104 THE ENTOMOLOGIST. 



lathamianus ; Stephens, Cat. ii, p. 184, 7039, lathamiamis (1829) ;

" Ohs. — Variat colore obscure testaceo et brunnea." 



It will be observed that this form was named by Swederus 

 from a British specimen, or specimens, which at the time the 

 description was made were in the collection of Francillon. I 

 learn from the authorities of the Hope Museum at Oxford, in 

 which Francillon's Collection — the oldest British collection 

 extant — is at present, that there are now no specimens in the 

 collection answering to Swederus's description. 



This aberration is fairly common in most of the localities in 

 which S. revayana is found. I have a considerable series from 

 the New Forest.
