near the base, and in the costal area ; underneath the wings are paler; the 

 primaries have nearly the same marks as above but more conspicuous ; on 

 the secondaries the angular band is surmounted by another irregular spot, 

 so as to form two contiguous spots, or rather one large irregular didymous 

 one. 



[Quite common in Canada.]

421. Alypia Mac Cullochii Kirby. — Plate iv., fig. 5. — Expansion 

 of wings 1 yi inch. Taken in Nova Scotia by Dr. Mac Culloch, and in 

 Canada by Dr. Bigsby. 



Body and wings very black. Orbit of the eyes externally clothed with 

 white hairs ; base-covers or tippets whitish ; primary wings with three very 

 white spots, one near the base oblique, obversely wedge-shaped, divided 

 into two by a longitudinal black line ; next, at a little distance from the 

 anterior margin, is a subtrapezoidal, small, white spot, between which and 

 the posterior margin is an articulate band, abbreviated at each end, of the 

 same colour, consisting of six spots divided by black lines ; the same 

 spots distinguish the under surface of these wings, and besides there is a 

 whitish longitudinal one in the costal area ; in the secondaries are also 

 three white spots on both surfaces, viz., a large rectangular one near the 

 base divided longitudinally into four ; a longitudinal undivided one at the 

 anterior margin ; and an articulate posterior abbreviated band, divided 

 into five spots ; the longitudinal costal streak may almost be regarded as 

 forming a sixth, as the lower end is parallel with the last spot of the band ; 

 the four anterior legs are externally covered with long orange coloured 

 hairs, which character is slso found in A. ociomaculata.

[302.] Body ash-coloured ; thorax with a large trapezoidal brown spot 

 dilated next the abdomen ; primaries angulated, ash-coloured, with a 

 transverse series of brown submarginal crescents in a paler band, between 

 which and the posterior margin is another obsolete paler one ; above the 

 crescents is a straight whitish band, and a linear angular forked one under 

 the internal sinuses of which the wings are clouded with dark brown ;
