Pieris gallengu. 



Male. — Upperside. Both wings pale orange-yellow; ante- 

 rior wings with the costa and apex narrowly pale brown. 



Underside. Anterior wings pale orange-yellow, with the 

 costa and apex orange-brown ; posterior wings orange- 

 brown. 



Near to P. Spilleri, but differs in colour, is smaller, and 

 the anterior wings are more rounded.

Acr(£a machequena. 



Male. — Upperside. Anterior wings transparent, clouded 

 with brown from the base to the end of the cell, and below it 

 to the inner angle ; posterior wings brown, a row of seven 

 lunular black spots on the margin ; beneath each lunule is 

 a small brown spot on tlie margin ; from the centre of the 

 costal margin to the centre of the hind margin is an irregular 

 row of eight distinct small black spots, within which is a 

 cluster of six spots near the base, also distinct. 



Underside. As above, but paler. 



Female closely resembles manandaza of Ward, while the 

 male is very close to ranavalona of Boisduval. The male 

 and female having been taken in copula, it would appear 

 clear that manandaza and ranavalona are also sexes of the 

 same species. Machequena differs from them in the colour 

 of the male and in size of the spots on the posterior wings, 

 which are smaller and distinct, not confluent as in rana- 

 valona, and the marginal row of spots is nearer the margin. 

 I am not aware that ranavalona or manandaza have been 

 taken on the mainland. 



Expanse 2 inches.

Acrcea salamho. 



Upperside. Semitransparent, greyish brown, the inner por- 

 tion in which the spots are placed much lighter and tinged
