highly developed, as indeed might be expected when we consider the 
part they have played in the development of flowers. While these 
experiments seem to show that blue is the bee's favorite color, this does 
not accord with Albert Miiller's experience in nature, nor -with the 
general experience of apiarians, who, if asked, would very generally 
agree that bees show a preference for white flowers. 
Touch. — The sense of touch is supposed to reside chiefly in theantennaB 
: or feelers, though it requires but the simplest observation to show that 
with soft-bodied insects the sense resides in any portion of the body, 
very much as it does in other animals. In short, this is the one sense

Hauser) ; D, sensory organs of Termes flavipes; a, tibial auditory organ ; c, enlargement of same ; 6,

Myrmica ruginodis; c, cork-shaped organs ; s, outer sac ; f, tube ; w, posterior chamber (after Lubbock) ; 
K, longitudinal section through portion of llagellum of antenna? of worker bee, showing sensory 
hairs and supposed olfactory organs (after Cheshire). All very greatly enlarged. 
which, in its manifestations, may be conceded to resemble our own. 
Yet it is evidently more specialized in the maxillary and labial palpi 
and the tongue than in the antennae in most insects. 
Taste. — Very little can be positively proved as to the sense of taste 
in insects. Its existence may be confidently predicated from the acute 
discrimination which most monophagous species exercise in the choice 
of their food, and its location maybe assumed to be the mouth or some 
of the special trophial organs which have no counterpart among verte- 
brates. Indeed, certain pits in the epipharynx of many mandibulate
