This species was first taken by Doctor Patch on August 20, 1910, 

 on the ventral side of the leaves of Spiraea van houttei at Orono, Me. 

 The collection consisted of apterous viviparous females and nymphs. 

 On July 11, 1916, she took a single alate female with young, and 

 apterous females with young on Spiraea salicifolia at Orono, Me. 

 There is in the National Museum a single sHde containing two 

 Apterous viviparous females. These were taken by A. N. Caudell 

 at Kaslo, British Columbia, June 23, 1903, on Spiraea species. I 

 know of no other collections. 



Cotypes. — Deposited in the collection of the Maine Agricultural 

 Experiment Station — apterous No. 97-10, alate No. 84-16.
