﻿AMERICAN CYNIPID GALL WASPS — WELD 321 



shorter than thorax, twice as long as high. Length 2.25-3.25 mm. 

 Average of 43 specimens 2.92 mm. 



Differs from Z>. julgens (Gillette), the median groove of which is 

 as distinct as a parapsidal in posterior third and whose propodeum is 

 rugose medially. 



T'y/je,?.— U.S.N.M. No. 60108 : Type female, allotype, and 20 para- 

 types. Paratypcs also in A.M.N.H., C.M.N.H., A.N.S.P., C.A.S., 

 M.C.Z., and C.'u. 



Host — Rosa sp. 



Gall (pi. 17, fig. 17). — A large abrupt "root" gall at the crown, up 

 to 50 mm. in diameter, surface somewhat botryoidal. 



Habitat. — The types are from galls collected at Ojai, Calif., on 

 April 6, 1922. They contained pupae at that time. Adults emerged 

 April 26 to May 20, Galls were seen also at St. Helena and Los Gatos.

DIPLOLEPIS POLITA (Ashmead) 



Rhodites polita Asun^mAD, Colorado Biol. Assoc. Bull. 1, pp. 14, 38, 1890. 

 Rhodites occidcntaJls Beutenmuelleb, Brooklyn Ent. Soc, vol. 17, p. 45, 1922 

 (new synonymy). 



Ashmead described polita from a gall similar to the eastern Diplo- 

 lepsis hicolor (Harris) , found on Rosa calif ornica., but adds the state- 

 ment that he has seen galls from Dakota and Colorado also. As the 

 types in the U. S. National Museum are from Marin County, Calif., 

 and bear Koebele's label wnth No. 70 in red ink, the type locality is 

 California, and i\\'^ Dakota and Colorado material was misdetermined. 

 There are males of this species in collections from Los Angeles but not 

 marked as types. 



Fullaway reared adults, which he determined to be Rhodites hicolor 

 (Harris), from Cupertino (Stevens Creek), Calif., and described them 

 in 1911 (Ann. Ent. Soc. Amer., vol. 4, p. 377) . In 1922 Beutenmueller 

 gave this hicolm' Fullaway the name of Rhoditis occidentalis. The 

 U. S. National Museum has a female specimen from Cupertino (Stev- 

 ens Creek) which must be a type of the Fullaway description. It 

 agrees with types of R. polita Ashmead. It measures 3.1 mm. The 

 5 nmi. measurement in the description must be a misprint for 3 mm.
