336 Miss E. M. Sharpe on new East- African Butterflies. 



Fam. Pieridae. 



Teracolus bifasciatus, sp. n. 



Similar to T. eione {cf. Butler, P. Z. S. 1876, p. 144), but 

 having the orange patch divided in two by a series of con- 

 fluent black spots, increasing in size to the last but one. It 

 differs also in the second black band on the hind wing, which 

 encloses a very distinct patch of white near the upper hind 

 margin of the latter. T. bifasciatus has one black spot at the 

 end of the cell. There are several other minor differences, 

 the present species having more orange markings than 

 T. eione, and the tint of the under wing in T. bifasciatus 

 inclines to a pale olive -green colour. 



Teracolus Jachsoni, sp. n. 



Similar to T Thruppii, Butler, but larger, and having only 

 four long red spots on the fore wing. In T. Jachsoni the 

 black band which occupies the greater part of the inner 

 margin of the fore wing is connected with the black apical 

 markings. The black band on the hind wing is much 

 broader and continuous, and has not the white patch which 

 T. Thruppii shows on the inner portion of the posterior 

 margin. The shade of the under surface of the wing in 

 T. Thruppii is more of a yellowish white, while in T. Jachsoni 

 it is decidedly green. 



Pinacopteryx nigropunctata, sp. n. 



Similar to P. pigea, but with a black border along the 

 greater part of the costal margin, and having a very distinct 

 black edging round the apical portion of the fore wing ; the 

 hinder wing having a distinct black spot distributed along 

 the hinder margin at the end of each nervule. The under 

 surface is very different from that of P. pigea, being faintly 

 but distinctly spotted with black on the hinder wing, and 

 having two distinct black spots on the fore wing — one small 

 one at the apex of the discoidal cell, and another larger one 

 above the third median nervule in the centre of the fore 

 wine*.
