4. ANDKENA. 59 



Male. Length 5 lines. — The pubescence on the clypeus white, 

 above which it is pale fulvous ; the cheeks have a long beard, and 

 the mandibles a fringe, of white pubescence ; the femora have a 

 fringe of the same colour ; on the tibia3 and tarsi it is pale fulvous, 

 the apical joints of the latter being pale ferruginous ; on the disk 

 of the thorax the pubescence is fulvo-ochraceous ; the wings as in 

 the female. Abdomen oblong-ovate, very glossy, the margins of 

 the segments depressed and narrowly rufo-testaceous ; the apical 

 segment pale testaceous. 



This very distinct species appears in July and August. I only 

 know one locality for it, viz. the chalk-pits at Northfleet, where 

 I have twice taken it. I have seen specimens from Alabama which 

 I cannot separate from it. The female most closely resembles that 

 of A. fulvescens ; but the longer abdomen, ' more narrowed both at 

 the base and apex, and its even and delicate close punctuation 

 serve to distinguish it ; the male has not the white clypeus as in 

 A. fulvescens.
