Kinsey: Studies of Cynipidse

duller-colored, of this gall will be confused with less distinctly 

 colored specimens of Disholcaspis plumbella Kinsey; both 

 species occur in enormous abundance on the same host, 

 Quercus dumosa; the adults of the two are very distinct. 



Disholcaspis simulata variety vancouverensis, new variety 



FEMALE. — Is distinguished from other varieties of the species as 

 follows: Head dark rufous, black medianly on vertex and face; an- 

 tennae rufous black, dark rufous basally; thorax rufous black, dark 

 rufous on the parapsidal grooves and forward, and on the mesonotum 

 basally, and dark rufous on the sides; lateral lines quite broad, broader 

 than in variety simulata; foveas of the scutellum more narrow, quite 

 rugose at base; abdomen piceous black, piceous rufous ventro-posteri- 

 orly; legs rufo-piceous, darkest on the tarsi; wings with veins piceous 

 black, heavier. 



GALL. — Mostly colored light buff to yellowish brown, in part tinged 

 rose red (not brick red!) when younger, weathering darker; on twigs 

 of Quercus garryana. 



RANGE. — Oregon: Roseburg, Grants Pass, Ashland. California: 

 Yreka. North of the other varieties. 



TYPES. — 2 females and 6 galls. Holotype female, paratype galls 

 at The American Museum of Natural History; paratype female and 

 galls with the author; paratype galls in Stanford University and the 

 U.S. National Museum, Labelled Ashland, Oregon; April 6, 1920; Kin- 

 sey collector. 



Tho structurally the two varieties are very much alike, 

 their distinct color, correllated with the distinct hosts and 

 ranges makes it important to distinguish two separated 

 tendencies in evolution. This variety is likely confined to the 

 geographic area of the more northern Pacific coast called 

 **Vancouveran" by Van Dyke (1919, Ann. Ent. Soc. Amer., 

 XII, p. 4) . Another variety occurs on Q. Douglasii in central 

 California, and still another distinct variety in the San Ber- 

 nardino Mountains, but I have not seen adults from galls of 

 these. 



Fleteroecus, new genus 



FEMALE. — Generally brownish rufous; antennae with 14 segments, 

 darker apically; parapsidal grooves not continuous; foveae large, more 

 or less rugose at base; second segment covering a large part of the 

 abdomen; tarsal claws strong, simple. HEAD: Not quite as vride as 

 the thorax, only slightly enlarged behind the eyes; rufous to dark 

 brown, dark about the mouth; finely rugoso-punctate, scatteringly hairy, 

 most so about the mouth. Antennae fairly stout, long, finely pubescent, 

 often darker on the seven or eight terminal segments, and lighter
