PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 255 
up the caterpillars is the best method as a rule. Spraying is not effective, 
as the caterpillars prefer to feed on the roots and underground portions. 
of the stems. 
Eating the leaves we find :— 
Plusia orichalcea. 
Monolepta orientalis. 
Epilachna 25-punctata. 
‘ 12-stigma. 
Flea beetles. 
Atmetonychus peregrinus. 
Myllocerus subfascvatus. 
Plusia orichalcea is scarcely a pest on potato. 
Monolepta orientalis was found at Rangpur. Otherwise we do not 
seem to know this insect. 
Epilachna 28-punctata and E. dodecastigma [‘‘South Indian Insects,” 
p. 292, tab. 6] both occur commonly on potato and sometimes do con- 
siderable damage in the Plains. Collection by hand of the insects in all 
stages and in bad cases spraying of the affected plants will provide 
control. : 
Flea-beetles occur commonly as minor pests, occasionally serious, 
but we know nothing of the species concerned. Collection by hand- 
nets, where necessary, will provide control. 
Atmetonychus peregrinus was found on potato at Cuttack but was 
probably a mere casual visitor and not a pest. 
Myllocerus subfasciatus is recorded on potato at Ootacamund, but 
we do not know how far it is a pest. 
The sucking insects found on potato include :— 
Nezara viridula. 
Aphids. 
Nezara viridula is figured in “ South Indian Insects,” pp. 473-474, 
fig. 352, and the life-history is shown in a coloured plate since issued. 
It may be observed that the coloration of both immature and adult 
bugs is very variable. Nezara viridula is fairly common on potato, 
usually occurring as a minor pest. The bugs may be collected in hand- 
nets. 
Aphids are of common occurrence on the leaves and stems and con- 
siderable damage may be done at times, but control on a field scale is 
rather a matter for natural predators. 
The roots and tubers are attacked by :— 
Dorylus orientalis. 
» labiatus.
