236 LEPIDOPTERA. 



Switzerland, the Tyrol, Cai'inthia, (lalicia, and Hun- 

 gary. 



(Mesogona acetosellae, Fah. This species bears a 

 curious superficial resemblance to Tamiocampa stcdilis, but 

 is much larger and its fore wings are about one-half broader. 

 Its head, thorax and fore wings are reddish-drab dusted 

 with grey or black ; first line very oblique, red-brown edged 

 inwardly with pale yellow ; second line very even and con- 

 spicuous, gently curved, similar except that the pale edging 

 is reversed ; beyond this a row of blackish dots indicates the 

 subterminal line ; upper stigmata both large, slenderly edged 

 with pale yellow and inside this with a dusting of black ; 

 hind wings broad, smoky reddish-white, with a dark border 

 behind, and the cilia dull red. 



A single specimen was captured at sugar at Arlington, 

 Sussex, by Mr. Thomas Salvage on October 26, 1895, and is 

 now in the collection of Mr. Robert Adkin. No doubt 

 ajjpears to rest upon this capture, yet to establish a species 

 as British upon the occurrence of a single specimen is always 

 unsafe, especially when, as at present, great numbers of larvas 

 and pupge imported from the continent of Europe are reared 

 — and possibly liberated— in this countiy. Should this 

 species have effected a migration and be able to maintain 

 itself we shall soon, no doubt, obtain further evidence. It 

 occurs in the South of France, Northern Italy, Dalmatia, 

 Switzerland, Germany, Hungary, and Southern Russia.)
