Yponomeutidce. 



A few forms in this family require mention. Yponomeuta mali- 

 nellus Zell. Y. evonymellus L. and Y. padellus L. are recognized as of 

 considerable importance to orchardists in England and portions of 

 Europe, especially the first mentioned, which has just made its 

 appearance in the United States near Geneva, N. Y. Y. padellus 

 feed on plum and cherry in France, and on plum in Italy. Prays 

 citri Mill, infests the orange in Corsica, Sicily, Ceylon and Aus- 

 tralia, and recently it has been received from the Philippines. 

 P. oleelus F. injures foliage of olive in Italy, and ranges over the 

 Mediterranean region, where the olive is cultivated. In the genus 

 Argyresthia are several suspicious characters. A. conjugella Z. 

 is already established in British Columbia and has been taken in the 

 Puget Sound region in Washington State. The slender larvse tun- 

 nel apples and other fruits. It ranges over central and southern 

 Europe, Asia Minor, Japan, etc. A. nitidella Fabr. is the cherry 

 fruit moth of England, the larvse burrowing in the fruit. A. ephip- 

 pella F. feeds on the shoots of cherry, the leaf and blossom buds of 

 wild plum, also on the hazel. A. cornella F. attacks the leaf buds 

 of apple. 



GelechiidcB. 



Gelechia gossypiella Saund. is another serious cotton pest and is 

 almost universally distributed over India, Ceylon, Burma, Straits 

 Settlements and East Africa. It has just now been found in 

 Hawaii. It is known as the pink bollworm. and is generally asso- 

 ciated with the spotted bollworms. The larvae also bore into the 

 bolls and feed on the oily seed. Anacampsis nerteria Meyr. is 

 injurious to ground nuts in Ceylon and South India, and is ap- 

 parently quite important. Anarsia ephippias Meyr. also feeds on 

 the ground nut in India and has been taken only during the rains. 

 It feeds upon and rolls the leaves together. 



Elachistidoe. 



The pith moths, Blastodacna hellerella Dup., and B. vinolen- 

 tella H. S. are insects whose larvae cause a good deal of damage 

 to apple trees, especially nursery stock. The larvse bore into the 

 buds, spurs and shoots, thus causing the foliage and shoots to die. 

 The species work something like our Epinotia pyricolana Murtf. 

 Antispila rivillei Stt. injures grape foliage like our A. Isabella and 

 occurs in northern and middle Italy and Dalmatia. Coleophora 

 anatipennella Hbn. the cherry case bearer, injures cherry buds in 

 the spring time in England and occurs over central and northern 

 Europe. C. flavipennella HS. injures pears in Europe in a similar 

 way, while C. hemerobiella Z. feeds on apple, pear and cherry,
