Hab. -Hokkaido (Sapporo), Honshu (Aomori). 



F. P. - Gydonia vulgaris, Malus pumila ? 



Nom. Jap. - Nishiya-watamushi. 

 This species much resembles in appearance Prociphilus bumeliae Sehr., 

 flying together with it in the latter part of September or in the be- 

 ginning of October, but it may easily be distinguished from it by the 

 much smaller body and very short antennae. The life-history of this 

 insect is not yet kown; it may live most probably on the root of the 

 apple-tree, sent by Mr. J. Nishiya of the experimental Station at Ao- 

 mori as zoatamushi; I have caught this insect also on Gydonia vulgaris. 



8. Gen. Nishiyana n. gen. 



Nearly allied to Prociphilus Koch. 



Head with 2 oval waxgland's plates; antennae somewhat longer than 

 the head and thorax together, the 3rd joint longest, subequal to the 

 4th and 5th combined, the latter clavate in form, the 4th dilated in 

 the middle and the shortest, the 5th and 6th fusiform, anterhinarial 

 about 1/3 the length of the postrhinarial, and somewhat narrower than 

 it, each joint, except the first 2, with narrow imcomplete rings on the 

 under surface; wings long, more than twice the length of the body, 

 stigma very long, lanceolete, stigmatic nervure opening rather nearer 

 the apex, media simple, at the basal half obsolete, the first 2 obliques 

 separated at the bases; hind-wings with 2 obliques, not widly separated 

 at the bases, cubitus where the obliques open strongly incurved, with 

 3 booklets on the costa; legs moderately long, tibiae much narrower 

 than the antennae.
