46 AUSTRALASIAN 
at the end of the tibia or long joint of the leg) on their posterior 
legs, and as to their wings, “they have three cubital or sub- 
costal cells—the second row from the costal or anterior edge— 
on the front or primary wings.” Here we cannot help 
remarking how wonderful are those minute rules of organic 
structure. Who that examined for the first time the wing of 
a bee, and compared it with that of any other insect of the 
same order, would imagine that the differences in the sub- 
divisions of the membrane, which have all the appearances 
of chance formation, and which are probably not precisely the 
same in any two examples, are yet so characteristic in their 
arrangement as to afford an easy means of distinguishing the

genus to which the insect belongs! Professor Cook gives the 
following further details as marks of this whole genus :— 
“On the inner side of the posterior basal tarsus, opposite the pollen 
baskets, in the neuters or workers, are rows of hair (Fig. 15) which 
are probably used in collecting pollen. In the males, which do no 
work except to fertilise the queens, the large compound eyes meet 
above, crowding the three simple eyes below, while in the workers and 
queens the simple eyes, called ocelli, are above, and the compound 
eyes wide apart. The drones and queens have weak jaws, with a 
rudimentary tooth, short tongues, and no pollen baskets, though they 
have the broad tibia and wide basal tarsus.” 
NERVOUS SYSTEM. 
Coming now to the special anatomy and physiology of the 
Apis mellifica, it may be well, in the first place, to show the 
general arrangement of the nervous system as depicted by Mr. 
F. R. Cheshire in his admirable “ Diagrams on the Anatomy and
