 Ceylon. In Coll. B. M. 



1 belieye that A. reversa, Walk. (Lep. Het. xiv. p. 1399, n. 18), 

 is nothing more than a variety of this species. The extreme 

 variability of the species of Aclicea is well known ; and, therefore, 

 the mere obliteration of the pale markings on the primaries is 

 not likely to be of specific value. 



Ophisma ezea.

? Ophisma dejeanii, " Boisduval, Faune Ent. de Madag. 

 p. 102, n. 3, pi. 15, fig. 4" (1833) ; see Walker, Lep. Het. 

 xiv. p. 1395, n. 9 (1857). 



West Africa. In Coll. B. M. 



In spite of the similarity of the West African specimens to 

 Boisduval's figure, I believe that Walker is wrong in his identifi- 

 cation, and that the true " O. dejeanii" of Boisduval is a dull 

 form of the species subsequently described and figured by Guenee 

 as Ophisma prcestans ; the broad apical ochreous patch of the 

 secondaries favours this view. It is significant, as evidencing 

 the value of the generic characters by which M. Guenee declines 

 to distinguish the genera Ophisma and Achcea, that, whilst he 

 calls his own species an Ophisma, he places Boisduval's in Achcea.
