teeth being 12 in number, the 7. segment compressed in the 
middle and forming a prominent triangulär spine. (B. M.) 
The specimen in the British Museum is the only one J 
have seen, but Dours includes the species in his »Catalogue 
des Hymenopteres de France«. The British specimen is from 
Leach’s collection and has a numbered ticket attached. On 
reference to his private manuscript catalogue the entry is foun- 
ded: »June, found settling on a footpath our house« at Spitch- 
wick, Devonshire.« England.

Utriusque sexus jam edidi descriptionem, nunc mutato 
nomine iconem praebeo. Megachile punctatissima Latr. prorsus 
distincta et in Liguria nondum inventa, si congener, saltem ad 
alteram Heriadum divisionem amandandam. Heriades pusilla 
nostras, meo judicio, nusquam in lucem tradita, nidum habitat 
cylindricum, simplicem et in medulla Rubi profunde atque tor- 
tuose fossum. Nidus casulis parvis decem vel duodecim constat.
