" A distinct and well-marked species." (Mun-a)/, I. c.) 
I found this species fairly plentiful in July at Tsuruga, on the west coast 
of Japan. Fryer says it is common about Yokohama. My collectors obtained 
specimens in Central China at Chang-yang and Ichang, and at Moupin, 
Wa-ssu-kovv, and Pu-tsu-fong in Western China. I also received an example 
from Kiushiu, Southern Japan, where it was captured by a native collector.

Heteropierus, Dum. Zool. Anal. p. 271 (1806) ; Watson, Proc. Zool. Soc. Loncl. 1893, 
p. 89. Type, morpheus, Pall. 
" Antennae short, less than half the length of costa ; club moderate, straight, elongated, blunt. 
Palpi porrect, densely clothed with laxly set scales, almost concealing the third joint, which 
is short, slender, and bluntly conical. Pore wing : inner margin longer than outer margin ; 
cell less than two thirds the length of costa : vein 12 reaching costa before the end of cell ; 
upper discocellular short but distinct ; middle discocellular longer than lower ; vein 5 slightly 
nearer to 4 than to G ; vein 3 shortly before end of cell ; vein 2 more than twice as far from 
end of cell as from base of wing. Hind wing : outer margin even ; vein 7 well before end 
of cell ; discocellulars and vein 5 barely traceable ; vein 3 well before end of cell, more than 
twice as far from 2 as from 4 ; vein 2 nearer to base of wing than to end of cell. No 
epiphysis on fore tibiae. Hind tibice almost naked ; in morpheus with two pairs of spurs, in 
ornatus only with terminal pair. Abdomen reaching beyond the anal angle of hind wiugs."
