 whitish spot upon its hinder end ; the mesonotal, metanotal, and 

 abdominal terga w-ere, like the head, pale drab relieved by sym-

 between the prothorax and the head in front of it and of the 

 tergal plates behind it was disruptive, the colour-continuity of the 

 upper surface being destroyed. The fore legs, folded beneath the 

 prothorax, were indistinguishal)le, and the remaining two pairs

 femur was paler than the distal end ; the tibia was marked with 

 a median and a distal dark ring, and the end of the tarsus was 

 darker than its proximal portion. The optical eflect of this 

 alternate banding with dark and light of the distal half of the 

 legs was discontinuity of surface, the light areas being obliterated
