(O. picipes, Fig. 767). These are practically omnivorous 
so far as garden produce is concerned, but are especially 
destructive to Vines, Strawberries, Raspberries, Goose- 
berries, Apples, Ploms, Peaches, Ferns, and many 
flowering plants. All are night-feeders, and should

be sought for by artificial light. They are easily alarmed, 
and if a light be suddenly turned upon them, ora slight 
tap be given to the infested trees, the insects will drop. 
If, therefore, some sticky compound be arranged upon 
boards or papers, and laid beneath the plants, the pests 
may be prevented from escaping, and afterwards thrown 
into boiling water.

Kastern Asia, Australia, and the Pacifie Islands. 
Flowers shortly racemose or spicate at the tips of

WISTARIA. To cultivate W. chinensis successfully 
it should be allowed plenty of head room, a fairly rich 
soil, and a sunny position. W. multijuga is not so well 
known, and, though shy in a young state, is neverthe- 
less well worth growing. To the species and yarieties 
described on pp. 213-4, Vol. IV., the following should be 
added : : 
W. chinensis alba (white). jl» white, very sweet-scented ; 
racemes smaller than in the type (Fig. 768). The plant 
is also rather less vigorous and not so floriferous. 
W. floribunda (abundant-flowered). A synonym of W. chinensis, 
W. frutescens. The following are varieties: alba (SYN. nivea), 
flowers white; Backhousiana, violet, in long, compact racemes ; 
magnifica, clear blue, with a greenish-yellow spot on the 
standard, leaves very velvety ; purpurea, purple-violet. 
W. japonica. This name is kept up in the Kew Hand-list, 
but according to Asa Gray and the “Index Kewensis,” the 
correct name is Milletia japonica. 
W. multijuga. According to the “ Botanical Magazine" (7522), 
this is a form of W. chinensis. The variety alba has flowers 
wholly white.
