however, tells me that he onee saw thousands of 2^isana in a field in 

 which peas had been grown the year before, and that there was not 

 one so dark as Haworth's nigricana among them ; the question may, 

 therefore, still be considered open for further investigation. 



One thing, however, is very certain, that so far from being scarce 

 in the perfect state, as Wilkinson affirms, they ai'e exceedingly abun- 

 dant on the sunny side of hedges adjoining the previous year's pea 

 fields, and at the edges of woods where Orohiis and other vetches are 

 common. 



Dr, Wocke (in Stand. Cat.) sinks ^jroav'wff;m, Wilk., as a synonym 

 of tenehrosana, Dup., making nirjricana, Steph., ?L\\di pisana, Gn., syno- 

 nymous with the next species, nehritana, Tr. As this is an error, 

 pr'oximana, nigricann, andpisana being all synonymous with tenehromna, 

 Dup., this last name will have to be dropped in favour of nigricana, 

 Steph., which has the priority. 



E. Oermarana, Hiib. (pnncticostana, Steph., "Wilk., Doubl.). — A 

 small species, recognizable at once by its yellow face and palpi, and by 

 the narrow, shining, blackish-brown fore-wings, with numerous short 

 yellow costal streaks. 



Dr. "Wocke (in Stand. Cat.) calls this Germmana, quoting Hiib- 

 ner's first name, which seems to have been accidentally thus printed ; 

 but as Hilbner afterwards corrected it himself, it seems an abuse of 

 the law of priority to insist on retaining it instead of Germarana. 

 "Wocke quotes atropurpurana of Haworth and Stephens, as well as 

 immaculana, Gn., as synonyms of this species. 



Before quitting this group, it may be as well to refer to one more 

 species which is exceedingly apt to be mistaken for a Dicroramplia, viz., 

 GraphoUta nUcetann, of which, small dark examples are constantly to 

 be found mixed with them in collections. This may, however, nearly 

 always be distinguished by the large brownish-grey ocellus which oc- 

 cupies nearly the whole of the apical third of the fore-wing, and 

 contains several black lines.
