Out of the whole available anthophilous insect fauna of (for 
the time of our observations) 17,30 6 individuals, 6,156 went 
to Class B', and 1,482 to the massed flowers of Class A, which 
we may here for brevity call Class A'. The species of plants 
obtained attention as in Tables IX and X, B' obtained many 
more of the desirable insects (see p. 315) than A', and very 
much fewer of the injurious, which could find but small 
encouragement where the honey is hidden (see Table XI). 
Class B' is found by our observations to fall very markedly 
into two divisions : one division contains the plants whose 
flowers belong to the rose-purple-lilac-blue series, the other
