the Relative Edibility of Insects. oT 
Hemiptera as a whole give more irregular results than 
other families, and further experiments are much needed. 
The odour that to us seems so very unpleasant does not 
appear to be considered a distasteful quality by the 
monkeys; moreover species were refused that had no 
perceptible odour. In one family may be found typically 
aposematic but comparatively odourless species, and 
extremely odoriferous but highly procryptic species. 
Comparison between the two Monkeys. 
M, seems to have been somewhat less severe in his

judgments than M,, as is shown by considering the fifty- 
five species offered to both. Of these, forty were put in 
the same class, plus or minus, by each monkey. But nine

others classed as plus by M, were put in the minus class by 
M,, and only three classed as minus by M, were put in the 
plus class by M, (see ring diagram below). 
It is of some value to the results of these experiments 
that the monkeys should have agreed in 4% cases. In 
quite a number of cases the agreement was exact; these are 
listed below.
