General! direction how to collect and prepare diptera ; 
principal points are, the middle dorsal line must remain 
perfect, diptera must not be killed with alcohol, killing 
with potassic cyanide [KCN] not recommended, very 
small diptera should not be killed when they cannot be 
pinned immediately, too much material should not be 
collected in the net at one time, hairy diptera (such as 
bombylidae) should not be taken in the hand to pin, 
lacquered iron needles or lacquered iron wire to be used 
for pinning instead of common pins or silver wire 
(which contain copper, and are therefore liable to cor- 
rode), never use too large pins, use wire for all diptera 
under 3 mm. long, never pin in an unpaired part of an 
insect, never pin minute diptera in the dorsal side, but 
pin them in the mesosternum between the middle and 
hind thigh of the left side, diptera should not be glued 
upon paper or imbedded in resin, and should not have 
their wings spread; hints on labelling diptera, on pin- 
ning them in boxes, and on packing them to send; 
descriptions of different apparatus convenient in col- 
lecting diptera. G: D. (2335)
