the radius rather heavy, angulate but without a projection or with a 

 very slight projection into the radial cell; areolet very large, larger 

 than in xeroijhila; cubitus distinctly discontinuous; radial cell open; 

 length 3.0-4.0 mm. 



MALE. — Very similar to the males of other varieties, differing as 

 follows: Parapsidal grooves very narrow, often indistinct or discon- 

 tinuous; median groove distinct, extending two-thirds the distance to the 

 pronotum; areolet large; cubitus discontinuous; length 2.5 mm. 



GALL. — Very similar to the galls of most varieties; generally 

 smaller, smooth, dark purplish brown, practically spineless. 



RANGE.— Utah: Brigham, Provo. 



TYPES. — 40 females, 11 males, 20 galls. Holotype female, paratype 

 adults, and galls at The American Musei^m of Natural History; paratype 

 adults and galls at Stanford University, the U.S. National Museum, the 

 Museum of Comparative Zoology, the Philadelphia Academy, and with 

 the author. Labelled Brigham, Utah; April 16, 1920; Kinsey collector. 



Of 55 individuals bred from galls collected April 16, 1920, 

 only 22, or 20 per cent, are males. This was probably due 

 to the males emerging mostly before the females. 



This variety comes very close to xerophila, but is distinct 

 in the nature of the parapsidal grooves, the breadth of the 

 thorax, and the nature of the gall, as well as in the means of 

 other characters. A discussion concerning the distinctness of 

 this variety is given under xeropliila.

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

 follows: General color dark rufous with some black, varying to wholly 

 black, usually very dark rufous to black; mouthparts and 

 a small area around the ocelli dark rufous; first and third segments of 

 the antennae brownish rufous, the second segment brown, remaining 

 segments black; thorax usually dark rufous with the lateral lines and 

 the anterior half of the area between the parapsidal grooves black; 

 median groove not prominent, extending only a very short distance from 

 the scutellum; mesopleurae edged with black, with a dark rufous central 

 area; scutellum dark rufous; abdomen light rufous anteriorly, ap- 

 proaching black postero-ventrally ; wing veins unusually heavy; areolet 

 moderately large or large; radial cell and surrounding area well shaded 

 with brown; radial cell more or less closed; first abscissa of the radius 

 unusually heavy, angulate with an indication of a projection into the 

 radial cell; length 3.0-4.0 mm.
