The Osmiae 



has a weakness for the Brown Snail and the 

 Garden Snail, in whose shells I find her taking 

 refuge in April when the north-wind blows. 

 I am not yet much acquainted with her work, 

 which should resemble that of the Golden 

 Osmia. 



The Green Osmia (0. vir'idana, MoRA- 

 VVITZ) takes up her quarters, tiny creature 

 that she is, in the spiral staircase of BuUmiiliis 

 radiatus. It is a very elegant, but very small 

 lodging, to say nothing of the fact that a con- 

 siderable portion is taken up with the green- 

 putty plug. There is just room for two. 



The Andrenoid Osmia (O. andrenoides, 

 Latr.), who is so curious with her naked red 

 abdomen, appears to build her nest in the 

 shell of the Common Snail, where I discover 

 her refuged. 



The Variegated Osmia (O. versicolor, 

 Latr.) settles in the Garden Snail's shell, 

 almost right at the bottom of the spiral. 



The Blue Osmia (O. cyanea, KiRB.) seems 

 to me to accept many different quarters. I 

 have extracted her from old nests of the 

 Mason-bee of the Pebbles, from the galleries 

 dug in a roadside bank by the Colletes^ and 



'A short-tongued Burrowing-bee known also as the Mc- 

 litta. — Translator's Note, gj
