showed that, in several instances, a seed had been transfornied from 

 its normal alate shape into a globose gall, and displayed on its side 

 a round spot where the shell had inwardly been eaten to a thin 

 pellicle to admit of the escape of the contained insect. The insect 

 within was found to be a mature larva, apparently nearly ready 

 for its pupation. It was evidently a Cecidomyian. In May, 

 examples of the perfect insect emerged from the galls, and were 

 reterred to the genus Cecidomyia. No United States species cor- 

 responding to it was known. It was given a manuscript name of 

 C. hetulce, but before publication it would be proper to compare it 

 with the European forms. It was accordingly sent to Baron Osten- 

 Sacken, of Heidelberg, Prussia, our authority in North American 

 Diptera. Answer was returned by him, that careful comparison 

 showed it to be absolutely identical with the Cecidomyia letulat, of 

 Europe, as described by Winnertz. 



My principal collections of the year were made during a two- 

 week's sojourn at Keene Valley, in the Adirondack mountains, 

 in the month of August. The locality proved quite unfavorable 

 to large collections. The Lepidoptera and Coleoptera were but 

 few in number. The Hymenoptera and the Hemiptera, constitut- 

 ing the bulk of the collection, were almost entirelj' confined to the 

 golden-rods, tor the spiraeas which in the previous year I had found 

 so attractive to these forms, were not in bloom at " Beede's," at 

 the upper end of the valley, although it was met with in full flower 

 on my return at three hundred feet lower of elevation. As there 

 has not'yet been the opportunity for studying the insects obtained 

 at the time, I am unable at the present to offer any special report 

 upon them. It is believed, however, that niany interesting forms 

 have been secured, a few of which may prove new to science. 



The additions to the Department by contribution will be given 

 in the concluding pages of this report. 



With the above general remarks, the following notices of several 

 insects and insect attacks, which it is hoped will be of interest and 

 value to our agriculturists and others, are 



Respectfully submitted,
