

 and apterous oviparous females were present. Both viviparous 

 forms were collected, also on Solidago, at Orono, July 9, 1912.

MACROSIPHUM EUEATORICOLENS N. SP. 



Alate viviparous female: general body color deep rose red 

 not like the red of most species inhabiting the Compositae, more 

 like the red of rosae but darker. Relative length of antennal 

 segments III to VI indicated by 60, 53, 50, 11+65, HI with 

 about 20 to 30 sensoria circular but 'not at all uniform as to 

 size. IV without sensoria. Cornicle as long' as III, sometimes 

 longer, with distal one-third reticulate. 



Apterous viviparous female: general body color as in the 

 alate female. Relative length of antennal segments III to VI 

 indicated by 55, 46, 39, 11 + 55, HI with 8 to 12 sensoria some- 

 what bunched on basal half. 



This is a common species on Joe-Pye weed, Eupatorium 

 purpureum L. Type (230-18) collected July 27, 1918 by Mr.
