blackish brown central band." \Cidaria] Entephria auvata, 

 Pack., for which no reference is given in Dyar's list, was pub- 

 lished in Proc. Bost. Soc. xi. 51 (1866), and is, as Grossbeck has 

 just shown in some interesting Geometrid notes (Trans. Amer. 

 Ent. Soc. xxxiii. 338) the oldest name for the eastern American 

 species which has been passing for ccesiata, Schiff. Grote's 

 inventaraia will possibly prove a synonym of Entephria aurata. 



5. Cyllopoda jatropharia (Linn.). 



This common species is frequently recorded as Cyllopoda (or 

 Atyria or Flavinia) osiris, Cram., and until recently stood under 

 that name in the British Museum collection. As a result, when 

 the rare form (or close ally) with the broad marginal band to the 

 hind wings turned up in British Guiana, Mr. Warren (Nov. Zool. 

 iv. 420) named it Cyllopoda latimargo, sp. nov. ; whereas a refer- 

 ence to Cramer's figure shows that that is precisely the form 

 which he named osiris, while Clerck's figure (no doubt from the 

 Queen of Sweden's collection) shows with equal clearness that the 

 common form is the PhaUena Geometra jatropharia of Linnaeus. I 

 only know the true osiris from British and Dutch Guiana. The 

 corrected synonymy of the two forms is : — 



(a) Cyllopoda jatropharia (Linn.). 



Phalcena Geometra jatropharia, Linn., Syst. Nat. ed. 10, 523 



(1758) ; Clerek, Ic. ii. tab. 55, 3 (1764). 

 Atyria osiris, auctt., nee Cram. 

 ? Cyllopoda ovata, Warr., Nov. Zool. xiv. 198 (1907), syn. 



nov. 



(b) Cyllopoda osiris (Cram.). 



Phalcena osiris, Cram., Pap. Exot. ii. 28, tab. 115 e (1777). 

 Cyllopoda latimargo, Warr., Nov. Zool. iv. 420 (1897). 

 Cramer himself was the first to start the confusion, for on 

 p. 151 he sinks his own species to that of Linnseus. 



6. Semiothisa regulata (Fabr.). 



Guenee (Spec. G6n. x. 68) readily recognized the Phakena 

 regulata of Fabricius as " certainement de ce genre " {Macai-ia= 

 Semiothisa), but was unable to decide to which of the many 

 American species it should be referred. I have examined the 

 type in the Banksian collection, and find it is the common 

 species which Guenee himself named c«o<a<a. The following will 

 be a suflicient synonymy : — 



Phalcena regulata, Fb., Syst. Ent. 629 (1775). 



P. notata, Stoll, in Cram. Pap. Exot. iv. 160, tab. 371, g, h 

 (1781), nee Linn. 



Macaria enotata, Guen., Spec. Gen. x. 69 (1858).
