ADDITIONAL HEARINGS IN CECIDOMYIIDAE 



By E. P. Felt, Albany, N. Y. 



The rearings of the last few months have assisted materially in 

 clearing up certain puzzles, and have done much to support our be- 

 lief in the taxonomic value of characters employed for the separation 

 of sub-families, tribes, genera and species in this group. The numer- 

 ous species of Cincticornia reared from galls on oak leaves force us 

 to the conclusion that this genus is practically restricted to Quercus, 

 while the many forms ot Caryomyia (a new genus erected, with Ceci- 

 domyia tuhicola 0. S. as type) obtained from galls on hickory leaves 

 compel us to believe that this group is peculiar to Carya. Further- 

 more, our rearings establish beyond all question the validity of the 

 recently proposed genus Sackenomyia, erected for a single female, 

 and enabled us to define not only both sexes but larvae and pupfe, and 

 to ascertain the life histories of two forms. The following brief char- 

 acterizations of the additional species reared and the galls they were 

 obtained from will suffice till more extended descriptions can be pub- 

 lished. 



Baldratia vesiculosa n. sp. was reared September 24, 1908, from 

 scattered, oval, green swellings, 2 mm. long, on the under side of 

 a blue-flowered aster leaf. The male is 1.75 mm. long, with uni- 

 colorous tarsi ; the abdomen mostly deep orange, segments 1 to 5 being 

 sparsely clothed with dark brown scales and narrowly margined with 

 a few white scales. Antennal segments, 14; palpi, uniarticulate. 

 Female 2 mm. long, with 15 antennal segments and a dark brown 

 abdomen, with submedian silvery spots. Type Cecid. al884. 



Baldratia dumosce n. sp. was reared July 30, 1908, from an incon- 

 spicuous yellowish brown blister gall taken by Miss Cora H. Clarke 

 at Annisquam, Cape Ann, Mass. Female 1.75 mm. long, with uni- 

 colorous legs, and the dark brown abdominal segments narrowly 

 margined with white. Antennal segments, 13 ; palpi, uniarticulate. 

 Type Cecid. al870a. 



Baldratia waldorfi n. sp. was reared in early May, 1908, from a 

 brown blister gall some 3 mm. in diameter, on the leaf of an unknown 

 hairy aster. Male 2 mm. long, the legs unicolorous and the dark 

 brown abdominal segments narrowly margined. The female with 18 

 and the male with 16 antennal segments, the palpi biarticulate. Type 

 Cecid. al824. 



Baldratia nitida n. sp. was reared April 17, 1908, from a yellowish, 

 smooth blister gall 6 to 7 mm. in diameter, on the basal leaves of aster.
