 An immature example was found and sent to me by 

 Dr. Haines from Ringstead in April, 1913. Although 

 immature, I have no doubt about the identity of this 

 specimen. The only British record hitherto is that given 

 in Spid. Dors., p. 8 ; though there the locality was 

 given erroneously. The place of capture was, in fact, 

 under a stone or piece of rock in the island of Portland.
