NEPTICULA ANOMALELLA, G6ze, AND NEPTICULA FLETCHERI, 11. Sp. 



Under the name N. anomalella, Goze, there appear to have been 

 for about a hundred and fifty years two distinct species united. These 

 may, for convenience, be called the " red-headed " species = anoma- 

 lella, Goze, and the "black-headed" species, for which we propose 

 the name fletcheri, in compliment to Mr. W. H. B. Fletcher, who has 

 at last separated the two forms. He writes of these : (1) The " red- 

 headed " form occurs everywhere, it seems, in wild roses, Rosa canina 

 and R. rubiginosa, in hedgerows, and in sundry species of garden roses, 

 e.g., I have met with it in R. indica var. rugosa rarely, in R. seirvper- 

 virens in swarms, and in the ordinary " H. P." and "tea" roses. 



(2) The " black-headed " form is very common, but not so ubiquitous 

 as the previous form. I find it here and in Lincolnshire, in Rosa 

 arvensis. It is a much more covert-loving species than the other (it. 

 arvensis, has, of course, the same habit). Comparing the two forms 

 he notes : (1) The frass seems to be more diffusively disposed in the 

 mine of the "black-headed" form ; in the "red-headed" form it looks to 

 the naked eye like the line drawn with a ruling-pen. (2) The 

 difference in the colour of the head of the imagines is not sexual. 

 I have a long, carefully sexed series (50-60 specimens) of each. 



(3) The "black-headed" form is decidedly the smaller. (4) I 

 can breed the "red-headed" form pure in any quantity, and I think 

 I can also breed the "black-headed" form quite pure (in Utt.). 

 In the Zoologist, vol. xi., p. 3959 (1853), Stainton writes that " from 

 the mode of mining and the colour of the cocoons, there is little doubt 

 that two species feed on the rose, one of which has always been 

 confounded with JV. rujicapitella (see Lewis in Ent. Mag., i., 422), but 

 of which one sex has the tuft of the head black, was observed by 

 De Geer, and Goze has given to his insect the name of N. anomalella. 

 The other species, which I have not bred, may be the Continental N. 

 centij'oliella." Here Stainton possibly, unknowingly, mixes three species, 

 two of which he considers as sexes of one species (the one that has 

 been mixed with N. rujicapitdla, and which Goze has called anoma- 

 lella). We find, further, that in the Insecta Britannica, p. 297, Stainton
