 The small figure shows the natural >i/e. (Original.) 



Distribution. — Bangalore, Coimbatore, Madras- Probably wher- 

 ever mangoes are grown in Southern India. Usually in June and 



July. 



Lifehistory. Not fully worked out. Eggs are probably laid in 

 the young fruit into which tin- newly-hatched grub bores, taking 

 up its position inside the embryo mango-stone whose interior it 

 devours. When full-fed, the grub pupates inside the stone and the 

 weevil bores its way out. Length of life-cycle not known ; probabl] 

 ne brood annually, the beetles surviving as adult- until the 

 next mango-season. A specimen <>t the adult beetle was found on 

 o-palm in Chittur in February 1908. 



Foodplant. Mango (chief!) on sweet varieties). No alternative 

 foodplant is known. 



Status. Not .1 serious pest as a rule. A small proportion ot fruit 

 is spoiled by the weevils boring out of the fruit on exit from pupa.
