men olive-brown. Under surface pale olive-brown, darker towards 

 base and costa of primaries ; a central darker band on all the wings. 

 Femora of anterior legs chocolate. 



? . Paler, and the wings longer, giving the markings a more 

 elongate appearance. 



Expanse, S 47 millim., $ .51 millim. 



This species has a superficial resemblance to D. chaonia, but is 

 abundantly distinct from that insect. 



A fine series in Fryer's collection. 



Yokohama {Pryer). 



282. Drymonia delia, n. sp. (Plate XXXII. fig. 3.) 



cJ . Silvery grey, primaries with two pairs of parallel lines near 

 the base, the area enclosed being pale greyish brown in colour, 

 clouded along the costa from middle to near apex with brownish ; 

 submarginal line double, dark brown, much indented ; a small 

 brown discal dot followed by a reniform spot, outlined in black, and 

 filled in with reddish brown ; a series of black-marguied lunules. 

 Secondaries olive-brown. Head and thorax greyish brown. Abdo- 

 men olive-brown. Under surface pale brown, central area of 

 primaries darker. 



Expanse 44 millim. 



Also allied to B. chaonia.

284. Lophopteryx camelina, L. 

 Bombyx camelina, Linn. Syst. Nat. x. p. 507. 



I took two male specimens at Gensan in June 1889, and a female 

 at Hakodate in August of same year ; there were several specimens in 

 Pryer's collection, some of these are no. 231 and others no. 232 

 of his Catalogue. Of the last he observes very hke N. camelina. 

 Although there is some variation in size and colour, there is nothing 

 outside the usual range of aberration, and there is not a single speci- 

 men I cannot exactly match with an example of L. camelina from my 

 European series of the species.

285. Lophopteryx ladislai. 



Lophoiiteryx ladislai, Oberthiir, Diagn. Lep. Ask. p. 13; Etud. 

 d'Entom. V. p. 66, pi. ii. fig. 3. 



One male example in Pryer's coll. taken at Nikko. This species 

 appears to be very closely allied to L. cuculla, Esp.
