REPORT OF THE ENTOMOLOGICAL DEPARTMENT. 



By II. A. IIa'.kn. 



The additions to the collection consist of some types of Lord 

 Walsingham's N. A. Tineina presented by Mr. V. T. Chambers 

 of Covington, Ky., and the large collection of insects presented 

 by the Northern Pacific Railroad Transcontinental Survey. As 

 the insects have been collected in one of the districts of the 

 United States, not previously visited by entomologists, Washing- 

 ton Territory east of the Cascade Mountains and north of tho 

 Columbia River, — they are of importance, and fill large gaps in 

 the collections of North American insects in the Museum. 



A large number of insects have been spread, and the rearrange- 

 ment of the large collection of Odonata has nearly been finished. 



Facilities for examining parts of the collection have been 

 granted to specialists and students. Professor H. Osborn of 

 Ames, Iowa, worked here three months, and several ladies have 

 studied N. A. Lepidoptera. The assistant has lectured on general 

 entomology to five students and one lady. 



The following gentlemen have received materials for their pub- 

 lications from the Museum collection : Rev. A. B. Eton. Croydon, 

 England, on the Ephemerina. A part of his results are published 

 in the Entom. Monthly Magazine, London. The work will be 

 published by the Royal Society, London, with a large number of 

 plates in 4to. 



Dr. Vayssiere, Montpellier, has published the remarkable 

 nympha of Baitisca obosa. similar to Prosopistoma, in his mon- 

 ograph of the early stages of Ephemerina in Ann. Sc. Nat. Paris 

 from specimens of our collection. 



Count Keyscrling has published in Wien. Zool. Bot, I 

 number II. on American Spiders, based partly upon specimens of 

 the collection. 



As usual, correspondence with North American entomoloj 

 has occupied a considerable part of the time o\' the Assistant.
