slightly elongate, tumid above, terminal slender acute, rather depending : 

 maxilla short. Antennae simple in both sexes, slightly pubescent within in 

 the males : head rather broad : eijes large : thorax rather stout, with a bifid 

 crest behind : wings slightly deflexed during repose ; anterior somewhat 

 rounded on the hinder margin, the disc variegated, and adorned with 

 irregular oblique fasciae and clouds; sometimes abbreviated; posterior 

 ovate-triangular : hodii rather slender, with a short tuft at the apex in the 

 males, rather stouter and acute in the females, with a short l)ifid tuft: legs 

 short, posterior longest. 



The insects of this genus resemble the two preceding by having 

 the anterior wings marked with obhque bands or lines, but from 

 those they may be known by having the thorax crested behind, the 

 crest long and bifid, whence the name I have applied to them : the 

 genus is decidedly not synonymous with Thiratcs of Treitschke, as 

 given by iVIr. Curtis, the type of that genus being Padisca profun- 

 dana. 



A. Anterior wings dark, with continuous oblique fasciae in the middle. 



a. Anterior wnngs with obscure fascim, the costa with a pale spot at the apex, with 

 metallic streaks : — Astatia, Hiihner.

 No. 6882. 



Anterior wings oblong narrow, obtuse, of a smoky-testaceous hue, with an 

 obscure oblique brownish streak or spot at the base towards the irmer 

 margin ; a waved broader streak, of similar colour, arising from a palish 

 blotch on the costa, and reaching to the anal angle ; beyond which on the 

 costa is a short ustulated brown one, widest on the costa and narrowing 

 towards the hinder margin, which is faintly variegated with some palish 

 lines : posterior wings dusky or black. 



The male is smaller, of a deeper hue, sometimes blackish-brown, with very 

 dark, nearly black, markings. 



Extremely variable in size, and in the strength and intensity of its colours and 

 markings. 



A very common insect throughout the metropolitan district ; taken 

 also not uncommonly in other parts of the country ; I have caught 

 it near Dover, Brighton, Ramsgate, Cambridge, lMonk''s-wood, &c.: 

 it likewise occurs in Devonshire and the New Forest.
