Hah. Baltimore. Late in August, among the grass. 
This species has not yet been met with in any abundance here. The 
wing-covers are comparatively narrow, the costal margin a little dilated 
near the base; the surface against the thick nervure bounding the 
discoidal field posteriorly is sometimes tinged with a streak of rosy 
almost throughout its entire length. The colors are taken for the most 
part from a fresh specimen not immersed in alcohol. 
PEZOTETTIX, Burrn. 
P. Scudderi. 
Ferrugineo-fiiscous, form and general appearance of CaloptenuH fe- 
mur-ruhrum^ De G-eer. The cranium is, however, less prominent, the 
thorax slightly broader, and in the 9 black spot on the sides, just 
below the dorsal surface, is much narrower, sometimes entirely obsolete, 
the whitish spots upon the middle of the sides are indistinct and some¬ 
times entirely obsolete; the wing-covers do not reach much beyond the 
apex of the second segment of the abdomen, the under side of the pos¬ 
terior femur is yellow, and the tibiae have a black dot upon the knee 
and a black ring just below it; the apical tip of the last segment % is 
more narrowed, acute, and conically produced than in C. femur-ruhrnm.. 
In its other characters it agrees with that species. 
Length % 1(5—17, 9 22—23 millims. 
Hah. Baltimore; upon the sides of high hills. Rock Island, Ill.. 
(Walsh.) 
It is found in great profusion during the latter part of October. It 
is a completely developed insect, for I have taken many pairs in coitu.
