APPENDIX I 

 Collection Data 



The data for collections made during this study are presented in the 

 following list. Entries are arranged chronologically under each species, 

 subspecies, or intermediate. References to these collections in the text 

 are made by collection numbers, but it should be evident from the 

 context which species, subspecies, or intermediate in this list should be 

 examined to find a given collection. The Mendocino-Trinity and Aspen 

 populations of A/, calif ornicum are included under A^. calif ornicum. Where 

 subspecies are involved, most collections were classified as the subspecies 

 which the majority of the specimens most closely resembled, rather 

 than as intermediates, since the fact that they are regarded as subspecies 

 implies the existence of intermediates in most continental situations. 

 Intermediate populations occur in all boundary areas unless it is 

 specifically mentioned in the comments or distribution under each 

 subspecies that they were not found. 



Following the date the letters "E" (eggs), "L" (larvae), "P" (pupae) 

 or "A" (adults) may be found. These indicate which life stages were 

 collected and/or reared. The number in parentheses after the "E" in- 

 dicates how many egg masses v/ere collected in the immediate vicinity 

 on one or more hosts. The available information about Malacosoma egg 

 masses indicated they were laid in a characteristic way for some species 

 (see the section on egg masses, page 20). Therefore, an effort was 

 made to find several egg masses at each locality (on one or more hosts) 

 in order to obtain this information for each population, and to obtain 

 some idea of the variability that could be expected in such populations. 

 If the number is divided (4/2) it means that 4 egg masses were found 

 which did not have any specks in the spumaline, and 2 were found 

 which contained specks. An asterisk (4/2*) indicates that part of the 

 egg masses which contained specks had relatively few. Undivided 

 numbers (4) mean none of the egg masses had specks in the spumaline. 

 A "P" indicates that some cocoons were found in the area. 



After the "L" the numbers 1, 2, 3, 4, or 5 may be found. These 

 numbers indicate the instar(s) which were present on the date the 

 collection was made (ignoring the possibility that six instars may some-
