 of legs with apical two thirds yellowish white. 



Third Nymphal Stage. — Length 1.3 mm. Body ovate, head tri- 

 angular, eyes lateral, prominent, granular. Mesothorax longest, 

 metathorax shortest of thoracic segments. Sides of thorax rounded, 

 broadening posteriorly. Mesothorax broadest. Abdomen rounded,
