in April, and sometimes as early as the end of March, and may be

82. R. nodulosus, y{^\(\.=^hederae , Curt. Generally distributed, 

 appears in May, and may be met with to October. 



83. Molophilus ater, Meig. ^brevipeniiis, Curt., Brit., Ent., figure. 

 This is a fairly common species on the moors of the north of England 

 and Scotland, but is rare in Dorset, being found by my father on 

 Knighton Heath, on July 13th, 1839. 



84. M. murinus, Meig. Fairly common by the side of shady 

 ditches in May and June. This is a difficult species to preserve as 

 the down on the wings rubs off so easily. This and the last are the 

 two smallest British species of the family. 



85. M. obscurus, Meig. Abundant on rushes throughout the 

 summer. 



86. M. pvopingitus, Kgg. —vnssipes, Curt., Brit., Ent., figure. — 

 Common in shady places from June to September. It is of an 

 ochreous colour. 



87. M. appei'idiculntus, Staeg. Occurs on Poole Heath in July. 

 It is smaller than the last and is more of a feruginous than ochreous 

 colour.

ANDRENA. 



The females of this large genus burrow 10 to 12 inches deep in the 

 ground in various situations, some in vertical banks, some in sloping 

 undulations, and others choose fiat and hard-trodden pathways. 

 Their tunnels branch out in all directions below the entrance, and are 

 usually rougher and mucli less finished internally than those of 

 previous genera. Most of the species, such as A. fidvicvus, albicvus, 

 labialis, and coitana, are gregarious, a few burrow ap;rt.
