PAMPHILA LINEA. 



Plate XVII, fig. 3. 



Of this long wished for larva I had the great pleasure 

 to receive six fine examples on the 11th June, 1882, 

 from Mr. W. H. B. Fletcher, who, most kindly mind- 

 ful of my desiderata, when finding himself at their 

 locality in the eastern division of Sussex, on the even- 

 ing of the 9th, succeeded in sweeping them from 

 Holcas lanatus, a very soft pubescent grass, with which 

 they assimilated both in colour and texture most 

 remarkably well. 



They had evidently done moulting, and continued 

 feeding well on the above-mentioned grass from seven 

 to fourteen days, and seemed rather to prefer it to 

 Brachypodium sylvaticum, another soft-haired grass, 

 which they also ate freely enough for a time ; the 

 experiments of trying them with this latter grass 

 suggested itself to me from the circumstance of my 

 having, a few years ago, gathered some of it, quite by 

 chance, which contained a spun-up pupa, that shortly 

 afterwards produced this butterfly. 



Their movements were very sluggish, and after eat- 

 ing a considerable quantity of food, they very slowly 

 began one after another to enclose themselves within 

 two, or sometimes three leaves of the grass, joined 

 together longitudinally by lacing or spinning, with 

 white silk, the edges more or less close to each other, 

 and became completely hidden ; the earliest spun itself 

 up on the 18th of the month, another on the 20th, and 

 the others during the next three days. 



The perfect insects, full-sized specimens, were bred 

 on the 15th and 16th of July following. 



The full-grown larva is 10 lines in length, its 

 general figure of moderate substance, stoutest in the 

 middle of the body, tapering a little from the thoracic 

 segments towards the head, which is globular and 

 projecting, larger than the second segment, which is
