118 REPORT OF NATIONAL MUSEUM, 1887. 



A lot of typical Myriapoda, received from Mr. Eathbun, the curator 

 of Marine Invertebrates, has been carefully preserved and arranged. 



A lot of slides containing parts of insects and many minute species, 

 also from Mr. Eathbun, were carefully listed and arranged for ready 

 reference. 



The Heteroptera had been arranged by Prof. H. Osborn, as detailed 

 in the last report, but the duplicate material had neither been labeled 

 nor entirely separated ; this unfinished work on the suborder was also 

 done during the year. 



The Capsidce, one of the families of this order, was sent to Prof. P. E. 

 Uhler, of Baltimore, for study, at his request. 



The collection of Orthoptera had already been carefully arranged by 

 Mr. Lawrence Bruner while associated with me at the Department of 

 Agriculture, in 1884, in a series of single and double folding boxes; 

 but in order to assist in the preparation of a monograph of the Acrididw, 

 which I have planned with Mr. Bruner, the whole order has been trans- 

 ferred to permanent cabinets. This re-arrangement has permitted the 

 incorporation of the new material that has accumulated since 1884, and 

 has placed the collection in far better condition both in regard to safety 

 from breakage and to facility for study. In the re-arrangement a dupli- 

 cate series was also prepared for the Department of Agriculture to facili- 

 tate reference work there. 



Eeports on accessions often require considerable study and time, and 

 the correspondence of the department has been extensive. 



A considerable amount of time was occupied in determinations for 

 such entomologists as either sent specimens for the department or who 

 had in some way deserved well of the Museum, and for institutions 

 where the determinations would be valued and valuable. 



Some twenty such lots were named in addition to those which were 

 reported upon as accessions in the regular manner. 



During the year two additional standard cabinets of the kind de- 

 scribed in my previous report have been made. These are of cherry 

 and mahogany, and superior to those previously received. 



One hundred of the standard single folding boxes were also ordered 

 and received. 



The Smith collection is contained in one large walnut cabinet of sixty 

 drawers ; a small pine cabinet of nine drawers ; 80 single folding boxes; 

 27 pine double folding boxes ; 17 very large walnut double folding boxes, 

 and a miscellaneous lot of over 100 boxes of all sizes and shapes. Two 

 unit table cases were also assigned to the department. 



A very fair proportion of the boxes received are already in use, and 

 they are being rapidly filled as arrangement of material progresses. 



The preparation of papers for publication, as a direct result of the 

 Museum work, has occupied, compared with the other work, but a small 

 part of the time. It is chiefly represented by the paper by Mr. Smith 

 on the classification of some of the Boinbycina in the Proceedings of
