TINEINA 



[COLEOPHORA 



repose the antennae are porrected straiglit forwai'd, instead of 

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

 Bati'achedra, and pi'obably a development of it. The internal 

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

 feeding species are the most ancestral (several exotic species of 

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

 main lines of development, represented by the unicoloroiis and 

 vein-marked groups respectively.
