Saturniidae 
dark of which I have been speaking. Some of the pleasantest 
excursions afield which can be made are those which the 
naturalist takes, when he has only moonlight or starlight to 
guide his steps. Always take a dark lantern with you. Without 
it you cannot see, and even with it you will not see much which 
it might be delightful to behold. But without a lantern you will 
not see a great deal, and you may in the thick wood get deeply 
mired in a boggy hole, or even break a limb. Your eyes are not 
made like those of the owl and the cat. Do not be afraid of the 
“night air.” The air of the night has the same chemical com¬ 
position as the air of the day. It is cooler, of course, and some¬ 
times it has fog in it, but cool and even foggy air is not un¬ 
healthful. Scotchmen live half their lives in fog, but are healthy. 
The only things to be dreaded are the mosquitoes, carrying with 
them the germs of malaria, as we call it. These may be kept 
off if you only know how to anoint yourself with a properly 
prepared lotion. 
FAMILY SATURNIIDAE 
“ When, hypocritically clad in dressing-gown and slippers, I stopped 
at my guest’s inner door and Fontenette opened it just enough to let me 
in, I saw, indeed, a wonderful sight. The entomologist had lighted up the 
room, and it was filled, filled ! with gorgeous moths as large as my hand 
and all of a kind, dancing across one another’s airy paths in a bewildering 
maze, or alighting and quivering on this thing and that. The mosquito- 
net, draping almost from ceiling to floor, was beflowered with them, 
majestically displaying in splendid alternation their upper and under 
colors, or, with wings lifted and vibrant, tipping to one side and another 
as they crept up the white mesh, like painted and gilded sails in a fairies’ 
regatta.”—G. W. Cable. 
This family is composed of moths, which are for the most 
part medium-sized or large. The larvae are cocoon-makers. The 
perfect insects have vein 8 of the hind wings diverging from the 
cell from the base of the wings. The frenulum is wanting. The 
tongue is aborted, being at most extremely rudimentary. There 
are no tibial spurs on the legs. The antennae are either singly or 
doubly bipectinated to the tips in the case of the males, and 
often in the case of the females. Bipectination of the antennae 
occurs also in the family Ceratocampidce , but in the latter family 
it never extends to the tip of the organ. The family falls into 
three subfamilies: the Attacince; the Saturniince; and the Hemi-
