amount of glucose may have been added, or that the re-sugared 
material may have been insufficiently dried. 
It is to be noted that both the bamboo attacked and that visibly 
sampled by the beetles contained starch. The other pieces of 
bamboo included in the jars and apparently untouched were as 
follows:—In jar B.—Untreated pieces from two thinner- 
stemmed bamboos, having no starch and very little glucose. 
It is not surprising that these did not prove attractive. In 
jar A.—(1) Untreated, thin-stemmed, no starch and little sugar; 
(2) untreated, rather thin-stemmed, no starch, plenty of glucose; 
(3) thin-stemmed, no starch, originally very little sugar, but 
treated by soaking in glucose-solution ; (4) thick-stemmed, soaked 
in Victoria regia tank, starch present. 
The attack of starch-containing material and the absence of any 
boring in untreated bamboo, in which there was plenty of glucose 
but no starch, may indicate a preference for a diet containing 
starch. It is possible, however, that the sugary but starchless 
specimen was rejected because it was from a_thin-stemmed 
bamboo. The fact that all the specimens definitely attacked, as 
well as those in which small borings were begun, were from the 
same thick-stemmed bamboo, may have some significance. 
Perhaps thick-stemmed material is chosen first for a trial, if at 
hand, or preference may be given to certain species of bamboo. 
These later experiments scarcely help towards a general con- 
clusion. The tentative boring of treated bamboo, however, is 
confirmed, and, as this was more than a mere tasting of the
