gall is dry and old. Length, about 4 to 5 mm. Width on top, exclud- 

 ing the spines, about 4 mm. and about 1 mm. at extreme base at the 

 place of attachment to the leaf. . 



Habitat : Quail Flat, Tulare County, California, altitude 7,200 feet. J 

 Galls July 1, 1910. Flies March 23, 1911. Dr. Edwin C. Van ' 

 Dyke, collector. Several specimens of the flies and galls of this distinct 

 species were sent to me by Mr. Lewis H. Weld, who received them 

 from Dr. Van Dyke while they were collecting together in the mountains 

 of California. The species is allied to R. gracilis, from which it differs 

 in having the thorax less punctate and more shining and by having the 

 grooves more distinct. The female is unknown. According to Mr. 

 Weld the galls are densely clustered together in an indistinguishable mass 

 on a leaf, hiding the blade of the leaf completely. The greatly enlarged 

 illustrations were made by Mr. Weld.
