in hatching pup* that a bell glass was an excellent covering, as with 
slight moistening a humid atmosphere could be maintained such as 
was beneficial to emergence. Dr. Chapman referred to some of the 
scientific aspects of a pupa. He said that the lepidopterous pupa was 
descended from the nymphs of insects that had no pupal stage. The 
pupa as an intermediate stage has brought about specialisation in the 
larval form. He considered that the quiescent pupa was evolved for 
protective purposes. 
June 5th, 1900. —Lozopera francillonana.— Dr. Chapman exhi¬ 
bited some specimens of L. francillonana with its parasite Clielonus 
inanitis; also a piece of the food-plant, Ferula communis, showing the 
entry hole of the larva, prepared exit holes, utilised exit holes with 
empty pupae in situ, exits of parasites and tunnels made by the larva. 
This prepared stem showed that the larva makes its entry under the 
petiole and works its way upward and finally outward, leaving a thin 
layer of epidermis at the exit; if this be faulty the larva fills up the 
hole with silk. 
Nemeorius lucina.- —Mr. Pickett, specimens of N. lucina taken the 
previous day on the Guildford Downs, including a specimen having 
some of the spots on the hindwings almost yellow instead of the normal 
brown colour ; also Callophrys nibi, Cyaniris aryiolus, Folyommatus 
alexis, &c., from the same district, and a living specimen of Arctia 
villica bred from a Deal larva. 
Psychids.— Mr. Prout reported that he had been successful in 
beating for “ Proutias ” at Epping, chiefly from hawthorn. 
Sesia oynipiformis. —Dr. Chapman reported S. cynipifurmis in a 
wound in oak bark at Epping. 
Secretarial communications. —Mr. Bell read a telegram received 
from Dr. Sequeira advising that Mrs. Clark, the wife of one of the 
Society’s Vice-presidents, died on the 3rd inst. Mr. Prout proposed 
a vote of condolence, which was unanimously adopted. The death at 
Port Elizabeth of Mr. E. Iieasler, a member of the Society, was also 
reported. A proposal from the Chair that the Secretary should write 
to Mr. Id. Heasler expressing the Society’s sincere sympathy and 
regret was supported by all present. 
Committee report.— Mr. H. A. Fuller, on behalf of the Committee 
appointed to make arrangements for the Annual Excursion, reported 
that Barthorne Woods (near Effingham Junction) had been fixed upon 
as a locality likely to give good collecting. Full details of times of 
trains, reduction of fares, &c., were given, and June 23rd suggested as 
a favourable date. Dr. Chapman proposed, and Mr. Bell seconded, 
the adoption of the Committee’s programme, and at the Chairman’s 
suggestion Mr. H. A. Fuller was appointed leader of the expedition. 
June 19th, 1900.— Lepidoptera.— Mr. Bacot exhibited specimens 
of Anthocaris India and A. beleniia and two examples of Thais polyxena ; 
one of the last was a striking aberration, the black markings on the 
forewings varying from the type both in formation and disposition. 
Some larvae of Pachnohia leucoyrapha, a pair of Spilosoma urticae, very 
strongly marked, and ova of Centra erminea. Mr. Bacot further 
exhibited ova of S. urticae, and larvae of Axylia pntris, which he 
placed at the disposal of any members who were in want of them.
