BTBTJOOltAPHY. 307 



pointed out at the South London Meeting (January 22nd), there is 

 every phase of development in both species, and this scientific-looking 

 phrase is utterly unreliable. My note has proved how easy it is to make 

 a storm in a teapot, and how ready some lej^idopterists are to write on 

 any subject whatever. I still maintain that my specimens may be 

 equally well-named as either species ; and that, although " recent study 

 may have disclosed that iyY)\cdi\ fasciunaila are red above and ochreous- 

 fuliginous below," whilst " typical sfrigilis are differently coloured above 

 and fuliginous-grey below," there are specimens of which 1 confess I 

 know nothing, and about which lepidopterists in general certainly know 

 less than I. — J. W. Tutt. February, 1891.

Additions to the British List and Changes in Nomenclature. 



Lepidoptera. 



Ephestia roxburghii, Gregs. This unfortunate species gets variously 

 placed by different authors. Ragonot considered it a valid species ; 

 Hulst, in his recent (1890) work on the Phycitidce of North America, 

 places it as a synonym oi Plodia interpunctella, Hb., giving the genus 

 Plodia as distinct from Ephesfia ; and now Mr. Barrett {E.M.M., p. 

 49) says it is a melanic form of E. elutella. Presumably Mr. Barrett is 

 right, and so we must now write Ephestia elutella var. roxburghii. 



In Mr. Hulst's monograph, Ephestia kiihniella is quoted from North 

 Carolina, New Mexico, Colorado, and Canada. It seems as if it were 

 really a native of the Western States of America, after all. 



Sericoris lacunaiia v. hoffinanniana, C. A. Teich, Warren, Entom., 

 34 (under Fenthina). This is a variety recently described from the 

 Baltic, which Mr. Warren identifies with the Cambridgeshire fen form. 



Hemiptera. 



Aleurodes filicium, Goldi., J. W. Douglas, E.M.M., 44. A Brazilian 

 species found on ferns in the fern house at Kew Gardens, of course 

 imported. 



Diptera. 



Homalomyia vesparea, n. sp., Meade, E.M.M., 42, Newstead, /.r., 

 41. Bred from larvae found in nests of Vespa germanica in Cheshire. 



Mydcea affinis, n. sp., Meade, E.M.M., 42. Lake district. 



Limnophora litorea. Fin., Meade, E.M.M., 43. Grange-over-Sands, 

 Lancashire. 



Arachnida. ^ 



F. O. Pickard - Cambridge. Descriptive notes on some obscure 

 British spiders. Ann. Mag. Nat. Hist., January. A synoptical table 

 of the genera of the group Linyphini is given, and on p. 78 Lepiy- 

 phantes pinicola, Simon, is added to the British List, while on p. 80 a 

 new species is described as Tmeticus niger. Both these spiders were 

 taken on Helvellyn. — T. D. A. Cockerell. 



' Arachnida are not insects, but as Mr. Cockerell wishes the Bibliography of 

 the Order to appear I have included them. — Ed.
