Mr. E. Ernest Green on 



joints are subequal in length, but gradually diminisli in 



thickness. The ap- 

 pendages are finely 

 setose, and there 

 are a few stout 

 spines on the basal 

 and following six 

 or seven joints. 



The antennaj have 

 undergone very 

 little change. They 

 still contain fifteen 

 joints ; but the 

 second isvery small 

 and sunk into the 

 apex of the large 

 basal piece, which 

 bears several stout 

 spines. 



There is an im- 

 portant change in 

 the structure of the 

 'legs, three joints 

 being now appa- 

 rent in the tarsi ; 

 the second joint, 

 is, however, very 

 small, and firmly 

 fixed to the pre- 

 ceding one, the line 

 of separation being 

 rather inconspicu- 

 ous. The femora 

 are distinctly chan- 

 nelled for the re- 

 ception of the tibiae. 

 There is no pad 

 between the claws. 



The mouth parts, 

 as far as can be 

 seen without dis- 

 section, are as de- 

 scribed by Prof. 

 Westwood ; the 

 maxillj© are perhaps rather longer and more falcate.
