66 The Scottish Naturalist. 



A. ti'immerana. — Common on dandelion at Lochar Moss and 

 Dalscairth. Most of the ^ s captured have the pubescence on the 

 face black. Mr Smith describes specimens from Loch Rannoch 

 as also having this peculiarity. 



A. lapponical — In June 1877 I captured two specimens on 

 ragwort — one at Mabie, the other at Corberry Hill, localities five 

 miles apart — which Mr E. Saunders thinks are this species; and as 

 A. Iapp07iica was first discovered by the Rev. Mr Little at Moffat, 

 not far from Dumfries, this is very probably the correct name. 



A. nigj'iceps. — Found at Dowie Vale in a '" sod dyke." 



A. deuticiilata. — Not uncommon, and is generally distributed 

 over this locality. Frequents the dandelion and ragwort in 

 August. 



A. albicnis. — There is a colony of this species at the Craig's 

 Quarries, but I have not met with it elsewhere. 



A. coitana. — Very abundant. Mostly found on hawkweed and 

 ragwort. 



A. paiinila. — Very common. In April and May almost every 

 dandelion flower has one or sometimes more of this little bee 

 upon it. 



A. viinittula. — I have taken about a dozen of both sexes of 

 this species, but was quite unable to distinguish it from A. parvula 

 until Mr Saunders did so for me. All were, however, taken in 

 August, when the latter had long disappeared. 



A. nana.—\ captured a few of this species in July last at Dal- 

 scairth by sweeping the heather flowers. 



A. cojivexiti scuta. — The only one I have taken of this — a $ 

 from dandelion in May 1878 at Dalscairth — was stylopised. 



A. xanthuj'a. — Several were captured in Lochar Moss in 1877, 

 but I did not find it last year. It frequented ragwort flowers. 



Halictus rubicundus. — The season of 1877, which brought 

 forth the wasps and humble-bees in such unusual swarms, must 

 have had a deterrent efl'ect upon this species. All summer I did 

 not see more than half-a-dozen of it, although in 1876 and 1877 

 it was extremely abundant. 



H. cyliiidricus. — Very common ; perhaps the most abundant 

 bee of the district. Wherever there is a dry and firmly-trodden 

 footpath, there its colonies are sure to be found. 



//. atbipes. — Mr Saunders separated this species from amongst 

 a number of H. cylindricus which I sent for examination. I 

 confess I am quite unable to see any specific distinctions. Both 

 are apparently equally common here.
