PROCEEDI>fGS OF THE THIRD ENTOMOLOGICAL MEETING 53 



The larva measures nearly 8 mm. in length, a few hours after emersfence 

 and is dull white ; head round and shiny ; body is thinly hairy with dark 

 hairs.- As the larvae are growing the bodily colour is changed to brown. 

 The caterpillar when full-grown measures little more than 25 mm. in 

 length and is deep brown in colour. 



The insect feeds openly on Cowpea ( Vigna ca(jang) and is a very slow 

 eater. They destroy the leaves. It is only a very minor pest. The 

 full-grown larvae could be found in nature wandering in the fields. 

 When disturbed the larva falls down from the foodplant and curves 

 itself. A few larvae were found dead in the cage, and it was observed 

 that other larvae were eatmg the dead body of their own species. 

 The larva in nature is as a rule found isolated and not in groups. 



The insect commenced pupation on the 2nd of October. The newly- 

 formed pupa is .very soft and pink in colour and towards the close of the 

 pupal period the colour became more pinkish. Abdominal spiracles 

 and wing pads are very black. Pupa measures about 12 mm, in length 

 and 35 mm. across the body. 



The insect makes a slight cocoon with silken threads and remnants 

 of the foodplant. It makes its cocoon on the foodplants in nature. 



The moths commenced to come out from 16th October and continued 

 for 2 days more. 



Eggs laid on olst August 1918.

 cultivated crop.]
