Note. — mercuriana has been wrongly attributed to Hiibuer as its 

 author. It was figured in Greyer's continuation of Hiibner's work, 

 and the accompanying test, dated " September, 1830," is by Dr. 

 Frolich. On p. 11, after the Latin description, we find the following 

 reference — " Froel. En., p. 73, n. 170," which proves that the text was 

 published after Frolich's " Enumeratio." Although the title accom- 

 panying the text is dated 1830, it seems that this and the corresponding 

 plates were not published until April, 1831, for in the copy of 

 Hiibner in the Merton Library is the following note, evidently written 

 at the time : — 



"en Avril, 1831, reQu une partie de texte, et 4 planches nouvelles qui sont les 

 49, 50, 51 et 52e." 



And below this is written with a different pen — 



"du 20 Mars, 1834, re9u la pi. 53." 



Jacob Hiibner died on the 13th September, 1826. 



DlCURORAMPHA PLUMBAGANA, Tr. 



In Staudinger and Wocke's Catalogue, under the name distinctana, 

 Hein. (No. 1282), and again under subsequana, Hw., we find the two 

 following references : — " ? plmnhagana Wlk. 107 ; ? Stt. Man. 2. 215." 

 Why they are inserted in either of these places is not apparent, unless 

 having made tanaceti, Stn. (which is a good species) a synonym of 

 plumhagana, it was necessary to locate plumbagana, Wilk. and Stn., 

 elsewhere, and being unable to find a satisfactory place, they were 

 referred with a " ? " to the species which precedes and the species 

 which ybZZoiws plumhagana in the Catalogue ! 



Both Wilkinson and Stainton were rightly acquainted with plum- 

 5«y(7««, Tr., and to that species these two references must be removed. 



DiOHEORAMPHA MONTANANA, Dp. 



"We have now eliminated from the subsequana of Staudinger's 

 Catalogue all but three references, which constitute two good species.
