WARO NAKAHARA. 



Prothorax with a rather broad fuscous stripe on each side. Mesotho- 

 rax sulphurate yellow, striped with brown on each side. 



Legs pale ; tibiae I and II somewhat darkish ; tibia III darkish at apex; 

 tarsal joints of all legs variegated with ochraceous yellow. 



Forewing rather broad, moderately rounded at apex, hyaline ; hind 

 marginal area with alternate streches of pale and fuscous ; a darkish streak 

 exists in the space between ist and 2nd radial sectors, beyond inner 

 gradate series ; neuration pale yellow, marked rather evenly with brown; 

 gradate veinlets fuscous black, narrowly margined with fuscous. Costal 

 area very broad, but not over five times the length of veinlet connecting 

 subcosta and radius; costal crossveins furcate; three radial sectors. In the 

 type specimen the third sector of right wing gives off four branches be- 

 fore outer gradate series, while on the left wing the second sector is forked 

 before inner gradate series and the third shows only three branches before 

 outer gradate series ; median slightly bunt toward cubitus at connecting 

 veinlet. 



Hindwing hyaline and colorless ; neuration pale yellow, anal veins 

 terminally blackish ; radial sector with three branches before outer gradate 

 series. 



Abdomen darkish yellow on both dorsal and ventral sides. Female 

 has stout subgenital plate, which is, when seen from below, tongue-like in 

 shape. 



Measurement : 



Length of body 7 mm. 



Length of forewing 1 1 mm. 



Width of forewing 4.5 mm. 



Length of hindwing 9 mm. 



A single female specimen captured by Mr. A. Nohira at Akakura, 

 Prov. Echigo, on August 3, '14, is in my collection. 



Remark : This species is of much interest on account of its close re- 

 semblance to Megolomus in several respects, f. i. in the very broad costal 

 area of forewing, etc.
