made their appearance at a neighbouring Garden, Baramasia, Fati-

Remedies.— Collect and burn the caterpillars and chrysalids. 

 Mr. Burnell, by taking the prompt action he did in the matter, 

 undoubtedly saved his tea bushes from a later and what would have 

 almost certainly proved an even more serious attack. In the case of 

 sudden visitations of this nature upon tea bushes there can be little 

 doubt that a few dozen smart youngsters put on to the infested area 

 with baskets, or better still kerosene tins containing a little dilute 

 kerosene, to collect the caterpillars at work, and chrysalids if the 

 insect is pupating upon the leaves, is the quickest way of ridding the 

 attacked bushes and has the additional advantage that the danger 

 of future attacks is quickly reduced to a minimum by the insect thus 

 being prevented from reaching its egg-laying stage. 



Points in the life-history requiring further observation. 



1. When the eggs are laid. 



2. Length of time passed in the larval state. 



3. Number of generations in the year.

This insect is reported from Cawnpore, where it is a source of 

 considerable loss and trouble to the Cawnpore Woollen Mills Com- 

 pany, Limited. The Manager in sending the insect to the Museum 

 forwarded the following notes upon its life-history: — 



(S The winged insects (beetles) which we sample lay their eggs in 

 wool and woollen goods, and the resulting hairy grub, also included 

 in the specimens, is most destructive, as it appears to thrive and 

 fatten on wool and wool alone. It is chiefly at this season " [the 

 manager's letter is dated 23rd April 1902, — Ed.] that the grub 

 loses its larval character and is transformed into the beetle now sub- 

 mitted, and there are countless myriads of them in our godowns 

 and wool sheds. The grub is most in evidence in the rains and 

 cold weather. The worm-like insect we are not so clear about but 

 we believe it to be a wool eater." 



From the above excellent observations it is apparent that this 

 beetle has at least two generations in the year, the grubs of the first
