 and punctures are congregated on the lower third, the upper 

 two-thirds carrying several secondary tubercles or punctures 

 (text-fig. 11, b). Pd. 1 at about the same height as adfr. 1 ; 

 puncture pd. la closely approximated to pd. 1 and medial; 

 pd. 2 medio-dorsal to pd. 1 below adfr. 2 ; puncture pd. la 

 latero-dorsal to pd. 2 and placed far lateral, about dorsal 

 to ad. 2. 



(b) Antero-dorsal Region. — Ad. 1 at about the same 

 height as puncture f .a, medio-dorsal to the first ocellus ; 

 ad. 2 and ad. 3 high, closely approximated; ad. 3 about 

 level with pd. 1 ; ad. 2 about midway between ad. 3 and 

 pd. 1, slightly below a line connecting these two. Puncture 

 ad. 2a apparently absent. 



(c) Lateral Region. — Only puncture 1. la could be seen, 

 no seta 1. 1. Puncture at about the same height as adfr. 2.
