194 Mr. J. H. Leech on Lepidoptera Heterocera 



I obtained this species at Nagasaki and in Satsuma in May, 

 at Gensan in July, and I have received specimens from 

 various localities in Central and Western China. There 

 were some examples from Kintokisan and Nikko in Fryer's 

 collection. 



It is very variable, and I have intergrades between the 

 typical form and striolata, Butl. One specimen has three 

 purple-brown spots on primaries, and a patch of the same 

 colour on secondaries ; there is a similar specimen in the 

 series of T. crocoptera from Dharrnsala in the National Col- 

 lection at South Kensington. 



Distribution. Japan ; Corea ; North, Central, and Western 

 China ; North India. 



Thinopteryx pr^cetoraria. 



Urapteryx preetoraria, Feld. Reise Nov., Lep. v. pi. cxxii. fig. 13 

 (1875). 



One female example taken at Omei-shan, Western China, 

 in July. 



This specimen seems very distinct from T. crocoptera) Koll. 

 Distribution. Sylhet, Western China. 



Thinopteryx delectans. 



Urapteryx delectans, Butl. 111. Typ. Lep. Het. ii. p. 45, pi. xxxv. fig. 2 

 (1878). 



Several specimens from Fujisan, Ohoyama, and Nikko in 

 Pryer's collection. I have examples from Ichang, Chang- 

 yang, Wa-shan, Omei-shan, and the Provinces of Kwei-chow, 

 taken in June and July. 



The yellow marking in this species is subject to variation ; 

 in typical specimens the wings are thickly sprinkled with 

 yellow, whilst in other examples the yellow is confined to 

 the median area and outer margin. 



Distribution. Japan ; North, Central, and Western China.
