6 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 94 



appear to have disappeared from the collection. These are: Ainara 

 inarylandica, Amercedes stihidirostris^ Bcmbidion militare, Celia fer- 

 ruginea, Celia pallida, Epipocus punctipennis, Euuiononycha opaca, 

 Euplectus impressiceps, Lathropus piibescens, Laemophloeus flori- 

 danus, L. horni, L. schwarsi, Phyllopliaga suhpruinosa, Ptilium sid- 

 catuni, Stenolophns gracilis, Stethoharis cicatricosa, Tachys occidator, 

 Telephanus lecontei, Thesium laticolle. The disappearance of most of 

 these types is referred to by Casey in Memoir 5, page 283, 1914, and in 

 Memoir 8, page 291, 1918. The types of two other species, Colon decoris 

 and Trichopteryx fungina, which were at one time thought by Casey to 

 have been lost (Memoir 5, p. 283, 1914, and Memoir 11, p. 155, 1924), 

 were located during the progress of the curatorial work on the collec- 

 tion, the former among a lot of small Silphidae, the latter in the set 

 of Acratrichis parallela Mots. In addition to Casey's own types, the 

 collection contains type material of 100 or more species of various 

 other authors. 



Shortly after the public announcement of Casey's bequest of his 

 collection to the National Museum, tentative plans were made looking 

 toward the future care and upkeep of this notable accession. Details 

 of the preliminary arrangements that led finally to my appointment as 

 Specialist for the Casey Collection of Coleoptera under the Smith- 

 sonian Institution are outlined in the foreword to this article. The 

 main objective was to transfer the Casey material from the over- 

 crowded original boxes to standard Museum insect drawers, with each 

 species segregated in an individual cork-lined box or tray. Until this 

 transfer of material could be accomplished, the collection remained 

 sealed, as any attempt at unrestricted study of the specimens as they 

 were left by Casey inevitably would have resulted in more or less 

 breakage and confusion. The curatorial work was started by the 

 writer on April i, 1926, and was continued, half a day at a time, for 

 a period of 5 years. 



The cardinal rule guiding the curatorial work was to preserve 

 exactly Casey's concept of each species. Regardless of occasional con- 

 flict with accepted synonymy, Casey's arrangement of specimens was 

 strictly followed ; f urtherm9re, steps were taken to virtually guarantee 

 the permanent preservation of this arrangement, so that students, both 

 now and in the future, will have equal assurance that before them 

 stand Casey's actual original series of each species, and not a hodge- 

 podge resulting from accidental misplacement of specimens or inter- 



'A specimen of this species in the collection bears a label on the back of 

 which appears this statement in Casey's handwriting : " The type is in Carnegie 

 Mus. Pittsburg."
