sheath of ovipositor projecting upward obliquely to line of tergum. Legs 

 pubescent. Wings hyaline, pubsecent, veins fuscous, distinct, radial 

 cell short, closed, vein at base slightly arcuate, areolet distinct, cubitus 

 not reaching basal vein. Length 2.5 mm. 



Male. Similar to female, but antenna? 14-segmented, 3rd segment 

 basally emargined, parapsidal grooves in many specimens apparently 

 complete, pubescence more or less sparse. 



Bred from galls of Rhodites politus on wild rose (Rosa 

 calif or nica). 



Habitat. Pt. Arena, Cal. (Miss Mabel Patterson.) 

 Very similar to P. californicas, but apparently distinct.

 and sheath of ovipositor brown or brownish. Head smooth and. shining 

 on occiput, vertex and front to insertion of antenna?, face radiately 

 striate and pubescent, pubescence extending on to genae, antenna' 

 13-segmented, 1st and 2nd segments stout, 1st obconic, 2nd globose, 

 3rd segment long, as long as 1 and 2 together, following segments progres- 

 sively shorter to last, which is considerably longer than penultimate; all 

 the segments more or less pubescent, distally from the middle infuscate. 

 Pronotum wide in the middle, aciculate at the sides, pubescent, meso- 

 notum smooth and shining, parapsidal grooves complete, rather widely 

 separated at scutellum, median longitudinal lines and smooth lines over 

 base of wings distinct, mesopleura transversely aciculate and shining, 

 scutellum evenly rugose, basal foveas oblique, oval, with smooth shining 

 bottom, contiguous, separated by a median carina, metanotum rugose 

 and bare. Abdomen smooth and shining, dorsally depressed, 2nd tergite 

 reaching more than half-way to apex, 3rd tergite rather broad, oviposi- 

 tor slightly protruding. Legs pubescent. Wings hyaline, pubescent, 

 faintly iridescent, veins brownish, radial cell open at the margin, vein 

 at base almost straight, areolet distinct, cubitus reaching basal vein. 

 Length 3 mm. 



The male has 14-segmented antennas, of which the 3rd segment is 

 basally emargined. 



Gall. Large galls surrounding the stem of the thimbleberry [Rubus 

 nuikanus), 25-60 mm. long and 12-25 mm. in diameter. Polythalamous.
