96 BANKIA BANKTANA. 



the small undeveloped pair of legs on the eighth seg- 

 ment were still to be noticed ; the slender proportions 

 of the larvae, remarkable from the first, seemed now to 

 be even more striking as they attained full growth 

 towards the end of the month, when they measured 

 from eleven to twelve lines in length ; they were of a 

 very yellow-green colour, with yellow segmental folds, 

 the round head of a light green colour with upper lip 

 whitish, and mouth black; the dorsal line dark green, 

 though faint; the subdorsal stripe primrose-yellow; 

 the roundish spiracles flesh-coloured, placed on the 

 deep yellow thread-like trachea, showing faintly 

 through the skin. 



On the 1st of August one larva began to spin its 

 cocoon just beneath the crown of the grass-roots, 

 almost close to the surface of the earth ; and others 

 followed in the same way during the next four days, 

 though one larva lingered two or three days longer ; 

 this was exactly an inch long as it lay stretched out, 

 according to the habit of this species when at rest 

 among the grass, which it matched in colour remark- 

 ably well. 



The pupa is very short, stout, and dumpy, three 

 and a half lines in length, the thorax and wing-covers 

 well defined, the last rather long in proportion, 

 and from them the abdomen tapers obtusely to the 

 tip, which is furnished with two fine points and 

 minute curly-topped bristles ; its colour at first is of a 

 light drab, but towards May of the year following it 

 becomes a dark brownish-green, and is rather shining.

I am indebted to Mr. Carrington for eggs of this 

 species. They were laid on June 23rd and 24th, 1868, 

 and received by me on the 28th June.
