{Undetermined Ctirculionid.) 



This weevil was found at Puaa, the larva boring in sann-hemp stems 

 in the field, 15th August 1916, the adults emerging in the middle of Sep- 

 tember 1916. 



The larva bores the central part of the stem and when full-grown 

 forms a sort of pupal cell at the end of its burrow just below the bark 

 of the stem. It is doubtful how far it is a pest. 



{Undetermined Cmcidionid.) 

 The weevil was found at Abbottabad, at the beginning of June 1916. 

 The adults occurred in numbers on apple, rose, Rubus spp. and thistles, 

 eating the leaves. 



Dijscenis fletcheri, Mshll. M8.* (Plate 6.) 

 This weevil was found at Shillong, the larva boring into apple fruits 

 in June 1918. It is a reddish-brown species with scattered patches or 

 dots of greyish scales. It is rather larger than the next species but 

 attacks apple fruits in exactly the same way, but pupation seems to take 

 place sometimes outside of the fruit. The egg is about 1 mm. in diameter 

 and rather dull-brown in colour. The larva seems quite similar to that 

 of the next species. The adults seem long-lived, as an individual caught 

 at Shillong about l-5th June, and brought to Pusa, lived in the insectary 

 imtil 15th October. 



Dr. Marshall has identified this as a new species of Dyscerus. 



Dyscenis maligmis, Mshll. MS.f (Plate 7.) 

 This vveevil was found at Shillong in June 1918. It is brownish- 

 black with a conspicuous grey patch on posterior portion of elytra. The 

 adult weevils feed on apple fruits, eating small patches into them, and 

 oviposit in excavations along the edge of such patches. The eggs are 

 large for the size of the insect, about 1-25 mm. in diameter and pearl- 

 white in colour. The grub bores about in the interior of the fruit and 

 damages it considerably. Pupation takes place inside the attacked 

 fruits which in the initial stages of attack are externally scarcely dis- 

 tinguishable from healthy fruits, but the invariable presence of a number 

 of small whitish dots on the surface of the infested fruits marks these as 

 attacked. These small dots are really holes through which the tunnejs 

 of the grubs communicate ^Nith the open air, and as a rule these 

 tunnels originate at the apical end of the fruit, somewhere near the 

 flower scar, whence they ramify throughout the interior, branches being
