Mr. Edelsten, was that the black form at present known in Great 
Britain as var. Hessii, is actually Nonayria dissoluta (Tr.)., ( = neurica 
Hb., 659-61, non 381 and Hessii, Bdv.), and that the species regarded 
as the British N. neurica, is var. arundineta (Schmidt), of N. dissoluta. 
March 6th, 1906.— Hemithea aestivaria, etc. —Mr. L. B. Prout ex¬ 
hibited specimens from Japan larger than the European form ; also 
Thalera fimbrialis (Scopuli), from Central France and Spain, Hemithea 
distinctaria (Walker), and H. disjuncta (Walker), from India, and an 
apparent Hemithea —species unknown—from North Queensland. 
Rev. C. R. N. Burrows exhibited H. aestivaria from Bentley, Suffolk. 
PIeliophobus hispida from Torquay. —Mr. Y. E. Shaw, a fine series 
taken at rest and on “sugar” in September, 1905. 
Paper. —Rev. C. R. N. Burrows read a paper on Hemithea aestivaria, 
the bulk of which was devoted to the larval characteristics; by dia¬ 
grams and description he showed that the larva bears, in a modified 
form, the highly specialised appendages used by P. smaratjdaria to 
attach its artificial covering, and also possesses spicules similar to those 
found on Terpne papilionaria. So far as the larva is concerned the 
species would therefore appear to form a connecting link between these 
two species. 
March 20th, 1906.— Triaena psi and T. tridens. —Dr. T. A. 
Chapman exhibited a series of supposed T. tridens, from the late 
Mrs. Bazett’s collection, which he pronounced to consist entirely of 
T. psi, also the late Mr. Barrett’s scries of T. psi and T. tridens, 
which showed some confounding of the two species. 
Messrs. Bell, Burrows, Mera, Prout, and Riches, also showed 
series of these species. 
Nonagria dissoluta and N. dissoluta var. arundineta.— Mr. 
Id. M. Edelsten exhibited these forms ex. the late Mr. Barrett’s collec¬ 
tion, in which they appeared as N. neurica, Hb. 
Paper.— Dr. T. A. Chapman read a paper on “ The Differentiation 
of Triaena tridens and T. psi,” which is included in this volume. 
April 3rd, 1906. —Donation. —Mr. W. J. Kaye presented to the 
Society’s collection specimens of Lithopliane conformis ex Erwick 
collection. 
New Member.— Mr. L. W. Newman, of Bexley, was elected. 
Melanic Lepidoptera from Richmond Park.— Mr. E. A. Cockayne 
exhibited dark forms of Erannis leucopliaearia and Apocheima hispidaria 
taken in 1906. 
Unusual Position of Anthrocera Cocoon. —Dr. G. G. C. Hodgson, 
a cocoon of Anthrocera JiMpendiilae found on a hawthorn bush about 
two feet above the ground. 
Anticlea badiata.—Extended Emergence. —Mr. W. J. Kaye, a 
series bred from ova laid by Surbiton J. The emergence extended 
from February 1st to March 22nd, although all the larvte pupated 
within two or three days. 
Ithysia lapponaria x Zonaria hybrids. —Mr. A. W. Mera, $ and 2 
specimens, the former showing more resemblance to the $ parent 
(A 7 , zonaria) than the latter. Several pairings of the hybrids were 
obtained, and the 2 s went through the action of oviposition, but no 
ova were laid.
