bottom of ponds, and he had frequently found the carnivorous species 
in that situation, but the other kinds were usually embedded in the banks 
above water-line. Mr. Cripps, Laihrobiitm multipunctum from Mitcham. 
Thursday , April 2nd , 1891.—Exhibits:—Lepidoptera. Mr. Smith, 
a pair of Nyssia hispidaria from West Wickham. Mr. Battley, a series 
of Euplexia lucipara , bred from larvae taken at Stamford Hill These 
specimens varied in the intensity of the black and yellow sub-marginal 
lines, and in the width of the central band. Mr. Hodges, pale forms of 
Acidalia promutata ( marginepunctatd) from the Isle of Wight; also, for 
comparison, specimens from Portland and other localities. Mr. Prout, 
long and variable series of Bryophila glandifera, from Sandown. 
Coleoptera : — Mr. Heasler exhibited a specimen of Adtemeles 
emarginatus from Loughton. The Secretary read a paper by Mr. 
Ernest Anderson of Melbourne, entitled “A Trip to Corranwarrabool,” 
which gave a very graphic account of an entomological expedition in 
Victoria. Mr. Cripps proposed that a vote of thanks be given to Mr. 
Anderson for his paper. This was seconded by Mr. Simes, and carried. 
Thursday , April 16th , 1891.—Mr. Battley exhibited fine specimens 
of Bombyx rubi bred from larvae taken at Reigate, one of the females 
having a light circle on the right fore-wing between the two transverse 
lines. On the left hind-wing one of the rays ended abruptly in the 
centre of the wing. Messrs. Clark and Tutt exhibited long series of 
LiTHOSiiDiE, and Mr. Tutt read the following notes on parallel variation 
in certain species of the genus Lithosia :—“The genus Lithosia consists 
essentially of the following groups in their normal forms : (1) Spotted 
species as muscerda , (2) unicolorous golden species as aureola , (3) uni- 
colorous yellow-ochreous species as deplana , (4) grey species with lighter 
costa as griseola , and (5) grey species with distinct yellow costa as com- 
plana. If we simply study our well-known varieties, we notice that 
what is the typical or general form in one species, becomes varietal in 
another; thus- griseola has an unicolorous yellow variety stramineola , 
and a form in which the yellow costa is almost as distinct as in com- 
planula . Again depla?ia exhibits a bright yellow costa variety, and also 
a dark ochreous form. But pygmceola , generally considered a var. of 
lutarella , exhibits this parallel variation—or rather an attempt to follow 
the general forms of other species in its variation—in a most striking 
manner.''’ The first batch of these specimens exhibited showed an uni¬ 
colorous pale yellow form of the same shade as griseola var. stramineola , 
the second batch of the golden colour of aureola , a third set was of a 
dark grey colour with a pale costa like typical griseola , whilst another 
batch were leadenjgrey with a distinct yellow costa like complanula andcom- 
plana . In addition, an almost melanic specimen was exhibited, and Mr 
Tutt remarked that Mr. Bird had taken a specimen spotted somewhat 
like muscerda. The named varieties of Dr. Staudinger’s Catalogue were 
then noticed as also the fact that pygmceola , though really subject to a 
great range of variation in itself, was treated as a simple varietal form 
by Staudinger. Mr. Tutt drew attention to other genera where the 
tendency for varietal forms of a species, to follow other species is very 
marked, and suggested that among those Nocture which he had worked 
out, it was almost universally so. Mr. Heasler exhibited a series of 
Agathidium nigrinum from Highgate Woods.
