HABITAT. Washington. 



The type is in Mr. Neumoegen's collection. In proposing the genus 

 Euthyatira for the two species here associated, I wish to express iny con- 

 viction that the American species heretofore referred to Thyatira are 

 not at all congeneric with batis, the type of the genus. There is a cer- 

 tain similarity in the type of maculatiou, but none in wing form or in 

 other details.
