Morse ('04, p. 16) states that this species has a preference for 

 "wet meadows and swales." 



Tcttigidca parvipcnnis Morse. Short-winged Grouse Locust. 



A single specimen was secured in the upland forest (Sta. IV^, a) 

 on dry leaves Aug. 22 (No. 122). 



Hancock ('02, p. 149) found this species very abundant in moist, 

 dense woods. 



Dichronwrpha viridis Scudd. Short-winged Grasshopper. (PI. LVII, 



fig. 7-) 



A green short-winged female was taken from the tall prairie 

 grass (Andropogon and Sporoholiis) colony (Sta. I, ^) Aug. 12 

 (No. 39). The following were taken from the upland forest (Sta. 

 IV, a) : Aug. 16 (No. 67) on dry leaves, a nymph, a long-winged 

 male, and three short-winged females; Aug. 17 (No. 92) in an open 

 space, a copulating pair, both of which were brown and short-winged, 

 and a brown short-winged female (No. 93) ; Aug. 22 two more cop- 

 ulating pairs, one (No. 121) brow^n short-winged forms, the other 

 (No. 122) green short-winged individuals. In a glade in the low- 

 land forest where grasses, Bupatoriuin civlcstinuin, and young sas- 

 safras abounded (Sta. IV, c), a nymph, a brown short-winged fe- 

 male, and three males, two brown and one green, were taken Aug. 

 20 (No. 117), and on Aug. 22 a green female nymph and green and 

 brown short-winged males (No. 143) ; and on the slopes of the valley 

 (Sta. I\", b) a green short-winged female was secured Aug. 20 

 (No. no). 



On account of the disparity in the size of the sexes — the males 

 being much smaller than the females — it is possible for copulating 

 females to jump about and carry the males with them, the pair No. 

 121 affording an example. 



According to Morse ('04, p. 19, 32) this is a forest and thicket 

 species which also frequents "tangled herbaceous growths whenever 

 found." In New England it frequents "grass fields on wet soil, near 

 the margins of ponds and streams ; in the Sovith and Central States 

 it is more commonly found in rank herbage along ditches and streams, 

 and in the edge of moist woodlands. Its haunts are thus intermediate 

 in character between those of a campestral and sylvan species, and 

 so likewise are the structural adaptations presented by it, a verv large 

 proportion of the females being brachypterous." 



It will be noted that the Charleston series is mainlv from the 

 forest area, only one individual coming from the true (moist) prairie; 

 also that the forest, even the upland part, is in close proximity to a
