same thing in the past, but, supposing that these larvae 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 by 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 larve have been found in a single bud and as high as twenty- 
five infested buds have been found in a cluster. The larvee undoubt- 
edly complete their transformations in the ground, which makes it 
very difficult to trace their complete life history, but from their 
structure it 1s evident that they belong to the dipterous family Cecido- 
myude, 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 found it in New York 
vineyards this year. 
An outbreak of the elm leaf-beetle (Galerucella luteola Mill.) was 
discovered by Mr. George A. Runner at Dayton, late in August. 
Kuropean 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 (J/ayetiola | Cecidomyia| destructor Say) has made 
its appearance in the wheat fields this fall, and according to some of 
the crop correspondents 1s 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, St. Anthony Park, Minn.

While 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 (Mayetiola | Cecidomyia| destructor Say) in any part of the State, 
as far as the entomologist can learn, the preceding year, 1903, wit- 
nessing the culmination of its increase. We have every reason to 
bdelheve that 1t will gradually grow more abundant in the next few
