have come from New England or was it a case of accidental mis- 
labeling? There the matter rested until Miss Fogg, studying the 
Orthoptera of the vicinity of Manchester, N. H., captured two 
or three specimens of a short-winged Locust which she identified 
and recorded as M. scudderi but which on examination proved to 
be M. dawsoni. Since then I have taken it personally at both 
localities. 
I found it in grass (timothy, bunch-grass, etc.) on sandy soil, 
in near proximity to low open woods of pitch pine with scrubby 
undergrowth. Though common in Minnesota and the West, in 
New England it evidently occurs only as a very scarce and local 
species whose presence will be detected only by good luck or 
extreme persistence and thoroughness in collecting. The New 
England specimens were taken in August and September. In 
Minnesota it is mature in July and August and disappears shortly 
after September first.

Size small ( cf ) to medium ( 9 ) . Head moderately large and 
eyes rather prominent in male. Prosternal spine of female 
conical from a broad base and bluntly rounded at tip, in the 
male cylindro-conic. Tegmina much abbreviated, broadly and 
bluntly lanceolate (cf) to subovate (9), about three-fourths as 
long as pronotum, attingent or sub-attingent dorsally. Hind 
femora of moderate size and graceful form. Subgenital plate 
of male in side view triangular, the sides straight or nearly so, 
the dorsal margin but sHghtly shorter than the ventral, often a 
little concave, the apex acute, rounded at tip; from above, the 
sides straight, tapering to a bluntly rounded point. Cerci 
rather long, equaUing supra-anal plate, twice as long as width of 
base, narrowed rapidly on dorsal margin of basal third or half to 
half the width of base, the distal half or third equal, with sides
