192 [August, 1898. 



and the Zoological Record does not give the exact date. It could, however, hardly 

 have been published in 1895, for on the reverse of the last page is a reference to 

 " Kneuckers Allgem. bot. Zeitschrift Jhrg., 1896, Nr. 3." 



A few notes upon the different species described may perhaps be useful, 

 although a critical review was scarcely intended when commencing this reference to 

 the work before me. 



Trichoptilus ochrodactylus, Fish. 



I have a specimen from Arizona, and it suggests a comparison with centetes, 

 Meyr. (? = oxydactylus, Wkr.), a species which occurs in the West Indies, and 

 which shows very slight variation throughout what appears to be a somewhat cos- 

 mopolitan range of distribution. 



Trichoptilus lohidactylus, Fitch. 



Fernald regards califoraious, Wlsm., as a synonym. I have the darker form 

 from Colorado, and in spite of the colour which makes them look very distinct (the 

 Californian series showing no dark varieties), I am not prepared to dispute his 

 opinion without further study. This species also runs very close to oxydactylus, 

 Wkr. (Ceylon). 



Oxyptilus periscelidactylus, Fitch. 



Fernald omits to recognise in this the genus Sphenarches, Meyr., to which it 

 undoubtedly belongs [vide Wlsm., Pr. Z. Soc. Lond., 1897, 57]. 



Oxyptilus tenuidactylus, Fitch. 



My suggestion that this is nigrociliatus , Z., is here confirmed, and it is recorded 

 that it feeds on blackberry. 



Platyptilia, Hb. 



The author follows Meyrick and myself in uniting Platyptilia, Hb., and 

 Amhlyptilia, Hb. 



Platyptilia pica, Wlsm. 



This species also occurs in Vancouver, whence I have lately received it from 

 Dr. Fletcher. 



Platyptilia acantliodactyla, Hb. 



Fernald records a single specimen from New York. Intermediate varieties 

 between this and cosmodactyla, Hb., undoubtedly occur, and it is very hard to 

 separate these two species with any certainty in a long series of captured specimens 

 from various localities. Both forms seem to me to be included among my specimens 

 from California and Oregon, although Dr. Jordan, Ent. Mo. Mag., XYIII, 117 

 (1881), confirmed my identification made at the time. The last word has not been 

 heard upon the subject, and it would not surprise me to find that at least three 

 distinct species are included in our American series ; I bred one of the many varieties 

 from Orthocarpus in Oregon. 



Fernald's figure of cosmodactyla (PL IX, 1) and Hofmann's figure of acan- 

 thodactyla (Pi. Ill, 5) might well have been taken from the same species. 



Platyptilia carduidactylus, Eiley. 

 The author has here restored the original mongrel name which was corrected 

 by Zeller to cardui. Would he also justify the retention of millieridactylus, Bruand, 

 hritanniodactylus, Grregs., and schmidtiiformis, Freyer .''
