(6) Mounting, expanding, and labeling specimens for the collection. 

 Much time is taken up by this work, as a large percentage of the acces- 

 sions arrive unmounted and all have to be labeled before distribution 

 in the collections. 



RESEARCHES. 



Most of the special researches based upon museum material are 

 mentioned under the paragraph relating to routine work. In addi- 

 tion to these, however, Mr. W. H. Ashmead has completed his mon- 

 ograph of the Proctotrypidse of North America, based very largely 

 on Museum material. This is the first monograph written upon the 

 American representations of this group. 



Dr. George Marx has had at his disposal the Acarians of the family 

 Ixodidie, belonging to the collection, and is engaged upon a monograph 

 of the family. 



PRESENT STATE OF THE COLLECTION. 



Daring the last year about 10,000 specimens have been added to the 

 collection. The last catalogue entry for June, 1891, is 740, and for 

 June, 1892, is 1,041. The whole collection was carefully examined for 

 museum pests during the month of June, and was found to l>e in a 

 highly satisfactory condition.
