32 LEPIDOPTERA. 



transverse dusky striga? slightly indented, one before, the 

 other beyond the middle, and a dark wavy fascia towards 

 the hinder margin ; the latter fascia is the only one dis- 

 tinctly represented on the posterior wings; cilia ochreous, 

 with a row of dark fuscous spots. 



The specimen described was taken by Mr. Hunter, in 

 London, and I am informed that Mr. Bond and Mr. A. F. 

 Sheppard have also specimens of this species. 



Duponchel states, that the species occurs in June, among 

 oaks. 



Botys decrepitalis, Fischer v. R. (H. S., IV., 40, 

 Pyral. pi. x., fig. 67,68.) 



Not closely allied to any of our known species; perhaps 

 most like a faded, indistinctly marked Etialu, but not so 

 white as that insect. 



Expands 11 lines. Anterior wings pale greyish- white, 

 with a faint indication of the hinder striga, which is not in- 

 dented towards the base after leaving the costa; the central 

 dark spots are very indistinct ; along the tip of the costa 

 and hinder margin are several distinct dark brown spots. 

 Posterior wings whitish, with a central dark spot, a slender 

 hinder striga and a pale fuscous cloud immediately before 

 the hind margin, on which latter are several dark brown 

 spots. 



Described from a female specimen taken by Mr, Hodg- 

 kinson. 



Mr. Buxton took a male insect (expanding 12 lines), which 

 may, perhaps, be referable to this species, but the ground 

 colour is darker, and all the markings indistinct, even the 

 marginal dark spots are hardly developed. 



On the continent this occurs in the Alps, from June to 

 August.
