presume all wasps clean these organs by passing them between 

 their jaws, much as a child cleans his fingers after eating 

 candy, except here lips take the place of jaws. We can hardly 

 conceive of a better arrangement for this purpose, a delicate 

 brush and a soft membrane ; even better than the housewife 

 armed with soft brush and a silk kerchief, for this antenna 

 cleaner just fits the organs to be dusted. We have seen the 

 important function of the antenna, as most delicate touch-

 the tibia opposite the spur and also the brush of rather spinous 

 hairs on the tarsus (Fig. 66) are of use to brush the hairs, eyes 

 and face, as may be seen by careful observation. 



The claws and pulvilli — the delicate gland between the 

 claws — are well marked on all the feet of bees. The claws 

 (Fig. 67, cl) are toothed, and are very useful in walking up 

 wooden or other rough surfaces (Fig. 68, B), as they are used 

 just as a squirrel uses its claws in climbing a tree. These
