Numerous localities. 
Bradynotes opimus nov. sp. 
Closely allied to D. obesux ( Pezotettix obesus Thom. ) General color blackish griseous, 
more or less flecked with brown ; face and genae below the eyes varying frdm pale to 
pinkish livid, punctate, especially below, with black, and divided by black stripes 
following the edges of the frontal costa and the lateral carinae of the face, and also, 
generally, the arcuate posterior carinae of the genae, and an oblique line of punctures 
subparallel to it below the middle of the genae; summit of head with a median and 
a pair of arcuate, lateral, narrow black stripes, the former the darker; antennae testa- 
ceous near the base, blackish beyond. Anterior lobe of prouotum with a large central 
blackish spot, inclosing a pair of testaceous dots, laterally disposed ; lateral lobes 
lighter below than above, speckled, with a broad, somewhat broken, black median 
band crossing the anterior lobe ; tegmina wholly wanting. Abdomen varying from 
grizzly to blackish, the posterior edges of the segments dotted with minute longitudinal 
spots, and some of the posterior segments marked with a central, triangular, testaceous 
spot, seated on the posterior border. Hind femora with the outer face generally 
altogether black, occasionally lighter and marked with a central, oblique, pale dash 
above; upper and lower faces pale testaceous, the inner side of upper face with a 
pair of black bars ; hind tibiae deep purplish at base (with the basal outer tubercle 
deep red), passing into deep red beyond the middle, the under surface clay -yellow ; 
the spines on basal half pale, on apical half reddish, all black tipped. Anal cerci 
nearly straight, subcompressed, but convex exteriorly, broad at base, tapering through- 
out more rapidly on the basal than on the apical half to a bluntly-pointed tip. 
Length of bodv, <? 23 !nm , 9 24 mm ; of antennae, <J 9.5 mra , 9 i0.5 mm ; of prouotum, 
$ 5.5 mm , 9 5 m ™; of hind tibiae, $ 9 10.5 mm . 
This species differs from B. obenw in some of its markings, in the lighter punc- 
tuation of the posterior lobe of the prouotum, aud especially in the anal cerci of the 
male, which are much stouter and coarser, not so strikingly divided into a rounded 
basal and slender, almost linear, apical half, as in B. obeaus. Like it, it comes from 
high elevations. Baron Osten Sacken brought home specimens taken in the Sierra Ne- 
vada between July 17-22, some of them immature ; and Dr. Packard took 1 ^ 2 J at 
the forest line on Mount Shasta, Cal. A single specimen, damaged by too long pres- 
ervation in alcohol, and brought by Mr. W. G. W. Harford from Oregon City, appears 
to belong here.
