])inastn ; SC- and K' of biiulwiiig from njjper angle of cell, very shortly stalked 

 together, the stalk mnch shorter than in pin. pinastri. 



$. The lobes of the tenth sternite broader and shorter than m pin. pinastri. 

 The upper process of the harpe (PI. XXXVIII. f. 12) flattened, not rolled in to form 

 a cylinder, shorter than in pin. pinastri, the lower process more horizontal, more 

 curved at end. Process of penis-sheath (PI. XXVIII. f. 49) remarkably different, 

 being short, strongly curved at end, pointed, almost hooked. 



Hab. Japan.

 Lejiidoptera, of which the sjiecial locality was not given.

c? ? . Differs from pinastri, apart from colour, chiefly in the following points : 

 foretibia with fewer spines, midtibia without any sjiines except some minute apical 

 ones, which are sometimes also wanting, first metatarsal segment shorter than the 

 tibia and as long as the four other segments together, long apical spur of hindtibia 

 less than /talf the length of the first tarsal segment ; antenna proportionately 

 longer ; hindwing less elongate. 



c?. Tenth abdominal tergite (PI. XXVIII. f. 19) longer and much narrower than 

 in pinastri ; sternite sinuate, not completely divided mesially. Clasper more 

 rounded ; harpe (PI. XXXVIII. f. 13. 14) as in pinastri wiih two processes, but both 

 shorter, the upper one branching off from the dorsal margin of the other. 



? . Vaginal plate as in pinastri with a prominent lobe in front of the vaginal 

 orifice (PI. XXI. f. 7. 8), the lobe longer and narrower than in pinastri, individually 

 variable. 



Larva and pupa not known. 



Hab. Jajjan and China. 



Two subspecies. 



The paucity (or even absence) of spines on the midtibia is a very remarkable 

 character.
