 Vol. 3, p. 122 (1906). 



In this division the tympanal coverings are rounded anteriorly, not angulate — either completely 

 covering the orifices anteriorly and exposing them interiorly or the reverse, or smaller, exposing them 

 both anteriorly and interiorly ; the lateral margins of the pronotum are not convexly ampliate nor 

 medially angulate; the tegmina and wings are hyaline, sometimes maculate. 



The genera composing this division are confined to the Palasarctic, Oriental, and Malayan 

 regions and represented in Japan.
