Insects in Great Britain. 
615 
Out of the whole available anthophilous fauna of (for the time of our 
observations) 17,306 individuals, 1,429 went to Class B. The species ob- 
tained attention as in Table XXXIII. In summer among the visitors were 
more long-tongued Lepidoptera than the class’s share, and more Syrphidae 
(see Table XXXVI) ; in autumn among the visitors were more Bombi and 
more Coleoptera because Bombus went very freely to Thymus and Calluna } 
and Meligethes to Raphanus Rciphanistrum. As shown in Table XXXIV, the 
summer visitors were of a higher type than the spring and autumn visitors. 
In Tables XXXVII and XXXVIII the flowers of this class are divided 
according to their colour, and it is easily seen that the long-tongued Lepi- 
doptera showed a distinct preference for flowers with a certain amount of 
blue in them, and the Bombi for rose-purple, and Apis for white and rose- 
purple. One yellow flower, viz. Raphanus Raphauistrum , drew so many 
individuals of Meligethes that the percentages for yellow are biased and the 
percentages for green are founded on too small figures for discussion of them 
to be possible. 
We do not find Class B, by visitors, breaking into two halves as Class B' 
did, yellow and white on one side, blue-lilac-purple and rose on the other, 
nor do we find the visitors visiting the colours as we found them visiting 
Classes H and F. 
Class B was found to attract nine species of the butterflies, sixteen 
large moths, six small moths including Eriocephala ; of Hymenoptera, 
Apis, five species of Bombi, two of Andrena, two of Vespa, of Formica, of 
Odynerus, of Allantus, of four species of Parasitic Hymenoptera ; among Dip- 
tera, in the Syrphidae of Rhingia campestris, Volucella bombylans, Leuco- 
zonia lucorum, Helophilus, three species of Eristalis, one Chrysogaster, 
seven species of Syrphus, Syritta, Ascia, four species of Platychirus, 
and two of Melanostoma ; in Empidae of seven species of Empis including 
E. tessellata, of one Rhamphomyia and of one Clinoceira ; Siphona genicu- 
lata was the only Tachinid attracted ; among Muscids the class attracted 
two Calliphorae, one Lucilia, one Pollenia and one Stomoxys, of Cynomyii- 
dae one species, of Anthomyiids eighteen species including Drymia hamata, 
of Scatophagids one species, and of other orders of flies eleven species ; of 
Coleoptera six species, one of Hemiptera, one of Trichoptera, and of 
Thrysanoptera one.
