MORSE: ORTHOPTERA OF NEW ENGLAND. 351 
Antennae nearly twice the length of the body, tapering gradually, 
greenish. Pronotum broad, short, rugose, with two conspicuous 
transverse grooves and upturned dorsal hind margin, without 
noticeable lateral carinae. Front and middle legs of moderate 
length, hind legs short and relatively weak, the creature traveling 
chiefly by crawling rather than leaping, Subgenital plate of 
male greatly elongated into a narrow, grooved, tongue-like organ, 
shghtly upcurved, shallowly excavate above, with an acute, 
slightly bifurcate tip. Cerci of male grapple-like, consisting of 
two narrow prongs from a broad base, the upper lying above the 
subgenital plate, curved and tapering to a delicate upturned 
black tip, the lower and stouter of the two projecting downward 
and bent abruptly inward, terminating in a strong black-tipped 
point lying beneath the subgenital plate. Ovipositor four to 
five times as long as wide, scimitar-like, curving gently upward to 
an acutely pointed, finely serrulate tip. 
The color is a rather dull leaf green, darker on the tegmina, 
paler on the legs, and nearly white beneath, the stridulatory area 
of the male brownish purple. The colors of the fresh insect 
change to a dull yellowish or brownish green after death.

This insect is the Katydid of song and story, so named from its 
peculiar stridulating cry, which consists of from two to four 
syllables of most raucous quality, variously translated by its 
hearers into Katy, Katy-did, she did, Katy-she-did. Primarily 
a mating call to allure the female to the proximity of the male, it 
is also used by him defensively. A captured male in my posses- 
sion, when approached closely by the hand, would promptly 
elevate his wing-covers and sound the hoarse, rasping cry, a 
proceeding the effect of which upon an attacking bird may 
readily be imagined. When actually seized these insects also use 
the powerful jaws to inflict a severe pinching bite upon incau- 
tious fingers. 
The note is one of the loudest made by New England Locus- 
tarians and may be heard, under favorable conditions, at a
