Length oj antenna in relation to length 



of hind leg : (i) Subequal or antenna 



shorter. (2) Antenna longer. 1 1 1 2 2 1 



Relative length of yd and terminal 

 antennal segments : (1) Segment III 

 less than 1 -5 times as long ; some- 

 times both subequal. (2) Segment 

 III usually more than 1-5 times as 



the terminal. 1 1 1 1 2 



Width of segment III related to its 

 length : (1) Length usually 5-3 times 

 the width or less. (2) Length more 



than 5-3 times the width. 1 1 1 1 2 1 



Width of preterminal antennal segment 

 to its length : (1) Length usually less 

 than 3-3 times the width. (2) Length 



33 times the width, or more. 1&21 1 2 2 2 



Antennal setae : (1) Comparatively 

 short ; less than twice as long as 

 body setae. (2) Long ; twice as 



long as body setae or more. 1 & 2 1 1 1 2 1

setae : (1) Absent. (2) Present. 2 2 2 2 1 2 



If present : (1) Only on segment X. 

 (2) Few on segments III to X, but 

 other setae more numerous. (3) On 

 segments III to X forming the 



majority of the antennal setae. 1 1 1 2 NC 3
