probably this form is another coast species, apparentl)' bearing the 

 same relation to the wood species, jimctella, that the new coast 

 species, hlandulella, does to the wood species, macnlea. This is 

 only thrown out as a suggestion for future investigation. 



I may add that Mr. Nelson Richardson has sent me a lovely 

 bred series of Lita leucomellanella from Weymouth. The white 

 markings, upon which Mr. Stainton relies very much, are very 

 variable, and in some almost obsolete. I believe this is the only 

 genuine difference between leucomellanella, and the closelj^-allied 

 vicinella. I see, too, that many of our micro-lepidopterists 

 bracket vicinella and leucomellaitella together, thus suggesting 

 that they ai'e but one species, and that viciiiella is an obscurely- 

 marked form of leucomellanella. Is this the reason ? If not, 

 will one of them kindly tell us why they are thus bracketed ? 



Pale semidecandriella are not liable to be confounded with 

 marmorea, if care be taken. The best point of distinction 

 seems to be, that in marmorea the dark shade which takes up the 

 costal part of the anterior wings is continuous to the thorax, 

 while in semidecandriella it does not extend beyond the dark 

 oblique line, the basal part being unicolorous grey. 



The order in which our British species of this group are 

 arranged does not seem altogether satisfactory. The new species 

 hlandidcUa is closely allied to niaculea and huhneri, and leuco- 

 mellanella seems rather out of place ; but it seems difficult to 

 determine with which species its affinities are greatest. I have 

 adopted the following as being an apparently more natural 

 arrangement in the species of this group : —costclla, fraternella, 

 vicinella (?), leucomellanella, tricolorella, junctella, hlandulella, 

 maculea, huhneri, knaggsiella, maculiferella, semidecandriella, 

 marmorea. Of course it is open to objection, but less so it 

 seems to me than the present arrangement.

Referring to my contention that Lijaena icarus, L. hellargus, 

 and L. corydon are not pure species, Mr. Tutt {ante, p. 257) says, 

 " I believe the differences between any two of these three species
