All the species in the first Section appear to be parasitic upon 

 wild bees, and are, therefore, generally found in the vicinity of their 

 burrow^s or nests. 



C. BTJCCATA, Fall. 



This, tlie typical species of the group, has the face very prominent, of a silky- 

 ■white or yellowish colour. The eyes are sub-contiguous in both sexes, though slightly 

 wider apart in the females than in the males. The antennae are small and short, 

 especially in the females ; the third joint being but slightly longer than the second. 

 The arista is thickened at its base, almost bare in the males, but pubescent in the 

 females. The thorax is whitish-grey, with the sides almost white ; it is indistinctly 

 striped. The abdomen is whitish-grey with black reflections, and an interrupted 

 longitudinal dorsal stripe ; it is cylindrico-eonical, with small inflexed pale grey anal 

 segments in the male, and ovoid, with pointed apex, in the female. The wings have 

 the external transverse veins oblique, and slightly sinuous. The legs have the pos- 

 terior tibiae almost bare on their inner sides. 



This species is of local occurrence. I captured several in May, 1881, on a piece 

 of rocky ground at Silverdale, in Lancashire, near the burrows of some wild bees. 

 I caught two of the bees while entering their holes, and on submitting them to Mr. 

 Bridgraan, he kindly named them as Audrena albicans and Andrena fulva.
