and very shining, the extreme base of the impressions finely and 

 remotely punctured, the apices slightly discoloured, and of a some- 

 what bronzy-brown colour, apical fimbria brownish-golden, segments 

 beneath clothed with very long hairs, eighth ventral segment sub- 

 truncate, its stem densely fringed towards the apex with long hairs, 

 making a fan-shaped expansion, regarded sideways slightly elbowed, 

 armature with rather elongate straight stipites, their basal angles only 

 slightly produced. 

 Long. 9-10 mm.

In appearance closely resembling the ^ of nycthemcra 

 and of Jlorentina, but the shorter antennse and very different 

 armature distinguish it at once from the former and the 

 white hairs and the absence of black velvety pubescence 

 at the base of the abdominal segments from the latter.

I am indebted to Professor Perez for this information. 



Andrena albohirta, n. sp. 



(^. Niger, dense albido hirsutus, antennarum flagello, abdominis 

 segmentorum apicibus, tarsorum apicibus venisque alarum testaceis, 

 abdomine ruguloso, opaco. 



Black, entirely covered with whitish hairs, erect on the head and 

 thorax and more or less adpressed towards the apex of the abdomen, 

 apices of the segments, the flagellum of the antennje beyond the 

 2nd joint, the nervures of the wings and the apices of the tarsi pale 

 testaceous. Second joint of the flagellum as long as the 3rd and 4th 

 taken together, 3rd much longer than the 2nd. Mesonotum shining, 

 biit so hidden by the hairs that its surface is hardly visible, abdomen 

 as seen between the hairs finely rugulose, the apices of the segments 

 bearing a dense apical band of white hairs, apical fimbria ochreoua, 

 abdomen beneath with bright golden apical fringes, 8th ventral valve 

 slightly widened at the a^^ex, subtruncate, its stem rather narrow, 

 with a fringe of short hairs along the sides, armature with the lobes 

 produced into very strong teeth. I communicated this species to 

 Professor Perez, who returned it to me as allied to his A. farinosa. 



Long. 7-8 lines.
