Report on the Articulata, by P. R. Uhler. 



INSECTS. 



Since the last Report, considerable work has been done in 

 reducing the extensive collections of insects to a state of order 

 and security, as well as in adding series of specimens required 

 for exchange. 



Having been sent to Hayti during the spring of the present 

 year, to collect the insects, &c, of the south-west extrem- 

 ity of the island, I was enabled to bring together a pretty fair 

 representation of the fauna of that region. On my return 

 in June, it was thought desirable that I should proceed to 

 Maryland, for the purpose of procuring specimens, to assist in 

 conducting the exchanges during the present autumn. I suc- 

 ceeded in procuring by my own collecting, and by purchase, 

 about 10,000 specimens, many of which were new to the 

 Museum collection. 



As fast as received at the Museum, the lots have been 

 assorted into their . respective sub-orders, and a series set 

 aside for the faunal and systematic collections. Large numbers 

 of boxes now contain the series so separated for the different 

 collections, and would the space in the Museum permit, hun- 

 dreds of these boxes could be at once placed on exhibition. 

 Only a few boxes of Australian insects have, accordingly, been 

 placed in one of the cases in the gallery. My absence from the 

 Museum during a considerable part of the year, has prevented 

 the final arrangement and mounting of the remainder of our 

 dried specimens, but some progress has been made, notwith- 

 standing. 



The Myriappda sent to Mr. Wood for determination, have 

 been returned with their names appended. 



The exchanges promise to be a fruitful source of enlargement 

 to the collections, and the few returns, thus far made, have 

 added many fine species. 



The additions to the collections have not been so great as in 

 1864 ; but that extraordinary increase was due to the purchase 

 of several large collections brought together by eminent 

 entomologists. 



The whole number of specimens added since the last report 

 is 21,132, embracing 7,464 species. Of this number, 2,870
