344 THE MOTHS OF THE BRITISH ISLES. 



along the sides ; head and plate on first ring of the body black, 

 the latter edged in front with yellowish. It feeds on rock rose 

 {Helianthemum chamcEcistiis). At first it attacks the leaf from 

 the upper side, and partly burrows therein ; when older it clears 

 away patches from the under surface, leaving the upper skin of 

 the leaf more or less transparent ; as it approaches full growth 

 it likes to take its meals in the sunshine, and then eats the 

 top skin as well as other parts of the leaf, and also tender 

 shoots : July to May. The moth is out in June and July, as a 

 rule, but is sometimes observed in May. Its haunts are on 

 warm slopes of chalk downs and limestone hills, where it flies 

 in the sunshine. 



This species was first noted as British in March, i860, when 

 specimens from Worcestershire were recorded as Procris tenin- 

 cornis. It seems, however, to have been considered doubtfully 

 distinct from statices until 1863, when the caterpillar was found, 

 and the occurrence of the species in several other English 

 counties recorded. At the present time /. geryori is known to 

 inhabit Sussex (Brighton and Lewes districts), Kent (Canterbury 

 and Shorncliffe), Bucks (Aylesbury and Tring), Oxfordshire 

 (Chinor), Gloucestershire (Cotswolds), Worcestershire (Malvern 

 Hills), Derbyshire and North Staffordshire (Bakewell and 

 Dovedale), Yorkshire (Richmond, Barnsley, Sheffield, etc.), and 

 Durham (banks on the coast). In Wales, it is sometimes 

 common on Great Orme's Head, Carnarvonshire. 



COCHLIDID^. 



This family of moths mainly comprises tropical species, and 

 is but poorly represented in the Palasarctic Region. Only two 

 species are European, and both occur in Britain.
