212 ORTHOPTERA OF NOVA SCOTIA—PIERS. 
ments, make it very difficult to detect. Attention is chiefly 
directed to it by the loud stridulation of the males at nightfall. 
During the day they are usually silent, or at rare intervals 
produce a short, sharp note, zip. After dark, however, they 
make the swamps resound with their loud calls, and we then 
become aware of their abundance. On close examination at such 
a time, the males—usually only one on each bush—may be seen 
walking very slowly over the leaves and twigs. Occasionally 
they suddenly shghtly lft and part the wing-covers and close 
them again, thereby producing a sharp zip or crick, not very 
loud—this being the note which is usually heard during day- 
light. After making this sound at irregular intervals for some 
time, the wing-covers are opened to a greater extent, and are 
then again closed, producing a long-drawn, exceedingly loud 
er-r-r-r-r-r-r-ick, This is repeated in couplets several times in 
succession. This challenging cry is immediately answered by 
one after another of its neighbouring fellows, until numbers are 
rasping out their ear-piercing notes, as notable a rural chorus as 
that of the Tree Toads. Gradually the sounds become few, but 
after a short interval they are again frequent. This note is 
doubtless the loudest produced by any of the Orthoptera I have 
yet heard in the province. It can be partially produced by 
moving the wing-covers of a captive or dead individual. The 
note bears little or no resemblance to that of its famous relative, 
the broad-winged Katydid (Cyrtophyllus concavus) of the Cen- 
tral and Eastern States. Our species, as I have before observed, 
is usually very slothful. Occasionally, however, in daytime, 
and doubtless also at night, they fly some distance from tree to 
tree. One noted on September 28th, while it was attempting to 
cross a road, made only short flights, and usually fell on its 
side when it came to the ground. It, however, easily flew to 
and lighted upon a fence rail. Usually the insect can be readily 
captured with the fingers while it clings to a leaf. Occasionally, 
on a near approach to the bush upon which it rests, it will drop 
suddenly a foot or two to a branch beneath. I have not yet 
succeeded in detecting the female, although I have carefully
