difficult group. The material has been returned in good condition. 

 Mr. Gerhard, with the aid of the Conservator, has put in fine order 

 the Hesperida? of the world. This is a part of the Martindale col- 

 lection. Much work has also been done on the other families in this 

 fine collection. Mr. Satterthwaite is engaged in rearranging the 

 exotic moths in this collection and has thus far finished the Sphin- 

 gidse. Fifty new boxes and a fine cabinet have been purchased to 

 contain the Hymenoptera and Mr. E. T. Cresson is now engaged in 

 their rearrangement. Mr. Fox has made some valuable contribu- 

 tions to science by his studies in this Order. 



Numerous specimens have been added to the cabinet, the more im- 

 portant donations being a collection of American Coleoptera from 

 Dr. Eckfeldt; 61 specimens of Honduras Lepidoptera by Dr. H. 

 G. Griffith ; 68 Hesperidse from Colima, Mexico, from Henry Skin- 

 ner ; 124 Beetles, 10 Hemiptera, 3 0rthoptera, 1 Hymenoptera from 

 Dr. A. D. Smith and the Farnum brothers, all from Manchuria ; 

 9 Coleoptera by W. F. Bednall, from Australia. 



Many valuable works have been added to the library ; nine 

 hundred and thirty-three have been the gift of the late Dr. Geo. H. 

 Horn. One hundred and seventy works have been bound. Valu- 

 able books have been purchased, some of them not being repres- 

 ented in other libraries in this country, the amount expended being 

 $529.93. The Entomological News has been continued and the 

 ninth volume completed with 264 pages and 12 plates. The present 

 space devoted to the Entomological Section is inadequate, owing to 

 its rapid growth in all departments.
