The Round-winged Katydid is our smallest and most common 
species of the genus. It is frequently captured by sweeping the 
net over low-growing shrubs and dense grass in moist fields near 
shrubbery. It matures in late July or in August and may be 
found throughout September. It is recorded from eastern Mass- 
achusetts, Connecticut, southern Vermont, and extends, in three 
closely related races, to North Carolina, Texas, and Iowa. 
Scudder remarks that "it stridulates both by day and by night 
and without variation. The song consists of from two to four 
syllables . . . sounding like chic-a-chee, repeated rapidly so 
as to be almost confounded, and when three requiring just one- 
third of a second. The song is repeated at will, generally about 
once in five seconds, for an indefinite length of time." 
THE BUSH-KATYDIDS; NARROW- WINGED KATYDIDS— 
SCUDDERIA. 
New England is the home of several species of Katydid-like 
insects distinguished by the possession of certain peculiar char- 
acters which unite them into a single genus, named in honor 
of our most prominent resident student of the Orthoptera, 
Scudderia. 
They are large yellowish-green insects with strongly compressed 
body, vertical wing-covers, and slender antennae of moderate 
length. In sharp contrast to the Round-headed Katydids, the 
vertex of the head in these insects is strongly narrowed between 
the antennae and acuminate at apex. The females have a short, 
broad, strongly compressed and upcurved ovipositor, and resem- 
ble each other closely. The form of the terminal segments of the 
male abdomen is peculiar and characteristic of each species: in 
general, the subgenital plate is greatly extended into a long, 
upcurved process, broad and depressed at base, narrow and
