68 THE ACRIDIIDAE OF MINNESOTA 
aerial stridulation of some of the Oedipods, but much less audible. 
The species matures during July and is present until severe weather in 
the fall. In the southern states this species, together with the follow- 
ing, may be seen active throughout the winter. We have seen both in 
the woodlands of South Carolina, feeding and flying when alarmed 
even during January. 
Schistocerca americana Dru. 
We have not taken Schistocerca americana within our area as yet, 
although we have taken it at Rock Rapids, Estherville, and other 
points in the extreme northern part of Iowa and feel no doubt that it 
will be found at least occasionally in southern Minnesota. It is a fine 
large insect, more reddish in tint and more heavily maculate than either 
of the foregoing. It is very difficult to capture during the bright warm 
days of summer but in late autumn it becomes sluggish, feeding little 
and hanging motionless to the sides of buildings or other elevated 
places, evidently enjoying the warmth of the sun’s rays and awaiting 
the end, although as just stated it and others of the genus remain 
active throughout the winter in the southern states. We have heard 
the children call this insect the “bird grasshopper” and truly, when 
seen in flight, its great expanse of wing makes this name very fitting. 
Scarcely less apt is the name “‘clickety bug” given it by the negroes in 
South Carolina, referring to the rustling of its wings in flight. 
HY POCHLORAY Brann. 
Body rather slender, compressed, and sparingly pilose. Head not 
prominent, the summit gently arched, the fastigium moderately dec- 
livent; interspace between the eyes broad, frontal costa rather nar- 
row, sulcate, percurrent, and subequal. Eyes not very prominent, 
similar in both sexes; antennae moderately stout and about as long as 
the head and pronotum. Pronotum subequal, very feebly and grad- 
ually enlarged posteriorly, with a distinct percurrent median carina; 
the disk very broadly subtectate with the lateral carinae not well 
marked. Lateral lobes of pronotum vertical. Front margin of prozona 
subtruncate, hind margin of metazona very obtusely angulate; the very 
coarsely, feebly, and sparsely punctate prozona half as long again as 
the very finely and suddenly punctate metazona, its posterior margin 
faintly angularly emarginate; one transverse sulcus dividing the disk 
into equal halves, and straight, the other a third of the distance behind 
this and sinuate. Prosternal spine erect, moderately slender, and coni- 
cal. Mesosternal interspace much longer than broad in both sexes,
