PSYCHIDES IN 1900. 145 



and have only to grow at each successive moult to replace the limb of 

 full size. Had the amputation taken place at the first instar this 

 would probably have occurred. When Ave come to the imago we find 

 that the limb is complete, and has grown by aid of the two intervening 

 moults to a size, though obviously not very much, still less than the 

 other. We may reach several conclusions from this specimen. 

 (1) There is a regenerative centre at the base of the leg, that can 

 renew the larval as well as the imaginal leg. (2) It cannot be the 

 source of each new larval leg at each moult, or it Avould have given 

 rise to a full-sized leg, instead of a mere sketch of one. (3) It is 

 nevertheless sufficiently large for a full-sized imaginal leg to have 

 resulted, if the imaginal leg arose entirely from the basal germinal 

 plasm. Observe that not only the tarsus is smaller than that on the 

 right side, but also both the femur and tibia. 



{To be concluded. 



Psy chides in 1900. 



By L. B. PROUT, F.E.S. 



I cannot hope that a few scrappy notes of a beginner in the study 

 of this interesting group will be of any value to those entomologists 

 who have had many years' experience of them ; but as it is quite 

 probable that there are some who, like myself, have been drawn to 

 them by the recent work which has been done by Dr. Chapman and 

 Mr. Tutt, I think I may be interesting a few at least by putting on 

 record my observations so far as they have gone. They certainly 

 illustrate once again how easily one overlooks what one does not look 

 for, for I never saw a Soltnwbia or Lujfia in situ until this season ; and 

 it seems very probable that if our collectors will only set themselves to 

 search for them, Ave shall soon add enormously to our knoAvledge of 

 their distribution; at any rate, I haA^e had no cause to complain of the 

 results of my first endeavours in this direction. 



A brief A'isit to SandoAvn, from April 9th-21st, did not Avitness much 

 serious collecting, but it afforded a good many opportunities for trunk- 

 searching. So far as I knoAv, nothing has yet been recorded as to the 

 Psychids of the district — A. G. More's list, in Venables' Guide, does 

 not include a single species ; I Avill, therefore, giA'e a list of all localities 

 AA'here I found them, though unfortunately the more difficult species 

 are not yet named. 



Taleporia tubulosa, Eetz. {pHeadohumhijcella, Hb.). A fcAV cases in 

 Centurion's Copse, near Brading, and one in BordAA^ood. I also took it 

 a feAV years ago in Alverstone Lynch. 



Lnffia, ?sp. Very common in Centurion's Copse, also in YoungAvood 

 Copse, AWerstone ; SAvarmed on some oak trees on a hill-side near 

 Alverstone, I took 60 off one tree, and left a large number behind, and 

 I noticed that seA'eral of the other trees Avere just as densely populated. 

 I take the examples from all these localities to be the same species, but 

 of course I may be mistaken. I also took tAvo apparently belonging to 

 the same species in EoAvdoAvn Copse, Brading Doaa^u, but it must have 

 been singularly scarce there. I Avorked 100 out of the 150 or so Avell- 

 groAvn trees AA^hich the copse contains, as I Avas hoping to find Diplodoma 

 herininata, of which I took a single case there in 1899 ; my quest Avas, 

 hoAvever, quite fruitless, so far as that species was concerned. The
