1911] Cynipidce of California 341 



Gall. Small, brown, cushion-shaped galls, sessile on twigs of 

 Quercus kelloggi and Quercus lobata, hard and woody with the base 

 broadly inserted in a slit in the bark. The top is flat and much pitted. 

 Length about 4 mm., breadth about 3 mm., height about 3mm. 



Habitat. Stanford University, Cal. (R. W. Patterson). 

 Sonoma County, California. (Beutenmiiller). 



Disholcaspis chrysolepidis (Bcutenm.) 

 Holcaspis chrysolepidis, Beutenmuller, Ent. News, vol. 22 (1911), p. 68. 

 Female. Very similar to D. eldoradensis, from which it can scarcely 

 be separated, except on the character of the gall. Specimens before me 

 show the following differences: parapsidal grooves deep and distinct, 

 reaching half-way to anterior margin, pubescence on the thorax 

 less abundant. 



Gall. Galls sessile on the twigs of Quercus chrysolepis and Quercus 

 dumosa and massed together around the stem, 15 to 30 in a mass; very 

 irregular but more or less cushion-shaped outwardly and rugose, 3-4mrn. 

 in diameter, this portion of the gall surmounting smooth, lobular 

 enlargements, sometimes arranged in a rosette. Sometimes the galls 

 are elevated or arranged palisade-like, the outer face rough, the sides 

 smooth, and with a median constriction. They are described as red- 

 dish or beef colored when fresh. Monothalamous, with a large internal 

 pupal cell. 



Habitat. Alma Soda Springs, Cal. (W. R. Dudley)- Placer 

 County, California. (Beutenmuller.) 



5 TRICHOTERAS Ashm. 



Trichoteras, Ashmead, Psyche, vol. 8 (1897), p. 67. 

 Trichoteras, Ashmead, Psyche, vol. Ill (1903), p. 150. 



Head and thorax closely punctate, opaque, and densely pubescent. 

 Antennas of female 12-scgmented, 3rd segment a little shorter and thicker 

 than 4th equal to 5th, succeeding segments to 9th becoming gradually 

 shorter, 9th to 11th only a little longer than thick, 12th as long as 10 

 and 11 together, Disc of the mesopleura bare, smooth and shining. 

 Scutellum cushion-shaped, a little longer than wide, with two smooth, 

 lunate fovea? at base. Tarsus of hind legs not longer than tibia, claws 

 with a tooth at base beneath. 



Trichoteras coquilletti Ashm. 



Trichoteras coquilletti, Ashmead, Psyche, vol. 8 (1897), p. 67. 



"Galls. Small, brown, sub-opaque, globular galls, averaging from 

 6 to <S mm. in diameter, and internally with a central kernel or larval 

 cell held in place by radiating filaments. 



"These galls were collected by Mr. D. W. Coquillett, at Los Angeles, 

 California, from the upper surface of the leaves of an unknown oak, 

 who forwarded them to the Department of Agriculture, where three 

 specimens of the gall-wasp were reared. Structurally and in general 

 appearance the galls very closely resemble Dryoplianta polita Bass., but 

 the sub-apterous wasp is quite different from that species.
