sorted independently. But if a continuation of specific assign- 

 ments were desired, without resorting to a division of the material 

 into limited accessions, letters can be used in double standing, and 

 for further need use treble, and so forth. Such extensive demands 

 for any group, however, is a very remote possibility. 



Third. For the third series of symbols, to denote the stage or 

 inseparable stages of a species, with or without host or enemy, 

 either for rearing or preservation, use small letters as assigned 

 herewith. 



a. For adult, or mature stage. 



h. For pupa or nymph, or metamorphic stage. 



c. For larva or young, or larval stage. 



d. For egg or ovum stage. 



e. For inseparable stages, as in colonies. 



Fourth. For the fourth series of symbols, to specify a separate 

 specimen, pair or colony of any previously designated species,with 

 regard to particular or collective stages, either to be preserved or 

 else isolated for observational purposes, use Arabic figures in con- 

 secutive order. 



SUMMARY. 



An explanation of the entire plan for use of symbols may be 

 summarized by steps composing the following course of procedure: 



All insects contained in an accession are first sorted into super- 

 ordinal 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 consecu- 

 tive order as desired for special designation. Arabic figures are 

 used for numbering. 



Example explained : l.V.A.a.l. 

 1. Denotes first accession. 



l.V. Indicates an assortment of insects belonging in the superordinal 



group Coleopteroidea, as found in the first accession. 

 l.V. A. Indicates the first specification of species sorted out from the 



previously designated group. 

 l.V.A.a. This refers the designated species to the adult stage, should 



such be the case. 

 l.V.A.a.l. Denotes first isolation or particular specification of one or a pair 

 of adults as previously designated.
