ROUTINE WORK. 



The routine work during the year has been : 



1. The making up of collections for exchange. Some of these are: 

 A series of named Coleoptera for Mr. Charles Palm, of New York; a 

 small series of named Coleoptera for Prof. Paul Noel, Eouen, France; 

 a large series of named Coleoptera for Prof. A. J. Cook, Lansing, Mich. ; a 

 series of Coleoptera for Mr. Chailes Bury, Cincinnati, Ohio; a series 

 of Hemiptera for Prof. A. L. Montandon, Bucarest, Roumania. 



2. The naming of s])ecimcns for collectors. Numerous larger and 

 smaller series of insects of all orders have l)een identified for a number 

 of correspondents. 



3. The selection of material to be sent to specialists for study and 

 determination. 



{a) The Coleoptera of the family Cistelida^ were sent to Capt. T. L. 

 Casey, New York, who has recently monographed this family. 



(h) A series of all the forms of the Buprestid genus Agrilus has been 

 selected and sent to Dr. G. H. Horn, of Philadelphia, who offered to 

 identify them according to his newly prepared, still unpublished revi- 

 sion of this genus. 



(c) A large series of the Dipterous family TachinidiTP, representing all 

 the species in the collection, except uniques, has been prepared and 

 sent to Prof. Frederick Brauer, of Vienna, who has published ar new 

 classification of the Calyptrate Muscidie of the world, but ])robably 

 from lack of material at his disposal, our North American fauna in this 

 group has not been satisfactorily elucidated. 



(4) The work of arranging iu permanent shape all the collections. In 

 the Lepidoi)tera the Noctuidie faseiatie, the Tineiua, and the biologic 

 series have been rearranged and accessions have been incorporated in the 

 Rhopalocera and Bond)yeina. In the Coleoi)tera, which in the last re- 

 port were stated to have been completely arranged, the incorporation 

 of the vast accessions has necessitated a con.siderable expansion of the 

 collection. In the Hemiiitera the accessions have all been incorporated 

 in the collection. In the Diptera the great bulk of the families have 

 been arranged during the year, occupying about 220 unit boxes, but a 

 number of the more obseure and dihicult families are still mixed and 

 unidentified.
