Butterflies from Madagascar. 123 



marginal row of spots confluent with the marginal row, the 

 others nearly confluent. Posterior wings with the apices of 

 the submarginal lunules much elongated, almost extending 

 to the marginal row, which are fully developed, the marginal 

 lunules on each side of the tails extend down them almost to 

 the end ; across the disk the outer row of sinuate black lines 

 is crowned with silvery blue in the middle row, the irregular 

 black spots extend inwardly in a conical shape, atid are 

 margined outwardly with another row of bright blue lines ; 

 inside the cell at its end is a broad curved black spot centred 

 with blue ; the veins are black, broadly black on the mar- 

 gins. Both wings between the spots and at the base irrorated 

 with stramineous scales. Antennas rufous. 



Expanse of wings, $ 3f , ? 4f inches. 



This species connects erithonius, which is an Asiatic, with 

 demoleuSj which is an African species. I have many speci- 

 mens of demoleus from Madagascar, and was at first disposed 

 to consider erithonioides a variety. The development of the 

 tails in the female is very remarkable. This species is much 

 larger than erithonius , and I have specimens of the female 

 nearly 5 inches across the wings. A considerable series was 

 sent. 



Pieris ramona. 



Male — Upperside. Bath wings white. Anterior wings and 

 inner three fourths of costal margin narrowly, thence to the 

 apex broadly black, the black gradually narrowing along the 

 outer margin to a little beyond the middle median nervule, 

 where it ceases ; a small black spot at the end of the cell, 

 a cluster of black scales forming an indistinct submarginal 

 spot between the upper and middle median nervules, the 

 space from the outer third of the cell, and thence over the 

 disk to the black apical band and nearly as far as the pos- 

 terior angle, bright orange. 



Underside. Anterior wings very pale orange stramineous, 

 brighter towards the base, inner margin nearly white; the 

 spots as on the upperside, but larger and very black. Pos- 

 terior wings, inner half of costal margin bright orange, the 

 rest of the wings stramineous. 



Female. — Upperside. Anterior wings pale orange, costal 

 and outer margins narrowly black, a black spot at the end of 

 the cell ; four submarginal black spots — the first below the 

 third subcostal nervule minute, the second larger, below the 

 first discoidal nervule, the third the largest, below the upper 

 median nervule, the fourth below the lowest median nervule, 

 about the same size as the third spot but less defined ; a few
