OF WASHINGTON. 125 
tumid in the male, the hind femora brownish with faint scalariform mark- 
ings on the outer face, the inner face somewhat infuscated and the geni- 
culations darkened; hind tibiae, in dried specimens, brownish or yellowish 
brown, the spines black-tipped, eleven to thirteen in outer series. Abdo- 
men reddish brown with a lateral black stripe along the upper portion 
of the sides, in the male extending quite to the tip, in the female scarcely 
beyond the basal half. Tip of the male abdomen neither swollen nor 
recurved, subgenital plate noticeably narrower than long, apically form- 
ing a blunt tubercle; supraanal plate elongate-triangular, the sides 
straight, median sulcus broad, deep, extending across the basal half 
of the plate; furcula small, short blunt teeth overlying the submedian 
ridges of the supraanal plate; last dorsal segment of the abdomen, just 
outside of the furcula, diagonally sulcate as in the aridus series. Cerci 
of the male very slightly compressed and moderately incurved substyli- 
form appendages tapering considerably and quite uniformly on the 
basal three-fourths, the tip more gradually tapering to a moderately sharp 
point. 
Length, male, 13 mm., female, 15 mm.; elytra, male, 2 mm., female, 
2.5 mm.; hind femora, male, 8 mm., female, 8.5 mm. 
Type. No. 8386, U. S. National Museum. 
One male, one female, Glenellen, Sonoma County, Califor-

Scudder's table of the puer series, page 128 of his Revision 
of the Melanopli, may be modified for the reception of this 
species as follows : 
f 1 Tegmina attingent; subgenital plate of male short and 
broad, its apical breadth surpassing the length of its lateral 
margins, not elevated apically flabellatus. 
f 2 Tegmina distant; subgenital plate of male distinctly nar- 
rower than long, elevated apically. 
g 1 Pronotum of both sexes truncate posteriorly, dis- 
tinctly emarginate mesially; interspace between the 
mesosternal lobes slightly longer than broad, male, 
or quadrate, female; metasternal lobes subattingent 
in the male; elytra widely separated, puer. 
g 2 Pronotum obtuse-angulate, at least in the male, not 
emarginate mesially; interspace between mesosternal 
lobes quadrate, male, or transverse, female; metas- 
ternal lobes distinctly separated in the male; elytra 
not widely separated sonomaensis. 
Trimerotropis titusi n. sp. 
A small species belonging to the mnculata group and falling next to 
Bruner's inconspicua but is in no way allied to it. 
General color light brown with the elytra banded conspicuously. Head 
prominent, in the male noticeably elevated above the pronotum and
