a perfect annulus ; the fourth is almost the same, 

 only that it is a little open towards the edge. In 

 the three other divisions there is always a crescent 

 at the edge and another towards the middle, with 

 the points turned towards the margin. The in- 

 ternal half-circle shows some sky-blue scales. The 

 body, feelers, and legs are black ; some points in 

 the neck, three transverse rows of points on the 

 breast, on each side, as well as streaks on the 

 thighs and legs, are white. These white spots on 

 the thorax, as well as the same colour of the 

 lower wings, at the root, in the preceding butterfly, 

 make me suppose that both may be of one kind. 

 My specimen is a male. 



VI. PAPILIO ASTENOUS, F. 



From Manilla. — Of this beautiful large butter- 

 fly only the female had hitherto been known ; 

 the male, which is much smaller, is however 

 greatly distinguished by the marking of the lower 

 wings, which are likew^ise fulvous ; but the exterior 

 border has only narrow black scallops. Near the 

 scallops there are a number of black scales on a 

 yellow ground, and which form another row of scal- 

 lops, which gives this part the appearance of being 

 covered with black gauze. The radii on the upper 

 wings of the male are whitish, though they are 

 yellowish in the female. The narrow strong- 

 nerved wings of the male are remarkable, ofwJiich 

 the • upper wings are mostly found half scaled.
