me by Mr. (irossbeck. My specimen was bred by Mr. I". N. Williny 

 from n green caterpillar with faint whitisli lines, found on currant at 

 Regina. I'he caterpillar pupated 12th June, 1905, and the moih emerged 

 on the 28th of the same month. 



M. ethela. Dr. Hulst's second new species, is a very well marked 

 form, and is perfectly constant. It is distinguished from all the others of 

 the heniliata grou|) by having the space between the basal and intradiscal 

 lines on the fore wings cream-coloured. The contrast between this hand 

 and the ilark central fascia is very striking, and the moth is a most beau- 

 tiful one. M. ethela was described from Nevada, but all my specimens 

 are from Hritish Columbia. 



IJeside these forms, I have five others, all from British Columbia. 

 Four of these I consider to be good species, and I will describe them as 

 such. To the fifth I have given a varietal name. They all of them so 

 evidently belong to the hersiliata stock that I shall describe them by 

 comparing them with the typical form, which is sufficiently well known. 



MeioUuca occidentata, n. sp. — E.xpanse, 29-30 mm. This is more 

 like the typical hersiltnta than any of the species following. The style of 

 coloration is the same, but the slight differences to which I shall call 

 attention seem to be constant. 



The outermost of the two basal lines on the fore wings leaves the 

 cosla at a sharp angle, so that if it were continued in the same direction 

 as that in which it runs to the subcostal vein, it would cut the hind margin 

 of the wing. The basal area also is much larger, and the two parallel 

 basal lines are more distinct than in hersiliata. 



The central fascia is not narrowed (juite so much below vein i as it 

 usually is in hersiliata. The rust colour which pervades the submarginal 

 band in hersiliata is much reduced in occidentata, and the central fascia 

 is of a darker colour in the last-named species. 



The hind wing in occidentata is comparatively clear, but the discal 

 spot is distini t, and the very heavy extradiscal line of the under side is 

 reflected. 



On the under side all the markings on both fore and hind wings are 

 heavier than in hersiliata, especially the extradiscal lines, and the space 

 within these lines is darker than that without. 



This species is described from seven specimens in my collection, 

 taken at \Vellingt«)n and Departure Hay, on Vancouver Island, and at 

 Salem, Oregon. The dates are ifih June to 25th July.
