P. echidna , Guer., is a common 
form in the Western Ghauts and 
Nilgiris. Hispa (Phidodonta) modesta, 
We., has been bred in sugarcane; 
its life has been fully described 
(Mem. Agri. Dept. Ent.), as has also 
that of Hispa cenescens , By. This 
last is a very important pest in rice¬ 
growing tracts and may be distingui¬ 
shed by the form and position of the 
pro thoracic spines, the small tooth 
at the lower edge of the basal an¬ 
tennal joints, the absence of spines 
on the antennse above and the me¬ 
tallic black-green colour. The dis¬ 
crimination of Hispids is not difficult if attention be paid to such points, 
but the student may be cautioned against hasty identification without 
very careful examination.
