STIGMONOTID^— ASTHENIA. 175 



This very pretty little species was reared from the above- 

 mentioned food-plant in the year 1880 by the late Mr. J. B. 

 Hodgkinson, in Lancashire, and other specimens have been 

 reared in subsequent years in the same manner, but I cannot 

 find that the habits of the moth have been noticed, or even 

 that it has been there taken in the imago state. The only 

 such capture with which I am acquainted is that by Mr. A. H. 

 Hamm in an oak wood with varied undergrowth, near 

 Basingstoke, Hants, and lour knowledge of the distribution 

 of this species is limited to these two counties, though it 

 seems almost certain that it will yet be found in some of the 

 many localities in which the Dyer's green-weed flourishes. 

 Abroad it is known to occur through the greater part of 

 Central Europe, and in Piedmont, Livonia, and Servia,
