SO SCIENTIFIC REPORTS OF THE AGRICULTURAL RESEARCH 



Hieroglyphus banian. In the Insectary there is a cage 

 into which a pair was introduced in 1905. Since then they 

 hatch out regularly every year in that cage and are fed 

 and allowed to oviposit. The broods have been observed 

 to extend gradually. Last year (1916) they hatched in June 

 and the last of the adults died on 15th February, 1917. Of 

 course different batches of eggs hatched at different inter- 

 vals up to August. 



Some individuals of Poly tela orientals have been 

 observed to rest for the whole year in the pupal stage, whilst 

 others emerged in the first year. 



Melittia eurytion, which bores and causes a swelling, in 

 the stem of Trichosanthes dioica and other cucurbitaceous 

 plants in the Rains, has been observed to rest for the re- 

 mainder of the year in the larval stage inside a very stiff 

 cocoon. 



CosTtrQ'pteryx manipularis, sl miner in bean leaves, has 

 been observed to rest in the larval stage from about Novem- 

 ber to July. 



The Cerambycid borer occurring in Phaseolus aconiti- 

 folius stem in the Rains, has been observed to rest for the 

 remainder of the year in the larval stage. 



Oides bipunctatus has been observed to have onlv one 

 generation in the active season in the Rains, the rest of the 

 year, as reported before, being passed in the egg stage. 



The Eurytomine Chalcidid grub in apricot seed prob- 

 ably rests for two years inside the seeds in some cases, 

 although most come out as adults after one year. In the 

 Insectary some grubs were observed to rest for about a year 

 and a half and then die. 



Agrypnus fuscipes. One grub about one-third grown 

 was collected in November 1914. It lived and grew in the 

 Insectary since then, being fed wholly on Scarabseid and 

 other similar grubs. It pupated and emerged in June, 1917, 

 after living for about 2^ years in the Insectary. The life- 

 cycle therefore seems to take about three to four years. 



Odontotomies assmuihi. Colonies were established in 

 artificial cashes in July but all died by about October. In
