" This species seems to have been confounded hitherto with D. efjcon ; l)ut tlic very different colour 
and small dimensions of the stripes and spots of the uppcrsido well distinguish it." (Bates, 
I. c.) 
Var, maculosa, Leech, (riate XXVIII. fig. l,c? .) Mcde. Differs fr om typical I), eur/enes in its 
much larger size, the markings of primaries are all bright fulvous with tlie exception of the 
apical spots, which arc white. The markings of secondaries are also more conspicuous. The 
under surface is also much more brilliantly coloured, and the majority of the markings arc 
fulvous instead of white. Female. Similar to the male but the markings arc paler and less 
interrupted. Expanse, (S 39-40 millim., 5 42-52 miUim. 
This form is commonly distributed in Western China, and occurs at 
Chang-yang- and Ichaug in Central China, but the type does not seem to 
be represented. 
In India D. eiigenes occurs throughout the outer ranges of the Himalayas, 
and extends to Assam [de 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. 
Polycana, Staudinger, Stett. ent. Zeit. xlvii. p. 227 (1886). 
" Differs from Nemeohius 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 Nemeohius. Precostal vein leaves the costal ncrvure at almost a right angle. Antennae 
long and slender. Head, palpi, and thorax are clothed with longer hairs than in Nemeohius."

Emesis princeps, Oberthiir, Etud. d'A^'atom. xi. p. 22, pi. vii. fig. 57 (1886). 
" Le dessus est brun uoir, avec une ligne margiuale de taches intrancrvuralcs fauve rougeatre, sauf 
les trois, vers lo bord costal, qui sont chamois pale et un second rang extracellulaire de 
taches egalement chamois pale qui font toutes ressortis une ombre interieure figurant un 
point tres noir asscz gros. La cellule est marquee d'un point noir iutcrieurement eclaire d'une 
tachc chamois. 
"Le dessous est jaunc paille, un peu plus l)lanchatre aux inferioures, avec des dessins et taches 
noires formant trois series principales de lignes a peu pres paralleles au bord exterieur. 
Une ligne jaune orange submarginale, n'atteignant pas le bord .costal des superieures et 
reproduisant les taches fauve rougeatre du dessus, separe les deux derniers rangs de ces 
taches noires. Le rang le plus voisin de la base y est relie par des traits cpais suivant le sens 
des uervures. Le dessous do Tabdomen est blanchatre.
