22 TERACOLUS. 



Fkma],k. — Creamy white, the dark marginal borders browner Ihan in the male; 

 the sub-apical row of spots deeper yellow rather than golden yellow, and a distinct 

 circular indentation at the posterior angle of creamy white. At the end of the 

 discoidal cell is a very distinct brown spot. Secondaries creamy white, the base being 

 dusted with greyish-black, the nervules terminating on the hind-margin in distinct 

 brown spots, which are much more emphasised than in the male. 



Underside. — lluther a deeper yellow on the secondaries, the dark markings being 

 similar to those of the male. Expanse 2 inches. 



"Diir-SEAsoN " FORM. The male is distinguished by a very plainly indicated black 

 discoidal s])ot at the end of the cell. The apical patch is much brighter golden 

 yellow, and the white fringe below the second median nervule is more pronounced. 

 The secondaries show no black spots at the end of the nervules. 



Underside. — Primaries white with the characteristic spots smaller. Secondaries 

 sandy yellowish, the orange costal line terminating in a dark s^jot. Expanse 2 inches 



Fkmale of the "dry-season" form. Shows a somewhat striking difference. Both 

 wings are pale yellow, the apex reddish buff, relieved by three deeper yellowish spots. 

 A transverse baud of dark brown crosses towards the hind-marginal border and is 

 connected by a narrow line with the darker brown border of the inner margin. There 

 is also the characteristic yellow posterior spot, as well as the dark spot at the end of 

 the discoidal cell. 



The secondaries are nearly uniform, but show two reddish-brown spots between 

 the costal and sub-costal nervures. 



Underside. — Central area of the primaries pale yellow, the apex and secondaries 

 being sandy bufi", while the three dark marginal spots on the primaries are much 

 reduced. Expanse 2 inches. 



In another extreme "dry-season" (form Fig. If) considerable differences are exhibited 

 from the one described above. The brown markings are much reduced in extent, and 

 the yellowish-white of the primaries is more extended. Thus the white of the hind- 

 margin is continued up towards the costa, so that it sej^arates a pale reddish-brown 

 apex from the dark brown inner baud; the latter is not continued to a junction with 

 tlie dark inner margin, as in the specimen previously described, but is represented by 

 a couple of brown spots. The discoidal spot is strongly in evidence, as are also the 

 two brown spots near the apical portion of the secondaries. The underside is very 

 similar to that of fig. le, but is even more sandy yellow, the sub-marginal row of 

 spots on the primaries being more distinct. Expanse 2 inches.
