ANTHOPHILA. 



(BEES.) 



CoIIetes fodiens, Kirb.— Rare. One female taken from a clay bank 

 overhanging the cliff at Glascarrig. 



C. Daviesana, Sm. — Scarce. A small colony in a cutting at the 

 Courtown brick and tile works. 



Halictus rubicundus, Ch. — Very common in the district. Males on 

 hawkweeds, females on Ragwort. 



H. cylindricus, Fab. — Fairly abundant, males especially, on thistles. 



H. villosulus, Kirb. — Not common. Taken at Glascarrig and Bally- 

 money. 



H. minutus, Kirb. — Rare. Occurred at Ballygarrett. 



H. nitidiusculius, Kirb.— Not common. Taken at burrows at Sea- 

 field and Pollduff. 



H. tumulorum, L,. — Pretty common, males at least. I was unable to 

 find any of the burrows of this and the next species. 



H. morio, Fab. — Also fairly abundant. Usually on hawkweed, Marsh 

 Marigold, and thistle. 



Andrena albicans, Kirb. — Abundant at Seafield and Ballymoney, 

 chiefly on bramble. 



A. Wilkella, Kirb. ) Common throughout the district. 



A. Trimmerana, Kirb. j ft 



A. nitida, Fourc. — Rare, taken at Kilmurray. 



A. f ucata, Sm. — Rare. One female at Ardamine and one on Taragh 



Hill. I have also taken this species at Skerries, Co. Dublin. 



Nomada altcrnata, Kirb. — Fairly abundant. The commonest of its 

 genus in the district. 



N. flavoguttata, Kirb. — Rare. At burrows of Andrena albicans at Bally- 

 money. 



N. bifida, Thorns.— Rare. Taker, at Pollshone. 



N. ruf icornis, L. — Fairly common. This pretty " cuckoo " bee seems 

 to be parasitic mainly upon Andrena Trimmerana. 



IYIegachile centuncularis. L,. — Common in the district in gardens. 

 Also about Wild Roses at Kilmurray and Kilbride. Burrows fre- 

 quently met with in Courtown Woods. 



Bombus tcrrestris, L. ) 



B. muscorum, L. > Very common and abundant. 

 B. hortorum, L. ) 



B. Iapidarius, L- — Very abundant. The commonest bee in the district. 

 Its nests are most common in sandy banks, usually deserted rabbit 



burrows. 

 B. syl varum, L. — Not common. In Courtown and Owennavarragh 



Woods. 

 I found an empty nest of Vespa norvegica in a small pine- 

 wood at Kiltennell, but I did not meet with the insect. No 

 species of Osmia occurred, but I discovered at Pollshone a 

 number of clay cells attached to a stone in the cliff, which I 

 think referable to one of these " mason" bees, perhaps Osmia 

 ruf a. For the determination of some of the more obscure 

 species I am indebted to the kindness of Mr. Edward Saunders, 

 FX.S., the well-known authority on this order, and Mr. G. H. 

 Carpenter ; and my best thanks are hereby tendered to both 

 these gentlemen.
