and the simple claws. The species breed largely in flower buds

 Vpitntia. 



A. monacha O.S. Produces a small apical rosette gall on 

 Solidago lanceolata. It may also occur in an oval chamber 

 betw r een two adhering developing leaves, and has been reared 

 from dwarfed aster heads. Synonyms: .4. recondite O.S., A. 

 solidaginis Beutm. and .4. patens Beutm.

 \ an inch in diameter on Antennaria. Described as Asynapta. 



A. autumnalis Beutm. A globular, irregularly rounded bud

 2- inch. 



.4 . atriplicis Ckll. An irregular twig gall on Atriplex. Length 

 ^ inch, diameter \ inch. Described as Cecidomyia. 



A. conspicua O.S. Gall an irregular, subglobular enlarge- 

 ment some 2 inches in diameter, of the flower head of Rudbeckia. 



Schizomyia Kieff. 



Antennal segments 14, sessile or subsessile, the flagellate 

 ones in the male with remarkably stout, elevated circumfili; 

 palpi quadriarticulate ; the basal clasp segment of the male

 segments of the female much as in Asphondylia, the apical 

 portion of the ovipositor aciculate. 



5. coryloides Walsh & Riley. Gall a roundish mass 1 \ to 2\ 

 inches in diameter of from 10 to 50 opaque, woolly-pubescent,
