to be useless to conjecture to what genus tlie species actually belong. 

 They are not improbably redescriptions of some of our common Ptilo- 

 dontinae. 



9 Exaerrtn lignigera, Walk., p. 423, belongs to lanassa, "Walk., 

 (Xi//iitd(7es, Pack.) and is very probably the 9 of lanassa lignicolor, 

 Wa/k. {XijI. vir/jata, Pack.). 



Edema semiru/escens, Walk., p. 424=Coelodasys unicornis (Smith) 

 Park. 



Edema humilis. Walk., p. 425=:Coelodasys unicornis (Smith) Pack. 

 Edema ? assorJata^ Walk., p. ^2^^^=Cecrita? bilineata. Pack. 



S Edema? fransrersata, Walk., p. 427=Ianassa lignicolor, WalJc. 

 Edema ? plagiata, Walk., p. 427, belongs to Parorgyia, Pack. 

 '• Two approximate rivulous distinct blackish transverse bands between 

 which a whitish patch at base of cell enclosing an incomplete reniform 

 spot which is formed by a black annulus. A white spot before inter- 

 nal angle margined inwardly with a blackish shade. A deeply waved 

 subterminal line ; a narrow terminal line all blackish and indistinct. 

 This is a species of moderate size." P. plagiata, is otherwise unknown 

 to us ; the foregoing descriptive remarks are from our note book. 



Charadra confie/ua, Walk., p. 446=^Diphtera deridens, Gruenee. 

 Since this species cannot be retained in Diphtera, Walker's generic 

 name may be adopted and the species known as Charadra deridens. 

 It is a Noctuid and also described by Walker (ante) as Acron^ct.a cir- 

 cuUfcra. 



We saw no specimens of the genera described on pp. 447 — 451. 

 There appears no proper ground for the construction of any of these 

 •• genera " from the descriptions, and the species are probably known 

 under previous names. 



(Attar us ricin i\ p. 525, belongs to Samia Hiibn. This name is adopted 

 from Boisiluval Ann. Soc. Ent. Fr. 3d Ser. ii. 755, and A. Iiinnla, 

 Walk., (ante) referred as synonymous. Attarus cumingii, Hutton, 

 and Atfartts guerini, Moore, belong also to Samia, all congeneric with 

 S. Cynthia.)

Cijmatophora (!) viride-irem, Walk., p. GOT, belongs to Hadena (?). 



Saligena personata, Walk., p. 606=Raphia frater, Grute. 



Part XXXHT.— 1865. 



Yarnia^ Walk., p. 825. Whether the species from Asia and South 

 America, which are described here with our as yet single species from 

 the United States, are congeneric with it, cannot be decided by us
