It does not seem likely that these genera and Machimia are con- 

 generic, but until the genitalia of the genotypes are carefully studied 

 we must accept Meyrick's classification. 



Busck^'^ and Walsingham ^^ have correctly separated Psilocorsis 

 from Ci^ptolechia and Machimia^ on the distance of veins 2, 3, and 4 

 from each other, but have synonymized the latter two. As stated 

 above, I follow Meyrick in the separation of G infptolecliia and Mach- 

 imia^ his contention being borne out by genitalic as well as palpal 

 characters. Of the American species formerly included in this genus 

 all but teiitoriferella are referable to other genera.
