cJ ?. A red band on liindwing, the patches composing the band either large and 

 contignous {xenarclii(>i) or smaller and separate {erklani'is). 



There is a broad-banded male in coll. Godman and another in coll. Charles 

 Oberthiir, and two females in coll. Hewitson (Brit. Mus.). Narrow banded speci- 

 mens appear to occur more often. In a male in coll. Hewitson the red spots are 

 pro.ximally more or less extended grey-blue ; a similar transition to the next form 

 is in coll. Standinger. 



The red-banded form is known only from Eastern Mexico, where it occurs 

 together with the next, being much the rarer of the two.
