This is a local and very beautiful species ; it is remarkable for 

 having its antennas longer than is usual in these insects. For- 

 merly I used occasionally to meet with a specimen or two on 

 Hampstead Heath about a colony of Andrena albicrus^ but they 

 have long disappeared from that locality ; a few years ago, a 

 colony of Andrena longipes was discovered at Highgate, accom- 

 panied by this species in abundance, both having been previously 

 scarce. The latter locality is on the London side of Highgate 

 Archway, to the west of the high road.

Female, Length 3 lines. — Pale rufous ; the ocelli enclosed in a 

 transverse black patch, which does not pass beyond them ; from

 margins of the clypeus ; the cheeks are also black, the tips of 

 the mandibles rufo-piceous. Thorax : the disk has three 

 black lines passing from the collar to the scutellum, the central 

 one broadest ; the sides of the thorax behind the wings black, 

 the metathorax and scutellum usually of a paler red than the 

 disk ; the breast has a black stain in front ; the legs red, the 

 femora with a fuscous stain at their base beneath ; the wings
