The Night.—The uncertainty of the result of using indoor 
light must be plain to those who have tried it. It is quite 
impossible to foretell a good night. Great results will only occur 
occasionally, and to those who use perseverance with their oil. 
On warm, dark, quiet nights, the greater the chance, but often 
such nights are a failure. Again, excellent results are frequently 
obtained on a moonlight night, darkened occasionally by passing 
clouds; dark nights with warm summer rain are good, and even 
with heavy rain, particularly after a drought. The slightest frost 
renders light useless. Hill-mists sometimes are good, but fogs 
are bad. Wind is the greatest enemy of light; however favourable 
in all other respects, anything like wind renders the attempt 
hopeless. Besides Lepidoptera, many orders of insects are 
represented on a good night at light, and it is most interesting to 
note the time of arrival of the various species, as well as their 
behaviour in the room. Sphinges fly up and down the walls. 
Most of the Bombyces, Noctue, and large Geometre dash past 
the light and circle round and round the ceiling. Some Noctue 
settle at once anywhere; others seek concealment by hiding 
behind pictures, shutters, &. The smaller Geometre fly round 
about the lights; while the Pyralides, Crambi, Tortrices, and 
Tine settle on the lamps, or where the light is thrown on the 
table, walls, or window. Some species rarely enter the windows, 
but fly up to the light and depart again; these I have had to net 
by means of a ladder outside. If the walls of the house and 
crevices of the windows are examined next day, some of the last 
night's visitors are usually to be found there at rest. Bats hawk 
backwards and forwards in front of the window, destroying no 
doubt many a prize. There is a vast amount of pleasure and 
excitement, as well as knowledge, to be derived from a first-rate 
night at indoor light. I well remember persuading a non-collector 
to try it one night in the country, and he reluctantly accepted the 
invitation. Within a short time of commencing operations, his 
pipe was thrown down, and he was rushing wildly about, with his 
coat off, netting moths, and, remaining until daylight, he proved 
himself to be an invaluable auxiliary.
