in Mesopotamia. Eri seed cocoons were sent to the Ento- 

 mological Department, Egypt, where the worms are being 

 reared successfully, to the Department of Agriculture in 

 Mauritius, and to the Salvation Army for sending to East 

 Africa. Eri and mulberry silkworm eggs were supplied to 

 84 and 85 applicants respectively, and mulberry seeds and 

 cuttings and castor seeds were supplied to 14 applicants. 

 Uni vol tine eggs of French and Japanese races, and 

 Japanese bivoltine eggs, were sent to Guindy, Shillong and 

 Muktesar for cold storage, and were successfully reared at 

 Pusa in October, 1917, and March, 1918. Eggs of two 

 Chinese univoltine races were received from the Salvation 

 Army, Simla, and were successfully reared. 



Seven students completed short courses in sericulture 

 during the year and three students remained under traiiir 

 ing at the close of the year. Of the seven who completed 

 their courses one came from Travancore, one from the 

 Salvation Army Silk School at Bangalore, one from Bengal, 

 and two each from Bihar and Indore. 



A Second Report on the Experiments carried out at 

 Pusa to improve the Silk Industry in India and a pamphlet 

 on the anatomy of the silkworm and moth were published 

 during the year; a Bengali translation of the former is in 

 the press and one of the latter was published in the Krishi 

 Sainpada of Dacca. 



V. Illustrations. 



Coloured plates illustrating the life-histories of the 

 following insects were prepared during the year, viz., 

 Pseudococcus sp. causing tukra disease of mulberry, 

 Ophideres materna, C ryptorrhynclius gravis, Platyptilia 

 pusillidactyla and Eretmocera impactella. Drawings in 

 black-and-white, showing life-histories in more or less 

 detail, were prepared of about seventy of the insects reared 

 in the In sectary, and about the same number of other draw- 

 ings of insects were also done. 



Thirty-four new coloured plates of pests were issued in 

 the Report of the Proceedings of the Second Entomological
