dimorphism or variation. Of course we await the recital of the experiments which will 

 demonstrate this conclusion, and doubtless this will soon be afforded, for Mr. de Niceville is a 

 most careful lepidopterist. Meanwhile this proposed seasonal identity of the two forms is 

 eminentl)' reasonable and probable. It is therefore to be regretted that, awaiting these fuller 

 particulars, Mr. de Niceville's interesting and valuable theory should have been subjected by 

 another writer to some jocose criticism,* and the fact of the two forms having been found flying 

 together does not prove that they entered the imago condition at the same time. Should this 

 theory prove to be correct — and I certainly incline to the opinion that it will — a necessary 

 qualification will be given to many of our specific views, and more benefit will be afforded to 

 the study of Lepidoptera than by an annual contribution of the descriptions of three or four 

 hundred so-called new species.

Male. Wings above fuliginous-browu ; anterior wings with a fuscous oblique patch at end of cell, 

 followed by a subapical ochraceous subquadrate spot, beneath which is a very small spot of the same colour ; 

 posterior wings with two small whitish submarginal spots separated by the second median nervule. W^ings 

 beneath brownish-ochraceous, much mottled with small darker strigffi ; anterior wings with a dark oblique 

 fascia almost crossing wing beyond end of cell, two small subapical greyish-white spots, and some similar and 

 very indistinct spots placed between the nervules near outer margin ; posterior wings with a discal curved 

 dark fascia crossing wing beyond end of cell, and some submarginal small and obscure greyish spots as on 

 anterior wings ; outer margins of both wings warmer ochraceous. Body and legs more or less concolorous 

 with wings. 



Exp. wings, 73 to 7B milim.

A male specimen captured in Perak, and now contained in the Calcutta Museum, is here 

 figured. The female is larger and paler in hue than the male, and the under surface of the 

 wings is more ochraceous and less prominently mottled with the dark strigfe.
