Diplolepis tuberculatrix variety versicolor, new variety 



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

 as follows: General color rufous brown with black, the rufous dis- 

 tinctly darker than in calif ornica ; head black, with a narrow, rufous 

 brown patch extending from the bases of the antennae to the mouth and 

 with a rufous brown patch extending from the borders of the eyes up- 

 wards and covering the vertex at both sides and behind the ocelli; first 

 three segments of the antennas brown to black, remaining segments 

 black; thorax rufous brown with the anterior parallel lines and lateral 

 lines rufous to black (generally darker than the remainder of the 

 thorax) ; median groove evident only a short distance from the scutellum; 

 anterior parallel lines quite distinct; mesopleurae black with a rufous 

 central area; scutellum dark rufous to brown; abdomen rufous an- 

 teriorly, shading into black posteriorly; areolet moderately small; first 

 abscissa of the radius angulate without a projection; cubitus apparently 

 continuous; radial cell distinctly open; length 3.0 to 4.0 mm., but of a 

 distinctly smaller build than calif ornica. 



MALE. — Not available for description. 



GALL. — Closely resembles that of calif oimica. 



RANGE. — Oregon: La Grande. Probably occurs thruout Oregon 

 east of the lava bed elevations, and in adjacent parts of Idaho. 



TYPES. — 6 females, 9 galls. Holotype female, paratype galls at 

 The American Museum of Natural History; paratype females and galls 

 at Stanford University, the U.S. National Museumi, and with the 

 author. Labelled La Grande, Oregon; April 12, 1920; Kinsey collector. 



Collections at La Grande on April 12, 1920, showed all of 

 the males emerged, and only a few of the females were still 

 in the galls. The females, as with other varieties, appear to 

 emerge somewhat later than the males. This variety is most 

 closely related to oalif ornica. It occurs in a barren country 

 which is entirely separate from western Oregon, and distinct 

 from central California Avhere calif ornica occurs.
