34 BULLETIN OF THE BROOKLYN ENT. SOO. 



This is allied to Hecla, Lefvr., Meadii, W. H. Edw., and Boothii, 

 Curl, but is nearer, in all save its greater size, to the first, and may be 

 a variety of it, as is Christina. W. H. Edw., of the Labrador Pelidne, 

 Bdl. It further differs from the Greenland and Lapland forms of 

 Heda in the shape of the wings, especially in <^\ in the much greater 

 presence of blackish scales on upper surface, and in the absence of 

 the paler green border of under side of secondaries in 0. Whether 

 these and minor points will hold constant in a series is vet to be seen, 

 and is in all probability doubtful ; the present descriptions are from 

 1 r^ and 2 9 9 > a * ew more were taken, but these are all I have 

 had the opportunity of examining. 



They were captured by Esquimaux a considerable distance above 

 Fort Churchill on west coast of Hudson's Bay ; with them was also 

 received a very beautiful form closely allied to Golias Nastes, which I 

 here describe as 



Colias Moina. rf size and form of Nastes, Boisduval. Upper 

 surface bright brimstone yellow, with the slightest tinge of green ; 

 black markings as in Nastes, but much more intense and distinctly 

 defined. Discal spot rather large and deep black. Fringe roseate. 

 Under surface bright pale pea-green, inclining to emerald or verdi- 

 gris green ; a little pale on disc of primaries. On both wings a row of 

 conspicuous dark-brown or blackish spots run parallel with the ex- 

 terior margin at the same distance therefrom as is the inner edge of 

 the dark borders on upper surface. A small white discal spot ringed 

 with black on primaries ; a white one on secondaries, which is largely 

 bordered on costal exterior and inner edges with red, brown, or ma- 

 roon colour, but is open towards the base of wing and emits a pale 

 ray, which extends along within the discoidal cell. Fringes rosy. 



9 same as <$, with the exception of the upper surface being a 

 trifle paler in colour. 



Described from a large number of examples mostly males. 



This, which I presume is but a variety of Nastes, still differs deci- 

 dedly from the Labrador examples in the brightness of the yellow 

 colour and the depth and sharpness of the black markings of upper 

 surface ; and beneath in the beautiful light lively colour, which in 

 the typical Nantes is dull olivaceous and heavy, and in the promi- 

 nent row of dark sub-marginal spots which are entirely wanting 

 in the secondaries and only indicated on primaries by a few indis- 

 tinct dots. 



Further, the 9 °f Nastes is white or greenish white, whilst in the 

 present form it scarcely differs in its yellow colour from the $.
