MORSE: ORTHOPTERA OF NEW ENGLAND. 279 
pinned through one side of the posterior part of the pronotum 
(nietazone) — if properly done, this supports the wliole body per- 
fectly and allows the wings of tlie opposite sitle to he spread 
without difficulty. It was Scudder's custom to pin through the 
right side of the metazone and spread the wings of the left side. 
For spreading, the usual board with a deep, cork-bottomed 
groove is best, on account of the space required for the legs and the 
frequently crested form of the pronotum. After properly pinning 
in the groove and arranging the legs, bring the wings forward con- 
siderably more than a right angle, until the hind wing is fully 
expanded. Hold in place with strips of glass or cardboard until 
dry. For this work the glass-headed black pins sold as 'mourn- 
ing-pins' are desirable, and strips of window-glass or microscope 
slides with ground edges. It is usually necessary to spread the 
wings of but few^ of a kind, temporarily at least. 
At this time also, suitable arrangement of the legs, abdomen, 
and those parts of the body used in identification should be made 
if possible. In general, long antennae should be directed back- 
w^ard (but not too high nor too close to the pin) to save space, the 
parts of the legs slightly separated, and the end of the abdomen 
exposed to view to facilitate study. 
Dampened specimens may be removed from the setting-board 
in 24 to 48 hours; fresh, unstuffed specimens require 10 to 20 
days according to condition of the atmosphere, weather, etc. 
Labels, for convenience in handling and study, should be as 
small as possible but should give the essentials of place and date 
(State, town, day, month, year) and if more is desirable a 'lot' 
label may be used, with reference made to a lot-book in which 
are entered the full history and all details known. 
Collections, Cases. 
Collections of Orthoptera seem to be especially subject to the 
attacks of mold and insect pests. For these reasons they should 
be kept in a dry atmosphere, preferably above the ground floor, 
and always more than a foot above the floor of the room, the 
cases charged with naphthalin, and examined frequently. If 
found to be infested, fumigate, label, and inspect frequently for 
two years. Fumigation should be done at a temperature of 70° 
to 90° F., if possible, and with carbon bisulphide at the rate of
