that I have folt obliged to give it a differ^'iit name, although its general appearance is such 

 tliat many entomologists would at once pronounce it ' a mere variety.' Male specimens were 

 only taken by myself at Malacca." 



Mr. Wallace appears to have been perfectly justified in this course. The amount of 

 differentiation is equivalent to what is considered as specific by entomologists, subject of course 

 to the final ruling of the breeder of this and the allied species.

 which are at present only known to 

 the writer by the original figure and 

 description, both of which are accord-

Male. — Wings above greyisli-wbite ; anterior wings with tbe neuration blackisb, the apical third 

 dusted with blackish, and witb a series of marginal black spots at tbe apices of tbe nervules ; ijosterior 

 wings with tbe apices of tbe nervules and tbe outer margin irregularly blackisb, tbe red submarginal spots 

 beneath giving a roseate tint above. Anterior wings beneath as above, but witb tbe apical blackish area 

 more broken, and containing a series of five greyisb-wbite spots. Posterior wings beneath greyish-white, 

 tbe neuration blackisb, tbe inner area bright ocbraeeous, and with a submarginal series of large red spots, 

 tbe largest towards anal angle, outwardly and somewhat broadly margined with black, and inwardly more 

 narrowly and obscurely with the same colour from apex to tbe lower median nervule. Body above and 

 beneath dark greyish ; legs dark greyish, more or less streaked with blackish. 



Female. Fonn (/.—Anterior wings above more or less suffused with blackisb, the cell and inner area 

 from lower median nervule to margin being palest ; five or six distinct, but obscm-e, greyish subapical
