INSTITUTE AND COLLEGE, PUSA, FOR 1907-09. 3 



arranged and catalogued. Mr. C. W. Mason has arranged 

 the Lepidoptera, the Assistant to the Second Imperial 

 Entomologist the Coleoptera. A large part has been sent 

 to England for the use of authors of prospective volumes of 

 the fauna of India; the Orthoptera, Neuroptera, Braconi- 

 dae and Ichneumonidas, Cetoniidse Chrysomelidse, Curculi- 

 onidse, Microlepidoptera and Rhynchota Homoptera are the 

 larger collections being worked at in this way. A large 

 part has been returned, and the whole collection is yearly 

 becoming more complete and useful. The greatest help was 

 given by the late Colonel Bingham, and by his death we have 

 lost an able collaborator who gave invaluable assistance to 

 all who are interested in Indian entomology. We have 

 now a good reference collection as well as a separate 

 collection for students, of the insects of Pusa, both of which 

 are necessities in daily work. In conjunction with the 

 Indian Museum, the results of the past work are being 

 worked up and utilised in determining the zones of insect 

 life in India. Specimens were exchanged with the Indian 

 Museum; a collection of Coleoptera was identified for the 

 Bombay Natural History Society and completed from our 

 duplicates. Similar collections were identified and made up 

 for provincial agricultural colleges, and their collections 

 are sent here for identification and arrangement. A good 

 collection is the basis of accurate work and teaching, so that 

 this work is of importance and can be done from Pusa only. 

 The formation of the collection will be continued, but less 

 time will be devoted to it. 



10. Demonstration. — A series of excellent coloured 

 plates with short printed explanations, has been issued, 

 which are used for teaching in colleges, are exhibited at 

 demonstration farms and are made up into show-cases for 

 exhibitions and shows. This series will be continued and 

 is being expanded also to cover silk, lac, bees and beneficial 

 insects. As the work of the provincial departments 

 expands, this work will also expand; and, since only simple 

 methods of checking pests can be used, the teaching of the 

 people and the demonstration of simple facts and remedies
