This species may be recognized by the great thickness of the waxy covering. 

 There are thicker cushions of wax on the four stigmatic areas, and a prominent 

 dorsal hump terminating — above the anterior extremity of the insect— in an 

 incurved process {d), but the test is not divided into distinct plaques. The 

 valves of the anal operculum are carried at the extremity of an elongate, 

 densely chitinous process {e). The "wax is comparatively soft, and of a creamy 

 or greasy consistency. Overall length of example under observation 5 mm. ; 

 breadth 4 mm. Well-developed examples from India may attain a length of 

 12 mm.
