86 THE entomologist's kecord. 



(without the action of an abnormal outward factor) by the, in that case;. 

 patholoi/ical faihire of paheform plasm-meuiory. That aberrations- 

 do so appear is perhaps proved by the (occasional) records of extreme 

 forms, bred spontaneously, under normal conditions, among large 

 numbers of normal specimens. 



Explanation of Plate VII. 



Figs. 1-8 represent aberrations of l^anessa urticae, obtained by exposure of 

 pupaj to artificial heat (insolations) and presenting characters found perfectly 

 developed in related species (e.f/.. an ocellus in figs. 1, 2, B, 5, 6, as in I', io, see figs. 

 9, 10, 11 and 12 ; a conspicuous margin in tig. 4, as in V. antiopa : a band across 

 the wing in fig. 8 as in V. lerana ab. prorsa) Fig. 10 was bred by Standfuss after 

 two " insolations " of half an hour each. 



Notes on Microlepidoptera of Southwest London. 



By ALFRED SICH, F.E.S. 



On August 28th, 1907, I saw what at first I took for a small piece 

 of straw lying crossways on a l)irch trunk in the garden at Chiswick. 

 As I approached, the object took wing, and on capture proved to be a 

 specimen of Sitntroi/a ccrealdln, 01. This is not a common insect, and 

 the date is, 1 think, much later than usual for its appearance, but those 

 insects which are more or less connected with articles of commerce, as 

 I presume this species is, are often somewhat irregular in their times 

 of appearance. 



While searching tree-trunks, on -July 27th, 1907, on what was 

 then the Chiswick Golf Links, I found several specimens of Tinea 

 rloacella, Hw., resting on a trunk attacked by a fungoid growth. 

 Among them I noticed a rather small, very dark specimen, which was 

 taken. When preparing to set this the next morning, I was delighted 

 to find that it was a specimen of Tinea caniprinnili/eUa, H.-S. jSub- 

 sequent search revealed no further specimens. 



I took one specimen of Tinea nitiripnnctella, Hw., off a wall of an 

 out-house in Chiswick, on July 8th, 1900. This had much more the 

 habit of an < >rnix than of a Tinea. It sat up, so to speak, like an (>ntia\ 

 and also twirled its antenna\ as do members of that genus. On 

 May 22nd, 1907, T was surprised to find an example of Lit/iocnlletis 

 heerieriella, Zell., at rest on apple-bark (Chiswick); there was an oak- 

 tree in close proximity, but I had never taken this species in the 

 district previously. While mentioning this genus, it may be, perhaps, 

 well to record the occurrence of some species grouped under the old, 

 and now obsolete, name of '' ponrifoliella.'" Since Mr. E. R. Bankes 

 and Dr. Wood thoroughly investigated this group, the determination 

 of the species forming it has been made much less difficult, and all 

 microlepidopterists are greatly indebted to these two entomologists for 

 their careful elucidation of this hitherto obscure group. I have bred 

 Lithocolletis cera.ncolella, H.-S., in Chiswick, from cultivated cherry, 

 but have not yet found the mines on peach. L. spinicnlella, Zell.,
