PLUMERIA (named in honour of Charles Plumier,

Syn. Himatanthus. ORD. Apocynacee. A rather large 
genus (about forty species have been described) of 
glabrous or pubescent stove trees, with thickish branches, 
natives of tropical America. Flowers white, yellowish, 
or rose-purple, large, in terminal cymes. Leaves alter- 
nate, often on long petioles, penniveined. ‘The species 
thrive best in a compost of sandy loam and fibry peat. 
Propagated, in spring, by cuttings of ripe shoots, inserted 
in sand, under a handlight. Very few species are now 
in cultivation,

PLUSIA. A genus of Noctwide, the larve of some 
of which do considerable injury to cultivated plants. The 
British species vary between ljin. and 14in. in spread of 
wings, and they almost all possess shining metallic, 
silvery, or golden spots and markings on the rather 
crests of hair-like scales. The moths generally fly dúring 
the day; when at rest, the wings are held like a roof 
over the hinder part of the body. The larvæ are rather 
Parinarium 
slender, tapering markedly towards the whi 
siendo, tapering mar ls the head, which 
larvæ. When full-fed, they spin loose cocoons at 
dead leaves, or on the food-plants, and in these become 
black pupæ. Two, or even more, broods may be hatched 
in a year. : 
The larve of several species feed on Groundsel, Nettles 
and other low weeds, and may at times devour cultivated 
plants along with these; but the only species that is really. 
dangerous to garden and field produce is P. Gamma, the 
too well-known Silver Y, or Gamma Moth. The larva 
of the moth is, indeed, one of the worst pests at times, 
alike in the garden and in the field. The moths may 
be seen, from June to the end of October in some years 
flying in the bright ganshine, and not less in the twilight. 
nor do they cease to fly even at night. Frequently, they 
swarm in myriads in hay-fields, among Turnips, in gardens, 
and, in fact, everywhere, Some idea of the form, size, 
and markings, may be obtained from Fig. 208, in which, 
however, the characteristic silvery mark. the front 
wings, like the Greek letter gamma (y), or the letter Y. 
is not well shown. It is plainest in the left wing near 
the middle. The front wings are grey or violet-grey,
