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, Theridiide, 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 Linnzan Society of London. 
On nearly every page the material supplied by the Cambridge 
collection is mentioned. 
The larger part of the North American Tineine have been 
in the hands of Prof. H. Frey, in Ziirich, 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 Satyridz 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
