 As pointed out by Snellen," the two sexes of Zeller\s genus Seto- 

 morpha have different venation, the males lacking vein 4 in both 



anterior and posterior wings 



while the females possess this 

 vein in both wings. 



Though 1 called Doctor Dietz\s 

 attention to this fact, he has in 

 his recent paper* separated the 

 two sexes generically and erected 

 a new genus Semiota on the m?i\Q 

 characters; and though he has 

 examined Zeller's type of opero- 

 «dhh which is, as he says, a fe- 

 male, he did not make out its different venation and included it in his 

 new genus. This genus Semiota Dietz with inamoenella as type must 

 consequently fall. 



Zeller .says,^ " die beiden Geschlechter auch der americanischen Arten 

 m Grosse sehr verschieden zu sein scheinen,'^ but nevertheless he makes 

 one species for the male and another for the female. Zeller evidently
