Boarmia montanaria, sp. n. 



Primaries brown ; first line blackish, slightly curved and 

 preceded by a fuscous transverse shade ; second line blackish, 

 angulated below costa, thence oblique to inner margin ; 

 between these lines the costal area is filled in \yith pale 

 brown ; submarginal line whitish, preceded by a fuscous 

 shade, which is broadest below the angle of the second line 

 and almost fills up the space between this line and the sub- 

 marginal ; discal spot black and curved, its extremities 

 touching the blackish central shade and forming an annu- 

 lated mark. Secondaries grey-brown, striated and powdered 

 with darker brown ; the central line is indicated by a series 

 of black dots on the nervules ; there is an oblique dusky sub- 

 marginal streak and the anal portion of the indistinct pale 

 submarginal line is also bordered inwardly with dusky. 

 Fringes brown, marked with darker at extremities of the 

 nervules and preceded by a black lunulated line. Under 

 surface greyish, darker on apical area of primaries, and tinged 

 with ochreous on the costal area between the transverse lines ; 

 this last and also the discal spot are rather indistinct.

There were specimens from Ohoyama and Yesso in Fryer's 

 collection. 



I obtained a specimen at Nagasaki in May, one at Hako- 

 date in August, and one at Nikko in September. Mr. Smith 

 took this species at Ilakone in August. 



B. lumfera, Butl., is identical with the dark form of 

 B. rohoraria, which Staudinger has named var. I'n/uscata. 

 B. arguta, Butl., is also a form of B. rohoraria in which the 

 transverse markings are well defined and conspicuous.
