AND COLLEGE, PUSA, FOR 1915-16 67 



The life-history of Ancylolomia chrysographella was 

 -also traced throughout the cold weather (November- 

 February). This moth hibernates in the larval stage and 

 breeds continuously in the hot weather. 



Two tube-forming Tineid larvae, Melasma sp. and 

 Myrmecozela leontina, both with only one brood in the year, 

 were also under observation. 



The life-history of Leucophlebia lineata (Sphingidae) 

 was traced throughout the year. The larvae were noted to 

 hibernate as well as aestivate. 



Oides bipunctata (Chrysomelidae) has been observed to 

 .hibernate and aestivate in the egg stage. 



'Poly tela gloriosce (Noctuidae) has been observed to 

 .hibernate and aestivate in the pupal stage. 



The already known habit of larval aestivation in Muda- 

 ria cornifrons (Noctuidce) was confirmed by further observ- 

 ations. 



In connection with other experiments on Bactrocera 

 -cucurbitce (Trypaneidae) it was noted that this Fruit-fly is 

 capable of living in confinement in the adult state for a 

 period of over three months. Under natural conditions it 

 seems probable that many Fruit-flies live over from season 

 to season in the adult state. It was also noted that stems 

 of Cucurbitaceous plants and galls thereon, caused by 

 Cecidomyiadae or otherwise, were as favourable breeding- 

 places for these flies as the fruits themselves. 



In addition to the foregoing, complete cycles were 

 -observed of Danais plexippus (on Oxystelona esculentum, 

 .a new food-plant), Kolla mimica on paddy, a Jassid bug on 

 sugarcane leaves, another Jassid on leaves of Cyperus 

 rotunda (Mutha), Polia consanguis, a Halticid beetle on 

 A nisomeles ovata, and Cyrtacanthacris ranacea. 



A few broods from known parents were reared of 

 Terms hecabe and Papilio polytes to ascertain proportional 

 variation. 



Further observations were made on the habits of Tene- 

 Jbroides mauritanicus, Odoiporus longicollis, Attagenus
