20 TERACOLUS. 



Very nearly allied to T. puellaris and T. vesfalis, of which it is the African repre- 

 sentative. It is distinguished, however, by the more pointed primaries and by the 

 black marginal border on the secondaries being more broken and relieved by white 

 spots. 



Male. — With the black hind-marginal border on the primaries terminating in an 

 extra spot of white near the posterior angle ; costa more heavily marked with black, 

 the discoidal spot at the end of the cell being very clearly defined. The grey at the 

 base of the primaries is also much stronger in colour and crosses the wing obliquely 

 from the centre of the cell to the inner margin. 



Secondaries with the black marginal border entirely broken by a row of white 

 spots varying somewhat in size and disappearing in some specimens, above the second 

 discoidal nervule. A distinct grey streak is visible close to the base of the wing. 



Underside.— Frimaries with the costal margin, apex and hind-margin bright 

 yellow, as far as the first discoidal nervule. Crossing the apex is a faint row of 

 reddish-brown spots, which unite with three black spots near the hind-margin as in 

 T. ves/alis, but they are not so pronounced ; and the lowest one, above the sub-median 

 nervure, is nearly obsolete. The discoidal spot is orange outlined with black. The 

 secondaries are bright yellow, with a sub-marginal row of irregular reddish-brown 

 spots, commencing from the costa and becoming nearly obsolete above the first dis- 

 coidal nervule ; there is also a minute orange spot at the end of the cell. Expanse 

 r5 inch. 



Female. — Primaries very similar to those of the male, but with the black 

 markings browner, base of wing greyish-brown. Secondaries with the brown 

 marginal border entirely broken by a row of white spots. 



Underside.— Vale yellow, the primaries having a sub-marginal row of reddish- 

 brown spots from the costa to above the sub-median nervure, the orange discoidal 

 spot larger secondaries similar to those of the male, the sub-marginal row of reddish- 

 brown spots being more irregular. Expanse 2 inches. 



This species appears to be confined to East Africa, where it ranges from the 

 district of Mombasa and Toita to Somali Land. Specimens seem to be rather rare in 

 collections, and I have therefore not had a good series to work from. They are all 

 " wet-season " examples, two males in Mr. Jackson's collection being very dark, the 

 marginal border on the secondaries having no white spots {cf. plate 7, fig. Id), but 

 these are present in a female in Mr. Eothschild's collection, which represents the 

 " dry-season " form.
