Psyche 
[Vol. 87 
For examination of genitalia, either the terminal abdominal 
segments or the entire abdomen was removed and treated with 10% 
KOH at room temperature for 2-10 hr. In some cases, specimens 
were placed in a cleaning sonicator for a few seconds, but this was 
too severe a treatment for general use. Specimens were then washed 
with water and placed in glycerol. 
A dissecting microscope at 95X magnification was used for 
determination and for illustrations. A Zeiss Photomicroscope II® 
was used for more detailed examination at magnifications up to 
400X. 
Illustrations were prepared freehand with the use of a counting 
grid mounted in one ocular of the dissecting microscope. Measure¬ 
ments are accurate to .04 mm. Illustrations are accurate to .02 mm. 
After examination and illustration, all specimens which had been 
dissected for examination of genitalia and all specimens which were 
fragile and/ or broken were placed in glycerol in genitalia vials for 
permanent storage. All other specimens were placed in vials of 80% 
ethyl alcohol with a few drops of glycerine. 
Specimens used in this study were from the collection of the 
author (AUTH) or borrowed from one of the following collections: 
Arizona State University (ARIZ), Illinois Natural History Survey 
(INHS) or Utah State University (UTAH). Types were deposited in 
one or more of these collections or in the National Museum of 
Natural History (USNM). Meinander (1972) types are deposited in 
the California Academy of Sciences (CAS), University of California 
at Berkeley (UCA) or the National Museum of Natural History. 
Classifications and Descriptions 
Due to the recent world revision by Meinander (1972), some 
material which is readily available in that revision was omitted from 
this study. Synonomies were limited to original descriptions and to 
publications after 1972. In the interest of standardization, I have 
followed Meinander’s format regarding descriptions and illustra¬ 
tions and have used the same terminology where possible. I have 
noted my differences in interpretation from Meinander. I have 
prepared illustrations of previously undescribed species and other 
species where necessary. 
The descriptions include only those characters which have been 
found to vary within the genus. Keys are provided to the species.
