292 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
Aspidomorpha indica seems to be widely distributed throughout 
India and Burma and has been reared on sweet potato at Moulmein 
and Pusa. It is scarcely a pest. 
Pilemostoma trilineata we have from Tatkon (Burma), Lebong, 
Masuri, Chapra and Pusa. At Tatkon it was found on sweet potato 
and has been bred on this at Pusa. It is an occasional minor pest. 
Metriona varians has been reared at Pusa on sweet potato and has: 
also been found on Ipomea sp. at Bulsar (Bombay). It is scarcely a 
pest. 
Metriona circumdata has been reared on sweet potato at Pusa and we 
have it also from Chapra, Dacca and Surat. It is scarcely a pest. 
Coptocycla sp. [‘‘ South Indian Insects,” p. 317, fig. 169] occurs in 
Madras on sweet-potato but is scarcely a pest. 
Another Cassid, unidentified as yet, was found on sweet potato at 
Moulmein. 
Oncocephala tuberculata (Hispinee) has been reared on sweet potato 
at Pusa and Coimbatore and we have it also from Bulsar (Bombay). 
It is not a pest. 
Blosyrus asellus |Marshall, Fauna of India, Curculionide, I, 33] 
has been found at Pusa in small numbers on sweet: potato, but is not a 
pest. 
Myllocerus sabulosus {l.c., p. 336] has also been found on sweet potate 
at Pusa but seems to be a mere casual visitor. 
The stems of sweet potato are attacked by : 

Gonocephalum sp. 
Omphisa anastomosalis. 
Cylas formicartus. 
A small species of Gonocephalum was found at Moulmein in September 
1914 on the soil around sweet potato plants whose stems were found 
dead or dying, evidently as the result of some insect attack. The 
beetles were not actually noticed to eat the stems but the circumstances 
were decidedly suspicious. 
Omphisa anastomosalis is cluded in “ South Indian Insects,” pp. 
439-440, fig. 316, as a potential pest of sweet potato. It is common 
in India, the larva boring in stems of wild Ipome@a, but has not yet 
actually been found on sweet potato. I expect, however, that it will 
occur. 
Cylas formicarius bores in the shoots but we will take it under tubers. 
The tubers of sweet potato are attacked by :— 
Cylas formicarius. 
Metasia coniotalis.
