Boarmia decolor aria, sp. n. (PL VII. fig. 4.) 



Male. Whity brown, finely powdered with darker brown. 

 Primaries have a brownish basal band (sometimes only 

 represented by a spot on the costa and a dot on each nervure 

 below it) ; a dark brown serrated central band commencing 

 in an angular mark on the costa, represented by dots on the 

 nervules, and terminating in an oblique dash on the inner 

 margin ; submarginal band dark brown, irregular in width 

 and externally edged with whitish, as also is the central 

 band ; there is also a brownish spot on costa between basal 

 and central bands, from which a dark shade is sometimes 

 projected to the wide portion of central band. Secondaries 

 have three brownish transverse bands, the first nearly straight, 

 the second narrow and attenuated, and the third of irregular 

 width, the last two edged externally with whitish. All the 

 wings have a blackish discal spot. Fringes brown, preceded 

 by dark brown lunules between the nervules. Under surface 

 of primaries fuscous brown, except the outer and inner 

 margins, which are whity brown ; of the secondaries whitish, 

 sprinkled with brown scales ; a blackish discal spot on each 

 wing, but only the primaries have the transverse markings, 

 and these are not always clear. Antennae broadly bipectinated. 



Female. Generally paler than the male, and the under 

 surface of all the wings is usually whity brown, powdered 

 with brown scales (this is also the case in some males) ; the 

 antennae are simple. 



Expanse, $ 40-45, ? 36-42 millim.

There were a few specimens from Oiwake in Pryer's 

 collection, and I have received one example of each sex from 

 Mr. Manley, who took them at Yokohama. 



The Japanese specimens are rather larger and more strongly 

 marked than European examples. 



Distribution. Europe; Japan.
