Papllio Blrcliallii. 



Alls nigris, serie submarginali macnlarurn ochracearum ; anticis 

 maculis quatuor analibiis ; posticis fascia transversa viridi- 

 ochracea, posticis subtus macula costali maculaque anali flavis, 

 maculis quatuor intermediis minutis lunulisque submargina- 

 libus sanguineis. 



Upperside dark brown. Anterior wing with a bifid spot at the 

 middle of the costal margin, a submarginal band of conical spots, 

 and above them, near the anal angle, four ill-defined spots, all 

 ochre-vellow. Posterior wing dentated, with a central, irregular, 

 deeply-sinuated, transverse band of grey-green, divided into eight 

 by the nervures (one part within the cell), and a submarginal band 

 of spots of the same colour. 



Underside rufous-brown. Anterior wing with a twice curved 

 macular band of seven greenish-yellow spots, commencing at the 

 middle of the costal margin by the small spot described above, 

 and ending on the inner margin near the anal angle ; the second 

 spot (within the cell) lunular; the third small, triangular; the 

 fourth hastate ; the fifth and sixth conical ; the seventh small ; a 

 submarginal band of five pale yellow spots between the anal 

 angle and the middle of the wing. Posterior wing with a round 

 bifid spot at the middle of the costal margin, two lunular spots 

 (one small) at the anal angle, and between them, in a direct line, 

 four minute scarlet spots; also a submarginal band of seven 

 spots of the same colour. 



Exp. 4j'^Q inch. Hab. New Granada.

 him with a large collection of beautiful species (many of them 

 new) from Bogota by a brother, to whom, for his zeal in the 

 pursuit we have so much at heart, I have dedicated this species. 



From Mr. Edwin Birchall 1 have received, though a stranger 

 to him, the same generous kindness which is characteristic of all 

 the Lepidopterists with whom it has been my lot to associate. 



This species has a double aspect ; it seems to connect the two
