BEES OF THE FAMILY ANDRENIDAE— TIMBERLAKE 375 



older and worn specimens show little or no evidence of this sub- 

 fasciate condition). Face, including clypeus, closely punctured. 

 Frons finely, substriately rugose. Thorax dull, the mesonotum 

 with small, close punctures. Sides and posterior face of propodeum 

 finely rugose, the sculpture finer than that of basal area. Abdomen 

 finely, moderately closely, and rather weakly punctured. Tergite 

 2 depressed a little less than one-half. Basal process of labrum 

 much broader than long and broadly concavo-truncate at apex. 

 Third antennal joint as long as thick at apex and about one- 

 half as long as following joint. Flagellum dull. Length 8-9 mm.; 

 anterior wing 6.8-7.8 mm. 



The male of this species is similar to that of A. quintiliformis 

 Viereck, but has the antennae slightly longer, mesoscutum duller, 

 with finer, less separated punctures, and abdomen hardly fasciate 

 and less strongly and less densely punctured.

ANDRENA (TRACHANDRENA) CALIFORNICA WICKHAMI, new subspecies 



At first glance the hair on the hind basitarsus of wickhami 

 appears to be light colored, but careful scrutiny shows that it is 

 actually darker than the scopal hair of the tibia. This subspecies, 

 therefore, shows some similarity to A. grandior Cockerell but 

 differs in having the mesonotum duller and densely punctured, 

 the abdomen less densely punctured, with the basal impression 

 of tergites 2 and 3 less strong and the basal elevation of each
