has tegmina and wings abbreviate, and agrees well with Rehn's 

 description^ of sk'umcri, described from southern Arizona, and 

 since reported from Texas, New Mexico, California, Colo- 

 rado, and Nebraska. However, as Caudell^ has suggested, it 

 is possible that males of other species of Litaneutria may 

 sometimes be brachypterous, and that of L. horealis Scudder 

 (described^*^ very briefly from Nebraska and also known from 

 Colorado) is unknown, so that there is some doubt about the 

 correct determination of these specimens. 



Phasmidae 

 Diaphcromcra fcmorata (Say). — Grand Forks, Grand Forks 

 County, summer 1892 (A. H. Eastgate), i male. 



Taken on shrubbery growing on the bank of the Red River. 



ACRIDIDAE 

 ACRYDIINAE 



Acrydium granulatum Kirby. — Stump Lake, July 24, 1920, 

 I female; Lake Upsilon, Turtle Mountains, Aug. 4, 1920, 2 

 juveniles; Fargo, Aug. 31, 1920, i juvenile. 



A single female was taken at Stump Lake near the edge 

 of a spring on a wet, mucky hillside among clumps of bushes 

 and tall shrubbery ; several nymphs were swept from the 

 grassy borders of the small stream flowing away from the 

 spring. Nymphs of several instars of this species were very 

 common on the gravelly beach of Lake Upsilon, among the 

 thin growth of grasses and low herbaceous plants, and espe- 

 cially among the patches of moss which cover parts of the 

 upper beach in places. At Fargo a single nymph was taken 

 on a mass of dead, matted grass near the muddy margin of 

 the Bois-de-Sioux River.
