Genus EPIPSYLLA Kuwayama 
Head long, not strongly deflexed, vertex rather flat, genal 
cones very long, longer than vertex, conical and more or less 
divergent, porrect; eyes large; antennse long, slender. Thorax 
not strongly arched ; pronotum long. Forewings hyaline, 
rounded at apex, pterostigma distinct or nearly wanting. 
The general aspect of the body is similar to that of Psylla, 
but the very long genal cones easily distinguish this genus. 
Type of the genus, Epipsylla albolineata Kuwayama.
