74 THE KANSAS PEACH. 



found that many eggs had been deposited on these peach twigs, an 

 egg having been placed apparently just above the base of the petiole 

 of nearly every leaf. When examined, most of the eggs had hatched 

 and the larv?e had entered the twigs at or near the crotch formed by 

 the leaf and twig, the point of entrance being indicated by a little 

 mass of brown excrement. The egg had evidently been placed in the 

 protection formed by the two little spurs at the base of the petiole. 



In one instance nine eggs were deposited around the base of a sin- 

 gle leaf, six of tli'-m close together under one of the bracts at the base 

 of the petiole, and three in the depression or scar left by the second 

 bract, which had dropped. 



The recently deposited eggs are white in color and iridescent, but 

 before hatching become distinctly orange. They measure about four- 

 tonths of a millimeter in length by two tenths of a millimeter in breadth, 

 are somewhat ovoid, and are lightly attached lengthwise to the twig by 

 a glue-like material. Under a high power they are seen "to be coarsely 

 and rather regularly reticulated, as shown in the illustration. Fig. 16, «. 



In confinement the moths live about ten days, and most of the egg 

 laying is in the first half of this period. The habits above described 

 are those of caged moths, but it is reasonable to suiopose that in a 

 .state of nature the eggs are deposited in much the same way, and this 

 is rendered almost certain by the great regularity noted in the man- 

 ner of their dej)osition. In but one or two instances were the eggs 

 placed in other situations — one being placed on the upper surface of 

 a leaf close to the midrib, and two together j)laced in a groove at the 

 side of the base of the leaf. From eggs deposited later than those 

 first mentioned, viz., about June 3, larvae appeared June 15, indicat- 

 ing a period of about twelve days between the laying of the egg and 

 the hatching. 



The newly hatched eggs measure about one millimeter in length and 

 are of a very pale yellow color, with the head and the cervical and 

 anal plates black and the thoracic legs dusky. When first noted they 

 had excavated channels somewhat longer than themselves and about 

 twice as broad in the twigs, the entrance being marked by a small 

 mass of excrement. By June 3 most of the older larvae had abandoned 

 their original burrows and were constructing new ones in similar situ- 

 ations on fresh branches of the peach, with which they were from time 

 to time supplied. They continued to construct new burrows every 

 few days until they were full grown. On June 23, of the few remain- 

 ing individuals of this lot of larvae, one had already pupated in a folded 

 leaf and the other two were fully grown and about ready to transform, 

 which they both did before the end of the month. About the end of 

 June some peaches were received from Mr. Ehrhorn, said to be in-
