104 SCIENTIFIC REPORTS OF THE AGRICULTURAL RESEARCH 



REPORT OF THE IMPERIAL PATHOLOGICAL 



ENTOMOLOGIST. 



(E. M. HOWLETT.) 



I was in charge of the Section for the year, except for 

 an absence on privilege leave from 9th to 23rd December, 

 1918, when Mr. Patel was in charge. 



For practically the entire period, however, I was on 

 special duty, in connection, firstly, with the prevention of 

 surra-transmission by Tabanidse, more particularly among 

 transport camels, and, secondly, with the improvement of 

 existing culicifuges for military use. Reports on the work 

 done in these two directions have been separately submitted. 

 Little has been done outside these special enquiries, but 

 Mr. Patel, besides continuing his work on midges and com- 

 pleting the manuscript of a book on cattle-flies, has studied 

 the parasites of some animals and birds likely to be asso- 

 ciated with human beings, and has made several new dis- 

 coveries, including a blood-sucking muscoid larva with 

 habits comparable to those of the notorious " Congo floor- 

 maggot." Messrs. Sen and Sharma have continued, when 

 circumstances permitted, the physiological work on mos- 

 quitos referred to in the programme for the year. 



In January I attended the Science Congress in Bombay; 

 in March the Veterinary Conference at Lahore; in April 

 and May meetings of the Drugs Committee at Simla and the 

 Surra Research Committee at Delhi. 



The following papers were read at the sixth session of 

 the Indian Science Congress held at Bombay : — 



' Post-war Zoology " (Presidential Address to Zoolo- 

 gical Section). E. M. Howlett. 

 " Tactics against Insects ' (Evening lecture). F. M. 



Howlett. 

 " Life-history of a midge, Culicoides oxystoma, with 

 some remarks on the early stages of Cerato- 

 pogon." P. G. Patel.
