REPORT ON INSECTS. 



By Dr. H. A. Hagen. 



The additions to the collection have been larger than usual. 

 The most prominent are a very large lot of prepared caterpil- 

 lars and Lepidoptera from Dr. 0. Staudinger, Dresden, Saxony 

 (bought) ; a splendid lot of United States Lepidoptera with its 

 previous stages from Mr. H. Edwards, New York (presented) ; 

 a large collection of insects of different orders from Japan, from 

 the museum in Tokio, Japan (exchange) ; a collection from Him- 

 alaya by Dr. Williams, Jr., Boston (presented); and very large 

 and valuable additions to the United States collections by Mr. 

 H. G. Hubbard, Detroit, Mich., and Mr. Charles Dury, Cincinnati, 

 0. (exchange). 



The condition of the collection is very satisfactory, no pests 

 having been observed. Special attention has been given to the 

 advance of the United States collection. The Coleoptera have 

 been revised kindly by Dr. George H. Horn ; this collection con- 

 tains now two thirds of the hitherto known United States species, 

 represented by good specimens determined by prominent authori- 

 ties. The same can be stated for the United States Lepidoptera, 

 which has been enlarged by typical specimens presented by H. 

 Edwards, R. Thaxter, E. L. Graefe. 



The exceedingly ricli additions to the Biological collection will 

 require a rearrangement of a large part of the Lepidoptera, Neu- 

 roptera, and Pseudoneuroptera ; but other parts also begin to be 

 densely crowded. The Biological collection is finished and in 

 exhibition, except for the Orthoptera and a part of tlie Hemiptera. 

 A number of valuable additions have been received from Dr. J. L. 

 Le Conte, Dr. George H. Horn, Mr. Th. Meehan, Philadelphia; 

 Professor J. A. Cook, Lansing, Mich. ; Mr. T. Henshaw, Boston ; 

 Mr. H. Edwards, New York ; Miss Cora Clarke, Boston ; Miss 

 E. Smith; Peoria, 111. ; Mr. J. A. Lintner, Albany, N. Y. ; Mr.
