NOTES ON THE MICRO-LEPIDOPTERA OF SOUTH-WEST LONDON. 151 



to the lanes and hedgerows, and Ealing Common has been improved 

 far beyond the needs of the entomologist. Greenford has still some 

 pretentions to rural conditions but it is a duller and less inviting 

 district than the higher lands on the other side of the river and there- 

 fore has had less attention paid to it. The old-time famous Hammer- 

 smith Marshes were obliterated by houses and railways many years 

 ago. Owing to the great extension of buildings in these suburban 

 districts, the hunting-ground has greatly decreased in area during late 

 years, and the increased traffic, especially due to motor cars, has 

 rendered many of the lanes so dusty in summer that they cease to be 

 lit habitations for the Lepidoptera. Under these circuuistances any 

 great increase in the number of species recorded for this district 

 appears improbable, and it seems, therefore, now opportune to publish 

 the names of those species which do or did recently occur in any of 

 the localities mentioned. The names used are those of Staudinger and 

 Rebel's Catalogue of 1901, except where special mention is made to 

 the contrary. A date following the name of a locality denotes the last 

 year in which the species was observed in that locality. (For further 

 particulars of this district see Tninmctionx of the Citij of [jondoa 

 Kntoiiiolofiical and Xat. Hist. Soc, for the year 1906, p. 37 et se<i.) 



Siiiiaet/iis fahriiiana. — Chiswick, abundant. It may safely be said 

 to occur in all the localities, but being such a common insect it has 

 been neglected. 



Gly/j/ii/iteri/.c fitscofiriilidia. — -Chiswick, Barnes, Kew, Richmond 

 1915, and Wimbledon. This species may be seen on the wing at any 

 time during the day and especially in the late afternoon. It haunts 

 open spaces and meadows where its food plant, Luznla caiiipestris, 

 grows. The meadow in Chiswick where the moth was very abundant 

 and the larva was first discovered has been converted into a lawn, and 

 though the field rush still exists in the turf the moth is no longer seen. 

 The larva may be found in April in the stem of the rush below the 

 surface of the ground, {hhit. llecitrd, vol. xii., 1900, p. 192.) 



(jr. tliraf.onella. — -Richmond, 1907. var. dadiella, Richmond. The 

 type and the variety occur together. This species varies considerably 

 in the intensity of the pale costal markings, in size and colour of 

 the apical spot and dorsal patch, and in the presence or absence of the 

 metallic spots. Some specimens are almost unicolorous. The moth 

 flies in the sunshine and in the late afternoon in damp places about 

 Jitiiciis. Generally there are several together. I have seen them 

 ovipositing in the heads of .liincim, but the larvae I had all left the 

 rush-heads on hatching. Possibly they feed in the lower parts of the 

 stems. 



(jf. eiinitella. — -Chiswick, 1915. This seems to be a fairly constant 

 species but it varies in the presence or absence of pale marks between 

 the white lines on the costa. It delights to Hy in the sunshine over 

 the yellow flowers of the stone-crop. It sometimes comes down from 

 its hcjme on the wall tops into the gardens below. The egg is laid on 

 the leaf of Si'ilmn acre, and the larva feeds in the interior of the 

 leaves. It is not difficult to find, as the pale and shrunken leaves 

 betray its presence. In captivity the larva quits the foodplant 

 to spin its cocoon. This species probably occurs in some of the other 

 localities of the district, but from the nature of its habitat it is not 

 easily noticed. {H)U. Record, vol. xii, 1900, p. 298.)
