 lar, a dot and streak on patagia ; abdomen with basal segmental 

 bands, widening on the sides, the last two segments with dor- 

 sal black patches. Wings with brown lines, appearing numer- 

 ous ; a dot on costa and vein 1 near base ; two dots on inner

 an inverted looped line below ; reniform a pair of bars, con- 

 stricted, filled with darker yellow, the inner bar touching the 

 looped line below ; outer line curved, running to inner margin 

 at middle, stout from costa to vein 5, fine and dentate on 3 

 and 4, slightly dislocated on 2, along which runs a stout line 

 to termen; an excurved branch at vein 5, denticulate, sub- 

 parallel and reaching inner margin at its outer fourth ; a sub- 

 terminal denticulate line, not attaining costa and ending at 

 vein 2 ; veins 5, 6, and 7 dark-lined between the outer and 

 subterminal lines ; a terminal line, dentate on the veins ; fringe 

 dark, submetallic.

 Uitolugt, Georgetown. British Guiana, January, 1915 (H. W. 

 B. Moore), bred from larv?e on young leaves of cacao. Other 

 specimens are before me from Cayenne, French Guiana, Feb-
