1. Genus: Actias Leach. 
A. heterogyna Mell (Vol. 10, pi. 55 B a) is very local in its occurrence. Like the related A. duber- 
nardi Oberth. (Vol. 2, p. 211), it occurs in mountainous territory. Its wing expanse is 114—124 mm in A 
and 135 mm in V- The A is of yellow colouration, the ^ pale green. Both have a distinct undulate grey post- 
median band on both wings, which is indented on the veins. There is a less distinct submedian line. The 
discocellular spot resembles the ground colouration and is intersected longitudinally by a red streak. This is 
occasionally only narrow, but can expand embracing the entire outer half. The anterior half of fore wings 
and the upper part of hindwings bear a narrow blue arched streak near the margin. This is edged with black, 
more heavily outwardly, less so inwardly. Between this streak and the red middle streak there is a narrow 
ochreous longitudinal mark. I he tail of hindwings is about 2 / 5 ths of the length of same. In the $ it curves 
outwards, in the 9 it is more twisted. In the A forewing is yellow, base being greenish yellow and hindwings 
lemon yellow. Costal margin widely red-brown to beyond the middle of wing. S. China, presumably crossing 
here into palaearctic territory. 
A. apollo Rob. (14 a) described from a from Hiogo in central Japan. Its wing expanse is 88 mm 
and it differs from A. selene-^ (Vol. 2, p. 211 and Vol. 10, pi. 55 C b) by the shape of the forewings. The 
apex is not elongated as in the latter but almost rectangular. The outer margin of forewings in general forms 
a straight line, but same is, like the outer margin of hindwings faintly but regularly undulate. Hindwings 
are shorter than in selene-^, but longer than in the larger artemis Brem. (Vol. 2, p. 211, pi. 33 b). In the basal 
area hindwings are wider than in selene. Upperside is monotonous pale gree-n, rather greener than artemis. 
The veins seem to be more boldly marked being of pale brownish colouration. The ocelli are approximately 
similar to those of artemis, but they are more pronounced and the yellow areola to ocellus of hindwing is 
wider. Fringes yellowish. Forewings have a shadowy blackish stripe in the middle between the outer marg¬ 
in and the discal spot which extends from costa to the middle of the cell between the submedian and the 
1st median nervure. In front of same and not precisely in the middle between this stripe and outer margin, 
there is a shorter and very indistinct blackish stripe. The subbasal transverse stripes, which are very dist¬ 
inct in selene, are missing in apollo. On hindwings there is a rather indistinct blackish submarginal extend¬ 
ing from the anterior radialis to base of tail. The red costal streak on forewings is paler than in selene, but 
darker than in artemis. Frons is darker yellowish than in selene. Underside is somewhat duller than upper- 
side. The antennae are darker than in the two related species, the single pectinations are slightlv longer 
than in selene and the shaft of the antennae is strikingly darker. 
2. Genus: Graellsia Grt. 
G. isabellae Graells (Vol. 2, p. 212, pi. 33 c). The race established by Oberthur with a flourish of 
importance and denominated by the fine name of galliaeglotia as representing the isabellae captured at 
L’Argentiere-la-Bessee in the french High Alps, has proved to be descended from Spanish parents of isabellae 
that were let loose there and therefore galliaegloria must be withdrawn. 
3. Genus: Samia Jftm. 
S. cynthia Drury (Vol. 2, p. 212). ab. viridis Mezg. ground colour of wings green or very slightly 
brownish green. ab. bicolorata Mezg. has wings marked with yellow and green, ab. punctata Mezg. has
