in the light stripes, the one on each side near the subdorsal region with 

 the black patches on the posterior part of joints as before, the patch on 

 joint 5 filling the whole stripe, the next a little pale in the centre, those 

 back of joint 6 a little darker than the anterior part of the joint in the
