Bignell his informafton and led him to go to Slapton on purpose 

 to see the bee. 



" Taken freely breeding in snail-shells on the sand-hills at 

 Wallasey in 1855, Rev. H. H. Higgins; and similarly by 

 Mr. J. T. Carrington some years afterwards " (Willoughby 

 Gardner, " Hymenopt. Aculeat. of Lancashire and Cheshire/' 

 Liverpool, 1901, p. 50). 



" This species has been bred in numbers from old shells, 

 chiefly whelk, found on the Wallasey sand-hills by Mr. G. 

 Arnold. A. H. H." 



Also said by Smith to burrow in hard banks, and by Saunders 

 (" Hymenopt. Acul. Brit. Isles '*) in the ground. 



3. Osmia balearica, Schmdkt. (Palma, Majorca). Snail- 

 using instinct recorded by author. 



4. Osmia bicolor, Schrank. (Veyrier, near Geneva : May 15, 

 1909). The commonest British species with the instinct. 



F. Smith's record (1844) of this species is quoted under 

 aurulenla. He also states in " Zoologist," vol. ii, 1844, 

 p. 609, that he had seen bicolor " entering her burrow 

 formed in the perpendicular side of a sand-pit at Gravesend." 

 See also aurulenla. 



" 0. bicolor ' commonly burrows in banks ' (F. Smith), but 

 I have only found its nest in snail-shells, which he apparently 

 considered exceptional ! R. C. L. P." 



See also pp. xxviii, xxix for the shell-covering instinct of 

 this species. 



5. Osmia cyanoxantha, Per. (Corfu : June 1, 1901). " A 

 rarity. Instinct on authority of Fabre. F. D. M." 



6. Osmia exenterata, Per. " A Protosmia and the link be- 

 tween Osmia proper and Heriades. F. D. M." Ferton (1894) 

 received from Bizerta a shell of Bulimus [Stenogyra] decol- 

 lates, containing 2 $$ and 3 SS of this species. 



7. Osmia ferruginea, Latr. (Algiers : Apr. 20-28, 1898). 

 " This species is identical with igneopurpurea of Costa. S. 

 Europe and Algeria (not rare). F. D. M." 



The associated snail-shell collected with the bees by the 

 Rev. F. D. Morice was identified by Mrs. G. B. Longstaff and 

 Mr. G. C. Robson as Helicella (Helix) virgata, Da Costa, var. 

 alba, Taylor. The shell was unfortunately imperfect.
