122 REPORT OF NATIONAL MUSEUM, 1887. 



mens, and 237 drawings, most of them made for this series, and many 

 of them original. 



The Arachnida were still mostly contained in jars and vials of all 

 kinds and sizes, and the species were sadly mixed. They have all been 

 assorted, and placed in the standard vials adopted by the curator. The 

 material in the adolescent stages of insects was in somewhat similar 

 condition and was similarly treated. 



Several small lots of named Myriapods received, as noted in the list 

 of accessions, were also mounted and temporarily arranged. In this 

 class the Museum collection has an unusual number of types. 



During a portion of the summer Mr. A. S. Davis, of Mount Pleasant, 

 served as a volunteer in the department, and with his aid a large lot of 

 material previously mounted was labeled and separated and the balance 

 of the old material was mounted. 



Mr. W. H. Crane, of Cincinnati, also served in the department for a 

 short time this year, and his aid was effective in the arrangement of 

 the Diptera and in the synoptic collection of Coleoptera. 



The Orthoptera were arranged in two cabinets, occupying forty 

 drawers in all. Of some groups drawings, illustrating specific distinc- 

 tions, were made and pinned into the collection with the species. 



Prof. P. E. Uhler has been for some time studying the Capsidse 

 (Hemiptera Heteroptera) of the United States, and offered to arrange 

 and name the Museum material in the family. 



The material was therefore carefully looked out and sent to Professor 

 Uhler, who finds many new and interesting forms. Some of these he 

 has referred to in describing new species in Entomologica Americana, 

 but none have as yet been returned by him. 



So far as the more pressing work would allow, progress has been 

 made in the studies of the Noctuidae in furtherance of the monograph 

 in preparation by myself and Mr. J. B. Smith. The latter has also 

 made a study of the material in the lepidopterous family Saturniidse, 

 and the results are published in the Proceedings of the U. S. National 

 Museum, 1886. He has also studied the lepidopterous genus Calli- 

 morpha, and the results are embodied in a paper presented for publica- 

 ing in the Proceedings for 1887, but not yet issued. The genus Euery- 

 thra was also studied in the same way and a paper prepared and pre- 

 sented, but not yet published. 



These papers contain many new facts of interest in structural Lepi- 

 dopterology that have resulted from a careful study of the material ; 

 but the conclusions, especially in the Callimorpha and Uuerythra pa- 

 pers, sometimes run counter to my own convictions and to the facts 

 from the biologic side. 



The curator's researches, so far as they are indicated by publication, 

 have been as heretofore mostly in connection with his work for the 

 Department of Agriculture, and are indicated in the bibliography.*
