49.— EXHIBITION OF DRAWINGS, BY MAJOR F. C. FRASER, 

 I.M.S., OF EARLY STAGES OF INDIAN BUTTERFLIES. 



Last year Major Eraser very kindly sent me a note-book coutaining "^''' *^'*'Cher 

 a large number of coloured drawings of the early stages of Indian Butter- 

 flies. In some cases the complete life-history is shown and in many 

 cases I think that we have no published information on these early 

 stages. 



50.— THE LIFE-HISTORY OF ORTHEZIA INSIGNIS. 



(.Abstract.) 



By K. KuNHi Kannan, M.A., F.E.S., Senior Assistant Entomologist. 

 Mys&re. 



This j)est was discovered for the first time m the Nilgiris by a 

 European planter in 1915. It was sent in for identification by 

 Mr. Anstead. When it was determined as Orlhezia insignis, it was 

 decided to test the effect of its attack on Lantana. In the course of 

 observations, the life-history was studied of which the following are the 

 more important details. The insect moults three times, the mterval 

 between successive moults being roughly about two weeks. In about 

 two to two and a half months the iascct begins to reproduce, the total 

 number of young produced varying from 80 to 110. The total period 

 from hatching to death is about four and a half months. 



The insect is not much attended by ants and the honey-dew is more 

 of a solid nature and little in quantity. Transmission exp)eriments on 

 the lines described in the Bidletin on Scale Insects of Coffee (Dept. of 

 Agri., Mysore) failed to induce the species of ants experimented with to 

 caiiy the insect to their nests. The insect retards the growth of Lantana 

 and finally kills it. One bush on which it was introduced, measuring 

 f.tout three feet high and four feet in diameter, was killed in three years.
