In regard to the number of generations in this locality, it appears that there is 

 one in June or earlier and one in July. The first eggs were found early in June, and 

 gravid females were observed in nature as late as July 24, 1907. Although these 

 two generations are all that were observed occurring on Rvmex, yet my observations 

 were not extensive enough to say that there were not. earlier or later ones. 



I am under obligation to Mr. Eugene Amandus Schwarz, U. S. National IMuseum, 

 for identification of the species. 



NOTES ON HARRIS'S TYPES OF CYNIPIDAE. 



BY WILLIAM BEUTENMIJLLER, NEW YORK CITY. 



Through the kindness of Mr. C. W. Johnson, I was enabled to examine the 

 types of the species of C^mipidae described by the late Thaddeus William Harris, 

 whose collection is in the Boston Society of Natural History. 



Rhodites semipiceus {Harris). 



Cynips semipiceus Harris, Rep. Ins. Mass. Inj. Veget. 1841, p. 400; Treat. Ins. 

 New Engl. Inj. Veget. 2nd edit. 1S52, p. 436; Treat. Ins. Inj. Veget. 3rd edit. 1862, 

 p. 549; ibid. New Edit. Flint, 1862, p. 549; ibid. 1863, p. 549; ibid. 1880, p. 549. 



One gall and one female adult are in the collection. The head and abdomen of 

 the specimen are wanting, but from the remaining parts and the characteristic gall, 

 the species may be recognized as being the same as Rhodites fulgens Gillette. Harris's 

 species was heretofore erroneously considered to be a guest-fly (Periclisfis semipiceus) 

 of Rhodites radic2tm> by the late R. von Osten Sacken. 



The type gall is very similar to the one I figured in the Bulletin of the American 

 Museum of Natural History, Vol. XXIII, 1907, plate XLVI, fig. 2. The galls may be 

 found at or on the roots of Rosa rubiginosa, Rosa humilis, Rosa Carolina and probably 

 other species of wild roses. 



Rhodites bicolor (Harris).
