GEOGRAPHICAL DISTRIBUTION. 
The var. trivialis Moq. and the loosely described sub-varieties fasciata of Gassies, 
Millet, and Baudon are common and widely distributed, as are the forms albidula 
Bourguignat, grisescens Colb., deleta Moq., obliterata Picard, and fasciata Dum. et 
Mort. in a much lesser degree. 
The sub-vars. coalita Pascal and leucozona Moquin-Tandon are local forms, but 
often plentiful where they are found. 
The sub-vars. monozona Moq. and bizonalis Pascal are by no means common 
forms, though on record for Eastbourne, Tenby, Cambridge, and other places in 
England and Wales as well as for France. 
The sub-vars. elegans and fasciata of Moquin-Tandon are really quite rare in 
this country, though the var. fasciata has been found at Newquay, Cornwall, by 
Mr. J. H. James ; at Gotherington, Gloucestershire, by the late Dr. J. W. Williams; 
Roundstone, Galway, Ireland, where it was found in Aug. 1889 by Mr. G. W. 
Mellors ; and also from Dublin, where it was obtained in April 1887, by Dr. Scharff; 
but in France both forms are recorded from the Ain and the environs of Lyons by 
Locard. The var. fasciata has also been found near Bordeaux by Dr. Scharff. 
The sub-var. Aypozona has been collected at Tenby, Pembrokeshire, in Oct. 
1890 by Miss F. M. Hele, and in 1895 by Mr. A. G. Stubbs. 
The sub-var. lentiginosa, Great Blasket Island, Kerry, June 1918! Mr. A. W. 
Stelfox ; there are also several other records of its occurrence in the British Isles 
in a more or less characteristic state, but truly distinctive specimens are far from 
frequent.
