36 THE ANATOMY OF THE HONEY BEE. the body. It is again specially developed on the palpuslike append- ages of the sting. (See figs. 36 and 37, StnPlp.) Sections of a bee's antenna show that there are on its surface a great number of minute structures of sev- eral different kinds, though all apparently are to be re- garded as modified hairs, which are undoubtedly the sense organs. Xow the diffi- culty arises of deciding which of these to assign to the sense of touch and which to the sense of smell. Different au- thors have made such differ- ent interpretations of the sense organs of insects that the student attempting to get information on the subject from books must soon be dis- couraged by their conflicting statements. But- it must be realized that only intelligent guessing is possible where several senses are located on the same part. In the case of the bee some authors have ascribed even a third sense, that of hearing, to the an- tenna?, but there is little evi- dence that bees possess the power of hearing. The senses of taste and touch are pos- sessed by the month parts,

Thus, the organs of sight are apparently the only ones that can not be con- fused with some other sense. The best account of the antennal sense organs of the bee is that of Schiemenz (1883), whose drawings are here reproduced (fig. 12) and whose text is the basis of the following descriptions. The organs consist, as before stated, of modified hairs and their basal
