Proceed cautiously when using diagnoses based upon very small 
samples. In Tables i and 2 the diagnostically most useful character 
values are circled for each species or group of species. 
Descriptions. The quantitative character values recorded in Tables 
i and 2 are an essential part of each species description. Each descrip- 
tion is a composite of all adult specimens at hand. Only characters 
of at least some diagnostic value are included. Colors are described 
from fully sclerotized specimens dead for two months to six years 
and immersed in alcohol under strong fluorescent light. 
Illustrations. Illustrations were carefully drawn in pencil on 
translucent paper over a squared grid template with the aid of a 
squared grid reticle in the eyepiece of the Wild M-5 stereomicro- 
scope. The penciled drawings were then traced in ink on heavier 
paper. Nearly all figures of seminal receptacles are drawn from re- 
productively active females. 
Variation discussions. For each species, variation of all 63 male 
quantitative characters, all 76 female quantitative characters, and a 
number of qualitative characters was examined, and all characters 
which show marked variation are discussed. The sizes of all popula- 
tion samples discussed can be found in the modified Dice-Leraas dia- 
grams or in the records section. 
Records. Only specimens which I have examined are listed. 
Within each county citation, all records from a given locality are 
separated from those of other localities by a dash. Collection dates 
are listed only for males. When a male symbol is surrounded by 
parentheses, it means that the specimen was collected when immature 
on the date given and matured later in captivity. When no male or 
female symbol follows a record, this means that only immatures were 
collected.
