often a helpful character for males, but not a reliable one. In spite 

 of the epipleural differences and the assignment to different species 

 groups, C. varians and C. hesperus are very similar, and even females 

 of the two are sometimes difficult to distinguish. 



Type: 9, Fish Creek at 2,900 ft., Mount Rainier, Wash., Aug. 14, 

 1940, H. and M. Townes (Washington, USNM 63713). 



Para types (599) : From Arizona (near Alpine, Mount Lemmon in 

 the Santa Catalina Mts. at 7,800 ft., Oak Creek Canyon, and Parker 

 Creek and Workman Creek in the Sierra Ancha); British Columbia 

 (Kaslo and Robson) ; California (Crescent City, Cuyamaca Mts. in 

 San Diego Co., Donner Pass, near Glacier Point in Yosemite Park, 

 Inverness, Kernville, Laurel Beach in Lake Co., May Lake in Yosem- 

 ite Park at 10,500 ft., Muir Woods, Redwood Creek at Blair's Ranch 

 in Humboldt Co., Round Mt. in Shasta Co., San Jacinto Park at 

 7,000 to 10,000 ft., Snow Flat in Yosemite Park at 8,700 ft., Sonoma 

 Co., and Tamarack Flat in Yosemite Park); Colorado (Campus of 

 the University of Colorado at Boulder, near Estes Park, Fort Collins, 

 Greeley, and Steamboat Springs); New Mexico (Jemez Springs at 

 6,400 ft.) ; Oregon (Seaside and Silver Creek Falls in Marian Co.) ; 

 Washington (Elbe, Kalama River, Mount Rainier at 2,900, 4,200, 

 and 5,300 ft., Olympia, and Pullman); and Wyoming (Centennial). 

 In addition to females we have about 150 males that appear to belong 

 to this species, but since males are often difficult or impossible to 

 determine with certainty, they are not listed above. Most of the 

 males are from the same localities as the females. 



Most collecting dates are in June, July, and August, but the species 

 is on the wing from mid-spring to mid-fall. Unusually early and 

 late dates of capture are: April 19, 21, 26, 28, 29, and 30 at several 

 localities in the Sierra Ancha, Ariz.; October 6 at Inverness, Calif.; 

 and October 30 at Round Mt., Calif. We have found the species 

 often abundant among herbage in damp spots in forests. 



There is a single rearing record: 9, from Carpocapsa pomonella, 

 Fort Collins, Colo., C. P. Gillette. 



This species occurs from the Rocky Mountains to the Pacific, in 

 the Canadian and Transition zones. It is adult throughout the 

 growing season. 



9. Coccygomimus sanguinipes (Cresson)

 medium-sized female about 1.05 as long as basal width of mandible;
