in VII the two median dots are united by a slender black line, and there is a pair 
of lateral dots, right and left ; in VII (i VIII) the median line is of uniform 
width, extending from about the centre to the lower margin, and to its left side 
there is a single dot ; in VIII the median line alone is visible, both lateral dots 
having disappeared ; while in IX there is no continuous median line, but merely 
two black spots, one at the extreme dorsal and the other at the extreme ventral 
side of the clypeus. It will be noticed that Types VII — VIII approximate to 
Type IV in so far as the black stripe begins at about the middle of the clypeus 
and extends right down to the ventral margin.
