The following miscellaneous Lepidoptera are minor pests: Plutella 
maculipe nnis (Curt.) in North Caucasus; Depressari a ricinella Strand in 
India; Synt o moi des imao n (Cram.) in Ceylon; Clani a cramer i (Westw.) in 
India; C. va rie g ata formosicola Strand and Stathmc poda theoris Meyr. in 
Formosa; Emg sis mandana (Cram.) in Lagarto, Brazil; Zebronia phenic e (Cram.) 
in Uganda; Nudau reli a wahlbergii (Boisd. ) in Natal and Tanganyika; and N. 
dione (F.) in Uganda. 
Several insects in the order Hemiptera have been recorded as very in- 
jurious to the castor-bean plant. 
Nezara viridula (L.) seems to be the most injurious. It has been 
recorded from Nyasaland, Egypt, and Costa Rica. An unpublished note from 
C. H. Ballou stated that he observed the insect feeding in Venezuela in 1938. 
Plant quarantine inspectors intercepted the insect coming into the United 
States from Mexico. N. robusta Dist, attacks the plant in Nyasaland. 
Acrosternum pa lli doconspersa (Stal) causes considerable injury in the 
Italian Somaliland and in Madagascar. A. marginatum (Beauv.) injures the 
plant in Costa Rica. 
Minor pests include the pentatomids Chr ysocori s stolli (Wolff.) and 
C. a bdominali s (Westw.) in the Malay Peninsula, Edess a cornut a Burm. in 
Costa Rica, and Dalpada smaragdina (Walk.) and Erthesina fullo (Thunb.) 
in Taiwan. 
The lacebug Cpryt huch a gossypii (F. ) has been rcorded as of economic 
importance in several of the West Indian Islands, i. e., Puerto Rico, Cuba, 
Virgin Islands, St. Vincent, Antigua, Grenada, Trinidad, and also in Mexico, 
Costa Rica, and India. It was observed by C. H. Ballou in Venezuela in 1938. 
Corythaica monacha (Stal) occurs in Rio Grande do Sul in Brazil, and Garg - 
aphia lunulata (Mayr) in Minas Geraes, Brazil. 
Injurious mirids include Poec ilc scytus cogn atus Fieb., which causes a 
great deal of damage in the North Caucasus, and Ade l phocori s lineolatu s 
(Goeze), which is also widely distributed in the North Caucasus, although 
the damage is negligible; Helcpeltis bergrothi Reut . and E urystylus ki vuensis 
Schouteden in the Belgian Congo; and Platytylellus a tri pennis (Reut.), which 
is numerous in Cuba, although the damage is light. An undetermined mirid was 
swept from the plant in Costa Rica. 
A coreid, Hypselonotus atratus Dist., has been reported from Costa 
Rica. A pyrrhocorid, Eurycphthal mus cinctus (H.-S.), was observed by C. H. 
Ballou in Venezuela in 1938. 
Several leafhoppers in the genus Eirpo _asc a are recorded as feeding on 
the castor-bean plant. E. flavescens (F.) sometimes appears in swarms in 
India and Egypt, and when the castor-bean plants are young, the leafhoppers 
suck the juices of the plants to. such an extent that the plants fade, curl.
