restricted to the mountains of Nepal, Silhet, the Himalayas, at elevations of about 5,000 feet and 

 upward. Hutton state that "This species, I believe, is confined to the hills from 5,000 feet 

 upward to 7,000 feet, and perhaps higher; it also occurs in Silhet." (Horsfield and Moore's Cat. 

 Lep. Insects of Museum East India House, 11, p. 404.) In the Paris Museum are examples 

 of A. selene from India, Java (one very large), Silhet, Macao, and northern China. In China it 

 ranges from the tropical coast to Shanghai and westward to the interior, and also in Yunnan. 



Climatic races. — My notes made while examining the specimens in the British Museum are 

 as follows : 



The males from Ceylon, India, and Thibet appear to have more pointed fore Avings than 

 those from China. 



Three small males from Thibet are smaller and have more acute fore wings than three males 

 from China (Kwei-chow or Kui-cb.au, on the Yang-tze-Kiang River, about 800 miles west of 

 Shanghai. In one of the males the hind wings are more pointed at the apex than the two others ; 

 they have the basal line. The ocelli are a little smaller. In these examples from Thibet and 

 in a pair ( c? and 9 ) from Omei-Shan, elevation of 3,500 feet, 1 the ocelli are smaller and less 

 black on the inner edge than in those from Ceylon. Also three males from Kanagra, Thibet, 

 have sharp apices of the fore wings. In one S from Kanagra the ocelli of the hind wings show 

 some aberration, being excavated on the outer edge; the same variation was noticed in a pair 

 ( c? and 9 ) from Mussooree, Himalaya Mountains. 



It would appear from these facts that the Chinese form, ningpoana (Felder), is probably a 

 climatic race, with slight though constant differences from the Indian and Tibetan form selene 

 given by Cramer in 1775, who states that his examples came from the coast of Coromandel 

 and also from Ceylon. The name selene was Hiibner's. Hiibner gives no locality, while the 

 plate has no number and no text. 



[A later penciled note gives the result of examination of ningpoana at the Paris Museum, 

 as follows:] 



Fore wings with two parallel faint slightly wavy dark lines, and one on hind wings; ocellus 

 disconnected from costa; male fore wings pointed, female much less so. 



Larva of A. selene. — From a blown specimen in British Museum. [Length about 78 mm.] 

 Shape as in Moore and Horsfield's figure; head rounded, chestnut brown with a few long hairs 

 in front; body cylindrical, segments as in T. luna, deeply incised, angular; prothoracic segment 

 small, narrow, no tubercles, but in place of each of two dorsal ones are four slender spines, dark, 

 arising from green conical bases, and a pink spine on each side low down, giving rise to two hairs. 

 A pair of large dorsal tubercles on second and third thoracic segments, of the same size, green 

 at base, then a black ring (red in Moore's drawing) and end orange-yellow, giving rise to five 

 or six sharp slender spines, and two to three hairs, and a third or fourth very long hair, about 

 three times as long as the tubercles. Two rows of lateral orange-red small rounded tubercles, 

 one above and one below spiracular line on third thoracic segment. Abdominal segments 1 to 7 

 with a pair of orange-red similar tubercles, those of the lateral rows much smaller, those of the 

 supraspiracular row about half as large as those of infraspiracular row. The single dorsal 

 [tubercle] on eighth abdominal segment large, high, all green, and bearing four to five sharp 

 small spines like those on thoracic segments and also giving rise to five long unequal hairs. 

 Spiracles orange-red, with whitish lips. Lateral line orange-red above and yellow beneath. 

 Anal legs brown along end or plantula (whitish edge of brown portion seen in Moore's figure, 

 not seen in blown specimen); long black hairs arise from all and body has scattered shorter 

 hairs. 



Cocoon. — Oval, alike at each end, 1 J inches long and f inch thick; no stalk. [The cocoon of 

 A. selene is reddish, but A. callandra (A. selene caUandra Jordan) has the silk pure white; both 

 have been figured by Watson, Wild Silk Moths of the World.] 



1 As we understand it, Omei-Shan is a mountain 11,100 feet high, situated east of Thibet in China, north ot Yunnan, in lat. 29" and long. 102J°, 

 near Kia-ting, and on the head waters of the Yang-tze-Kiang River. [Watson has described a subspecies omcishaTia.]
