THE KANSAS PEACH. 75 



fested with the second brood of larvpe. Some of the peaches had been 

 bored into a little way near the stem by what was evidently, from the 

 size and nature of the burrow, nearly full-grown larva^ of the second 

 brood. One of these was found, and also one pupa. On further ex- 

 amination, however, it was found that the larvae of what is undoubt- 

 edly the third brood (the second of the summer broods) were present 

 in numbers, not in the fruit, but in the short stems of the fruit, which 

 at this season are green and somewhat succulent. In these stems 

 they had made their little chambers not unlike those in the twigs de- 

 scribed above, or those in the crotches in the fall, except that they 

 were for feeding purposes and not lined with silk, as are the latter. 

 Others were also found at the base of the leaf stalks, just as we had 

 been finding them in our breeding-cages. 



We were unable to carry our breeding-cage material farther than 

 this point at Washington, D. C, and Mr. Ehrhorn was unable to fur- 

 nish additional supplies, but he writes that he found minute larvse in 

 the crotches of the trees as early as August 21. It would seem from 

 this last and very important observation that some, at least, of the 

 fourth brood of larvjv, if not all of them, go into winter quarters, and 

 at a period much earlier than would have been supposed. These facts 

 go a long w^ay toward clearing up the life- history of this insect, and 

 indicate a much more uniform habit in the different broods than has 

 been hitherto supposed. The old idea that this insect is double 

 brooded, the first brood living in the wings of the second brood, af- 

 fecting the ripening fruit, must be abandoned. At the time of the 

 appearance of the first brood of moths, during the month of May, the 

 fruit of the peach is of considerable size, especially by the end of the 

 month, but is green, hard, and densely hairy, and is probably rarely 

 if ever chosen by the parent moths as a nidus [repository] for their 

 eggs. 



The normal location of the eggs, and the point at which larval de- 

 velopment begins, is indicated by the foregoing notes, and there is no 

 reason to doubt but that at all seasons of the year larvae develop in the 

 new^ growth, entering normally at the axils of the leaves or in the 

 stems of the green fruit. In these situations the eggs are placed, and 

 the young larva? construct their little oval chambers, which they 

 abandon from time to time to make new ones, rarely doing enough 

 damage in the later broods at any one point to be noticeable. As 

 they attain larger size they travel more, and often bore into the fruit near 

 the stem, where the greater exudation of gum and more serious char- 

 acter of the injury draw attention to them. In the case of the bur- 

 rows in the twigs, the more abundant new growth and more mature 

 condition of the wood render the injury much less noticeable, nor are
