4 PROORIS GLOBULARLE. 



parenchyma from a largish area just as it had done in 

 the autumn ; then I gave it more light and air, but by 

 the 6th of March it had made only five mines, each 

 no bigger than itself, of irregular oval shape, and all 

 through the remainder of this month of cold north- 

 east wind it did not feed, but laid up as though asleep, 

 until the 1st of April, when it removed to a fresh leaf, 

 but without feeding ; afterwards it again moved to one 

 or two other fresh leaves, and even made a small 

 puncture in them, but it did not feed. On the 5th of 

 April it seemed unable to keep on its feet, appeared 

 in a moribund state, and was dead by next morning. 



I lost no time in communicating this mishap, and 

 sending a pencil sketch of the defunct to Herr EL 

 Disque, who with most obliging good nature, which 

 I am so glad now to acknowledge thankfully, at some 

 sacrifice of time, sought out the distant spot where he 

 had captured the insect last year, and actually suc- 

 ceeded in finding a larva of globularice no bigger than 

 the little one so recently lost, an instance of keen sight 

 faculty, which astonished as much as it delighted me 

 when I received the larva on the 2nd of May, while 

 it was yet fixed on a leaf of Gentaurea waiting the 

 next moult. This was accomplished on the 9th, 

 seemingly an exhausting process, as the larva remained 

 quietly resting for two days and a half before beginning 

 to feed; for two days it ate sparingly, but thenceforward 

 more freely, making larger blotches, until the 22nd, 

 when it left its food to seek a suitable place in which 

 to lie up, and after being at a corner of the box for 

 some hours it eventually moved off to another part 

 under the lid, where, on the 24th, it spun a foot-mat 

 of silk threads, and became fixed in them feet upper- 

 most, until the moult took place on the 30th; and 

 finally it became full-fed on the 11th of June, and 

 later entered the earth. 



In addition, Herr H. Disque most kindly sent me on 

 the 6th of May, four fine larvae, at that time a moult 

 in advance of the foregoing, and their last moult
