cited an illustration by Ross (1938, fig. 48) as an example. It is not 
clear what basis there was for this character; no reference was made 
to it in Ulmer’s original description (no genitalic preparations had 
been made from the type series), and Ross’ figure actually shows a 
third small apical spine on the paramere. Origin of the specimen on 
which Ross’ figure 48 was based was not given, although Banks 
(1943: 364) stated that it came from Inyo Co., California; further- 
more, although designated as O. unicolor by Ross, the specimen was 
not accepted by Banks as the male of that species (see above), evi- 
dently because he regarded it as O. coloradensis. 
We have examined the three co-types (2<5, 1?, S. Colorado, 1879) 
in the collection of the Naturhistorisches Museum, Vienna. The 
parameres of one male each have three spines and those of the other, 
four spines. We find no other features of these males that are dis- 
tinctive. In the female of the type series, the apical lobes of segment 
X are rather long and slender, lacking the basal ledge or tooth of the 
holotype of O. unicolor or the females in the type series of O. tristis. 
The two corneous points in the fore wing are dark in all specimens, 
which in the males particularly are surrounded by a relatively large 
dark area. 
O. quadrinotatus (Banks). We examined the holotype male 
(Grand Lake, Newfoundland, 28 July 1906) in the Museum of 
Comparative Zoology. This is the only name based on material 
from eastern North America, and was distinguished from the west- 
ern forms by uniformly dark fore wings (Banks 1943). The holotype 
displays this character, but in some eastern populations there is a 
tendency for slighty darkening around the spot in cell R4 (Fig. lb). 
Moreover, some specimens from western North America also have 
uniformly dark fore wings, e.g. Fig. Id. Some of these have several 
spines on the parameres (e.g., California, Nevada Co., Sage- 
hen Cr., 4 Aug. 1985, 1(5, ROM), but in others the spines are 
reduced to one or two (Utah, Summit Co., E. Fork Bear R., ca. 2 
mi. above confluence with Bear R., 4-5 Aug. 1985, 7 $, ROM; 
Idaho, Teton Co., Darby Cr., 6-7 Aug. 1985, 6(5, ROM). The holo- 
type male has five and six spines respectively on the two parameres, 
distinguished by the basal spine being little longer than the others 
and not reaching the tip of the paramere (Banks 1943). Within the 
eastern part of North America where no western species has ever 
been recorded in the literature, we found spines of the parameres
