xiii, D. 4 Wileman: Japanese Lepidoptera 159 



I have taken this species, some specimens of which are ap- 

 parently referable to mathura and others to form aurora, in 

 the above-named localities. I also captured many specimens of 

 form aurora, female, on the trunks of oak trees in the forests at 

 Jozankei, near Sapporo, Hokkaido (Yezo), in August, 1896. The 

 females were engaged in depositing their ova in the crevices of the 

 bark with their long ovipositors. I also took male aurora in 

 abundance at light in the same locality, also var. fusca Leech. 

 The species occurs in Hokkaido (Yezo), Honshu, Shikoku, and 

 Kyushu. Matsumura records the species from the same islands 

 under mathura. 



Leech also gives Loochoo Islands (Ryukyu) and Kurile Islands 

 (Chishima-to) as localities for mathura and aurora. Swinhoe 

 separates mathura and aurora and says of Lymantria aurora 

 Butler : 



In B. M. collection. 1 J', 1 ?, Japan (types). 1 c?, 1 ?, Yesso (=Hokkaido). 

 4 c?, Nagahama, (province Omi.), including type fusca. Sunk to mathura 

 in the B. M. collection, but it is a distinct form, the male being uniformly 

 blackish-brown. Butler's type example is an old, worn and faded specimen; 

 whether his female type is really the female of this form is I think very 

 doubtful. 



Swinhoe says of Lymantria mathura Moore : 



In B. M. collection. 1 c? N. India (type). 1 c^, 1 $ Kangra. 1 ? Dehra 

 Doon. 2 c?, 1 ?, Sikhim. 1 $, N. E. Himalayas. 3 c^, 1 ?, Loochoo Islands 

 (Ryukyu). 1 ? Chefoo, East China. 2 ? Omeishan, West China. 2 c?, 3 ? 

 Japan. 



Time of appearance. — Larva, May to July; imago, June to 

 August. 



General distribution. — Lymantria mathura: Kashmir, Japan, 

 and widely distributed in India {Stra7id) ; Manchuria (Mat- 

 sumura) . Lymantria aurora: Eastern Siberia (Amurland), 

 China, Korea, and Japan (Strand).
