Jaffa, accompanied by (parasite) Chrysis osiris, Buyss. Vide 

 Tr. Ent. Soc. Lond., Dec. 31, 1909, p. 468 : ligulicomis was 

 spoken of as a ' n. sp.' The Chrysid had been taken before 

 by Abeille du Perren in Egypt, also in snail-shells occupied 

 by another Osmia, viz. Vhotellieri, Perez, which likewise 

 occurs at Jaffa (' Memoires ' of Ent. Soc. Egypt, 1908, p. 38).

11. Osmia rufa, L. " The commonest British Osmia. 

 using all sorts of suitable cavities : pipes, key-holes, locks, 

 flutes, etc., have been recorded. Also in dead tree-trunks, 

 posts, rails, etc., and in the mortar of walls (nail-holes) or 

 in mud- walls. ' Cliffs and sancl-banks ' fide Smith. Said to 

 have been found in shells of Helix nem oralis, hortensis, and 

 pomatia in France, but I don't think it has been recorded 

 from snail-shells in this country. R,. C. L. P." 



' The most variable British Osmia in choice of situation 

 for its nidus. I have found it in holes in posts and occupy- 

 ing key-holes : a common site is the small lead overflow 

 pipe from the water cistern, which is a frequent source of 

 annoyance. If the bore is too large the bee will line it 

 with mud to bring it to the required size. When finished 

 the end is always well stopped with mud. A. H. H." 



Saunders includes snail-shells among the objects in which 

 the species builds (" Hymenopt. Acul. Brit. Isles "). 



12. Osmia rufigastra, Lep. (Algiers : Apr. 30, 1898). " Lepell. 

 de S. Fargeau says (' Hist. Nat. Ins.,' II, p. 324), ' Cette 

 espece est encore une de celles qui font leurs nids dans des 

 coquilles.' He says also (p. 322) of 0. tunensis, ' une de celles 

 qui font dans les coquilles du genre helices les nids que nous 

 avons decrits dans l'histoire des gastrilegides,' i. e. on p. 303 of 

 this same vol. II, ' Hist, Nat. Ins.' (Suites a Buffon). F. D. M." 



13. Osmia rufohirta, Latr. (Corfu : Apr. 22, 1901 ; Chiusi, 

 Central Italy : May 7, 1908). " The Chrysid Chrysis dichroa, 

 Dhlb., often occurs with rufohirta in snail-shells. Rufohirta 

 is one of the commonest and most widely distributed species 

 on the Continent, but is not British. F. D. M." 



The associated shell from Corfu was identified by Mrs. 

 Longstaft" and Mr. Robson as Pomatias (Cyclosto7na) elegans. 

 Miiller.
