seen no intermediate females. Males intermediate to the subspecies 

 punicus are moderately common at high altitudes in the Sierra Nevada. 

 We and other collectors have found a number of them in Sonora Pass, 

 California, at about 8,500 ft. The females collected in Sonora Pass, 

 however, were all assignable to the subspecies punicus, though some 

 have extensive infuscation on the head and thorax to indicate a ten- 

 dency toward the subspecies relatimis. Also in other higher parts of 

 the Sierra Nevada there is a tendency for males to have the colors of 

 both subspecies relativus and punicus or to be intermediate, and for 

 females to be rather typical punicus. The only females truly inter- 

 mediate between relativus and punicus are one from Mount Adams, 

 Wash., collected July 24, 1921, by A. L. Melander (Cambridge) and 

 another from Agassiz, B.C., collected Aug. 22, 1921, by G. Glendenning 

 (Ottawa). In these, the head, thorax, and coxae are partly black, 

 partly fulvous or ferruginous.
