inose surface when viewed with a strong light at a low angle (caused 
by diffraction of light on the finely striate surface of small scales) 
but otherwise the species is of a reddish-to-dark brown color. The 
most distinctive character is the very long spur on the hind tibia. 
The spur is longer than the first metatarsal segment and has 
distinctly serrated fringes on two margins. Other descriptive and 
taxonomic details can be found in Horn (1880), Hatch (1930), 
Jeannel (1936), and Szymczakowski (1964), and in figures 1-7. 
Variation. Except for differing body sizes, no morphological 
variation is evident in specimens from throughout the range of the 
species. On the male genitalia, differing degrees of sclerotization of 
the paramere tips causes them to twist to differing amounts when 
dried. The setae on the internal face and ventral margin of the 
paramere tips (not drawn in figs. 6, 7) do not vary. 
Geographic distribution. The species has a wide distribution 
over most of the region covered by the deciduous broad-leaf forest 
of temperate eastern North America (fig. 8). Over this area the 
elevational range of the species is from coastal plain lowlands to 
upper elevations in both the North and South, from the White 
Mountains of New Hampshire to the Great Smokey and Black 
Mountains of North Carolina. The map is based upon specimens 
in the following collections (personal observation): Snow Museum 
(University of Kansas); Field Museum; California Academy of 
Sciences; Blatchley collection of Purdue University; Michigan State 
University; Cornell University; University of Alabama (Museum of 
Natural History); Museum of Comparative Zoology; U.S. National 
Museum of Natural History; Illinois Natural History Survey; Cana- 
dian National Collection (Ottawa); and Claude Chantal (Quebec 
City). These collections contain about 400 specimens. My own 
collection included 1200 specimens. Many of these are now de- 
posited in the MCZ, Field Museum, and Canadian National 
Collection. Literature records of Blatchley (1910), Brimley (1938), 
Leonard (1926) and Kirk (1969) have also been used on the map 
because they are probably correct in reporting on this distinctive 
species. The imprecise record for “southwestern Arkansas” of 
Hatch (1933) and the doubtful record of Jeannel (1936) for Breck- 
inridge, Colorado, have not been used. 
The forest population near Marianna in Jackson county in 
northern Florida is probably disjunct and relictual. The Marianna 
lowlands is known as a floristic relict area (Mitchell, 1963) and a
