discoidal cell; another (longitudinally) close to costa, 

 immediately before sub-apical bar ; 2 small rounded spots 

 close to apex ; a sub-marginal row of 3 — 4 small spots 

 just below sub-apical bar, succeeded by a hind-marginal 

 row of smaller spots. Hindwing : one large white patch 

 occupies the greater part of the area, leaving only a 

 narrow basal, a linear costal, and a broad hind-marginal 

 (much widened at anal angle) border, diminishing gradu- 

 ally along inner-margin to base. Underside. — Similar, 

 but the white markings all larger and Avith suffused edges 

 — notably the hindwing patch, which covers the whole 

 inner-marginal and anal-angular region, and leaves only a 

 rather narrow brown border at apex and along upper part 

 of hind-margin. Foreiving : apical region beyond bar 

 brown. Hindwing : two small white spots at base. 



In the S the nervures are strongly clouded with black, 

 as well as the inter-nervular rays, in the large white patch 

 of both wings; in the 2 this character is either wholly 

 wanting or very faintly indicated. 



Closely allied to A. Niavius, Linn., but seems con- 

 stantly to differ as follows, viz. : (1) its size is consider- 

 ably larger^ the West African form expanding only 3^ to 

 3| inches; (2) the great extent of the lohite patches 

 (especially that of the hindwings, which in Niavius does 

 not extend beyond the extremity of the discoidal cell) 

 readily distinguishes it. In the clouding of the nervures 

 and inter-nervular rays the $ Dominicanus exceeds the 

 $ Niavius, but the reverse appears to be the case with 

 the $s.
