the evidence does not warrant a positive statement. The nearly 

 free third and fourth antennal segments indicate a relationship to 

 the European Baldratia and Stefaniella, while the triarticulate 

 palpi show a connection with Lasioptera. Despite these anomalies 

 we have tentatively referred the species to the above named genus. 



Gall. This simply shows as a rounded, greenish spot on the 

 upper side of the yellow leaves in the fall. The lower epidermis 

 is slightly raised. The solitary whitish larva in the gall has a length 

 of 2 mm. 



Asteromyia reducta Felt 



191 1 Felt, E. P. Econ. Ent. Jour., 4:481 



This species was reared in considerable numbers from an irregu- 

 larly oval, blackish blister gall with a diameter of about 4 mm on 

 Aster undulatus. The material was collected at Mag- 

 nolia, Mass., July 26-28, 19 10 by Cora H. Clarke. 



Gall. Diameter 4 mm, irregularly oval, blackish. 



Asteromyia sylvestris Felt 

 1915 Felt, E. P. Can. Ent., 47:228-29 



The yellowish or brownish blister leaf galls of this species were 

 very abundant October 22, 1914 on Aster cordifolius at 

 Mount Kisco, N. Y. This species is most easily distinguished from 

 its near allies by the reddish brown or brownish black abdomen, the 

 biarticulate palpi and the 16 antennal segments in both sexes.

This species was reared at Albany August 10, 1907 from a yellow- 

 ish or brownish, oval blister gall on the leaves of Aster 

 paniculata. A species of Polygnotus was reared. 



Gall. The blister gall producing this form is irregularly oval, 

 about one-quarter of an inch in diameter and is yellowish or brownish, 

 the upper surface sometimes light brown, irregularly encircled 

 with yellowish white; the under surface is a nearly uniform, yellowish 

 white. The gall is distinctly thicker than the normal leaf, it pro- 

 jecting about equally on both surfaces. For a colored illustration 

 see Museum Bulletin 175, plate 1, figure 14.
