MORSE: ORTIIOPTERA OF NEW ENGLAND. 463 
acfute, disk tuberculate and granulate; prozone tuberculate but 
not rugose, convex. Lateral lobes as long as deep. 
Pale brown or yellowisli clay color, more or less infuscated 
above. Pronotum often bearing a pale X-mark on disk. Teg- 
mina with dorsal field usually pale, more or less infuscated at 
base except on edge between it and lateral field. A pale streak on 
basal half of costal vein, interrupted by a dusky spot behind the 
marginal angulation; another on the intercalaiy vein, broadening 
to cover a large part of the distal discoidal field where it is macu- 
late with dark brown, leaving the ulnar area immaculate dark 
brown or fuscous. Wing with disk bright coral-pink bordered by 
a narrow dark-brown band which reaches from anal angle to 
costal margin, usually discontinuous between anal and humeral 
fields and sending off a subfrontal shoot which reaches to the 
base; beyond this the wing is transparent with dusky veins and 
smoky tip in the male. Hind femora usually obliquely fasciate 
with dusky. Hind tibiae dull yellowish or pinkish, the spines 
tipped with black. 
Yellow-winged examples of this species have been taken but are 
of very rare occurrence. Sometimes the head, pronotum, and 
hind femora, even in the half-grown nymph, are largely green.

Ramblers in the fields of June are often stirred by the sight of 
flashing pink wings in rapid flight, which vanish suddenly, and the 
less observant or reflective ask the identity of a "beautiful pink- 
winged butterfly" which disappeared as mysteriously as it came. 
This is it. Its gaily colored wings make it a conspicuous object in 
flight, and it is very ready to take wing and goes to a considerable 
distance. The female is much less active than the male and sel- 
dom rises more than once, even when pursued. The flight of the 
male is often accompanied by a rapid rattle, louder than but sim- 
ilar to that of the Spring Yellow-winged Locust (Arphia sulphurea) 
with which it is commonly found associated. Its haunts are 
upland pastures, abandoned fields and unimproved lands, often 
partly overgrown with weeds and bushes, where it is found from 
the last week of April till mid-July, or even later.
