144 Lord Walsingham 07i 



gined externally by silvery white. The equilateral triangle formed 

 by the apical portion of the wing is tinted with fawn-colour, and con- 

 tains two pairs of rather wide silvery white costal streaks, between 

 which and also at the apex of the wing the fawn-colour is somewhat 

 more intense. The cilia are white ; an ocellated patch above the 

 anal angle, enclosed at the sides by silvery white, contains a few 

 jet-black dots. Hind wings dull brownish, with greyish white 

 fringes. Expanse, 14 mm. 



Four specimens. Arizona. 



? Semasia helianthana, Eiley. 



A single female from Arizona agrees with Eiley's de- 

 scription, except in the absence of a basal shade on the 

 fore wings. I am not confident that it is correctly 

 identified, as I have never seen specimens of this species. 



Peoteopteryx, Wlsm. 



Proteopteryx emarginana, Wlsm. 



One male and one female. Arizona. 



These specimens have no clearly defined dorsal patch, 

 as have nearly all my Californian varieties, but are dis- 

 tinguished by a waved umbreous streak reaching from 

 the apex nearly to the middle of the wing, nearer to the 

 costal than to the dorsal margin. The costal fold also 

 seems to be somewhat more conspicuous and more closely 

 appressed in the male ; but it would not be safe to sepa- 

 rate it from a species exhibiting so wide a range of 

 variation upon the evidence of such slight differences in 

 two specimens only. 



Steganoptycha, Steph. 



Steganoptycha sp. 



This is the same species as that which stands in 

 Fernald's catalogue as S. incarnana. Haw., on the 

 authority of a specimen collected by me in California, 

 and recorded in Cat. Lep. Het., B. M., part iv. Six 

 specimens now received from Mexico lead me to believe 

 that it is really distinct from that species. All are alike 

 in having a narrower central fascia than the European 

 form of >S'. incarnana, as well as in some minor differ- 

 ences. A further examination of other allied species is 

 necessary before I shall be justified in describing it under 

 a new specific name.
