This, one of the earliest known species, is easily recognized by 

 the white tarsal bands, especially broad on the posterior legs. One 

 of the commonest forms, it breeds in several species of Solidago 

 and aster. The females are abroad in June and presumably may be 

 found ovipositing during a considerable period, since they occur 

 in greater or less numbers from then till September or even into 

 October. This species occurs upon a variety of Solidago, namely 

 S. graminifolia, S. sempervirens, S. serotina and 

 S. canadensis. It has also been reared from aster. 



Osten Sacken in 1875 proposed the name of A. recondita 

 for an Asphondylid pupa protruding from an arrested budlike growth 

 on aster taken at Lloyds Neck, N. Y., in September. Our rearings 

 practically establish the identity of this pupa with the species under 

 discussion. Professor Beutenmueller, basing specific characters 

 largely upon the type of the gall, described this species as A. s o 1 i- 

 d a g i n i s and again as A. patens. An examination of the 

 type of the latter shows that the peculiar tarsal banding given in 

 the original characterization is evidently an error, since the specimen 

 agrees in every particular with A. monacha. 



Gall. This species produces a variety of deformations. The 

 most typical one in the vicinity of Albany occurs on the narrow- 

 leaved goldenrod, Solidago graminifolia, is apical, sub- 

 globular, rather firm and from 1 to 1.5 cm in diameter, tapering 

 distally and with the apical third consisting of rather closely ap- 

 pressed leaves. It resembles very closely the gall produced by 

 Oedaspis polita Loew. During midsummer the female may 

 deposit eggs between the leaflets of a partly developed bud of Sol- 

 idago serotina or S. canadensis and thus produce
