TINEINA [ooLF.opiior.A 



repose the antennae are porrected straight forward, instead of 

 being thrown back as usual. The genus is closely allied to 

 Batirached/ra, and probably a development of it. The internal 

 evolution of the genus is obscure, but probably the Juncus- 

 feeding species arc the most ancestral (several exotic species of 

 Batreuihedra also feed on seeds of Juncus), giving rise to two 

 main lines of development, represented by the unicolorous and 

 vein marked groups respectively.
