Not. 21st, 1899.— Papilio machaon aberrations. —Mr. Clark exhi¬ 
bited specimens of P. machaon from Wieken, taken between June 10th 
and 17th, one having an extra black spot at the apex of the forewings. 
Dr. Sequeira, also a specimen taken in 1894, of abnormal form which 
he identified with aberration natzhai, Garb., mentioned in Tutt’s 
British Butterflies under the description “ an abnormal form in which 
the outer and inner margins are strongly bent inwards, making the 
wings narrower and smaller, and forming at the anal angle a deep 
inlet of elliptical form.” 
Agrotis saucia from Sandown.— Mr. May, several A. saucia from 
Sandown, picked out of a bred series from larva 1 . One had a dark band 
on outer margin, and two were of the ab. nipricost-a. 
Papilio machaon and allied species.— Mr. Bacot, a large selection 
of P. machaon , including both captured and bred specimens, from 
Wieken and Norfolk. A series of P. hospiton was also shown, and 
this was said to be the Corsican form of machaon. A single P. 
poilalirius, bred from a continental pupa, was very pale, but this was 
said to be the usual result obtained by those who breed P. podalinus 
in captivity. 
Collection of Psychids.— Dr. T. A. Chapman, a collection of 
Psychids, including Proutia betulina, one taken in Epping Forest, 
continental forms, and one bred by Mr. Whittle, of Southend, Bacotia 
sepiitm and one which he believed to be P. salicolella from Epping 
Forest, bred by Mr. Prout, but this might prove to be a new and 
undescribed species. 
Dyschorista suspecta. — Mr. Prout, specimens of J>. susjwcta, from 
Wimbledon and Aberdeen. He mentioned that Mr. Kaye had raised 
a question as to whether this species was congeneric with I Ktissipuncta, 
as placed by Lederer. Mr. Prout also thought that the larva did not 
seem to be congeneric with that of D. fissipuncta. 
Oporabia autumnata.— Mr. Prout mentioned that misfortune had 
attended his breeding this species. A few interesting forms had 
hatched. The dates of emergence were from .July 30th-November 
14th, these being actually the offspring of the same parents, and 
having pupated at the same time. The difference of dates is wide 
enough to be interesting. Of two found feeding on pine, by Dr. 
Chapman, near Cannes, one proved to be ichneumoned and one was 
crippled, but showed itself to be a dark autumnata. 
Interference with collecting in Epping Forest. — A letter had 
been received from the Epping Forest Committee of the City Corpora¬ 
tion, stating that in answer to the representations of the Society the 
keepers will lie instructed not to interfere with entomologists in their 
pursuits, unless there is actual damage to the trees. 
Discussion on Papilio machaon. — Dr. Sequeira remarked on the 
fact that in June last all stages of the butterfly were to be obtained at 
one time, i.e., ova, young larva?, fullfed larva 1 , pupa, and imagines. 
Mr. Prout suggested that anyone able to give proofs of its being 
double-brooded, or who could show that the pupa goes over two years, 
should do so. Mr. E. M. Dadd asked “why was this insect confined 
in England to the Broads and Wieken Fen ” ? The food-plant occurs 
plentifully in marshy places in several parts of England. In Germany 
he had found the imago on liill-tops. Mr. .1. A. Clark confirmed the 
fact that in June, larva?, pupa?, and imagines could be taken at one
