of the Genus Teracolns, tiwatns. "/)7 



any other species of the group, this butterfly diffrrs from all 

 in the imich greater restriction of the ochrcous colouring on 

 the primaries of the male (which commences beyond tin-, end 

 of the cell), in the entirely different coloration of the under 

 surface, the primaries being saffron -yellow on basal two fifths, 

 very pale creamy yellow on the disk, and with the dark 

 bands golden olive or yellow-brown, the two outer bands on 

 the secondaries near together and arched rather than angu- 

 lated (as in T. vesta as compared with T. mutans). From all 

 the species excepting T. Hanningtoni it differs in the minute 

 discocellular spot on the primaries. Only the wet-season 

 form is known at present either of T. Hanningtoni or of this 

 species.

It is closely related to the preceding species and especially 

 to T. Hanningtoni^ but its superior size, bright uniform yellow 

 colouring, black-veined primaries, less banded upper surface 

 of secondaries, and lack of a subbasal band on the under 

 surface of these wings, have saved its being regarded as a 

 variety of T. vesta. These differences, though perhaps not 

 greater than exist between T. amelia and T. mutatis, are more 

 readily grasped without effort. 



The seasonal differences are well defined, the wet-season 

 phase having the chief markings below smoky brown, partly 

 veined with saffron-yellow ; the intermediate form has these 

 markings redder and with well-defined veining ; the dry 

 phase has them almost wholly bright reddish orange. At 

 Aden all three types occur together as mere variations.
