We have already said that, over and above their high intelligence,bees are remarkable for having certain parts of their body speciallymodified in connection with the acquiring of honey and pollen. Wemust therefore further consider the structures concerned in effectingthis end, viz., the suctorial apparatus and the apparatus for collectingpollen. The suctorial apparatus is in most bees developed in very greatperfection. In many (Figs. 13-15) the proboscis is of considerable. Fig. 16.—Head op Anthophora Eetusa ; ten limes enlarged.

The maxilloe (K) and part of the labial palpi (T) are modi-fied into flat, leaf-like, linear processes, which are arranged around thetongue (R), and thus complete the suctorial proboscis. While, there-fore, the suctorial apparatus of the butterfly consists simply of a coil-ing or suctorial tongue, it must be noted that in the bee other partsare concerned in the formation of the tubular sucking apparatus. Inmany bees, besides, the tip of the tongue is peculiarly modified, soas to enable the insect to taste the honey before beginning to col-lect it, an a
