36 THE ENTOMOLOGIST’S RECORD. 
He also informed me that he took them in the same locality, at the 
same time. I showed them to Mr. Tugwell and he thought so little of 
them that I did not trouble to give him one, but Mr. Coverdale and 
Mr. Bower, to whom I showed them, expressed some interest, and I 
accordingly gave them each a specimen. A year or two afterwards I 
bought Coverdale’s collection before he went abroad, and so his speci- 
men came back to me. I have the four specimens now. I wrote to 
several of my correspondents about these examples, and I had a variety 
of opinions as to what they were, and where they came from, and then 
for a time I thought little of the matter, and they rested in my 
collection. They were not particularly well set (although both the 
pale and typical forms were similarly set, on our white entomological 
pins) and I gradually replaced the typical ones with better specimens 
that were set in a style L approved. As collecting slowed down and I 
began to study more, 1 was one day overhauling the drawers of the 
Geometrids at the British Museum, when I spotted the pale Phibalapteryx 
under the name of P. aquata. Iam not sufficiently well trained even 
now to see any real distinction between aquata and vitalbata, except the 
difference in the ground colour, the former being white, otherwise the 
pattern and arrangement of the markings appear identical. 
Mr. Bower spent an evening with mea little while since and, in 
the course of our gossip, he told me that shortly before the death of 
Mr. 8. Stevens he was going through the latter’s collection, when the 
latter pointed out a specimen of the pale insect labelled ‘‘ unique.”’ Mr. 
Bower told-him that he had a specimen from me and gave him some 
details, and states that he then removed the ‘‘unique”’ from the 
cabinet. 
I have since had some correspondence with Mr. Prout about the 
insect, and he informs me that there were two examples sold with the 
‘“‘ Tugwell”’ collection, one of which was bought by Dr. Sequeira, but 
that he does not know what became of the other. These must have 
been obtained by Tugwell subsequently to my having shown him my 
specimens, but the locality seems not to be known. I have no doubt 
there are other examples in various collections passed over, aS mine 
were for so many years, as pale forms of P. vitalbata. 
Mr. Prout has given me the following information of the insect : 
Aquata, Hb., ‘* Hur. Schmett.,” fig. 410, without description ; the 
figure is good, and as the species does not vary there is no need to give 
a description of the figure. Réssler and Hering indicate the larva as 
feeding on Anemone pulsatilla and A. ranunculoides, but the former says 
that in the absence of the Anemone species it can easily be reared on 
Clematis. Hering gives it as occurring in Pomerania, Speyer in 
Waldeck, Réssler in Nassau, Bremer for eastern Siberia, Staudinger 
for Amurland. The distribution from Staudinger and - Wocke’s 
Catalog, p. 192 reads ‘‘ Germany, Belgium, Holland, Lugdun., ? Pied- 
mont, ? Sarepta, Altai.”

TYPHLOPSYLLA TRISTIS, sp. nov. (fig. 1).—The spine just anterior to the 
antennal groove, in this species, is larger than in most species of the genus T’yphlop- 
sylla. Immediately in front of this spine there is a series of six short bristles, 
followed by a series of three longer ones. There is a single long bristle between
