DISTRIBUTION. 



Accepting the synonymy given above, the localities in whicli'- 

 this species lias been recognized may be summarized as follows: 



Colorado. ( Chambers. ) 



Illinois. Bond, Champaign, Crawford, Edwards, Effingham, 

 Jackson, Jefferson, Madison, Marion, McLean, Montgomery, Monroe,. 

 Eandolph, St. Clair, Wabash, and Washington counties. (Weed.) 



Kentucky. Kenton Co. (Chambers.) 



Massachusetts. Essex Co. (Packard.) 



Michigan. Ingham Co. (Weed.) 



New York. Tompkins Co. (Brunn.) 



This insect, like most leaf miners, may very readily be dissemi-- 

 nated by the leaves that occasionally remain attached to young 

 fruit trees during winter. 



LIFE HISTORY. 



The life history of this insect may be briefly characterized as 

 follows: The grayish brown moth lays its eggs on the leaf, and 

 the young larvae as soon as hatched begin eating the parenchyma 

 of the upper side of the leaf. When full grown they leave their 

 old mines and make new ones by turning over the edges of the 

 leaves. Here they pupate, and in a short time emerge as moths. 

 They usually pass the winter in the pupa state, though, from the 

 fact that I have found untransformed larvae as late as November 

 24, I suspect that they may occasionally hibernate as larvse. 



PARASITES. 



Mr. Brunn bred two species of parasites from the apple Ornix — 

 Sympiezus litJwcolletidid, Howard, MSS=, and Eulophus minuius, 

 Howard, MSS. We have bred from it a single undetermined chalcid, 

 and a great number of a new species of Apanteles which I have 

 described under the name of Ap}mteles, ornigis.^ These parasites' 

 spin peculiar, banded, white cocoons which are swung like ham- 

 mocks within the leafy cocoons of the host. 



REMEDIES. 



The remarks concerning remedies for the apple Tischeria apply 

 with equal force to the present species.
