268 THE ENTOMOLOGIST. 



I have obtained the small dark variety of the worker of 

 this species from a nest taken at Walraer : this form appears 

 to be common in Sweden and Denmark, and would probably 

 occur in Scotland, but is very rare in the South of England. 

 The typical examples of senilis and pygmaeus have been 

 examined by that accurate observer Dr. Nylander, so that 

 no doubt can arise of their identity with this species. Found 

 in all parts of the country.

 Tills species I at one time was led to consider, judging 

 from the terms of the description, and also from the exami- 

 nation of a specimen in the Banksian collection, to be the 

 "senilis "of Fabricius ; but, as I have already shown, that 

 insect is. on Dr, Nylander's authority, a mere faded example 

 of B. Muscorum. Under these circumstances 1 have thought 

 it best to retain the name used in ray book on the ' British 

 Bees.' Found in all parts of the country.

 This species was discovered in Shetland by Mr. Adam 

 White, where it has subsequently been taken by the late Mr. 

 Squire, and recently, in abundance, by Mr. Rich : it is 

 closely allied to the B. arcticus of Dahlbom, but, having 

 obtained that insect from Prof Schenck, of Nassau, and 

 having had a series from Copenhagen forwarded by Mr. 

 Drewsen for examination, I am satisfied of thdr being distinct 

 species : the pubescence that clothes the body of B. arcticus 

 beneath is pale; in B. Smithianus it is black. 1 have ob- 

 tained the nest of this species containing all the sexes. Only 

 hitherto found in Shetland.
