Andrena maderensis, n. sp. 



Female. Length about 12 mm.; very close to A.bimaculata Kirby, but differ- 

 ing thus: clypeus shining, with well separated punctures, smooth down the 

 middle; labrum fringed with shining red hair, and its process pointed; meso- 

 thorax posteriorly not distinctly punctate, and without a shining area: stigma 

 with a strong dark margin; nervures fuscous; second submarginal cell very 

 broad; area of metathorax less distinctly defined and less coarsely sculptured; 

 abdomen distinctly greenish, and first two segments without distinct punctures; 

 hair at apex of abdomen dark reddish; scope of hind tibiae redder, blackened 

 posteriorly. The dark chocolate facial foveae are like those of bimaculata. 



Male. Similar to A. bimaculata, but easily separated by the shining clypeus, 

 dark margined stigma, and other characters as in the female. 



Madeira, 4 9, 2 cf, in British Museum (T. V. Wollaston). 

 This was recorded by E. Saunders as A. bimaculata var? 



Andrena portosanctana, n. sp. 



Female. Like A. maderensis, and differing similarly from A. bimaculata, 

 but the thin abdominal hair-bands are white, without any fulvous tint, the apical 

 tuft is black; the wings are clearer, not so red; the hair of front and vertex 

 (but not occiput) is black, and on face dull white, but there is a conspicuous 

 reddish band from eye to eye at level of antennae; the discs of mesothorax 

 and scutellum have pure black hair, that on pleura is long and whke; the pro- 

 cess of labrum is more rounded, without a distinct point or tubercle; the clypeus, 

 though shining, lacks a distinct smooth median line. The greenish tint of the 

 abdomen is very obscure. 



Porto Santo, near the south side of the Pico do Castello, 

 January, 1921, at flowers of Oxalis cernua and Calendula 

 (Cocker ell}. 3 9. 



Andrena wollastoni, n. sp. 



Female. Like A . minutula Kirby, but area of metathorax dull and granular, 

 with sculpture hardly visible under a lens; mesothorax less punctured; stigma 

 larger and darker. 



Male. Recorded by E. Saunders from the Mount, Funchel (Eaton); the 

 specimens are in the British Museum. He remarks that they are apparently 

 minutula, a form with the mesonotum rugulose and with very distinct shallow 

 punctures, with the long-haired face characteristic of the first brood. 



Madeira; eight in British Museum; the females collected by 

 Wollaston. A. pusilla Perez, from Constantine, Algeria, is 

 very similar, and agrees in the sculpture of the metathorax, 

 but is easily separated by the more shining mesothorax. 



A single female, collected by my wife in Porto Santo, is 

 referred to A. wollastoni, though it is distinctly smaller and 

 otherwise slightly different. It was on flowers of Euphorbia, 

 north of the Villa Baleira, January 16, 1921. Possibly a series 

 would indicate a separate form.
