The .ura[»'' fruit moth has been unusually numerous iu some \ine- 

 yards in Chautaucpia County for two or tlii-ee years, sometimes more 

 than half tlu' fruit heini;- luined. We have not yet observed the 

 spiMuu' and early summer life and habits of the i)est. In Auij^usl we 

 readily found the cirus stuek onto the skin of the fruits in various 

 h)ealities. Thex I'emind one much of tlie eodlin^ moth's ej^jj^. The 

 accepted notion has b:'en in this country that this fruit moth is the 

 same as the Kui'opean si)eeies, and that it hibernates as a i)upa in its 

 cocoon made inside a peculiar tlap cut from the h'af. In IS!)*.) an 

 exliausti\"e account of 7.') patjes about the Kuropean species apju-ared 

 in Italy." There the t,hii-d or last broo«l of larv;e si)in their hibernat- 

 ing cocoons under the loose bark of the older parts of llic vines or on 

 their supports, while the cocoons of the first and second sprinji; and 

 summer broods that work on the flower clusters and growinjj: fruits 

 are made amon.i; the flowers or on tlie leaves of <;rape and various 

 other plants. In October, r.»Uo, we made a very thorougli examina- 

 tion of many vines in a l)adly infested vineyard and failed to lind any 

 cocoons exee[)t on the fallen leaves. Kither we liave a dilVerent si>e- 

 cies from th«' Kuroi)ean .ii:rape fruit uK^th or else it has (piite a dilTer- 

 ent hibernating- habit in New York. One of the systematists who is 

 stu<lyini; this irroup of moths tells me that there seem to be at least 

 two dilb'i'eiit species now label<'<l hjinleniis Jxiiniiia in oui" collections. 

 In the .Murtfeldt eoUeelion now at Cornell I'lnversity t hei-e is prob- 

 ably the lar.i;est series of bi'cd specimens of moths under this labid in 

 this country, and it is (juite evident at a j^lance that there is more 

 tlian one species in the material. As soon as authentic European 

 material can be obtained we hope to arrive at some definite conclu- 

 sions reirarding the identity of the Anu'riean i^iape fruit n.oth. We 

 also expect to earefully compare oui- insect in its various statues to see 

 if it <'ori-esponds in all its (h'tails with tlu' many liirures i^iven f(»r the 

 Kuropean species in (Juereio's excellent work. 



Some expei-iments wei'c made durinj; the ])ast season in condiatinj; 

 this jjrape fruit moth. Some vineyardists found they could pick off 

 the conspicuous, irfested, jrreen fruits for about ^'2 per acre. This is, 

 of course, a very efTeetual method. Some vineyards were spi-ayed
