NO. 3 CASEY COLLECTION OF COLEOPTERA — BUCHANAN 7 



polation of later and irrelevant material. Casey's arrangement was in- 

 dicated by attaching to each specimen a label giving the specific name 

 of the species and its sequence in the series, as, mtnuu'^f " Sinuta'^f " 

 mlnuu^f"' Each species was then placed in a suitable-sized tray on 

 which appears the full scientific name. No material is to be added 

 to these trays, and none is to be transferred, except in a few special 

 cases. 



In addition to the " Casey det." and type labels, used of course 



only on identified material, a small pin label bearing legend bequest 



1925 



was attached to every specimen in the collection, named or unnamed. 



Also, a record of all the North American species in the collection 



was entered in a copy of Leng's Catalog of Coleoptera. 



When the work of arrangement had been completed, a manuscript 

 catalog of the entire collection was prepared by Miss Marie Siebrecht, 

 working under my direction, that will serve as an historical record 

 for future reference should any question arise as to any of this 

 material. Data in this catalog are arranged systematically, the order 

 of genera and families being essentially that of the Leng Catalog of 

 North American Coleoptera, The list gives the total number of 

 specimens for each species, with indication of types. A synopsis at 

 the end serves as an index to the families and to the number of speci- 

 mens that these include. The collection as thus recorded is found to 

 contain 19,245 named forms, with a total of 116,738 specimens, and 

 more than 9,200 holotypes. 



It is well known that Casey did not make a practice of marking the 

 types in his collection. The various terms now in common use to 

 distinguish different categories of type material were not uniformly 

 applied by Casey in his writings ^ and very seldom used on the speci- 

 mens themselves. However, Casey did make the verbal statement that 

 the specimen bearing the name label was to be considered the true 

 type, as shown in this extract from a letter of November 3, 1927, from 

 J. C. Crawford to Dr. Alexander Wetmore, Assistant Secretary, 

 Smithsonian Institution : 



About ten years ago Dr. Hopkins and I visited Colonel Casey at his request 

 to see both his collection and the conditions under which he worked. At that 

 time both Dr. Hopkins and I complained to Colonel Casey of the types in the 

 Casey Collection not being labeled. Colonel Casey made the statement, which
