 and about the middle of hind wings, an extra discal line which makes a deep dip 

 below discal spot and then runs high up on outer margin. Beneath the discal spots 

 faint, a faint spot on middle of costa, wings a paler ash gray than above with no 

 markings except a black patch near tips of fore wings, which seems to fade out at

NOTE ON SYNONYMY.

 1906) and the synonomy should read : 



Caripeta angustiorata Walker.

 efforts for some time but without success. I read the description to 

 one of my sons and he said he had observed the larvte about a month 

 previously, but his memory was evidently at fault, as I feel perfectly 

 safe in stating that all larvae disappear by November 20th, save possi-

 things sought, I resolved to be there on schedule time when next
