collecting the galls out-of-doors : March 30 at Placerville, 

 April 3 at Dunsmuir. Galls collected in the Yosemite Valley, 

 at a high elevation, while snow still buried most of the small 

 trees, were quite immature on March 26. These Yosemite 

 Valley insects belong, without doubt, to this variety rather 

 than to eriophorus, the variety of the southern Sierras. 

 Eriophortis occurs at El Portal, not twelve miles from the 

 Yosemite Valley, but at an elevation which is a thousand feet 

 lower, and in a locality not nearly as exposed to the severe 

 climate of the higher Sierras. The Yosemite Valley belongs 

 to one faunal area. El Portal to another!

FEMALE. — Differs from the female of other varieties of the species 

 as follows: Parapsidal grooves extending hardly half the length of the 

 mesonotum, almost wholly smooth at bottom; median groove lacking or 

 extremely short; basal fovea; of the scutellum darkened but not black, 

 largely rugose at the bottom, with only small, smooth areas ; first ab- 

 scissa of the radius arcuate, with only a slight suggestion of an angle ; 

 length 2.5 mm. (-3.2 mm., acc. Kieffer) ; averaging distinctly smaller 

 than in variety dasydactyli, larger than in pygmseus. 



GALL. — Very similar to that of variety pygmasus. Each gall short, 

 ovoid or less often spindle-shaped, w4th the tapering point short, not 

 usually curved as in pygni^us, more or less smooth. Usually singly, 

 sometimes a few in a cluster, on twigs. 



PvANGE.— California: El Portal; Clareniont (Baker); Upland, 

 Pasadena, San Jacinto Mountains. Probably occurs thruout the southern 

 Sierras and their extensions, south of El Portal, except in the San Ber- 

 nardino and Cuyamaca mountains. 



TYPES.— Berlin Museum? Pomona College? Material from the 

 same collector (Baker) and the same locality (Claremont) at Stanford 

 University. 



This variety comes very close to variety pygmxiis, but the 

 insects can be separated by the darker rufous brown general 

 color, and by the rugose bottoms of the fovese of eriophorus. 

 Pygmxus comes from a neighboring but isolated mountain 

 range. I have not seen types of this variety, but Dr. Mc- 

 Cracken very kindly compared types of pygnixus with Baker
