Ogove River antl at Efulen, Cameroon, the females of which are unmis- 

 takeably referable to obscura Butler. The males do not agree with 

 Drury's figure of the insect he named A. epimethea in that they lack the 

 dark costal area on the upper side of the secondaries, well shown in 

 Drury's figure. We have, however, a number of males, not bred from 

 larvae but captured at various localities, which agree absolutely with 

 Drury's figure of epimethea and which have a different facies from the 

 males which by the test of breeding are known to be that sex of obscura 

 Butler. The two forms seem to me to be at least varietallj' distinct, 

 though very closely allied to each other.

Plate XIV, Figure 8, 9 

 9 . Eyes black, frons pale orange with a black spot in the center; tegula? orange, 

 with a black spot at the insertion and on the posterior margin; patagia orange with 

 two blue-black suboval spots succeeding each other in the middle; a blue-black 

 median dorsal line, which runs from the posterior margin of the tegulse to the meta- 

 thorax, but does not appear to be continued upon the dorsum of the abdomen; at 

 the point of union of the thorax and abdomen on either side three orange-yellow spots, 

 bordered with blue-black ; dorsal and lateral surfaces of abdomen solidly bluish black 

 until near the end, where there are two orange-yellow streaks on either side; oviposi- 

 tor yellow at extremity; the legs blackish, as is also the under side of the thorax, 

 except for the presence of some tufts of yellow hairs at the insertion of the legs; 

 anterior segments of the abdomen on the under side dark like the upper side, the 

 posterior segments orange-yellow on the lower side. Both wings on the upper side are 

 pale bluish, densely spotted all over their surface, including the anterior margin of 

 the hind wings, with small pale orange-yellow maculations, those at the end of the cell
