452 EXPEEIMENT STATION RECORD. 



A system of notation applied to entomological accessions, E. S. Tucker 

 (Trans. Kans. Acad. 8ci., 26 {1912), pp. 142-145). — "An explanation of the 

 entire plan for use of sj-mbols may be summarized by steps comiX)sing tbe fol- 

 lowing course of procedure : All insects contained in an accession are first 

 sorted into superordinal groups as a basis of classification. Each, group is then 

 designated by a Roman numeral according to the assignment given. The 

 second step consists in separating the species in each group and indicating each 

 species by a capital letter. In the third step the separate or collective stages 

 of each species are determined, and designated by a small letter, as per assign- 

 ment. Finally each specimen or pair with respect to one stage, or colony with 

 respect to collective stages, is numbered in consecutive order as desired for 

 special designation. Arabic figures are used for numbering."
