ORTHOPTERA OF NOVA SCOTIA—PIERS. Dai Wil 
Windsor, and it is probably as plentiful all over the province. 
Its notes are one of the most familiar sounds of autumn, and are 
heard both during the day and night. The stridulation is pro- 
duced by lifting the wing-covers about 45° above the abdomen 
and then shuffling them together, producing a sound resembling 
the word plee-e-e-e, plee-e-e-e, plee-e-e-e, or erce-e-e-e, etc. It has 
been suggested that these notes can be reproduced by taking a 
silver half-dollar between the fingers and striking the coin with 
the edge of a nickle. These autumnal sounds ring continually 
in our ears until the first frosts put a stop to the love-making. 
During recent years the shrilling of this species has been first 
noted on the following dates: August 19th, 1890; August 6th, 
1891; July 29th, 1892 (at Windsor, N.8S.); August 2nd, 1893 ; 
July 29th, 1895; August lith, 1896. By October 31st of last 
year, only two or three individuals could be heard, and by 
November 6th, a lovely, warm, Indian summer day, on listening 
at one place, only about one individual could be detected—in 
fact the species was all but silent. None were noted after that 
date, although a few individuals might have been found two or 
three days later. 
I have not observed the form fasciatus in Nova Scotia. 
Scudderia pistillata, Brunner. 
The general colour of this insect, as found in Nova Scotia, is 
a pale oil-green or apple-green; upper part of eye, brown ; 
region between base of antennz, centre of face, and labium, 
white; a cream-buff stripe on each dorso-lateral part of the 
thorax ; beneath, whitish-green; white between the legs and on 
the throat, and two longitudinal white lines, slightly raised, on 
the ventral surface of the abdomen; soles of feet and antenne 
light brownish. Length of head and body, exclusive of abdo- 
minal appendages, 22 mm. 
This handsome Katydid is very common about Halifax. It 
is found upon the foliage of bushes, chiefly alders, in or near 
swampy places. Although so plentiful, yet its protective simili- 
tude to a leaf, both in colour and form, and its usual slow move-
