In surface, sculpture of the head and thorax closely resembliug the species last men- 
tioned, but with the median carina of the pronotum more distinct, and a heavier pih» 
upon the head and thorax. Whole head below the lower level of the eyes varying 
from cinereous to chalky white, flecked on the posterior border and on the frontal 1 
costa with black specks; upper part of head dark cinereous, mottled with black, with 
a narrow black stripe behind the eye. Thorax cinereo-testaceous, with a large- 
central blackish spot on the disk, and a heavy quadrate black blotch over the front 
portion of the upper half or more of the deflected lobes, folldwed beneath by whitish. 
Tegmina cinereous, heavily flecked with blackish fuscous, especially collected on their 
basal half into two transverse bands, one in the middle and the other at the base of 
the second quarter; on the apical half the spots are quadrate and more or less clus- 
tered into short oblique bars. Wings varying from entirely dark fuliginous, with a 
faint hyaline cloud near the apex of the costal margin, to dark fuliginous, with the 
apical third hyaline but containing a few dusky flecks. The wing differs from that 
of the typical species in that the middle of the anal area is not so ample, aud that the- 
spurious veins lie closer to the branches of the anal vein and do not extend so far 
toward the base, this species approaching closer to Trimerotropw ; the cross-veins, 
also, are more distant aud not so distinctly scalariform, so that some of the character- 
istic features of Cirvotettix are here much weakened. Hind femora cinereous, with 
two transverse bands of black flecks; hind tibiae yellowish cinereous, blackish at ex- 
treme base, and infuseated beyond a basal yellow band. 
Length of body, 25 mm ; of tegmina, 25 m,n ; of wings, 22"""; breadth of same, 14 mm ; 
length of hind tibiae, 10 mm . 
A single male from the summit of the Sierra Nevada was given Dr. Packard by Mr. 
Henry Edwards. Baron Osten Sacken also gave me two males from the same place, 
taken between July 17 and 22. 
Trimerotropis i.atifasciata nov. sp. 
Brownish cinereous, the vertex darker than the rest of the head, all the sculpturing of 
the head sharply defined ; antennae yellowish brown, deepeuiug apically. Posterior 
half of anterior lobe of pronotum rather strongly corrugated, the median transverse 
sulcus very deeply impressed ; surface of anterior lobe otherwise smooth, posterior 
lobe delicately but distinctly rugulose ; median carina rather prominent and heavy on 
anterior lobe, slight but sharply defined and posteriorly obsolescent on posterior lobe. 
Tegmina marked with two obscure, narrow, transverse belts of dark fuscous flecks, 
one in tie middle aud one beyond the basal fourth ; a similar but faint third band 
appears before the base of the apical fourth, and beyond it a few obscure quadrate 
fuscous flecks in the diaphanous part of the tegmina, caused by the infumation of 
single cells and the nigrescence of their bordering veins. Wings very pale yellowish 
or milky, with a diaphanous tip, on which the veins are black and the cross-veins 
yellowish or partly yellowish and black, and with an unusually broad, very dark, 
almost piceous middle band, occupying about oue-third the length of the wing on the- 
middle of the costal margin, and curving around to the inner angle; its outer border 
straight or even slightly concave until, just before it reaches the outer margin, which 
it avoids by bending inwards a short distance; the inner border of the band is> 
strongly and pretty regularly arcuate, scarcely tending toward the base above. Hind, 
femora with faint traces of a pair of dusky transverse bands on the outer face ; hind 
tibiae pale reddish, with black-tipped spine. 
Length of body, 29 mm ; of antennae, 11.5 mm ; of pronotum, 6 mm ; of tegmina, 32 n,m ; 
of hind tibke. 12 mm .
