76 THE ENTOMOLOGIST. 



of larvae, I think entomologists would accept it as a species with 

 better grace ; but until then entomologists have a perfect right to 

 be cautious in admitting E. curzoni to specific distinction. For 

 m3'self, I cannot see so great a difference between the nanata type 

 and its var. curzoni as between the typical Noctua glareosa and its 

 Shetland form, and certainly not more than between the type 

 Melanijjpe montanata and its var. shetlandica ; yet no one has 

 attempted to raise them to specific distinction. The genus 

 Eujnthecia appears peculiarly unhappy in this respect. Being 

 rather more obscure than the other genera of Macro-Lepidoptera, 

 it seems that certain collectors try experiments on it, which could 

 not perhaps be carried out on other genera with the same chance 

 of success.— J. TuTT ; 45, Beaconsfield Terrace, Greenwich, S.E., 

 February 2, 1885. 



EuPiTHECiA CURZONI. — The only specimens of the Shetland 

 " P"n " I ^^^^ ^^ ^^'' ^^PPer's I pronounced at once northern 

 forms of E. satyrata ; there is something, to a trained eye, that 

 cannot well be described. As to its being, as Mr. Gregson says, 

 the narrow-winged " pug," that is out of the question. Some 

 thirty years ago, on the bank at Witherslack, I took what I 

 thought to be a new " pug," a shining light leaden-coloured 

 " pug." I sent them to Doubleday, and he wrote me that they 

 came near to the Norwegian form of E. satyrata (then callunaria). 

 Since then the species, at the same place, partakes more of the 

 characters we get in the woods at Grange ; the larva always on 

 the ox-eye daisy flowers. My Scotch E. callunaria have all the 

 characters of the Shetland species, only not so extreme in 

 variation. But consider how different are the Shetland forms 

 of Noctua glareosa, — whilst these are black, ours are lilac- 

 coloured. — J. B. HoDGKiNSON ; Preston, July 11, 1885. 



Scientific Nomenclature. — Since the publication of ray 

 remarks on scientific nomenclature, in the February number of 

 tlie ' Entomologist ' (Entom. xviii. 4G), it has been pointed out to 

 me that the form in -ensis is employed, as a rule, only for adjectives 

 derived from names of places, and that gregsoniana is the correct 

 adjectival form in Latin of Mr. Gregson's name. His recent 

 discovery should therefore be named Eupithecia curzoniana. 

 Having received a letter from Mr. Gregson to the effect that the 

 statement "anything will do for a name" does not occur anywhere
