tity of interesting material was brought up for inspection. Mr. Alfred 
Sich contributed from Wiesbaden, Mr. L. B. Prout from Tenerifte and 
Austria, Mr. H. H. May from Switzerland, where he stated that in the 
past summer, during a six weeks’ stay, he had met with between 100 
and 110 species of butterflies; Dr. Chapman a large number of 
Erebias. He said the genus Krebia undoubtedly had its headquarters 
in Switzerland. There were but few species in Asia and America, 
and the great mass were to be found in the limited area of Switzer¬ 
land. The species of Krebia showed a parallel range of variation one 
to another, and from the difficulty in obtaining their life-history they 
offered great difficulties to specific determination. Mr. Prout asked if 
it was known what caused the greasy, smooth-scaled appearance of 
the species found at high altitudes. Dr. Chapman replied, he thought 
in a great meisure it was due to rubbing, and the bad condition of the 
specimens. Mr. May said he found that frequently there appeared no 
pabulum in places where the species were flying. Dr. Chapman re¬ 
marked that although the species like to fly round the barest rocks 
they do not breed there. 
April 15th, 1902. —Dark Hyberniau.e.— Mr. C. P. Pickett ex¬ 
hibited several examples of spring Hi/bernia<lac, including some very 
dark l\ railin'* leucophaearia, from Epping Forest. He stated that this 
year (1902) such forms had been far more frequent. 
Angerona prunaria Ekky.e.— Mr. Pickett further exhibited some 
forced lame of Aiu/emna prunaria. 
Spilosoma lubricipeda.— Mr. V. Eric Shaw, Spilt ism net Inbriri/ieila 
from Meltham, near Huddersfield. 
Spring Lepidoptera at Brentwood.— Mr. A. W. Mera, several of 
the spring Lepidoptera recently taken at Brentwood, including 
A/iochdina hispiilaria and Phii/alia /ir/laria. He said he had found the 
lame of these two species very much alike, and would wish to know 
of a distinctive character. A series of Graphiphora miniosa was also 
exhibited from Brentwood (Essex). 
Graphiphora populeti abundant.— Mr. W. J. Kaye said he had 
taken Graphiphora populeti abundantly at Surbiton, in a small circum¬ 
scribed area. Graphiphora ;/radii* had not been seen. 
Note on Graphiphora gracilis. —Mr. Fuller said he had generally 
taken Graphiphora //radii* in May, resting on grass stems. 
Appearance of Graphiphora jiunda.— Mr. E. M. Dadd found that 
for Graphiphora iniunla the sallows were too late, this insect being the 
very earliest of the Tacniocainpidae. 
Note on Pachnobia species, etc.— Dr. Chapman had noticed that 
at Hereford Pachnobia Icucoi/rapha appeared later than /’. rubricosa. 
Mr. Dadd said he had not found this the case at Selborne. He further 
gave some of his experiences in Berlin, where he said A*tero*copu* 
nubecuLo.vis was always found on alders in swampy places, and never 
on birch trunks. In point of time, insects in Berlin were fully a 
month later than in Britain. 
Development of Asphalia flavicornis pupa.-— Dr. Chapman asked 
if it was known whether A*phalia jiavicorni* was developed in the 
autumn. He remarked that Lachnei* lanestri* was developed from the 
middle of August right up to the middle of winter. 
Amokpha i’opuli x Smerinthus ocellata. — Mr. A. Bacot ex-
