A new arrangement of the biological collection of the Coleop- 

 tera, to introduce the collection presented by Professor Schaupp, 

 had to be postponed for want of cabinets. 



A large collection of Neuroptera from Samana Bay, Haiti, 

 made by Mr. Frazer, was bought and presented to the Museum. 



A large lot of Odonata, from the North Guinea Archipelago, 

 Central Asia, South Africa, Peru, and Brazil, was bought and 

 presented to the Museum. 



Numerous additions by private students, or by exchange, 

 have, as usual, enlarged the collection. By exchange were added 

 Lepidoptera, from Arizona and Himalaya, by Mr. B. Neumoegen, 

 New York, and Neuroptera, by Mr. Aaron, Philadelphia. 



The collection has been largely used both here and abroad. 

 The Myriapodes are still in Dr. Meinert's hands, half of them — 

 the Chilopoda — ready for publication. North American Arach- 

 nids are still in the hands of Count Keyserling. The second 

 volume of his Spinnen Amerika, Theridiidae, Nurnberg, 1884, 

 is just published, a handsome quarto volume of 221 pages and 

 10 colored plates. Of the Scorpions a dozen Unica are still in 

 Mr. Simon's hands, in Paris, for publication. 



The Ephemerina have been returned by Mr. Eaton from 

 England. Two parts of his splendid monograph are published ; 

 with the third concluding part, the monograph will fill a whole 

 volume of the Transactions of the Linnsean Society of London. 

 On nearly every page the material supplied by the Cambridge 

 collection is mentioned. 



The larger part of the North American Tineinae have been 

 in the hands of Prof. H. Frey, in Zurich, Switzerland. They 

 were safely returned with the notes of Prof. Frey. A prepared 

 publication had to be postponed by his illness. 



Mr. P. R. Uhler has studied and determined the Hemiptera 

 collected in 1882 in Washington Territory. 



Mr. J. B. Smith, of Brooklyn, New York, has studied and 

 published the Sat} T ridae collected in 1882 in Washington Terri- 

 tory (in the Bulletin of the Brooklyn Entomological Society). 



Mr. L. Brunner has studied the Orthoptera collected in 1882 

 in Washington Territory. 



The Assistant has published a number of smaller papers ; 

 among them, the remarkable discovery that the Hessian fly 

 was known by this name, and by its ravages, in 1768, long
