154 FORTY-TMIBD REPORT ON THE StATE MuSEUM. [58] 



Specimen No. 2, I think, is the larva of the codling-moth, as I find 

 them on different parts of the tree, under the rough bark. Am I 

 mistaken ? There are some flat-headed borers at work on my trees, 

 but they seem to be confined to the ends of the small limbs nearest 

 the ground. The ends of the limbs are invariably dead, and the 

 borer is generally found in the dead wood. I have never found the 

 young borer in the green wood. Does the borer kill the end of 

 the limb, or does it only occur here because the wood is 

 rotten, or the bark easy to get under? I am cutting off all these dead 

 tips, and hauling them out to be burned. In the spring I intend to 

 wash the trunks of the trees and the large limbs with the carbolic 

 acid wash recommended by Mr. M. B. Bateham, page 535, in the 

 volume of the Country Gentleman for 1876 [also in 2d Report on the 

 Insects of New York, 1885, p. 25]. Am I doing the right thing? 

 With 2,000 trees to care for, 3'ou will see that it will be no small job.

The larvae found under the bark are footless maggot-like worms, 

 about three-eighths of an inch long by one-eighth broad, quite 

 pointed in front when the very small head and extensile anterior 

 segments are extended; rounded behind, with a short cylindrical 

 terminal projection. The two larva? sent are apparently of the same 

 species, but in different stages of growth — one having two lateral 

 rows of short spines, and the other being destitute of them. They 

 are probabl}^ larvae of some species of fly, of which, in this stage, I 

 have no knowledge. From the known habits of the larvae of the 

 Diptera, it does not seem at all probable that these could have occa- 

 sioned the separation of the bark. After the injury had occurred, the 

 eggs may have been deposited where the proper conditions were 

 found for the sustenance and development of the young larvae. If 

 additional examples of these forms — the more advanced ones — can 

 be sent in a living state, the perfect insect can perhaps be bred from 

 them. Their occurrence in large numbers under the above conditions 

 is of considerable interest. 



Specimen No. 2, is, as supposed, the larva of the codling-moth, 

 GarpocajDsa pomonella. 



The occurrence of the flat-headed borer {Ghrysohothrisfemorata) in 

 the ends of the small limbs of apple-trees is quite new to me, for I 

 can find no mention of it in the writings of any of our economic 

 entomologists. Its habitat has heretofore been given as in the trunks 

 and larger limbs of apple-trees. It is not at all improbable that this 

 form is a distinct species from G. femorata, and with different habits. 

 And, indeed, the large numbers of very different trees upon which G. 

 femorata is stated to occur, leads us to believe that we are confound-
