 thought to be, they would be found also upon soft-bodied Insects, such as cater- 

 pillars and other grubs, where they would certainly be nearer to the juices which 

 they are supposed to suck. It is quite clear that farther and closer observation 

 upon both Insects and mites . .

 positive can be stated as to 

 their relations. 



The remarkable series 

 of photographs illustrating 

 this article makes the posi- 

 tion and nature of this mite- 

 chamber very clear. The 

 portrait of the bee shows, by 

 means of the white arrow, 

 the line of separation be- 

 tween the fore-body and 

 hind-body. In the longi- 

 tudinal section of the hind- 

 body on page 322, the mite 

 chamber is marked B, and 

 the black arrow points to 

 where the fore-body joins on. 

 Two other photographs show^ 

 the broad end of the hind- 

 body, first with a needle 

 inserted in the entrance to 

 the mite-chamber, and second 

 with a mite issuing from it.
