In oculatum the pubescence of tlie hind femoni seems to be more 
higlily developed tlmn in scudderi, but iiidiYiduais vary mucli. 
The COLOR of the body as a whole is very simihir, hut oculatum 
has more of a yellowish cast, while in scudderi reddish or rusty 
predominates. This difference, liowever, is doubtless due 
merely to tlie character of its liaunts. 
4. — 5'. saxaMle vs. S. bolli. 
In saxatile tlie head is larger and less compressed ; the eyes 
are slightly larger and distinctly more prominent ; the vertex 
broader, less acute, less advanced and more declivept; the face 
more nearly vertical and more rounded in profile at meeting with 
vertex. 
In saxatile the pronotum is less compressed ])Osteriorly, the 
disk is less angulate on the anterior margin, broader on the meta- 
zona, the apex of posterior process less sharply pointed. In saxa- 
tile the DISK is less flattened ; ai'ched mesially in median section 
on the metazona, and on hinder half of prozona sloping up to 
form the carina. The carina is scarcely as high, much lower on 
posterior half of metazona, unequally and less developed through- 
out ; while in bolli it is equally developed, rising sharply from 
the flat disk. This is more noticeable in J* tlmn in 9. 
In saxatile the incision of the principal sulcus is dee[)er, and 
the notch open instead of nearly or quite closed. 
In saxatile the maculations of the tegmina have sharper out- 
lines and contrast more with the ground color. The wings are 
more vividly colored, the fuscous band blacker and more sharply 
defined, reaching the anal angle, while in bolli it fades out some 
distance short of that point. In saxatile the subfrontal shoot is 
longer, reaching about halfway to base of wing ; in bolli about 
one third to base. The apical fuscous ])ortion is either maculose 
or fumose and frequently connected to transverse band ; in bolli 
usually fumose and very rarely connected to band. In saxatile 
the lateral and antero-posterior dimensions of the yellow disk of 
the extended wing are about equal ; in bolli the antero-posterior 
exceeds the lateral. 
The HIND femora do not differ markedly, the i)roximal two 
fuscous bands on the inney side are perhaps more completely 
connected in bolli than in .saxatile, but considerable variation 
occurs. 
In saxatile the hind tibiae, while often showing some slight
