22 AGROTIS OBELISCA. 



blackish -green stripe mentioned above. Along the 

 middle of the side runs in an undulating manner 

 another pale greenish-grey line, somewhat interrupted 

 and irregular as to its thickness, and at some distance 

 below, immediately beneath the black spiracles, is a 

 broad stripe of dirty-whitish, having a fine line of 

 smoky blackish-green running through the middle of 

 it. Belly uniform pale smoky-green. Tubercles dark 

 smoky-green and shining, spiracles black. The ground 

 of the back is finely freckled with darker atoms. The 

 head is smoky brownish, freckled with darker, and its 

 lobes streaked with darker; the plate of second seg- 

 ment very shining dark smoky blackish-brown, the pale 

 dorsal and subdorsal lines distinct on it. Tubercular 

 warts shining. The segments rather deeply wrinkled. 



On the 16th of June, I was delighted to see the 

 wonderful change that had come over these larvaB; 

 both big and little were arrayed in attractive colours. 

 The ground colour of the back is now a flesh colour 

 or pinkish-ochreous, the dorsal line passing through 

 a pear-shape of pinkish-bronze or pinkish-grey, with 

 dark freckles, the small end of the pear behind ; the 

 sides dark pinkish-grey with opaque whitish ragged 

 lines below the spiracles, and the whole of the belly 

 and pro-legs opaque white, rather shining, and having 

 a lovely opalescent gleam of pinkish on this and all 

 over the body. 



By the 25th of June these colours began to dis- 

 appear, and to be replaced with others of a very dull 

 and plain character. (W. B., 1870, Note Book I, 3, 

 4, 16, 17.)

 feel greatly indebted, I have had the great satisfaction 

 of rearing and figuring larvae of this species. They
