Ferton (1894) has found a number of Helix ericetorum and 

 carthusiana containing each a single cell occupied by an adult 

 0. nifohirta. At Marseilles he saw a rufohirta roll a small 

 empty shell of a Helix sp. ( ? XeropJiila group) to a large tuft 

 ( kt toufie ") covered with dead leaves, etc., 2 - 20 metres off. 

 On the way it took half an hour's rest. Reaching the tuft, 

 it surmounted with difficulty all sorts of obstacles, stones, 

 sticks, leaves, etc., till it reached a suitable spot; then it 

 carefully turned the shell mouth downwards, and retired for 

 a rest before proceeding to clean and provision the shell. It 

 was hidden two centimetres deep under a pile of leaves, in 

 which was left an opening equal to about the diameter of the 

 shell, making communication between the hiding-place and the 

 world outside. On the other hand, Ferton records (1897) 

 that the species, which is common at Bonifacio, does not 

 generally behave like the individual observed above at 

 Marseilles, but as often rolls shells after provisioning them. 

 It utilises Cyclostoma elegans, also (at Poitiers) Helix 

 cyzicensis. 



14. Osmia spimdosa, Kirby (Swanage : July 20, 1900). 

 " H. M. Hallett has very lately recorded finding this sp. 

 in a snail-shell (I believe in Trans, of the Cardiff Ent. Soc). 

 F. D. M." 



15. Osmia {Protosmia) stelidoides, Per. " A Protosmia like 

 exenterata. F. D. M." 



Ferton (1908) states that this species nidificates in a Helix, 

 at Tebessa, Province of Constantine, Algeria. 



16. Osmia tricornis, Latr. (Nimes, S. France : May 6, 1910). 

 " Common in S. Europe. Instinct on the authority of Fabre. 

 F. D. M." 



17. Osmia versicolor, Latr. (Island of Zante : May 21, 1901). 

 ;c Viridana, Moraw. (cited by Fabre), is considered by Ducke 

 to be a var. of versicolor, but Ferton emphatically denies 

 this. F. D. M." 



Ferton (1901) states that this species utilises the big shells 

 of Bidimus [Stenogyra~\ decollatus. It does not roll these 

 about (being far too large), but is content to choose a shell 

 more or less hidden already, for example, in a crack or a 

 tuft of grass.
