Heteroecus sanctae-clarae variety fuscior new variety 



FEMALE. — Differs from the other varieties of the species as fol- 

 lows: Antennae distinctly light yellow rufous basally; thorax rich, dark, 

 brownish rufous, distinctly black on the anterior parallel and lateral 

 lines in the basal depression of the scutellum; depression at base of 

 scutellum more rugose at bottom; most of mesopleurae finely and more 

 regularly puncto-aciculate, very distinctly edged with black; abdomen 

 dark rufo-piceous, almost black dorsally, yellow-rufous ventro-posteri- 

 orly; second segment covering more than three quarters the abdominal 

 area ; wing veins light yellowish brown ; areolet of moderate size, smaller 

 than in the other varieties; first abscissa of the radius not infuscated; 

 length 2.5-2.7 mm. 



GALL. — Does not differ particularly from the galls of the other 

 varieties. 



RANGE. — San Jacinto Mountains, Pasadena. Probably thruout the 

 southern Sierras and their extensions, except in the San Bernardino and 

 Cuyamaca ranges. 



TYPES. — 2 females and 16 galls. Holotype female, paratype galls 

 in The American Museum of Natural History; paratype female and 

 galls with the author; paratype galls at Stanford University, the 

 Museum of Comparative Zoology, and the U.S. National Museum. La- 

 belled San Jacinto Mountains, California; February 28, 1920; Kinsey 

 collector. 



The insects had all emerged before the collecting in Janu- 

 ary and February. 



Heteroecus sanctae-clarae variety aliud, new variety 



FEMALE. — Differs from the other varieties of the species as fol- 

 lows: Thorax rich, dark, rufous brown, distinctly black on the anterior 

 parallel and lateral lines, in the basal foveas of the scutellum, and on 

 the edges of the mesopleurae; depression at base of scutellum distinctly 

 smooth at the bottom; most of mesopleurae finely and more regularly 

 puncto-aciculate, similar in this regard to fuscior, more heavily edged 

 with black, especially ventrally, than in fuscior; abdomen dark rufo- 

 piceous, almost black dorsally, dark brownish rufous ventro-posteriorly ; 

 second segment covering about two thirds of the abdominal area, about 

 as in variety sanctx-clarx rather than in fuscior; wings with veins 

 light brown, darker than in fuscior, distinctly lighter than in sanctx- 

 clarse; areolet of moderate size, rather larger than in fuscior; first 

 abscissa of the radius with an indication of a limited infuscation, less so 

 than in sanctx-clarx; length 2.7 mm., intermediate in size and build 

 between the other two varieties. 



GALL. — Does not differ particularly from the galls of the other 

 varieties. On Quercus chrysolejns. 



RANGE. — San Bernardino Mountains. Probably confined to this 

 range.
