Kermes rimarum Ferris

Hosts: Quercus gambelii, douglasii, durata, garryana, lobata

Post-reproductive female. Ferris (1955b) described this species from slide-mounted specimens. His scant characterization of the post-reproductive female is as A small, dark species, its diameter not exceeding 2-5 mm. in any plane, variously shaped in conformity with the irregularities of its surroundings. Dark brown and displaying a small amount of secretion.

Remarks. Th is species has been recorded on five species of oaks in the western United States. Some of these records associated with first instars that have been identified by Dr. R. G. Baer as K. cockerelli Ehrhorn, do not differ from the two type specimens of K. rimarum.
