of the Genus Teracolus, Swains. .001 



80. Teracolus prceclarus. 

 Teracolus praclarus, Butler, P. Z. S. 1885, p. 700, pi. xlvii. fig. 7. 



Somaliland. 



This beautiful species is evidently a link between T. pholoe 

 and T. zoe, although the latter is in many respects more 

 nearly related to the T. halimede group. It is probable that 

 other species of the T. celimene type still remain to bo dis- 

 covered. T. prczclarus appears to be a dry-season form. 



81. Teracolus zoe.

 Mabille, in Grand. Madag. pi. xl. tigs. 3-5. 



Madagascar. 



In the ash-grey base and black veins to the primaries and 

 orange costal stripe to the secondaries this species approaches 

 T. ho. In other respects it is nearer to T. prceclarus. 



82. Teracolus leo. 



Anthocharis leo, Butler, Ann. & Mag. Nat. Hist. ser. 3. vol. xvi. p 3SJ7 

 (1805). 



Appears to be confined to North-eastern Africa, from the 

 White Nile to Somaliland, and southward as far as Kilima- 

 njaro. 



It is readily distinguishable from T. halimede by the orange 

 patch on the primaries being restricted to below the first 

 median branch and the outer dusky border only represented, 

 even in the wet-season examples, by spots. The type of the 

 species is, in my opinion, an intermediate form between the 

 wet and dry phases. I have not yet seen what I should 

 regard as an undoubted dry-season form, unless it be repre- 

 sented by a small example from Mr. Druce's collection (Gr. & 

 S. coll.) in which the orange is carried a little above the first 

 median branch, the base somewhat glistening and white, 

 and the apical markings weak as in typical T. leo. This 

 specimen is without locality.
