TIGER MOTHS. A name commonly applied to 
several moths of the tribe Bombycina (see Moths), 
probably on account of the bright, variegated colours 
of its more conspicuous members. The larve of all 
the Tiger Moths are rather thick-bodied, and are closely 
covered -with long, stiff hairs, usually brown or black, 
rising from numerous prominent warts along the back 
and sides. They feed on low plants, chiefly herbs, and 
seldom do much harm in gardens, as they prefer Dock, 
Plantains, and other weeds, rather than cultivated plants. 
In autumn, and again in spring, the larve of the Common 
Tiger, and of the Ruby Tiger, are to be seen on every 
road, crawling in search of food or of safe retreats for 
the winter, or for pupation. When full grown, in spring 
or early summer, they spin slight cocoons on the food- 
plants, or among dead leaves and surface rubbish, and 
in them become pups», from which the moths emerge 
in two or three weeks. The species of most common 
occurrence in gardens are the two just mentioned. 
The common Tiger (Arctia caja) varies in size from 
2in. to 3in. across the fore wings, which are brown, with 
irregularly branching, pale cream-coloured lines and spots. 
The hind wings are red, with six or seven blue-black 
spots, of which three lie in a band parallel to the hind 
margin. The head is brown, with a crimson collar; the 
thorax is brown; and the abdomen is crimson, with a 
series of oblong, black spots down the middle, and a 
row of black dots along each side. This species is very 
apt to vary in the colour of the wings; in some the 
dark tints prevail, in others the pale. The larva of this 
Moth is known generally as the “Woolly Bear,” from 
its dense coat of long hairs. The latter, on the back, 
are dark near their bases, grey near the tips; along 
the sides and near the head they are brown. The larve 
hybernate while small, and feed up in spring, when 
they subsist on a great variety of plants in gardens. The 
moths usually emerge about July. 
The Cream-spotted Tiger Moth (Arctia villica) is a little 
like A. caja, but smaller, as it does not exceed 2łin. 
in spread of fore wings. This species is black, with 
Fie. 34. CREAM-SPOTTED TIGER MOTH. 
eight cream-coloured spots (see Fig. 34). The hind wings 
are orange-yellow, with a few small, central, black spots, 
and an irregular, black band along the hind margin. 
The larva is a good deal like the “ Woolly Bear,” and, 
like it, feeds on various herbs. __ 
_ The “ Wood Tiger” (Nemeophila Plantaginis) seldom 
ceeds 1jin. across the fore wings. These are black, 
Tiger Moths—contimued. 
The hind wings are dull, deep yellow or orange, with 
velyety-black markings, in the form of black spots, 
along the hind margin, and at the base. The larva is 
hairy; the hairs near the end of the body are black, 
those in the middle of the body are red-brown. It 
feeds on low weeds, and is scarcely ever seen in gardens, 
as this moth frequents moors. 
The Scarlet Tiger (Callimorpha Dominula) is confined 
to localities where the Hound’s-tongue (Cynoglossum) 
grows. It reaches about 2iin. across the fore wings, which 
are dark olive-brown, with a metallic-green lustre, and 
bear about ten spots, those in the centre yellow or 
orange, the others cream-coloured. The hind wings are 
crimson, with large, black spots near the margins. 
The Ruby Tiger (Phragmatobia fuliginosa) differs from 
all the above alike in size (about 1}in. across the front 
wings) and in colour. The fore wings are dull red- 
brown, with two black dots near the middle. The hind 
wings are dull pink near the base, smoky-brown near 
the margin, and have two dark dots near the middle; 
the fringes are pink. The head and thorax are brown; 
the abdomen is pink, with one central and two lateral 
rows of dark spots. The larve are yellowish-brown, 
smoke-coloured, or dark, and very hairy. They are 
often to be seen in autumn, seeking secure retreats for 
the winter, and in spring they emerge from their retreats 
to feed up. In April or May they spin loose, oval 
cocoons among herbage, and become dark pupæ; from 
these the moths emerge in June. The larve feed 
chiefly on low weeds, but may at times live on garden 
produce. 
All the Tiger Moths have thick, heavy bodies. 
fly at all hours by day, and also by night. 
Should the larva ever become too numerous, hand- 
picking is the best remedy.

TIGRIDIA (from tigris, a tiger, and eidos, like; in 
reference to the spotted flowers). Mexican Tiger Flower; 
Tiger Iris. Syns. Beatonia, Hydrotenia. Onrp. Irideæ. 
This genus includes ahout seven species of greenhouse 
or half-hardy, bulbous plants, from Mexico, Central 
America, Peru, and Chili. Flowers few in a spathe, in , 
one species (T. pavonia) very large; perianth concave, 
with no tube; segments free, the outer ones very broad, 
unguiculate, the inner ones much smaller and erecto- 
patent, often obtuse, more or less undulated; filaments 
connate in a cylindrical tube; spathe one, terminal, or 
two at the axils of the floral leaves, long and unequally 
pedunculate. Leaves at base of stem few, narrow, or 
broader and plicate-veined; cauline or floral ones often 
two or three, scattered. T. pavonia and its varieties 
are very handsome subjects when in flower. All the 
species thrive best in a light, sandy soil; if planted 
outside, a warm, sunny position, with south aspect, should 
be accorded them. The roots must be lifted in the 
autumn, when the leaves have died down, stored away 
in some place where frost cannot reach them, and re- 
planted in the following April. Propagation may be 
effected either by seeds or by offsets.
