REPORT OF ASSISTANT SECRETARY. 161 



(rt) lieserve collection.'^.— In the IHptcra, learranjfeuientH have been made, i)iiii(ii)all.v 

 in the iainilies Tacliinifhr and liombynidw. To the Lepidoplcra much time has l.ueu 

 devoted in all groups, l.oth in the systematic and biologic series. In the Coleopfera 

 several groups like the Kumolpini and Hijdrohimi lia\c been rearran"-ed. In the 

 Hymenoptcra accessions have been incori)orat((l. In the Ifomoptera all the unar- 

 ranged material has been incorporated and the entire collection has been arranged. 

 {b) Duplicate collections.— The^^o are generally arranged in connection with tiie cor- 

 responding reserve collections, but an exception was made this year in selecting a 

 special series of North American Colcoplera, containing two specimens each of all 

 the species (2,'212) available frnm the general duplicate collection. This will facili- 

 tate exchanges. 



(c) Exhibit collecfions.—In order to temporarily fill up the vacancies in the Museum 

 exhibition hall caused by the transportation to Chicago of the larger portion of the 

 nniterial, 56 exhibit boxes were prepared from duplicates of native and exotic insects. 

 At the beginning of the fiscal year a series of Xorth American insects were selected, 

 showing 181 species that have more commonly-used vernacular names. These were 

 arranged in 7 boxes and put on exhibition. 



Several of the papers by the curator, enumerated in the Bibli()grai)hy (.\ppendix 

 VII 1, are based largely on Mu.seum material. Dr. A. S. Packard, who is engaged m 

 the study of the North American Bombycid moths, has beeu allowed free study of 

 the Museum collection, and was granted the loan of siu-h species as requir.'d a. more 

 detailed investigation. Various papers have already appeared in the Canadian Ento- 

 mologist and in the .lournal of the New York Entomological Society on this sub- 

 ject. Mr. William Fox, of the Academy of Natural Sciences, Philadelphia, has 

 borrowed the collection of the genus Tri/poxelon of the family Pemphrcdouula; to 

 assist him in his review of this group, published in the Transactions of the Ameri- 

 can Entomological Society. Prof. A. L. Monlandon, of Bucharest, Roumania, has, 

 by exchange material from the Museum, been assisted in studying the North Ameri- 

 can Hemiptera-Heteroptera, and as a result has published in the Proceedings of the 

 MiLseum, Vol. xvi, pp. 45-52, "Notes on American HemiptcraHeteroptera/ Dr. F. 

 W. Coding in his "Synopsis of the Subfamilies and Genera of the Membracida' of 

 North America-' has studied Fitch's types, e.specially in the Museum collection, and 

 his "MembracidiE of St. Vincent Island, West Indies," in the Canadian Entomolo- 

 gist for February, 1893, pp. 53-56, contains seven new species from tvpes iu the 

 Museum collection. Mr. O. F. Cook has studied tht> Lithobiidw in the collection and 

 borrowed the African Myriapods of Abbott's collection for study and special report. 

 Mr. Samuel H. Scudder has studied the Orthoptera of the Galapagos Islands, and 

 Mr. William H. Ashmead has completed a valuable monograph of the Proctotrypidw 

 based on material in the Mu.seum. Mr. L. O. Howard has continue.l his work upon 

 the host relations of parasitic Hymenoptera, and has also prosecuted certain special 

 studies on the Chalcidida; while Mr. C. L. Marlatt has be(>n engaged upon the revis- 

 ion of the Tenthredinidiv. 



Prof. Kiley also coutiibiite.s tlio followino- notice of the exliibits in 

 entomology in the Government buildino- at the World's Fair: 



The fact of the intimate connection of the Department of Insects in the National 

 Museum with the Entomological Division of the Department of Agriculture, led to 

 a certain and necessary commingling of interests in the arrangement for tlie repre- 

 sentation of the two at the World's Columbian Exposition. The main Government 

 exhibit in entomology was therefore brought together in the agricultural section of 

 the Government buildiug, and while largely devoted to the economic phases of the 

 subject, in which particular it more clos.dy represent.'d the Department of Agricul- 

 ture, it contained also a large number of exhibits purely educational or .scientific iu 

 scope, which appertained more strictly to the .Museum material and work. Of the 

 former al.so practically all the insect material was drawn from the Museum lar.relv
