S. orthodox , another synonym of S. piger, for specimens from Logan 
Canyon, Cache County, Utah. Attems (1931) described S. pallidus, 
a synonym of S. bergrothi, from Mukilteo, Snohomish County, Wash- 
ington, and S. insulanus from Nanaimo, Vancouver Island, British 
Columbia. Chamberlin (1941) described S. simplex from Days Creek, 
Douglas County, Oregon. 
The remaining papers covering western forms of Scytonotus 
either provided new records or summarized existing ones. Attems 
(1940) reviewed all the congeners, from both the east and west, 
transferring amandus into Archipolydesmus . Chamberlin (1943) trans- 
ferred amandus into Scytonotus and recorded it from Georgetown, 
Bear Lake County, Idaho, the first record of the genus from this 
state. Causey (1954a, b) recorded S. amandus from Teton County, 
Wyoming; S. pallidus from Seattle, Washington; and female and 
immature specimens, identified only as Scytonotus sp., from five 
additional counties, one in eastern Washington. Chamberlin and Hoff- 
man (1958) summarized all the species in their Nearctic checklist, 
placing S. palidus in synonymy under S. bergrothi. Hoffman (1962b) 
estimated that about seven species occurred from northern California 
and Utah to British Columbia and Alaska; he (Hoffman 1979) re- 
peated this estimate and characterized the western range as the Rocky 
Mountains and west coast states. Loomis and Schmitt (1971) re- 
corded Scytonotus from Montana, citing S. amandus from Lincoln 
and Mineral counties. Kevan (1983) listed all the species that were 
known from, or probable for, Canada, both in the east and west, 
and Shelley (1990) summarized the generic range in British Colum- 
bia and Alaska, giving the type localities of species in the former 
and misspelling insulanus and insulans. 
Thus at this writing, Scytonotus consists of the following spe- 
cies, listed chronologically below with their type localities and other 
reported occurrences: 
S. granulatus (Say 1821). Vicinity of Philadelphia, Pennsylvania. 
Also recorded from Canada in general (Wood (1865), Ontario (Causey 
1952, Hoffman 1962b, Judd 1967, Kevan 1983, Shelley 1988), and 
the following states: New York (Cook and Cook 1894, Bailey 1928, 
Chamberlin and Hoffman 1958, Hoffman 1962b, Kevan 1983), Penn- 
sylvania (Gervais 1847; Koch 1847, 1863; Wood 1865; Cook and 
Cook 1894; Dearolf 1938; Loomis 1939; Attems 1940; Chamberlin 
1947, Chamberlin and Hoffman 1958; Hoffman 1962b; Kevan 1983), 
Maryland (Hoffman 1962b), District of Columbia (Cook and Cook 
1894), West Virginia (Hoffman 1962b), Virginia (Cook and Cook 
1894; Hoffman 1947, 1950a, 1962b), North Carolina (Brimley 1938; 
Chamberlin 1940; Hoffman 1950b, 1962b; Chamberlin and Hoffman
