larger blotches, until the 22nd, when it left its food to seek a suitable 

 place to lie up in, 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 21th, it spun a foot-mat of silk threads, and became fixed in them, 

 feet uppermost, until the moult took place on the 30th ; and finally it 

 became full-fed on 11th of June, and later entered the earth. 



In addition, Herr H. Disque most kindly sent me on 6th of May, 

 four fine larvae, at that time a moult in advance of the foregoing, and 

 their last moult occurred on the 18th, 19th, and 20th of the month ; 

 they all fed remarkably well, making very large and conspicuous blisters 

 or mines in the leaves, from which they devoured the parenchyma to a 

 great extent, even sometimes abstracting nearly the whole from a leaf; 

 towards the last they were somewhat careless in not extruding all their 

 frass, which could be seen in a long trail within some of the clear 

 blisters, and they often remained within them at night and for many 

 hours at a time, apparently asleep, when their form could be readily seen 

 through the transparent cuticle. In this way they attacked quantities 

 of leaves, but just at the last, and in one instance only, a larva ate a 

 large hole quite through the entire substance of a leaf. 



It may be imagined with what admiration I so often about this 

 period perused the graphic account of the discovery of the adult 

 larva, and its interesting habit, by the late most eminent Entomologist, 

 Professor Zeller, in the "Entomologist's Annual" for mdccclxiv, pp. 

 103-7 (originally published more than thirty years ago), and of the 

 great pleasure it was then giving me to be, as it seemed, verifying its 

 perfect accuracy, and not without indulging the hope of future com- 

 munication with him. Alas ! too late ! 



Their full growth was attained from May 30th to 2nd of June, 

 and then each in turn lingered two, three, or four days on the surface 

 before entering the earth. 



Erom three of the pupsD the perfect insects, two males and a 

 female, were bred on 9th of July, having been j)receded a few days by 

 an Ichneumon from the fourth, which I have since learned from a friend 

 has been pronounced by Mr. Bridgman to be an undescribed species 

 of Anomalon. 



The egg of glohuJarice is of a long-oval shape, about -^~' loiig and 

 yV wide, having at first a depression on some part of the surface, and 

 adhering lengthway to the substance whereon laid, singly, or sometimes 

 two or three together ; the shell is very finely ribbed, and of a deep 

 vellow colour, which changes a few hours before hatching to a dull
