P. pustulata can have no such function as the larva is an oak feeder, 
and, moreover, feeds generally high up. Careful details were given 
as to how the fragments in P. smaragdaria were affixed. It was said 
that there were special spines, which were in excess of the usual tuber¬ 
cular spines, to hold these pieces. These special tubercles and spines 
were situated on the 1st, 2nd, 3rd, and 4th abdominal segments above 
and on the bottom of the 5th and 8th. The variation of the imago 
was then considered at some length, and although it had been said there 
was very little variation Mr. Burrows had detected a great deal. The 
form prasinaria was by some considered a distinct species. The 
markings were the chief feature of the variation, colour variation 
being rare. One of the most uncommon forms was that without the 
discoidal spot. In colour, a form had been taken that was quite blue 
instead of green. Some very interesting details were given as to the 
habits of the egg-laying, larva, and perfect insect, those of the former 
being, it was believed, submitted for the first time. Mr. Clark proposed 
a hearty vote of thanks which Mr. Bacot seconded. Mr. Kaye, in 
supporting, asked if the water in the localities where P. smaragdaria 
fed was brackish enough to freeze, and also if it were known whether 
this species was subject to attacks of ichneumons. Mr. Burrows on 
rising to reply, said that in great floods the feeding-ground of P.smarag- 
tlaria was completely inundated and in severe frosts completely frozen; 
no effect seemed to be made on this insect however. He had never 
heard of an ichneumon stung specimen. 
May 1st, 1900.— Ova.— Mr. Dadd exhibited ova of Pachnobia leuco- 
graplia and of Xylocampa areola. 
Abraxas grossulariata aberrations.— Mr. Clark, some of the curious 
streaked specimens of A. grossulariata bred from Aberdeen. Mr. Bell 
also showed a melanic larva of the same species, which was completely 
black except the head. 
Acanthopsyche opacella.— Dr. Chapman, five $ Acanthopsyche 
opacella with some $ s which, it was pointed out, had six rings of woolly 
hair on the body. It was previously known that there was some wool, 
but not so placed as was now shown to be the case. 
Chesias rufata. —Dr. Chapman, some specimens of C. rufata from 
southern Europe. These were very large and of a grey banded form. 
Geometrid.e from Norway.— Mr. Prout exhibited the specimens of 
Geometridae collected in Norway by Dr. Chapman. These included 
Thera variata var. obeliscata but without variation. Emmelesia albidata, 
in which none of the specimens were so extreme as are to be found in 
Shetland. Melanippe montanata ah. fuscomarginata, Cidana abrasaria 
a long and varied series, Bupalus piniarius of the white form as 
known in Scotland, and Psychophora sabini. Some larva? were also 
shown of Meiitaea cinxia from the Isle of Wight, of bis own taking, and 
larvae of Proatia eppinyella from Chingford. 
Melalopha pigra. —Mr. Pickett, some Melaloplia piyra, one of 
which was an extremely dark and interesting form. 
Cyaniris argiolus. —Mr. Kaye said he had seen some C. argiolus at 
Worcester Park for the first time since 1888. Several members 
mentioned its having been taken very close to London, and Mr. Dadd 
said that it had been suggested that it was sometimes imported as ova 
in holly brought in at Christmas time from the country.
