86 LEPIDOPTERA.

posticum. 

 Whilst referring to what I have already said of this species 

 under perocliraria, I will try, on account of the great re- 

 semblance between the two species, to make the differences 

 between them even more distinct. I have already mentioned 

 the very different antennae of perochj^aTia as the most strik- 

 ing point of difference between the two species ; but there 

 are yet several differences, as will be seen from the following 

 description. 



Ochraria is rather larger than perochraria ; the apex of 

 the anterior wings is sharply pointed, and the hind margin in 

 the male very slightly rounded ; in the female it is straighter, 

 whence the apex is more pointed. Head, thorax and all the 

 wings are pale ochreous-yellow, sometimes with fine brown 

 atoms; the abdomen is rather paler. The female is usually 

 darker; but sometimes we find females as pale as an average 

 male and sometimes we find males as dark as an average 

 female. The anterior wings have, as in perochraria, three 

 generally dark brown (more rarely rather paler), distinct 

 transverse lines ; of these the first is curved, the second in the 

 middle, like a '* central shade," is almost straight, and the 

 third and darkest is finely toothed and slightly curved. 

 Between the first and second lines (thus not on the second 

 line as in perochraria) is a very faint ochreous-brown short 

 streak, often altogether wanting. The third line is externally 

 bordered with paler, and parallel to it, near the dark hind 

 margin, is a very pale indented line or rather a fascia of spots. 

 The cilia are hardly any darker than the disk of the wings ; 

 before them there is generally a fine dark-brown line, and not 

 rarely in the cilia themselves, at the end of each nervure,isa 

 small blackish spot.
