Var. maculosa, Leech. (Plate XXVIII. fig. \,d ■) M"h. Differs from typical D. eugenes in its 
much larger size, the markings of primaries are all bright fulvous witli the exception of the 
apical spots, which are white. The markings of secondaries are also more conspicuous. The 
under surface is also much more brilliantly coloured, and tho majority of the markings are 
fulvous instead of white. Female. Similar to the male but the markings are paler and less 
interrupted. Expanse, d 3'J-40 millim., 5 42-52 millim. 
This form is cominouly distributed in ^^'estcl•u Cliiuu, and occurs at 
Chung-yaiig and Ichang in Central China, but the tyj)e docs not seem to 
be represented. 
In India I), eugencs occurs throughout the outer ranges of the Himalayas, 
and extends to Assam [dc Niceville). Mr. Elwes (Trans. Ent. Soc. Lond. 
1888, p. 370) states that it is found in Sikkim from 6000 to 10,000 feet. 
Genus POLYCiENA. 
Pohjcana, Staudinger, Stett. eut. Zeit. xlvii. p. 227 (1886). 
" Differs from A>)»eo6i((« in its more delicate structure: in the longer and somewhat differently 
shaped wings, and in having spots rather than bands on the upper surface. Primaries are 
convex on the outer margin, and the apex is obtuse. Secondaries are rounded on the outer 
margin with an obtuse angle about the middle in the male, and the anal angle is not acute as 
it is in Nemeohiu.i. Precostal vein leaves the costal nervure at almost a right angle. Antennae 
long and slender. Head, palpi, and thorax are clothed with longer hairs than in Xemeohius."

Une ligne jaune orange submarginale, n'atteignant pas le bord costal des superieures et 
reproduisant les taches fauve rougeatre du dessus, separe les deux dcmiers rangs de ces 
taches noires. Le rang le plus voisiu de la base y est relio par des traits epais suivant lo sen.^ 
des nervures. Le dessous de I'abdomen est blanchatre.
