THE IjARVM 



OF THE 



BRITISH MOTHS. 



HYPENA ftOSTRALIS. 



My first acquaintance with the larva of Hypena 

 rostralis was made at Deal at the end of August, 1888, 

 when I found a full-fed specimen wandering about 

 near some hop plants in a garden, and evidently 

 searching for a suitable place in which to spin up. I 

 placed it in a cage in which were other species, and 

 saw no more of it until the imago appeared in the 

 month following. On the 24th of June last I next 

 saw larvae through the kindness of Mr. W. R. Jeffrey, 

 of Ashford, who sent me two from a few he had 

 reared from eggs deposited by a captured female. 

 The ? moth, as is well known, hibernates, and 

 deposits her eggs in spring or early summer; but 

 whether the S also hibernates, and pairing is effected 

 in the spring, or this takes place in the autumn, I 

 cannot say. Mr. Jeffrey tells me the eggs from his 

 moth were deposited about the 15th of May, and 

 hatched on the 26th of the same month ; the larger 

 of the larvae received was nearly full-grown, so next 

 day I described it as follows : 



About an inch in length, and slender proportionately;
