Dec, I9I2.] FuLLAWAY: CALIFORNIA GaLL-FlY PARASITES. 281 



minvite punctures, each puncture enclosing a hair, mesopleura behind and 

 abdomen smooth and shining, microscopically reticulate. Head broader than 

 thorax, extremely thin anterior-posteriorly, the ocelli on the vertex arranged 

 in an obtuse triangle, a groove extending outwardly from these to eyes, which 

 are small and convex, face between wide and sunken in middle, cheeks not very 

 broad, separated from face by a well-defined groove, antennae 7-jointed (scape, 

 pedicel, i ring-joint, 3-jointed funicle and an undivided club), inserted at 

 lower level of eyes, scape not quite as long as funicle, longer than club, which 

 is somewhat expanded, the individual funicular joints and pedicel subequal. 

 Parapsidal grooves on mesonotum distinct, a median groove posteriorly and 

 four longitudinal grooves on scutellum, which is more or less truncate behind, 

 followed by a thin post-scutellum. A median carina on metanotum bifurcating 

 at about middle forming two large fields above. Abdomen short oval, depressed, 

 concave in dry specimens, hind margin hairy, ovipositor not exserted. Legs 

 fairly long, hairy. 



Metallic green, legs lemon yellow outwardly from middle of femora, tips of 

 tarsi black, eyes red, mandibles reddish brown, antennae yellowish brown, some- 

 what infuscated. Wings hyaline, marginal vein as long as submarginal and 

 fairly thick, stigmal vein short and the club capitate with a spur, postmarginal 

 vein extremely short and pointed, (^ antennae clothed with long hairs and tip of 

 abdomen with a short brown spur. 



From gall of Diplolepis echina O. S. 



Described from i $ and 3 d" specimens in Coll. L. S. J. U. (Lot 

 508, s. 19). 



T. stanfordiensis, new species. 



Female. — Length 2.10 mm., expanse of wings 4 mm., greatest width of fore- 

 wing .85 mm. Very similar in habitus to preceding but with fewer punctures 

 and less hairy. Abdomen elongate, pointed at apex ; median line on mesonotum 

 extending the whole length of same. 



Metallic green, tips of femora, tibiae and tarsi yellowish brown to sordid 

 white ; antennae fuscous brown ; stigmal vein in wing longer, with distinct spur. 



From pimply gall on Quercus douglasi, from which no gall-flies 

 were bred. 



Described from one ? specimen in Coll. L. S. J. U. (Lot 497, s. 8). 



There were also among the parasitic material two Pteromalids 

 apparently belonging in the tribe Pteromalini ; also an extremely 

 interesting single male Torymid, apparently running to the genus 

 Oligostheiuts Forst., black, metallic, rugose and hairy, with hairy 

 eyes, a rather long stigma and a dusky spot below on disc, but the 

 material was either insufficient or in too poor condition for 

 description.
