and eventually die. The species is distributed throughout the southern part 
of the peninsula of India, in Ceylon, and in the Malay Peninsula. E. faci - 
alis (Jac.) sometimes causes considerable injury in the Niger Valley of 
Africa and in the Italian Somaliland and the Khartoum district of the Anglo- 
Egyptian Sudan. E. notata Mel. occasionally causes injury in India, although 
it is not usually destructive to the plant grown as a field crop. E. formo - 
sana Paoli has been recorded from Taiwan. E. solana DeLong causes a disease 
of the plant in Hawaii. 
C icadella a reolata (Sign. ) and Diedrocephala limbaticollis (Stal) were 
swept from the foliage in Costa Rica. Undetermined leafhoppers are recorded 
as abundant in the Khartoum district of the Anglo-Egyptian Sudan and Tangan- 
yika. 
The treehoppers Entylia sinuata (F.), Spongophorus ballista (Germ.), 
and Micrutalis sp. were swept from the foliage in Costa Rica. 
The fulgorids Dictyophora florens (St^l) and C olpoptera sinuata 
(Burm.) were swept from the foliage in Costa Rica, and Ormenis quadripunctata 
(F.), are recorded from Puerto Rico. 
Aphids are recorded as being attracted to the plant in India. Myzus 
persi cae (Sulz.) is recorded from the plant by Wilson and Vickery, in Aphid- 
idae of the World, 1918, without reference to locality. This species was 
recorded in the North Caucasus in 1927 and 1928, although it caused no notice- 
able damage. M. ornatus Laing was intercepted coming from England, on leaves 
of castor. 
A whitefly, Trialeurodes ricini (Misra) , is common in India. It 
sometimes occurs by the thousands on the under surface of the leaves, 
especially on well-grown plants. It gives entire fields an ashy-white 
appearance. A species of T rialeurodes occurs in Siam. An undetermined 
aleyrodid, similar to Bemisia goss ypiperd a Misra & Lamba, which attacks 
cotton in the Punjab and in the Sudan, is often present in Iraq, especially 
where the cotton is overshadowed by the castor plant. 
Scale insects are rarely found to be injurious. Saissetia nigra 
(Niet.) is the most common in India, but it seldom causes much damage. 
It has also been recorded from the Virgin Islands and the Seychelles Islands. 
S. hemisphaerica (Targ.) has been recorded from the Virgin Islands and the 
Canary Islands. S. oleae (Bern.) has been recorded from the Virgin Islands. 
Aonid ie lla aura n tii (Mask.) has been recorded from Rio Grande do Sul, 
Brazil, from Egypt, and from Palestine, and A. orientalis (Newst.) from 
southern India and the Italian Somaliland. 
Aspidiotus destructor Sign, has been recorded from Zanzibar, the 
Italian Somaliland, and Cuba, and A. hederae (Vallot) from Syria, Palestine, 
Rhodes, Portugal, Algeria, and Morocco. A. latania e Sign, occurs in small 
numbers in Egypt.
