however [in Not. Sallsk. Faun-Flor. Fenn. 2. (Rev. Syn. 

 Ap. Bor.) p. 234 (1852)], points out that in Linne's de- 

 scription of annulata the bases of the $ antennae are said 

 to be marked with w T hite, which is not a character of 

 communis, and also that in the Linnean Collection (now at 

 Burlington House) the only specimen ticketed by Linne 

 himself as annulata is not a communis, but belongs to the 

 species which Nylander had formerly [in Not. Sallsk. Faun- 

 Flor. Fenn. 1. (Adnot. Mon. Ap. Bor.) p. 188 (1848)] named 

 in error *dilatata K. and afterwards [in Not. Sallsk. Faun- 

 Flor. 2. (Suppl. Ap. Bor.) p. 94 (1852)] re-named borealis. 

 The latter has the scapes conspicuously marked with 

 white ; and as, accordingly, Linne's supposed " type " 

 agrees with his original description there seems no reason 

 to doubt its authenticity, in which case borealis Nyl. 

 and not communis Nyl. should be sunk as synonymous 

 with annulata. (Borealis and communis being both species 

 of Nylander's own making, it is particularly unlikely that 

 his decision on this point should be erroneous !) 



Page 420, line 28. " Type 3 : Andrena bicolor F." 

 Andrena bicolor F. is identified by most recent authors 

 except Schmiedeknecht (e.g. F. Smith, Thomson, E. 

 Saunders, and v. Dalla Torre) with the summer genera- 

 tion of Andrena gwynana Kirby. But the latter has the 

 abdomen clothed more or less with pale brown hairs, also 

 in the <$ the legs are pale-haired, and the scopae of the $ 

 are fulvous. 



Fabricius has described his species at least four times, 

 and always in the same words : — " A. thorace villoso 

 ferrugineo, abdomine atro immaculato " ; and short 

 though this description is, it seems clearly to indicate not 

 the bicolor of recent authors, but the Andrena which we 

 have been accustomed to call thoracica F. Rossi in Fauna 

 Etrusca, after quoting Fabricius's diagnosis, goes on to 

 say " Staturafere A. mellificae. Tota atra, thorace tantum 

 superne saturate rufovilloso. Abdomen glabrum nitidum. 

 Alae apice fuscae, praesertim primores." This is a most 

 excellent description of our " thoracica," and seems to 

 make it certain that Rossi identified bicolor F. with that 

 species, and not with the bicolor of Smith, etc. Panzer 

 and Christ have both given coloured figures of bicolor, 

 and the figure by Panzer is accepted by Fabricius in 

 Sy sterna Piezatorum as representing his species. Now in 

 both these figures the pilosity of the legs is represented
