CYRTOTRACHELUS LONGIJPES. 197 

Mr. Gregson states in his note that shady places under thick 
growth are preferred to others. By this I understand him to 
mean thick uxdergrowth in moist places, not high forest. In 
such places the shoots undoubtedly come up thickly and are 
most succulent, and as such are doubtless preferred by the beetles 
for egg-laying. 
Protection and Remedies. 
In the case of plantations the most obvious remedy is to 
collect the female beetles when egg-laying ; a surer method, 
dig up the pupal cases and burn them. A better remedy, how- 
ever, and one which would be practicable over larger areas would 
be to collect all the fallen and evidently attacked tops, each of 
which contains, as we have seen, a larva, and burn them. This 
done carefully would do a great deal towards stamping out the 
attack. 
Points tn the life history requiring further observation, 
Owing to Mr. Gregson’s excellent observations, these, as far 
as is at present known, would appear to be few. 
1. The number of eggs laid by the @. This is a very 
important point, and would be easily discoverable 
were some beetles obtained as soon as they issued 
in June and kept in a box with fresh bamboo 
shoots, each shoot upon which eggs had been laid 
j being removed. 
2. What other species, if any, of bamboo are attacked 
by this beetle.
