614 MR. A. G. BUTLER ON THE GENUS ADOLIAB. [NoV. 26, 



Described originally as a species of Lexias, Boisd. Gen. ( = Sym- 

 phcedra). The structural characters which separate SymphcBdra 

 from Adolias are not verj' considerable, and from their uncertainty 

 seem almost to indicate a state of transition ; the style of coloration, 

 however, is quite distinct. 



DiCHORRAGIA, g. n. 



Typical species Bichorragia nesimachus. 



Most nearly allied to Apatura {A. erminia), but differing slightly 

 in the neuration, the hind-wing cell being partially closed by an in- 

 terrupted and rather delicate lower discocellular nervule. In colour- 

 ing the type more nearly resembles SymphcBdra cyanipardus $ 

 than anything else, which probably accounts for its retention in 

 Adolias.

Stibochiona, g. n. 



Typical species Stibochiona coresia, Hiibner. 



Allied to Diadema (D. alimena), hut differing from it, from Apa- 

 tura, and from Adolias in liaA'ing the discoidal cells of both wings 

 distinctly closed, the middle and lower discocellulars of front wing 

 forming a continuous arch, the upper discocellular of hind wing 

 obliquely arched, the lower a little longer than the upper, slightly 

 arched, and meeting the median nervure somewhat obliquely at the 

 origin of the second and third branches. Colours intermediate be- 

 tween Adolias cocytus and Diadema alimena,

The type of the genus Hypolimnas is a Diadema, so that that 

 term cannot be adopted.
