Froelich, in 1828, refers to this with reserve, and we can well at 

 this distant date let the reference fail as indeterminate, especially as no 

 references to figures or descriptions are given by Fabricius. 



In [1826] in his Verz., Hiibner summarises as follows under 3 

 different Genera. 



^' Aleuuma contaDiinajia. Hiib. Verx., p. 392. (Hiib., Zntr. Turt,, 

 142.)" 



'Amelia rlwmbana. Hiib. Ycrz., p. 890. (Schiff. WV., Tort. D.7 ; 

 Hiib. Tort. 173.) 



"Acalla ciliana. Hiib. Verz., p. 383. (Hiib. Tort. 171.) 



Of these three genera since Acalla was the earliest, and since the 

 three Hiibnerian species are forms of the same species, Acalla is the 

 generic name) which has been adopted for contaminana in Staudinger's 

 Catalog (following Meyrick). But this is another question. Meyrick 

 adopted Acalla, but subsequently dropped it without comment in 

 Wytsmann's Gen. Ins. and Lep.'Cat. for the name Peruuea of Curtis, 

 which in turn may probably have to fall before Oxvjrapha, Hiib. Verz. 



Froelich. Enumer alio Tort. Wart., p. 26 [1828] , points out the 

 raised scales on the wings, etc., and describes and names a new (?) 

 form as T. dimidiana. 



" No. 26. T. contaminana alis anticis retuso-apiculatis pailide 

 flavicantibus rufo-reticulatis ; macula costali fusca, puneto disci niveo, 

 fimbria aiisque posticis albis. 



Hiib., 142. Charp., p. 47. Fabr. Sup., p. 379. Fyr. retictdana (?). 



" L. frequens Elvaci in Pyro sylvestris. July, August. 



" Colore multum variat. Alae anticae jam dilute luteolae jam 

 luteo-testacea fusco aut rufo reticulatae. Macula costalis major 

 minorve, aut rufa aut fusca saepe fasciae-formis marginem internum 

 attingit ad costam interrupta, rarissima nulla. In disco semper 

 punctum niveum e squamis elevatis adest, facile obliterandum." 



" No. 27. T. dimidiana alis anticis retuso-apiculatis brunneo-fufecis 

 immaculatis : puneto disci timbriaque dimidiato niveis, posticis 

 fusco-cinereis. 



" L. rarior in sepibus. October. 



" Habitus et summa affinitas antecedentis {contaminana), et forsan 

 varietas ejusdem ; at serior apparet nee frequens. Figui'a alarum 

 omnino eadem ; anticae fusco brunneae immaculatae, raro strigulis 

 flammeo brunneis, et puneto niveo discoidali elevato notatae, posticae 

 obscuriores cinereae, nee albae. Caput et thorax obscure ferruginea." 



Hiibner. Tort., figs. 299, 300. [1829 or 80.] 



Figs. 299 and 300 are quite the same except that the general 

 coloration differs. In 299 it is of a rich very deep fuscous brown 

 perhaps intended as a reference to the ferruginous basis in many forms 

 {ciliana). The hindwings are also of a corresponding grade of colour. 

 In 300 it is of a fuscous black and the hindwings are of a corresponding 

 grade of colour. The dark shading in both figures are exactly the 

 same in area and shape. These areas are the basal, outer marginal, 

 and a blotch on the costa connected by a costal darkening. Hiibner 

 calls these figures dimidiana. They are certainly not the rhombana of 

 Hiib. 173. 



(To he concluded.)
