STEROPES PANISOUS. 131 



some accidental deaths having occurred, I put out the 

 remaining six or seven on a growing tuft of the grass, 

 and presently watched one creep up to near the top of 

 a leaf and make cross ties of silk, which drew that 

 part of the leaf together in a somewhat tubular form, 

 an occupation which lasted four hours, before the little 

 creature retired within to rest from its labour. The 

 next morning I could see where it had eaten a piece 

 out from the edge of the leaf half an inch below its 

 residence, and could then detect the similar abodes of 

 five others. By the next evening the tip of the leaf 

 had become very much more attenuated, and formed 

 quite a cylindrical long point as far down as the notch 

 at the edge. 



By the 30th of June this individual had become 

 whitish-green on the body, with a decided bluish-green 

 soft dorsal line, faintly bordered with a paler whitish 

 stripe ; a whitish subdorsal line was also just visible ; 

 the head brilliantly black and shining, and also the 

 linear plate on the second segment. This segment 

 seemed not to have grown, and now appeared short. 



After some time their tubular residences became 

 more conspicuous, and the leaves on the top of which 

 they were formed became more ravaged below them, 

 and by the 20th of July most of them were bitten 

 through at the midrib and had fallen away empty, and 

 larger tubes were made on fresh leaves. On opening 

 one of these on the 3rd of August I found the larva 

 waiting to moult ; it was exactly 6 lines long, of a 

 delicate light, rather bluish, green, with a dorsal line of 

 slightly darker green, edged with a fine soft whitish 

 line ; a broad very pale bluish-green stripe of the back 

 follows, then a line of darker green like the dorsal line, 

 followed by a stoutish line of whitish ; the head black 

 and rough ; the linear transverse plate on the second 

 segment is interrupted on either side by the green 

 ground separating a small part of the black ; an 

 unbroken black rough plate is on the anal segment. 



On the 6th of August I took a larva from its tube,
