on the matter. Why this larva, that feeds on trees, should require 
this protection of clothing the author was unable to answer, as pro¬ 
tection from flood, as in P. smaragdaria, cannot apparently be needed. 
The special processes to which the silken strands are attached were 
found to be filled with fluid, and it was discovered that if a larva was 
once stripped of its clothing, it did not again cover itself. In the 
young larva special organs were present, which are discarded for hooks 
in later stages. Very many drawings and sketches of this most 
interesting larva were handed round for inspection, showing the 
position and nature of these special organs, of which the larva makes use. 
Mr. W. L. Prout, at the close of the paper, proposed a hearty vote 
of thanks to Mr. Burrows -for his valuable paper, and asked if P. 
smaragdaria was really close to P. pustulata. Mr. Bacot seconded the 
vote, and suggested that probably upon the fact of the spiracles moving 
upwards, the ancestor was a species feeding near the sea, and that this 
character had been retained. Mr. J. W. Tutt supported the vote, and 
said he had found P. smaragdaria (a species in England always found 
on salt marshes) 5,000ft. up on the Dauphine Alps on Gnaplialium. 
He complimented Mr. Burrows on his excellent figures, and said they 
represented a great deal of original research. Dr. Chapman expressed 
his personal thanks, and said he could not but consider that P. 
pustulata and P. smaragdaria were closely related. The processes in 
the larvae were the same, and certainly suggested relationship. The 
vote of thanks was put, and carried with acclamation, and Mr. Burrows 
briefly replied. 
April 7th, 1903.— New Members.— Mr. P. Tantz, 33, North 
Audley Street, W., and Mr. H. E. Tantz, 3, Crediton Road, West 
Hampstead, N.W., were elected members of the Society, 
Special Exhibition of Triph.enas.— A special exhibition of 
Triphienas was held, towards which many members contributed 
material. Mr. J. A. Clark, a cabinet drawer containing long and 
variable series of T. subsequa (= comes) and fimbriata. A form which 
called for especial attention in the former species, was a strongly 
banded greyish variety. Mr. A. W. Mera inquired if this was known 
to be a marsh form. He had seen similar specimens that had been 
taken at Cambridge. Mr. Mera showed some exceptionally dark T. 
subsequa (= comes). Dr. Sequeira, a particularly fine, rich, chocolate- 
coloured T. fimbriata, with a peculiar gloss, and a fine form of the same 
species with almost silvery markings. Mr. C. P. Pickett, some fine 
bred T. fimbriata of large size. Mr. W. J. Kaye, a series of T. subsequa 
bred from a portion of one batch of eggs from Forres. The series con¬ 
tained all the forms between the normal and extreme T. var. curtisii. 
Rev. C. R. N. Burrows, a remarkable aberration of Triphaena pronuba, 
with long longitudinal streaks on forewing, and an extremely small 
specimen of the same species. Further, two banded T. subsequa from 
Mucking, and some remarkably dark, and even red, specimens, also 
from Mucking, Essex. Mr. 8. J. Bell, some fine T. fimbriata, with 
examples of the extreme dark green form. He remarked that he 
thought these latter were always smaller in size. Mr. T. H. Hamling, 
some T. fimbriata from Hampstead, with a large proportion of the 
chocolate form. Mr. J. Riches, T . fimbriata, also from Hampstead, of 
an exceptionally large and handsome type. Mr. A. Bacot, T. subsequa,
