clean, to enable it to walk up glass or other smooth substances, it is not 

 contented, like the fly, with brushing them one on another, but will, 

 like a spider, as first recorded by me, go over the foot with its jaws, 

 mumbling off every bit of dust, a process which Swammerdarn mistook 

 for chewing the cud. 



" MUSCLES OF THE LEGS AND FEET. Beginning with the haunch, 

 Straus-Durckheim describes in the cockchafer four flexor muscles in the 

 fore leg, three in the mid leg, and five in the hind leg, without men* 

 tioning two others attached to the latter, which he supposes rather to 

 be pertractors of the. abdomen. Opposed to these are the extensor 

 muscles of the haunch, one strong one in the fore leg ; a short one and 

 a long one in the mid leg ; and three in the hind leg. Besides these, 

 there are a flexor and an extensor to that which I have called the third 

 piece of the haunch.
