[Dr. Packard, without comment, has copied Rothschild's remark (Nov. Zool., 11 (1895), 

 p. 47): "I can find no character to separate Tropaea from Actias." He has also copied Roths- 

 child's list of the species, as follows (I add a subspecies more recently described)]: 



1. A. isabellse, (Graells). 1 [Spain.] 



2. A. sinensis (Walker). [China.] 



3. A. luna (L.). [Genus Tropaea. American.] 



ab. azteca (Pack.), 

 ab. rossi (Ross). 

 ■ subsp. dictynna (Walker). 



4. A. selene (Hubner). 



subsp. ningpoana (Felder). [China.] 



ab. maasseni (Kirby). 

 subsp. artemis (Brem.). [Amur.] 

 ab. gnoma (Butler). [Japan.] 

 ab. dulcinea (Butler). [Japan.] 

 ab. aliena (Butler), 

 [subsp. caUandra Jordan 1911. Andamans.] 

 [Dr. Packard examined Maassen and Weymer's account of Kirby's maasseni from China 

 (a 9 ), and reached the conclusion that it was a true Tropaea, with venation as in luna, differing 

 from luna in markings and shorter tails only. "A brown band connects ocellus with brown-red 

 costa as in luna, but there is a distinct straight extradiscal brown band," and tails are only 

 about half as long.]

Imago. — Three o* , three 9 . Head wbite, thorax and abdomen wliite, a transverse pro- 

 thoracic pink madder-red band connecting the costal edges of the fore wings; sides of the front 

 of the head narrowly edged with pink-red. Palpi rather slender, reaching nearly to the front, 

 red. 



Fore wings acute, decidedly falcate, the costa much curved toward the apex; the outer 

 edge distinctly incurved. Body and wings pale soft pea-green, tinged with yellow; fringe 

 yellow and ends of the tails yellow. A faint greenish brown basal fine which is not visible 

 beneath; it is straight in its course and is rather far from the insertion of the wing. Two sub- 

 marginal fines, the inner (extradiscal) being broader and more distinct than the outer. The 

 extradiscal is present on the hind wing, but is bent at right angles at base of the tail. 



1 [This is now generally known as Oraellsia isabellse, and is so described above. \
