PROCEEDIN'GS OF THE TIIIKD ENTOMOLOGICVL MEETING. 547 



Mr. Willcocks' paper and letter answer the question asked just Mr. Fletober. 

 now by Mr. Burt regarding the survival of Pink Bollwoim larvae in 

 bolls which drop off and remain in the field. Of course, these residts 

 have been obtained in Egypt and require checking in India, but the 

 conditions are very similar and I have little doubt but that the larvae 

 do survive, probably over more than one year in many cases, in India 

 also. 



I should Hke to say how much we feel indebted to Mr. Willcocks 

 for sending us this very complete information and also to Dr. Gough 

 for coming here from Egypt and telling us all about their cotton pests. 

 It woiild perhaps be out of place for us to pass a formal vote of thanks 

 to the Ministry of Agriculture of His Majesty the Sultan of Egypt for 

 sending Dr. Gough to India to attend our Meeting, but I propose to 

 ask the Government of India to thank the Egyptian Government for 

 sending an official delegate in the person of Dr. Gough. We hope 

 that this is not the last Meeting at which we shall see a representative 

 from Egypt. 



I wish to thank Mr. Fletcher for all that he has said. I have learnt Dr. Ooogb. 

 a good deal at this Meeting and the Egyptian Government has got good 

 value for its money.

20.— SOME PESTS OF COTTON IN NORTH BIHAR. 



By C. S. MiSRA, B.A., First Assistant to the Imperial Entomologist. 



We first devoted^. ourselves to the study of the cotton pests in 1906 

 when a greater portion of the cotton crop was damaged by the boll- 

 worms, Earias fahia and E. insulana, in the Punjab. Subsequently 

 when there was a partial failure of the cotton crop in Sind in 1907 

 and I was deputed by the Imperial Entomologist to make investigations 

 regarding the incidence of the bollworm attack, the percentage of 

 parasitization, etc., at the instance of the Bombay Government, the 

 importance of a detailed study of the cotton pests was fully brought 

 to the fore. For a few years subsequent to these preliminary investi- 

 gations we devoted ourselves to the study of the parasites and had 

 some cotton grown at Pusa to allow the parasites to breed and to 

 distribute them to such places, especially the Punjab, when required 

 to do so. Prior to these investigations, some experiments regarding 

 the suitabiUty of cotton as a field crop in North Bihar to make up the 

 loss caused by the low prices of indigo due to the introduction of 

 synthetic colours were carried out by the Imperial Agriculturist, Pusa. 

 In these experiments the varieties of tree cottons, as well as exotics,
