198 LBPIDOPTERA OF THE ISLE OF PURBECK. 



the present time, only 2,102 different kinds of butterflies and 

 moths are known to exist in the British Isles, the peculiar richness 

 of the insect fauna of Purbeck will be the more readily appreciated ; 

 and we much doubt whether any similar district of such very 

 limited area can boast of such an extensive list. 



It should here be stated that both in the former List, as well as 

 in the present Supplement, the Kev. C. R. Digby and myself are 

 entirely responsible for all the records given ; for, unless otherwise 

 stated, the various captures have, in almost every instance, been 

 made by ourselves. This statement was not made in the original 

 preface because we assumed that it would be taken for granted ; 

 but such has not always been the case (vide " Entomologist," xix., 

 p. 95). 



N.B. Species marked thus * have not previously been recorded 

 from the county of Dorset.
