FEMALE. — Differs from the female of other varieties as follows: 

 Color generally dark rufous brown to rufo-piceous ; antennae black with 

 the first three segments rufous; median groove distinct for more than 

 two-thirds the mesonotal length; scutellum rufo-piceous, a brighter 

 rufous area centrally; abdomen rufo-piceous, in part blackish; areolet 

 of moderate size; first abscissa of the radius slightly angulate, some- 

 times with a very short but distinct projection; radial area open; length 

 3.0-3.7 mm. 



MALE. — Very similar to the males of other varieties; wholly black; 

 median groove distinct for two-thirds the mesonotal length; areolet 

 moderately large; radial area open; length 3.2 mm. 



GALL. — Veiy similar to the galls of the other varieties; relatively 

 small, smooth, more free of spines. 



RANGE.— Colorado: West Cliff, Colorado Springs (Cockerell); 

 Manitou (Kinsey). Records from other regions of Colorado, or from 

 other states, very probably do not apply to this variety. 



TYPES.— Not located. Type locality is West Cliff, Colorado. 



The above description was made from an adult from ma- 

 terial collected at Colorado Springs by Prof. Cockerell, and 

 from the insects and galls collected at Manitou. This variety 

 is probably restricted to a region in Colorado on the east of 

 the Continental Divide, but we do not have material enough to 

 determine the limits of the distribution. Utah galls, figured 

 by Beutenmuller, and refigured by Felt, belong to variety 

 tumida.

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

 follows: Head rufous brown with dark shading between the compound 

 eyes and the mouthparts, and dark shading on the vertex and the 

 posterior side of the head; first three segments of the antennae light
