Described from five specimens (3 males and 2 females) reared 

 from stored grain at Yokahoma, Japan, and named in honor of 

 Prof. Kuwana, from whom the specimens were received. In 

 superficial characters it resembles very closely Martyringa lati- 

 pennis Walsingham, but is easily distinguished by the structural 

 characters. A specific description of the pupa and larva follows: 



Pupa. 10-11 mm. long; abdomen pale yellow, darker on dorsum; wing 

 cases and dorsum of thorax yellowish brown; head yellow; cremaster black; 

 spiracles small, rounded-oval, edges strongly pigmented, brown; proleg scars 

 conspicuous, not pigmented. 



Larva. Full grown 22-23 mm. long by 2-2.5 mm. broad. Body sordid 

 white, irregularly spotted with white at places of muscle attachment. Pro- 

 thoracic shield, prespiracular shield of prothorax and prothoracic chitiniza- 

 tion about seta group VI evenly dark brown; a small brown anterior, dorso- 

 lateral, chitinized spot in intersegmental area on each side of mesothorax, 

 bearing a minute seta; chitinized area about tubercle Ib of mesothorax 

 slightly brownish; chitinized areas about tubercles otherwise unpigmented, 

 small; tubercles pale; setae very long, slender, whitish yellow; anal shield 

 yellowish brown; chitinized areas of thoracic legs brownish yellow shading 

 to darker brown, blackish on front margin of coxae, claws pale brown. Spir-
