 Hubn. Bomb. pi. xliii. figs. 187, 188. 



Gastropacha quercifolia, Ochs. Schmett. Eur. iii. p. 247. 



Japanese specimens are rich in colour and most nearly approach 

 the form alnifolia, Ochs. Pryer says iu his Catalogue that larvae of 

 this species are abundant at Fujisan. 



A specimen which I bred from a larva found at Gensan is much 

 paler than either Japanese or European examples in my collection.

Bombyx populifolia, Esp. Schmett. iii. pi. 6. figs. 3, 4. 

 Gastropacha populifolia, Ochs. Schmett. Eur. iii. p. 45. 3.

237. NUMENES DISPARILIS. 



Numenes disparilis, Stand., Rom. Mem. sur Lep. iii. p. 200, 

 pi. xi. figs. 2a, 26. 



Two female specimens in Fryer's collection ; these are referable to 

 no. 136 of his Catalogue, and the locality there given is Asamayama ; 

 but whether this applies to both examples it is not possible to say, 

 as there are no locality tickets attached to the insects. They agree 

 exactly with specimens from Kiukiang. 



Asamayama {Fryer); Vladivostok, Askold. 



238. Lymantria albofascia, sp. n. (Plate XXXI. fig. 8.) 



cj . Brownish black ; primaries with an oblique broad white fascia 

 from costa towards apex to outer angle. Head, thorax, and legs 

 chestnut-brown. Abdomen yellowish brown beneath. Under surface 

 of primaries as above, but apical third yellowish white, with some 

 orange scales along costa and outer margin. 



Expanse 56 millim. 



One example of this remarkable species in Fryer's collection. 



Ohoyama {Fryer).

 p. 403 (1878); 111. Typ. Lep. Het. ii. p. 11, pL xxiv. fig. 5 (1878). 



Var. Fuse a. 



This species varies greatly in the matter of size. The male also 

 exhibits considerable differences in the depth of colour. The example 

 figured Plate XXXI. fig. 9 is one of four specimens of the darkest 

 form ; these were taken at Nagahama in July. I propose that 

 this form should be known as \AT.fasca.
