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 we 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 seyeral 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 would have given 
rise to a full-sized leg, instead of a mere sketch of one. (8) 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. 
Psychides 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 haye 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, | 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 Solenobia or Luffia in situ until this season ; and 
it seems very probable that if our collectors will only set themselves to 
search for them, we shall soon add enormously to our knowledge of 
their distribution; at any rate, I have had no cause to complain of the 
results of my first endeavours in this direction. 
A brief visit to Sandown, from April 9th-21st, did not witness much 
serious collecting, but it afforded a good many opportunities for trunk- 
searching. So far as I know, 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 will, therefore, give a list of all localities 
where I found them, though unfortunately the more difficult species 
are not yet named. 
Taleporia tubulosa, Retz. (pseudobombycella, Hb.). A few cases in 
Centurion’s Copse, near Brading, and one in Bordwood. I also took it 
a few years ago in Alyerstone Lynch. 
Luffia, ?sp. Very common in Centurion’s Copse, also in Youngwood 
Copse, Alverstone; swarmed 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 several of the other trees were 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 two apparently belonging to 
the same species in Rowdown Copse, Brading Down, but it must have 
been singularly scarce there. I worked 100 out of the 150 or so well- 
erown trees which the copse contains, as I was hoping to find Diplodoima 
herminata, of which I took a single case there in 1899 ; my quest was, 
however, quite fruitless, so far as that species was concerned. The
