46 THE ACRIDIIDAE OF MINNESOTA 
tegmina are long and surpass the abdomen, often as much as one 
fourth of their length. We have noted this species only at Fergus 
Falls, Granite Falls, and St. Paul Park. It is notably more solitary 
in habit than most of the members of this genus and in all cases men- 
tioned above but one specimen was taken, always amid the low scat- 
tered grasses of very dry soils. 
Hippiscus tigrinus Scudd. 
Dark brownish fuscous, of robust form and medium size. Head 
narrowed above and rugulose; fastigium of vertex distinct, with rather 
sharp, though not high bounding, walls, closed behind by a distinct, 
though slight, transverse, arcuate carina; lateral foveolae not deeply 
impressed, triangular; the median foveola, between their tips, slightly 
impressed ; frontal costa moderately broad, narrowed at the summit 
much more than below the ocellus, deeply sulcate at the ocellus, and 
plane at the considerably expanded base. Pronotum expanding con- 
siderably on the metazona, which is a little tumid centrally, the rugos- 
ities of the latter, which are considerable, ranged more or less dis- 
tinctly into series parallel to the sides of the process; median carina 
subobsolete or at least depressed between the sulci, distinctly arched 
on the metazona; lateral canthi distinct and sharp in the middle of the 
pronotum, a faint, rather ashen band next their inner side; posterior 
process of the metazona rectangulate. Tegmina ashen gray, brownish 
at the base, vitreous on the apical third or more, the transverse bars 
dark brownish fuscous, mostly crossing the wing, those of the apical 
half not at all rounded, with rare exceptions with ill-defined irregular 
margins, and extending, though fainter, to the tip of the wing; sutural 
line testaceous. Wing very pallid citrine at base, pellucid at tip, occa- 
sionally with one or two fuliginous cellular spots at tip, the veins and 
cross-veins blackish on apical portion, yellowish on basal, with a broad, 
subequal, arcuate, dark, fusco-fuliginous, median, scarcely tapering 
band, leaving four or five lobes free, separated by a yellow line from 
the humeral vitta, which extends from very nearly as far out to the 
base of the wing, the costal margin fusco-testaceous. Hind femora 
externally brownish fuscous with only obscure, if any darker, very 
oblique bars, dirty clay-yellow below, the under surface, like the tibiae 
and tarsi, luteous, the spines black-tipped. Length, female, 39 mm., 
tegmina 37 mm. 
The species is here included upon Lugger’s record (Third Ann. 
Rept. of Entomologist, Minn. Exp. Sta., 1897, p. 152) where he men- 
tions “two specimens” but gives no definite locality. We have seen 
but one specimen of this species, taken in northwestern Iowa by Ball
