28 THE ACRIDIIDAE OF MINNESOTA 
insect were accidental in sweeping, and in every case it has been taken 
from Carices. We have taken it at Fergus Falls, Lake Winnibigoshish, 
Allen Junction, and near the upper end of Vermillion Lake. 
Mecostethus platypterus Scudd. 
Mecostethus platypterus is about the size of M. lineatus, but with 
the wings relatively shorter. The coloration is of a dull brown with 
the dorsal field of the tegmina grayish and with no pale stripe along 
the scapular area. The figure gives a good idea as to the general 
appearance of this insect, although the relative length of the prozona 
is apparently exaggerated. The drawing, however, is accurate and 
correct and the suture passes but little behind the middle. We have 
taken this insect only in the dense tangles of tamarack swamps near 
Mesaba and at Allen Junction. At these places the immature stages 
were not at all rare on July 25, but there were relatively few adults. 
The species has been reported outside the New England States but 
rarely; Hart (Bull. Ill. State Lab. Nat. Hist., VII, p. 205) mentioned 
it from Illinois, and there is a specimen taken at Little Rock, Iowa, in 
the collections of Iowa State College at Ames. 
STENOBOTHRUS., Fisch. 
Stenobothrus, as now recognized, is largely western in distribu- 
tion and is made up of insects of small size and varying coloration. 
The vertex is broadly triangular in both sexes, more obtuse anteriorly 
in the females. The foveolae are narrow rectangular or almost linear 
depressions, rather deep, and plainly visible from above ; median carina 
wanting or sometimes indicated by a lighter line; face quite oblique 
though rounded at the vertex; head somewhat elevated above the 
plane of the pronotum. Pronotum rather short, the anterior margin 
truncate, the posterior broadly subangulate in males, sometimes almost 
rounded in females; the median carina is distinct and cut somewhat 
behind the middle by but one sulcus; the lateral carinae are, in all our 
forms, somewhat incurved before the middle. The tegmina are fully 
developed although varying or dimorphic in length. The posterior 
femora are somewhat mottled but rarely distinctly spotted; posterior 
tibiae testaceous or, rarely, red. As now known we have but one 
species within our limits. 
Stenobothrus curtipennis Harr. 
Stenobothrus curtipennis is a small insect, which in Minnesota is
