48 LLOYD'S NATURAL HISTORY. 



Ji^/;;w^/z^,whichmostentomologistshave,until lately, included 

 in the same genus ; but those of Diom have shorter fore-wings, 

 with the hind-margin more excavated, and sub-triangular hind- 

 wings. In Colanis the under surface generally resembles the 

 upper, but is paler; while in Dione the hind-wings beneath 

 and the apical half of the fore-wings are still more richly 

 spotted with bright silver than in our Queen of Spain 

 Fritillary. 



Respecting the habits of Colcenis and Dione^ Bates writes 

 that " they are seen only in open sunny places, such as waste 

 grounds, gardens, and the borders of woods, where flowering 

 bushes grow. They are never found in the great forest, but 

 seem to be attendants on man, making their appearance 

 wherever a clearing is commenced in the woods. They have 

 not a very rapid flight, nor much of the floating mode of pro- 

 gression when on the wing, but move about somewhat 

 irregularly, and settle frequently, their attraction being always 

 flowers, and never moisture, or filth on the ground, as is the 

 case with the more typical genera of Nymphalidce." He also 

 remarks on their close relationship with the HeliconiincR.

The genus Cethosia is characteristic of the Indo- and Austro- 

 Malayan Regions, to which it is exclusively confined, and where
