12 AGROTIS CORTICEA. 



with a fine thread of paler along its lower edge, 

 followed at a little distance by another such pale and 

 rather thicker line, though much interrupted or broken 

 by the deep wrinkles of the skin ; at some distance 

 below this runs the subspiracular stripe of the same 

 paler greyish-brown, with a streak of the ground 

 colour through the middle of it. The head has the 

 front margins of the lobes broadly streaked with 

 blackish, and a little at the sides also, and the mouth 

 is large and sometimes blackish ; the plate on the 

 second segment is not so noticeable as usual in this 

 genus by any difference in colour, though it is a little 

 darker brown towards the margin in front ; the dorsal 

 and subdorsal paler threads are faintly seen to pass 

 through it. 



As the larva approaches full-growth the skin becomes 

 somewhat shining, and the warts which immediately 

 after the last moult came out black, grow paler in the 

 centre, and are of a dark brown all round it, each still 

 furnished with a short, fine bristle ; the black spiracles 

 are rather small in size. 



As noticed before, the general appearance is more 

 unicolorous than that of any species of Agrotis I have 

 yet seen. 



The pupa is of the ordinary Agrotis form, rather 

 stout, and very smooth ; at first whitish, and changing 

 by degrees to a light orange-brown. (W. B., July, 

 1871 ; E.M.M., VIII, 89, September, 1871.) 



Agrotis cinerea. 

 Plate LXXI, fig. 5. 



On the 6th of June, 1882, I received from Mr. 

 W. H. Ballett Fletcher, then at Oaklands, Hailsham, 

 Sussex, sixteen eggs of this species, part of a batch 

 laid by a captured moth. 



The egg is globular or hemispherical, and ribbed
