February. 



This is new to the Museum series. It differs a little from 

 the figure in that the border of the secondaries is regularly 

 dentate-sinuate internally, not enclosing spots of the ground- 

 colour ; this, however, is a likely variation to occur in a 

 species of Belenois, and may represent a seasonal phase.

 This is only the second example that I have seen.

How the describer of this species could possibly imagine it 

 a variety or aberration of P. pigea (which shows no orange at 

 the base of the primaries in the female) I cannot at all under- 

 stand ; its proper position is between P. astarte and P. orbona 

 (of which I hold P. larima, Boisd., to be the female *). The 

 male, of which we previously possessed a rubbed example 

 under my P. vidua, is of a similar character to P. astarte. 

 Herr Lanz describes females of the wet phase with well- 

 defined dark outer border to the primaries ; in all our speci- 

 mens this border is reduced on the outer margin to small spots 

 which terminate the veins (dry phase). 



♦ Prof. Auvivillius icUiUtifies Boisduval's iusect with " a very rubbed 

 example of thysa, Hoptfer " — a Belenois, I prefer an identification which 

 does not require abrasion to make it answer.
