Note. — This is a very distinct species, recognisable by the 

 bluish grey dusted spots on the shoulder ; the similarly coloured 

 band on the posterior margin of the thoracic dorsum, and the first 

 abdominal segment tinged with the same colour also. The third 

 fore tarsal joint being widened is also a specific distinction, and 

 noticeable when specimens of grisescens and indicum are placed 

 side by side.
