same thino; in the past, but, supposing that these hirvpe were a stage 

 of the berry moth, had taken no further notice of them. The atten- 

 tion of Mr. Swezey was called to the matter b}^ Mr. Maxwell, on 

 June 20, and the insects proved to be a new enemy to the grape and 

 probably one hitherto unknown to science. As affected buds are 

 ruined the clusters are made irregular, and as one-fifth of the buds 

 were found infested in some cases it resulted in considerable loss. 

 Fifteen larvae have been found in a single bud and as high as twent}^- 

 five infested buds have been found in a cluster. The larvae undoubt- 

 edly complete their transformations in the ground, A^hich makes it 

 very difficult to trace their complete life histor}^ but from their 

 structure it is evident that the^^ belong to the dipterous family Cecido- 

 myiida^ and are closely related to the Hessian fly. Later it was 

 learned that this insect had been found also in the Chautauqua grape 

 belt in New York on June 12, 1904, by Mr. Fred Johnson, who was 

 working on grape pests with Prof. M. V. Slingerland. I am in- 

 formed also by Dr. E. P. Felt that he has foinid it in New York 

 vinej^ards this year. 



An outbreak of the elm leaf -beetle {GaleruceUa luteola Miill.) Avas 

 discovered by Mr. George A. llunner at Dayton, late in August. 

 Euroi^ean elms were badly infested, and, in some parts of the city, 

 American elms were being defoliated. It was impossible to deter- 

 mine how long the insect had been present, but a subsequent examina- 

 tion showed that it was attacking elms in many different sections of 

 the city. This is the first record of its occurrence in Ohio, and careful 

 search in other cities in the State has failed to reveal its presence. 



The Hessian fly {Mayetiola [Cecidomyia] destructor Say) has made 

 its appearance in the wheat fields this fall, and according to some of 

 tlie crop corres]:)ondents is more abundant than usual. The present 

 prospect is that considerable damage will result to the next wheat 

 crop. 



INJURIOUS INSECTS IN MINNESOTA IN 1904. 



By F. L. Washburn. »S7. Anflwny Park, Mitni. 



AYhile the year has been uneventful as regards insect outbreaks 

 in the usual looked-for directions, it has nevertheless contained some 

 surprises. There has been practically no trouble from the Hessian 

 fly {MayethJa [Cecidomyia] destructor Say) in any part of the State, 

 as far as the entomologist can learn, the preceding ^-ear, 1903, wit- 

 nessing the culmination of its increase. We have every reason to 

 believe that it will gradually grow more abundant in the next few
