TERACOLUS. 27 



cannot be considered absolutely typical ; in fact, I look upon them as a distinct race 

 which may be called T. feitensis, for they have the white spot on the primaries, 

 between the second and third discoidal nervules, more or less pronounced. 



The British Museum has likewise several specimens of Teracoli, said to be from 

 Senegambia, from the Salvin-Godman collection ; these were formerly in the 

 collection of Mr. Herbert Druce. Two of these appear to be true T. eris, but 

 whether they came from Senegambia has yet to be determined.

This species is distinguished at a glance by the yellow streak on the underside 

 between the sub-median and first median nervules of the secondaries. 



Male. — With the white central area on the primaries much reduced, the hind 

 and inner marginal borders being broader and more heavily marked than in T. 

 iohnstoni and T. eris; the apical patch larger, with a brown violaceous gloss ; the 

 ground-colour relieved by five ovate streaks of " old gold," much more pronounced 

 than in the foregoing species. There is the usual white spot between the discal 

 nervules, but the white marginal fringe at the posterior angle is not so plainly 

 indicated. Secondaries with a very broad, black, curved, costal border extending 

 along the second and first sub-costal nervules, the border showing an indication to 

 form a discal band. Each of the nervules terminates in very pronounced black spots. 



Underside. — Similar in markings to T. johnstovi and T. eris, the general colour 

 being pale yellow, the primaries having the characteristic post-median spots more 

 heavily marked than in the above-named species, the nervules terminating on both
