the rest of the segment is rugosely transversely punctured. 

 The propleurse have a dense curve of pale fulvous hair ; 

 the propleurae below and at the junction with the meso- 

 pleurae are widely furrowed, the furrow being transversely 

 keeled. Legs thickly covered with pale hairs, which 

 are darker on the hind legs. Wings clear hyaline ; the 

 nervures fuscous; the second cubital cellule at the bottom 

 as long as the third; the first recurrent nervure is received 

 very shortly beyond the middle ; the second in the apical 

 third of the cellule. Abdomen shining ; the segments 

 above and beneath lined with white depressed hair ; the 

 basal segment with a deep, wide, longitudinal furrow. 



The present species agrees very closely with A. reti- 

 culata, but it may be known from it by the deep furrow 

 on the basal segment of the abdomen, by the large 

 shining, deep depression at the middle of the median 

 segment ; which in A . reticulata is smooth, shining, and 

 without any depresion. 



Andrena mephistophelica, sp. nov. 



Long. 11 — 12 mm. 



Hab. Mussouri (Rothney). 

 Is related to A . sczvissima ; but may be known from it 

 by its smaller size ; by the much stronger and closer 

 punctation of the clypeus ; by the hairs on the median 

 segment being much longer, closer and fulvous in colour, 

 differing from the hairs on the mesonotum, which are 

 much paler. 



Head, except on the clypeus, covered thickly with 

 long hairs, pale beneath, darker on the front and vertex. 

 Clypeus with large punctures, which are much sparser 

 on the apex, its apex being almost clear of them and 

 fringed with dark fulvous hairs ; the base of the mandibles 

 aciculate. The antennae almost bare ; the flagellum from 

 the second joint brownish beneath. Pro- and meso-thorax
