•given oft" at intervals towards the surface where their termination is 

 marked by the small dots mentioned above. In the later stages of 

 attack, these holes become much larger and often exude a frothy Hquid 

 wiiich attracts Sarcophagid flies. 



This weevil was also found breeding in the fruits of Prunus nepalensis, 

 a wild indigenous plum whose fruits are edible when ripe. 



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

This species occurs in Assam as a serious pest of tea. It has also 

 been found in Upper Burma.

In September last year I happened to examine several stems of sann- Mr. Khare. 

 hemp which were stunted and had small curled up leaves. In all cases 

 I found some indications of an insect attack, i.e., a meagre passage cut 

 through between the pith and wood quite a long way up and down the 

 stem. In the passage at intervals very small whitish grubs were found 

 embedded in the pith — a little. Similar grubs were found in the healthy 

 stems as well, so that peculiar leaf growth could not be attributed to this 

 insect. On examining the stem from outside some black scars were 

 noticed in the axil of the leaves from about 12 to 18 inches to about 3 feet 

 above ground. If the outer bark is scraped off then distinct injury to 

 the wood is seen, thus showing that the grubs enter at such places and 

 that the eggs must have been laid in the axil. (The eggs of the weevil 

 are not found.) The height where the black scars are noticed suggests 

 that the weevils appear some time in July and remain active, depositing 

 eggs up to September. 



The grubs are about 3 mm. long, 0-5 mm. broad, whitish, fleshy, 

 tunnel between the pith and the wood, but never go right into the root. 

 The tunnelled portion is filled loosely with the frass or pellets excepting 

 a little portion above the pupal chamber wdiich is stuffed closely. The 

 grub on attaining full growth prepares a small oval chamber by cutting 

 into the wood, thus the pupal chamber is not straight along the stem, 

 but a little transverse, exteiidiiio; both in the ])ith and wood as well. 

 The grub bores a small round hole before pupating, for the emergence 

 of the weevil ; this I was led to conclude from the fact that a number 

 of small holes were found outside on the bark and", on cutting open, 

 weevils freshly come out of the pupae, were seen. 



The weevil is very small, brown, about 1-5 mm. long and has a fairly 

 long snout and long antennae ; when touched, it curls up with the snout
