NEW ACRIDIIDAE FR(JM THE SOUTHERN STATES. 
BY .YLBERT P. MORSE, WELLE.SLEY, MA.SS. 
Sever.yl previously unnoted members of this family were taken in the summer 
of 1905 during a second trip in the South under the auspices of the Carnegie Insti- 
tution of Washington. 
Nomotettix cristatus denticulatus var. uov. 
This variety, for it is unlikely to he more than that, is more scabrous than the 
type form, with the margins of the pronotum very minutely serrulate, sides of the 
vertex of the headless regularly convex, its carina less protuberant, the carina of the 
pronotum thinner and higher, the middle femora with undulate margins, and the 
upper edges of the hind femora usually with inwardly or upwardly directed den- 
ticulate processes. 
Six males, one female; Caddo, Haileyville, So. Mc.\lester, I. T.; Denison, Tex. 
Aug. 6 to 1.3. 
Hippiscus immaculatus sp. nov. 
The specimen under consideration is the size of II. rugo.'tus. The pronotum is 
less rugose, smoother in outline and in surface, a little narrower; the hind margin 
slightly obtuse-angulate, its sides straight and its apex rounded. Wings like those 
of rugo.iu,t, the tip infuscated l)ut not maculate. Ground-color of tegmina a pale, 
almost vinaceous, brown; the basal half of the anal field suffused with fuscous e.xcept 
along the anal vein; the distal half of the costal field more or less suffused and the 
basal third finely maculate, the proximal part of the discoidal field evenly suffu.sed, 
the veins and venules of the distal part more or less infuscated apically, and a slight 
fuscous suffusion near the base. 
Compared with rugo,‘ms the specimen differs relatively little structurally or in 
wing-marking, but radically iu the tegminal pattern which suggests that of tuber- 
culatus but is much less distinct. 
One male. Clarendon, Tex., Aug. IS.
