leaf ; I looked for them early in November, and saw the pieces of leaf 

 were nearly rotten and deserted by the larvje, they having entirely 

 gone from view. 



On 17th of February, 1883, while noticing the few large leaves 

 on the plant which I kept in a window, I chanced to observe two 

 small watch-pocket-like apertures cut in the upper epidermis of one 

 of them, and two minute black atoms of frass lying near, and in course 

 of a week these hopeful appearances were seen on more of the leaves, 

 and began to increase in number, but all of them were very small, and 

 it was not before the morning of the 25th that I was gratified with 

 the welcome sight of one of the larvae, the only one it seemed that had 

 survived the winter thus far ; it was on the upper surface of a leaf 

 creeping deliberately along the midrib towards the footstalk ; in the 

 afternoon I could see it attached to the under-side of a neighbouring 

 leaf ; next morning after vainly looking over the plant, I found it had 

 crawled off and was lodged on the rim of the flower-pot, a circumstance 

 that led me to reflect on the roving disposition it had so soon betrayed, 

 there being evidence that it had wandered all over the plant ; so now, 

 in fear of losing it, I again took it into the captivity of a bos, where for 

 a day or two it mined into a gathered leaf and ate out the parenchj'^ma 

 from a largish area just as it had done in autumn ; then I gave it 

 more light and air, but by 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 mouth 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 

 fi'esh leaf, but without feeding, and again afterwards it moved to one 

 or two other fresh leaves, and even made a small puncture in them, 

 but it did not feed ; on 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 H. 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 succeeded in finding a larva of 

 glohularus 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 Centaitrea 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 b.eginning to feed ; 

 for two days it ate sparingly, but thenceforward more freelv. making
