THE APPLE MIDGE AND THE APPLE-TWIG BORER. 1 25 



another generation. The puparia are to be found in the bottom of 

 apple barrels in cellars, and the flies appear in the spring. The species 

 does not appear to be known to entomologists, and it has therefore 

 been given in the recently published volume of Mr. Saunders on Insects 



Injurious to Fruits as Drosophila 9 In Packard's Guide to the 



Study of Insects, it is referred to (p. 414) as the Apple-Fly. It was 

 also noticed in my First Report on the Insects of New York (p. 219), 

 together with the larvae believed to produce the fly. 



The other species is the Mulohrus mali as named and described by 

 Dr. Fitch in his Second Report on tlie Insects of Xeio York (Reports I 

 and II, 1856, pp. 252-254), but now known as Sciari mali. It belongs 

 to the Mi/cetophiUdce which has place next, and is closely allied to, the 

 Cecidomyidce containing the wheat and clover midges and the Hessian 

 Fly. This species has been given the name of the apple midge. Its 

 larvae and pup^ need not be mistaken for either of the two preceding 

 species, the larva being long, slender, shining, glossy-white, without feet 

 or tubercles (family features, the specific ones, it is believed, have not 

 been recorded); while the pupa is not hidden within an outer case, but 

 shows distinctly the legs, wings and other external features of the future 

 fly, and, moreover, remains within the fruit — the fly emerging from it and 

 escaping through the opening previously made by the codling-moth 

 caterpillar.
