ACROPllTHALMIA.— C(ENONYMPHA. 93 
Acrophthalmia thalia. (Plate x. fig. l, 6 .) 
Acroj)htltahnia thalia, Leech, Entomologist, xxiv., Suppl. p. 25 (1891). 
Male. Allied to AcrojiJithalmia chione, Fcld.*, but the white central band is narrower, extending 
from costa to inner margin on the secondaries, and from inner margin almost to costa on the 
primaries ; the ocellus on the upper surface of primaries is placed almost exactly as in 
A. chione, but, although smaller, is more distinct, and has a minute white pupil; the second- 
aries also have a distinct ocellus towards anal angle; there are two pale lines parallel with 
outer margin on all the wings, but these are most clearly defined on the secondaries. On the 
under surface the ocelli are as above, but ringed with fulvous, and there are, in addition, one 
ocellus at outer angle of secondaries and two smaller ones between it and that at anal angle ; 
the white central band and double marginal line on all the wings exactly as above, but there 
is also a narrow leaden-grey submarginal band on each wing ; that on the primaries starts 
from the costa before the apical ocellus, around which it curves, and then continues a slightly 
sinuous course to the inner margin; on the secondaries the band is deeply indented between 
the two larger ocelli. Fringes white. 
Female. Similar to the male, but the central white band is rather broader and the external margins 
of the wings are rounder. 
Expanse 50 millim. 
Occui's at Pu-tsu-fong and Omei-shan, in July. 
Genus CCENONYMPHA. 
Ccenonympha, Hiibner, Verz. bek. Schmett. p. 65 (1816) ; Westw. Gen. Diurn. Lep. 
p. 396 (1851). 
" Body small, very hairy ; wings entire, rounded ; fore ones with the three principal veins swollen 
at the base. 
" Head rather small, clothed, especially in front, with long hairs, not forming a conical tuft. 
" Eyes prominent, naked. 
" Antennce short, scarcely half the length of the fore wings, slender, anuulated with white, 
terminated by an elongate ovate club, which is channelled beneath. 
" Labial 2^alpi '^ery compressed, porreoted obliquely, quite straight, and elevated to about the 
level of the top of the eyes, and advanced further in frout than the length of the head, 
thickly clothed beneath with long bristly hairs set on at right angles ; the terminal joint 
rather long, slender, acute, and much less slightly clothed with hairs. 
" TnoEAX small, very thickly hairy. 
" Fure tvinr/s rather large, entire, hairy, and with long fringe. Costal margin moderately arched ; 
apex rounded. Apical margin convex, nearly three fourths of the length of the costal. 
Inner margin nearly straight, about equal in length to the apical margin. Costal, median, 
and submedian veins equally swollen at the base. Postcostal vein with its branches free ; 
the second arising just beyond the extremity of the discoidal cell, and the third and fourth
