and mid tibiae testaceous, the hind one brown or infuscated, except 

 the tips which are sUghtly testaceous; tarsi whitish, the last joint 

 brown; marginal vein five-sixths as long as submarginal, stigmal vein 

 sessile ; veins yellow. Abdomen green with a bluish tint ; longer than 

 the thorax; first and second segments medially incised, the third with 

 only a slight incision. 



Tyye locality. — Washington, D. C. 



Host. — Diastroplius nebvlosus Osten Sacken. 



Paratype.—C&t. No. 25392, U.S.N.M. 



This species is redescribed from two female paratypes recently 

 received by the National collection from the Cambridge Museum of 

 Natural History, Zoology, and bearing the data " Type No. 812, reared 

 from Diastrophus nehulosus Osten Sacken." 



The male is described from a series of ten specimens bearing 

 No. 3762a;. 



Male. — Length 1.75 mm. Green but strongly fuscescent. Funicle 

 joints all wider than long except the first; coxae brownish, the hind 

 ones with a purplish tinge; femora and tibiae fuscescent. 



Distribution. — Washington, D. C. (Type). In addition to the 

 paratype received from the Cambridge Museum of Comparative 

 Zoology, the National collection contains 15 specimens. No. 3762a;, 

 reared from galls of a species of Cecidomyia, in the blossoms of Vernonia 

 novehoracensis Willdenow, collected by Mr. Pergande at Chain Bridge, 

 Va. One specimen reared from Oedaspes atra Loew on Solidago, col- 

 lected by J. C. Bridwell at Glen Echo, Md. Two specimens, Hopkins 

 No. 7223, reared September 16, 1907, from a gall on Solidago, col- 

 lected by E. J. Kraus at Seven Lock, Md. 



Callimome advena Osten Sacken resembles Callimome tricolor Huber, 

 from which it is easily separated by color. 



Except the type, which is reported from Diastrophus nehulosus 

 Osten Sacken, all other rearings reported have been from Cecidomyid 

 galls. Moreover, Osten Sacken in the reference cited above, mentions 

 five specimens reared from Asphondylia rudbeckiae conspicua Osten 

 Sacken by Jacob StauflFer, Lancaster, Pa., which he evidently thought 

 to be the same species he described. From all of the extensive 

 rearings from Diastrophus nehulosus Osten Sacken in later years no 

 specimens of Callimome advena Osten Sacken have been found. It 

 seems, therefore, that in view of this fact and also that the hosts are 

 quite different, that too much emphasis can not be placed on Osten' 

 Sacken 's record. 



One female of this species was reared, June 21, 1915, from the seeds 

 of Amelancheris canadensis (Linnaeus) Medicus, collected at North 

 East, Pa., by R. A. Cushman. Callimome amelancheris (Cushman) 

 was reared from the same lot of seeds. It is not known whether the 

 species is phytophagous or parasitic.
