130 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
HouiyHock (Althea rosea). 
Hollyhock is a common garden plant and we have also been using 
it in our bollworm parasite-breeding plots. It is also being used in the 
Rhogas breeding-plots. 
The leaves are attacked by :— 
Sylepta derogata. 
Spialia galba. 
Acontia sp. 
Sylepta derogata rolls the leaves much as in the case of cotton and 
bhindi. ; 
Spialia galba (Hesperiade) is widely distributed throughout the 
Plains of India and at Pusa has been reared from larvee on hollyhock 
leaves, and also on Sida rhombifolia and soy-bean. It is not a pest. 
We have also a record of an Acontia larva found on the leaves, but 
it was either not reared or not named. 
The flowers and pods provide food for Harias insulana and E. fabia, 
which will breed in hollyhock but it is not a very favourite foodplant. 
Gelechia gossypiella has also been recorded as “on hollyhock”’ at 
Pusa but here again we have a case of defective labelling. Probably 
it does occur in hollyhock as it has been reared from this plant in Egypt. 
The sucking insects found on hollyhock include :— 
Dysdercus cingulatus. 
Oxycarenus letus. 
Corizus rubicundus. 
Nezara viridula. 
Dysdercus cingulatus is decidedly fond of hollyhock and almost 
every garden-plant usually has some of these bugs on it. 
Oxycarenus letus occurs on the dry pods. 
Corizus rubicundus is common on garden plants, often in numbers, 
and is a minor pest. 
Nezara_ viridula also sometimes occurs In some numbers on the 
flower-stems. 
Sitk Corron (Bombax malabaricum). 
| Simul—Hind. | 
Silk-cotton belongs to the Malvacez but differs from the other plants 
of this Order by having rather a peculiar insect-fauna. We find a good 
many insects which seem confined to Bombax and do not occur on cotton, 
Hibiscus, etc.
