20. Cerogama. — -Fore wings light grey, mottled with brown of various shades, trans- 

 verse lines brown. Hind wings yellow, the yellow space between the two black bands 

 being of the same width throughout. Basal third of wing covered with long brownish 

 hairs. Expands about three inches. Found from Montreal to London, but not generally 

 common. 



21. Neogama. — Primaries grey and resembling in their colour and markings the pre- 

 ceding species. The hind wings, however, are very different, the yellow being darker and 

 the space between the black bands irregular in outline. Expands about three inches. 

 Found from Montreal to London. Rather common. 



The variety Communis of this species is somewhat darker in colour, the fore wings 

 have more brown, and the markings are not so distinct, while the ground colour of the 

 hind wings is a dusky buff. It has also been found at Montreal and London. 



22. Subnata. — This is a fine species, closely allied to neogama, but may be distin- 

 guished by its larger size, the brighter yellow of the hind wings, and the greater distinct- 

 ness of the markings on the fore wings. There is a black dash at base of wings, reaching 

 to subreniform spot, which is absent in neogama, The subreniform spot is also open, i.e., 

 formed by the bending inwards of the transverse posterior line. In neogama it is closed. 

 Expands three and one quarter to three and one half inches. Found at Montreal, 

 also at London. 



23. Piatrix. — Primaries brown, varied with darker shades, and with black transverse 

 lines. Secondaries dark yellow, base clothed with long brownish hair. Inner black band 

 reaches to interior margin. This species resembles the preceding, but expands only from 

 two and one half to three inches. Found in Ontario, locality not given. 



24. Palteogama. — Fore wings dark brownish grey, reniform spot dark coloured. 

 Transverse lines indistinct, except the basal line. Hind wings dark buff, outer band wavy 

 near internal margin, inner band much constricted about the middle, and wavy near 

 internal margin. Base of wings clothed with long brown hair. Found at London, where 

 its variety phalanga is also taken. Expands two and a half to three inches. 



25. Habilis. — Fore wings dark grey, with narrow black transverse lines. Hind 

 wings dark buff, space between the black bands narrow and wavy near internal margin. 

 Tnner band ends in a point. Base of wings clothed with dark brown hairs. Very like
