jjinastri ; SC- and R' of hiiidwiug from upper angle of cell, very shortly stalked 

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



S. The lobes of the tenth sternite broader and shorter than in pin. pinastri. 

 The npi)er process of the harpe (PL XXXVIII. f. 12) flattened, not rolled in to form 

 a cylinder, shorter than in pii>. j/inastri, 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.

S ? . Differs from pinastri, a}iart from colour, chiefly in the following points : 

 forctibia with fewer spines, midtibia without any spines 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 //alf 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 with two processes, but both 

 shorter, the ujiper one branching ofi'from the dorsal margin of the other. 



?. Vaginal ])late 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 j/inastri, individually 

 variable. 



Larva and pu])a not known. 



Hah. Japan and China. 



Two subspecies. 



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

 character.

 (PI. XXXVIII. f. 14) long, curving ujiward at end. Apical process of penis-sheath 

 longer than in pinastri.
