66 PROCEEDINGS OF THE SECOND ENTOMOLOGICAL MEETING 
The seedlings are attacked by 
Chrotogonus spp. 
Flea-Beetles, 
and of course by Utetheisa and other insects which we shall come to 
under the heading of leaf-pests. 
Chrotogonus, probably several species, attack the young seedlings. 
They may be dealt with by means of bag-nets. 
Flea-Beetles are common pests on seedlings all over India and have 
been noted to do damage in Madras, Bombay, the Central Provinces, 
Bihar and Burma. This is a group in which we are at present very 
ignorant of the identity of the species, and I cannot say more than that 
several different species are probably concerned. Spraying in small 
plots or catching the beetles by means of nets will usually provide 
control. 
On the leaves we get a good many pests :— 
Utetheisa pulchella. 
Argina cribraria. 
Argina syringa. 
Argina argus. 
Amsacta mooret. 
Plusia signata. 
Euproctis scintillans. 
Amyna octo. 
Chaetocnema basalis. 
Tanymecus indicus. 
Myllocerus blandus. 
Utetheisa pulchella is probably the most important pest of Sann- 
hemp in India and attacks not only the leaves but also the pods and 
seeds as well. It is figured and described in “ South Indian Insects ” 
[pp. 371-372, fig. 233] and we have since issued a coloured plate showing 
the stages. 
Control is very difficult. In the case of small plots spraying and 
handpicking are of course useful and in the case of young plants bagging 
may collect a good many larve, but on a field scale with well-grown 
plants, handpicking, bagging and spraying are alike impracticable. The 
moths themselves are active and cannot be checked by hand-nets or 
light-traps ; they fly very actively by day and a few come in to light 
in the evening. The pupe may occur in folded leaves on the plants or 
on the surface of the ground, and we practically cannot get at them 
whilst the crop is standing. At present I can only suggest two lines of 
work, both of which require investigation. One of these is an appli- 
cation of clean cultivation and rotation to try to check the insect by
