1901.] 7 



To Mr. Edward ISauuders, F.L.S., I am indebted for the identi- 

 ficatiou of the greater portion of my captures, all the specimens 

 having gone through his hands. I have already had the occasion of 

 personally thanking Mr. Saunders, when he spent an afternoon with 

 me in Glasgow, but must also embrace this opportunity of again 

 expressing my gratitude, not only for the identification of my captures, 

 but for the very great interest which he has undoubtedly taken in the 

 matter. 



The weather during these two seasons, as every one knows, has 

 not been of the finest description, but full advantage was taken of 

 the intervening fine days ; and I am not altogether displeased at the 

 result. The following is a list of the principal captures : — 



Fompilus Ktiguicularis, Thorns.— One $ on flower heads of yarrow, King's 

 Cross, Arran, August 18th. 



Oxyhelus uniglumin, Linn. — Several near Irvine, June 30th to July 22nd, on 

 wild carrot. O. mandibularis, Dhlb. — Earo, near Irvine, July l-ith, on similar 

 plant (three spocimens). 



Odynerus spinipes, Linn. — One S, Dundonald, July 14th. Mr. Anderson 

 Fergusson also brought me from Barr 2 (J s and a ? . 



Prosopis brevicornis, Nyl. — One ^ and four ? s, Irvine. July 22nd. 



Halicius tumKlorum, Linn. — da very common at King's Cross, on knapweed, 

 August 15th. 



Andrena Cetii, Sehr.--One $ swept from birch, and two ? s on scabious, Aug. 

 4th — 8th, at King's Cross. 



Nomada ochrostoma, Kirb. — One ? , Barr, Ayrshire, in 1898, Mr. Anderson 

 Fergusson. N. Fabriciana, Linn. — One, King's Cross, August 13th, near burrows 

 of Andrena Q-wynana. 



Epeolus productus, Thorns.— One specimen, Irvine Moor, July 8th, 1899 ; and 

 another at same locality, July 22nd last ; this little species will doubtlessly be 

 parasitic on Colletes montanus. 



I can find no previous Scotch record for any of the above. The 

 following are rare in Scotland, but have all been recorded : — 



Fompilus xpissus, Schiodte. — One J , Dundonald, Ayrshire, July 14th. 



Crabro tibialis. Fab. — One S , Dundonald, swept from birch, July 14th. 



Colletes montanus, Mor. — This species, which I had the luck to add to the 

 British list last year, and which was described by Mr. Saunders, ante vol. xxxv, 

 p. 262, I again found this season very commonly from June 30th to July 22nd, at 

 Irvine. 



Andrena cineraria, Linn. — One ? taken by the late Mr. Geo. W. Ord at 

 Strathbano, June, 1899, and a S from Pirnmill Arran, June this year, by Mr. A. 

 Fergusson. 



Nomada obtusifrons, Nyl. — One c? and five ? s at King's Cross, Arran, on 

 August 13th, at a spot where Andrena coitana was abundant. 



Bombus Jonellus, Sm.— One ?, Irvine Moor, July 8th, 1899; Luss, June 2nd,
