compressed, and as seen from the side rather strongly arched in the 

 center; first four segments medially incised. 



Male. — Length 2.6 mm. Antennae with all joints, except the last 

 two, distinctly longer than wide and of equal width; scape brownish; 

 tibiae brown, the hind ones fuscous. Abdomen with first segment 

 green, the others purplish brown. 



Tyye locality. — California. 



Host. — Probably gall on Castanopsis chrysopJiylla by Andricus 

 castanopsidis Beutenmueller. 



TyjJe.—C&t. No. 25337, U.S.N.M. 



This species is described from 7 males and 16 females under Bureau 

 of Entomology No. 3791^ and reared from "large, globular, brown" 

 galls, presumably collected by A. Koebele in California; exact data as 

 to the locality is not available. The galls were not in situ when 

 found. The adults emerged from November 16, 1885, to January 8, 

 1886. Also nine specimens under Koebele No. 320° and reared 

 from galls on Quercus lohata collected August, 1890, at Glen Ellen, 

 Sonoma County, Calif., by A. Koebele; two specimens under Koebele 

 No. 549° and reared from galls on Quercus dumosa collected October, 

 1889, in Sonoma County, Calif., by A. Koebele; one specimen under 

 Koebele No. 688, reared from a gall on Quercus dumosa collected 

 February 20, 1891, in the Santa Cruz Mountains, California, by A. 

 Koebele; three additional specimens from Sonoma County, Calif., 

 under Koebele Nos., 544°, 545°, and 109°. The type, allotype, and 

 35 paratypes are in the United States National Museum, and a male 

 and female paratype (Bureau No. 3791^) in the author's collection. 



Attention is called to the fact that the host cited for the types was 

 not determined. The description of the gall of Andricus castanop- 

 sidis Beutenmueller is somewhat similar to the description of the 

 galls from which the parasites were reared.
