Remarks on Spilote grossulariata. —Mr. Mera said he had bred 
about 80 imagines of Spilote grossulanata from ova laid by a dark $ 
specimen, but none closely resembled the parent, those that varied 
resembling the usual local form. Mr. J. A. Clark remarked that he 
had found that while larvae of dark forms hibernated easily, those 
bred from light parents nearly all failed in this stage. Mr. Mera 
mentioned that he had noticed when breeding both forms that the pale 
varieties were much more subject to crippling than the dark ones. 
Mr. Prout suggested that these facts seemed to support the theory that 
coloration largely depended on the excess or deficiency of vital energy 
in the individual. 
July 16th, 1901.— Scandinavian lepidoptera. —Mr. E. M. Dadd 
exhibited some Scandinavian lepidoptera, including Argynnis pales, A. 
inn, A. laodice, Lycaena amandus and L. optilete ; also from Berlin 
some Mamestra splendens. 
Angf.rona prunaria bred. —Mr. C. P. Pickett, a very variable series 
of bred Amjerona prunaria. 
Malacosoma castrensis plentiful. —Mr. Bacot reported that he 
had found larvae of Malacosoma castrensis plentiful in the Medway 
marshes. Fed in confinement they ate raspberry, willow, sallow, and 
knotgrass, preference being shown for the latter. On the same date 
(June 80th), a batch of ova of M. castrensis were also found, and just 
about the time that the larvae were spinning up, these ova produced 
ichneumons. Mr. Bacot pointed out that they would thus be ready to 
attack tbe ova of the next brood of M. castrensis, and were presumably 
confined to this species. 
Scandinavian collecting. —Mr. E. M. Dadd intimated that during 
three days collecting in Scandinavia he had seen 55 species of butter¬ 
flies. Sugaring in that region had to be done in daylight, no lamp 
being necessary. Only common Leucaniids and Agrotids were seen, 
and a very dark form of Mamestra dissimilis ( suasa ). 
Lepidoptera at Oxshott. —Mr. C. P. Pickett said he had found 
Plebeins aegon fully out at Oxshott on July 9th, and had taken Hecatera 
serena, Anarta myrtilli, and Pachycnemia hippocastanaria on the same 
occasion. 
Catocala promissa in the New Forest. —Dr. J. S. Sequeira 
recorded the capture of Catocala promissa in the New Forest on July 
3rd, 1901. 
Aug. 20th, 1901.— Variable Paciiys betularia. — Mr. J. Riches 
exhibited a bred series of Pachys betularia, varying from normal to 
fairly dark forms. The male parent, which was exhibited, was dark, 
the female (not shown) was of the ordinary form. 
Aberrations of Polyommatus corydon and P. thetis at Dover. — 
Mr. C. P. Pickett, a large number of Polyommatus corydon taken during 
the month of August at Dover, showing an extraordinary number and 
variety of aberrations. He explained this by saying that on the occa¬ 
sion of his several visits to Dover he had examined perhaps as many 
as 10,000 specimens, selecting therefrom the exceptional examples. 
Of females there were three dwarfs, one being almost as small as 
('a pi tin minima, two were perfectly blue, two were splashed with blue, 
and one asymmetrically splashed, the upper left wing only showing
