Hemaris mandarina, Butl., Proc. Zool. Soc. Lond., 1875, 
p. 239, pl. xxxv. fig 2. 
There were specimens from Oiwake and Yokohama in 
Pryer’s collection. I took the species at Gensan, Fushiki 
and Hakodate, and have received examples from 
Kiukiang. 
The rays from the outer marginal border, which are 
conspicuous in the type form, are altogether absent in 
mandarina, and all gradations between these extremes 
are exhibited. 
Distribution. JAPAN; YESSO; COREA; EASTERN, 
CENTRAL, and NORTHERN CHINA.

Sesia alternata, Butl., Ann. and Mag. Nat. Hist., (4) xiv,

Hemaris alternata, Butl., Il. Typ. Lep. Het., 11. p. i, 
pl. xxi, fig. 3 (1878). 
According to Pryer, this species would seem to be 
common about Yokohama; it is recorded from Oiwake 
and Hakodate, and I obtained specimens at Gensan 
in July. My native collectors captured four examples 
at Chang-yang. 
Fixsen (Rom. sur Lép., ili, p. 323) suggests that 7. 
alternata may be referable to H. affinis, but the former is 
easily separable from the latter.
