 a little sinuous; apex mnrh i-onnded ; outer edge very oblique and eouvex, - 

 uuieh more so than usnal. Hind wings unusually long; the apex eontinuously 

 rounded, with a very fulh rouniled, outer edge. Venation somewhat as in 

 Eiiiafurmi, l)ut the sulicostal areole is much sliorteraiul l)roa(h_'r, and the first 

 two sui)eostal venules are shorter, less ol)li(iuely directed to the costal edge. 

 The arrangement of the discal venules much as in Eiiidti/riid. Hind legs 

 with the 1il)i;e considerably swollen, and the tarsi nearly as long as the tibiae 

 Coloration pale-brown above, with the under si(h' ol' the hind wings beauli- 

 fuUv checked and marliled with silvery-white and greenish-ochreous. 



This and the I'^uropean /'. /asc/a/aria Hiii)u. diller ti-om Fidonia in the 

 longer, more rounded fore wings, the apex being a little upturned, in the long 

 and much rouiuled hind wings, and singular mode of coloration. The singular 

 median crest on the head of our F. Jiinetarta is wanting in its closely-allied 

 European species fasciolaria, and there is nothing like it in any other species 

 of Fidonia and allies known to me. I restrict Hiibuer's name Perconia to 

 this and its European AXy, fasciolaria ; Hiibner's Fercoiiia is equivalent to 

 Treitschke's Fidonia, and has been hithertcj strangely ignored. The female 

 diifers from the male in the hind wings Ijeiug a little moic produced. The 

 larva of neither,/^'.sr/rt/(/r/r/ (ri'hraria) nn\- Jiuirfai-ia is known.
