A. sc, scape; fl, flagellum; 1, 2, &c., number of joints: af, antennary fos- 
8a, or hollow; ¢r, trachea; 7, soft membrane; wh, webbed hairs; lm, levator 
muscle; dm, depressor muscle. 
B, small portion of flagellum (magnified 60 times); n, nerve; a, articula- 
tion of joint. 
“These hairs, standing above the general surface, constitute 
the antennz marvelous touch organs; and as they are distributed 
all round each joint, the worker-bee in a blossom cup, or with its 
head thrust into a cell in the darkness of the hive, is, by their 
means, as able accurately to determine as though she saw; while 
the queen, whose antenna is made after the same model, can per- 
fectly distinguish the condition of every part of the cell into 
which her head may be thrust. The last joint, which is flattened 
‘on one side, near the end, is more thickly studded, and here the 
hairs are uniformly bent towards the axis of the whole organ. 
No one could have watched bees without discovering that, by the 
antenna, intercommunication is accomplished ; but for this pur- 
pose front and side hairs alone are required; and the drone, 
unlike the queen and worker, very suggestively, has no others, 
since the condition of the cells is no part of his care, if only the 
larder be well furnished.’’ (Cheshire.)
