Insects, 1929 



burrow in the level ground, particularly in sandy situations : I do not 

 remember ever to have detected it burrowing in sloping banks, which 

 many of the species of this genus usually prefer. 



Sp. 68. Andrena fuscata. 

 Melittafuscata, Kirby. 



Female. — (Length 4j lines). Black; the pubescence on the face 

 fulvous, on the vertex it is fuscous ; the antennae beneath slightly pi- 

 ceous. Thorax, on the disk the pubescence is fuscous, and fulvous 

 on the sides and on the metathorax laterally; the tegulae nigro-piceous ; 

 the wings hyaline, slightly clouded at their margins ; the legs beneath 

 are nigro-piceous, their pubescence very pale fulvous, as is also the 

 floccus ; the scopa fulvous ; the tarsi dark ferruginous. Abdomen 

 sub-ovate, convex, shining, and finely punctured ; the margins have a 

 pale or white marginal fringe, the anterior broadly, and the second 

 generally, more or less interrupted. 



Male. — (Length 4 lines). Black ; the face has a fulvous pubescence, 

 that on the thorax is more inclining to pale fuscous ; the wings hya- 

 line, iridescent, and slightly clouded at their apical margins ; the legs 

 are clothed with a similar pubescence to that of the thorax ; the claws 

 ferruginous. Abdomen oblong-ovate, shining and finely punctured ; 

 the margins of the segments, excepting the first, have a pale or some- 

 times white fringe. 



This species closely resembles the A. Afzeliella, but it differs in 

 having black posterior tibiae ; otherwise I can point out no distin- 

 guishing marked character. This bee is abundant near London, and 

 appears to be generally distributed. I have seen specimens captured 

 in Wales, Scotland, and the Isle of Wight. This species appears in 

 May, and sometimes I have met with it in April. 



Sp. 69. Andrena Afzeliella. 

 Melitta Afzeliella, Kirby. 



Female. — Length 4 J — 5 lines). Black ; the clypeus nearly naked, 

 a little pale fulvous pubescence on each side along the margin of the 

 eyes ; the antennae black. Thorax thinly clothed on the disk with 

 pale fulvous pubescence ; the metathorax fringed on each side with 

 pale fulvous ; the tegulae nigro-piceous ; the wings sub-hyaline, the 

 apical margins slightly clouded ; the pubescence on the legs is pale 

 fulvous ; the posterior tibiae and tarsi, the intermediate tarsi, and api-
