life-history, with a descriptiou of the larva, iu the Scientific American 

 for June 16, 1887, and iu the Gardener^s Montlily for July 19, 1887 (vol. 

 29, p. 216), under the name of G. punctipennis^ which is a sfnonym of 

 foliacea. 



I placed my beetles on fresh apple leaves and awaited developments. 



More than a month elapsed before I found any eggs in the jar. On 

 the 9th of July I found several clusters attached to the stems and bases 

 of the midribs of the leaves. They are generally in twos and threes, 

 ranged side by side. They are about one millimeter in length, slender, 

 oblong rather than oval, of a pale, dull orange color, somewhat trans- 

 lucent, and Professor Popenoe, who has also obtained them, says that 

 ^' under a high magnifying power the shells are seen to be minutely 

 granulated." 



By the 17th of July a number of larvae had hatched. They are nearly 

 cylindrical, of a dull black color, and r ather more elongate in proportion 

 to their diameter than the larvcB of G. cludyhecK When grown they feed 

 on the parenchyma of the leaf, indifferently on either surface, but later 

 they gnaw holes in it similar to those made by the perfect insects. The 

 tirst molt took place in eight days, and two or three of the small larvae 

 perished in the process, being unable to entirely withdraw themselves 

 from the outgrown skins. The second molt occurred one week later, and 

 in this also one larva perished. During these periods there are no changes 

 of color or maculation. August 2 one larva had completed its growth, 

 and as it was making its way into the earth I put a stop to its further de- 

 velopmenc by transferring it to the alcohol bottle. The following char- 

 acters were noticed: Length of mature larva from 6 to 7 millimeters; 

 diameter, 1| millimeters; form, cylindrical, tapering somewhat poste- 

 xiorly; general color varying from dull black to dark fuscous; i^iliferous 

 plates inconspicuous, of the same shape, number, and arrangement as 

 those of G. chalyhea, black in color and slightly polished, each giving 

 rise to from one to three minute hairs; head rounded, cordate, deep 

 black, but not brilliantly polished; prolegs well developed, faintly an- 

 nulate at the joints with dingy white. 



The larvae move about considerpjbly, but in a slow and rather clumsy 

 fashion, with the tip of the abdomen appressed to the surface of the leaf 

 or stem to assist in keeping them in position. 



The pupa is inclosed in a frail earthen cocoon or cell, just beneath the 

 surface of the ground. 



!N^one of the beetles from this brood have emerged, and it is possible 

 that they may hibernate. Several of the parent beetles were, August 

 14, still alive and as voracious as ever, while eggs and young larvae 

 were still to be found on the leaA^es. 



August 14 two larvae entered ground and the beetles emerged on 

 the 28th of the same month — the duration of the pupal stage of life, 

 being less than two weeks.
