Felder,* that it has always been considered to be the female of a closely- 

 allied species. Owing to its having very small and smooth anal valves 

 I had always considered it to be of that sex ; bnt having heard that 

 Mr. Watson has found plumules [androconia] on the wing, and therefore 

 pronounced it to be a male, I relaxed my specimens, and by opening the 

 valves found that he was right, and that all the specimens in my own 

 and other collections are males. This being the case, it is evident that 

 it has no close ajjindf/ whatever with P. ithome, or with any other known 

 butterfly, so that its name will be a good example of ' lucus a non 

 lucendoy and will serve to recall the error to which its analogical 

 resemblance to the female of P. hliome gave rise. It must now come in 

 the group of true Pieris, and is nearest to P. rachel, Boisduval, though 

 forming a distinct subsection." From the synonomy above it will be 

 seen that the iy]}Q species has been placed in three genera. Wallace 

 correctly located it in Pieris group h, which equals Huphina of Moore, 

 the latter was differentiated many years after Wallace Avrote. Roths- 

 child's location is very nearly correct^ the present genus being very 

 near to Huphina. 1 have only seen males of this species.

Habitat ; New Guinea. 



Messrs. Grose Smith and Kirby in redescribing and figuring this 

 species say that the specimen figured is a male ; but the figure and de- 

 scription do not agree with a male in my collection from Humboldt 

 Bay, North- West New Guinea, which differs in having the black borders 

 to both wings on the upperside very much narrower, in the forewing 

 fining away to nothing before reaching the anal angle, and in the hind- 

 wing being almost reduced to spots between the veins. In their figure 

 also they show and describe two red spots on the luiderside of the hind- 

 wing, which are absent in my specimen. Under Tachyris enri/.nudha,
