This is a small genus containing six described species, three of which come 

 from New Mexico, two from Ceylon and India, and one from Australia. In 

 the original description, Maskell placed our species doubtfully in the genus 

 Eriocliiton. 



The members of this genus, like those of the genus Inglisia, are enclosed 

 in a glassy test, which differs in being convex, but not cone-shaped, not 

 divided at all, but rough or covered with protuberances. A more or less 

 hemispherical scale, covered with dorsal knobs. " Legs and antennae well 

 developed. Stigmatic clefts well defined; each cleft with a single, very 

 long pointed, stigmatic spine. Margin of body with a fringe of stout conical 

 spines, usually in two or more rows. Other characters as in Lecanium." 

 (Green). 



Differs from Inglisia and Ctenochiton in having the body of the advdt 

 female shrinking up, and allowing for a cavity for the eggs and larvae.
