They arc in i)r)or condition, most of the markings being obscured, but 

 the extrabasal b.ir is «|iiite distinct and perfectly black instead of red or 

 yellow. The cxtradiscal lines on the fore wings above are also distinct, 

 very fine and black. In other respects these specimens resemble ilie 

 variety mutata. 



The black extrabasal bar readily distinguishes this forni from any 

 other I have seen. 



Meiolfuca Cas/oata, n. sp. — Expanse, 30 mm. \N ings longer and 

 narrower than usual in the case o^ hersiliatiX, and the colouring is duller 

 than in that species. 



The extrabasal bar is dull brown, and fills the .space between the 

 extrabasal and iniradiscal lines. The intra- and extradiscal lines are 

 scalloped, but the scallops are more angular than in hersiliata. 



The submarginal white scalloped line is very distinct, and is parallel 

 to the margin of the wing throughout almost the whole of its length, not 

 being dislocated below the costa as in hersiliata and occidentata. A dull 

 brown band precedes this line, and is continuous right across the wing. 

 'I'he margin of the wing beyond the submarginal line is blackish-gray like 

 the central band. 



Ik'lween the extradiscal line and the submarginal brown band there 

 is a light blotch on the costa, followed by an almost black costal spot and 

 a subapical streak. 



This seems to be the foim representing heniliata in the Kootenay 

 district. My three specimens are all from Kaslo (.Mr. j. W. Cockle). 

 My lightest specimen shows an approach to M. tthela, and I suspect it 

 was a specimen of this form that led Dr. Dyar to suggest that possibly 

 ethela and htrsiliata might be found to intergrade.
