NEW BRITISH SPECIES. 87 



The posterior wings have, as in perochraria, two trans- 

 verse lines, but the distinct dark brown central spot is placed 

 before the first transverse line (not behind it, as in peroch- 

 raria) ; the second and darkest transverse line consists of 

 several small curves ; its bordering and the hind margin are 

 as those of the anterior wings. 



Beneath all the wings have the colouring of the upper 

 side, but generally much suffused with black-brown atoms, 

 especially the anterior wings. They have, as in perochraria, 

 two black-brown transverse lines, and near the hind margin 

 is the pale indented line or fascia of spofs more distinct than 

 on the upper side. On each wing, before the first transverse 

 line, is a black-brown spot, but not unfrequently this is 

 wanting on the anterior wings, or even on all. The cilia are 

 rather darker than above, with the tips paler. 



Ockraria, of which the females are more rarely taken, 

 flies in July and to the end of August in dry meadows and 

 on the borders of woods near Vienna, in Hungary, Carinlhia, 

 near Augsburg, Glogau, Frankfort-on-the-Oder. It is curious 

 that ochraria has not yet been found in Bohemia, Saxony 

 and Mecklenburg, and there perochraria alone occurs, whilst 

 at Laybach, Frankfort-on-the-Oder and Glogau, where ini- 

 faria however is wanting, both pi^'^ocliraria and ochraria 

 occur, the latter being rather the scarcer, and near Vienna 

 all the three species occur in equal plenty. 



Herr Friedrich Schlaeger in the Bericht des 



LEPIDOPTEROLOGISCHEN TaUSCHVEREINES, 1846, p. 171, 



writes tlnis : — 



" Fischer von Roslerstamm has already called our atten- 

 tion to the fact that under the name of Acidalia ochrearia 

 two different species have been confounded. The larger
