DESCRIPTION OF A NEW LUEHDORFIA FKOM JAPAN. 



By J. H. Leech, B.A., F.L.S., &c. 



(Plate I., Fig. 1.) 



LuEHDORFIA JAPONICA, llOV. Sp. 



Expanse, 70 mm. Primaries pale yellow, black at base and externa 

 margin, with three transverse oblique black bands on the disc, and one 

 parallel with outer margin, with which the third oblique band is united 

 below the middle ; a black dash from the costa between first and second and 

 second and third oblique bands. Secondaries pale yellow, with a broad black 

 band along the inner margin, and another, oblique and interrupted, on the 

 disc beyond which is a black costal dash : the outer third black, enclosing 

 five blue spots, and edged externally with some orange patches; a 

 conspicuous crimson blotch above anal angle. Fringes chequered black and 

 white. Under surface as above, but the crimson colour assumes a band-like 

 form, traversing the wing parallel with outer margin from anal angle to 

 second subcostal nervule ; the orange on outer margin also forms a 

 complete band. 



This species was erroneously referred to as L. lyuziloi by 

 Mr. Pryer in his catalogue of * Lepidoptera of Japan,' and subse- 

 quently by myself in my paper on the "Lepidoptera of Japan and 

 Corea," P. Z. S., 1887, when I did not possess specimens of the 

 species. I at first considered it to be merely a local form of 

 L. imziloiy but the following characters are amply sufficient to 

 separate it from that species. In the first place the " pouch " of 

 female of L.japonica is without a keel, and is black instead of light 

 chestnut ; this, without reference to other points of difference, at 

 once distinguishes it ; but it is further much larger in size, the 

 ground colour is darker, and the anal blotch is broader and of a 

 bright crimson. 



With regard to the pouch of L. puziloi, M. Oberthiir is of 

 opinion that this is probably not developed until pairing has
