 appendage. Palpi; first segment short, the second one-half longer,

Parallelodiplosis clarkeae Felt

A number of the yellowish males and females were reared Sep- 

 tember 19, 19 10 from a narrow, clustered, apical, bud gall on 

 Spiraea salicifolia collected in August 1910 by Cora H. 

 Clarke at Magnolia, Mass. This species appears most closely allied 

 to C. pratensis Felt, though it is easily separated by the broadly 

 emarginate lobes of the dorsal plate. It is possibly an inquiline. 



Gall. Length 7 mm, diameter 3 mm. This appears to be some- 

 what intermediate in character between the chestnut burr gall and 

 the ordinary bud gall observed upon this shrub. The aborted 

 leaves in this gall are slender, numerous, somewhat approximate 

 and present a superficial resemblance to the fringed or chestnut 

 burr gall.
