THE entomologist’s RECORD. 
Eriogaster lanestris and Satur?iia carpini^' and exhibited a large number 
ofspecimens in illustration of the paper. Lord Walsingham congratulated 
Mr. Bateson on his paper, and on the intelligent care and method 
shown in his experiments, and said that he was glad to see that at 
C'ambridge there was an entomologist ready to enter this interesting field 
of investigation, and perhaps at some future day to contest the palm 
with Mr. Boulton as representing the sister University at Oxford. He 
had noticed that the larvae of S. carpini^ if left in a box with dead food, 
and probably starved, made a light-coloured cocoon; but that when the 
cocoon was made under natural conditions, on living foodplants on the 
moors, it was of a dark colour. Mr. Boulton, Brof. Meldola, Mr. 
Bateson, and others continued the discussion — H. Goss and W. W.

— Thu?'sday, November 1891. — Exhibits : — Dr. Buckell, portions of 
an ash tree, from wLich he had obtained 27 specimens of Zeuzera 
pyrina {cesculi) in 1890. The recent gale had snapped the trunk about 
7 feet from the ground. The portions shown abundantly illustrated 
the ravages made by the larvae, and the consequent weakening of the 
tree. Mr. Tutt, varieties of Noctua festiva from Warrington and Cleve- 
don ; Agrotis valligera from Sligo, and Agrotis corticea from St. Anne’s- 
on-Sea ; Coremia ferrugaia and C. uniaeniaria from Weymouth, illus- 
trating the difference in width of the central band; a dark specimen of 
JMrentia didy?nata from Liverpool ; Scopula decrepitalis from Glasgow, 
and the empty pupa skin of Apaiura iris., all belonging to members of 
the Record Exchange Club. Mr. Bellamy, a series of Himera pen 7 iaria, 
taken on lamps at Muswell Hill, one having the transverse lines very 
<lark with distinct shades. Mr. Bayne, Hydroecia micacea from Totten- 
ham, one of the specimens being var. rosea. Mr. Simes, Acosmetia 
caliginosa from the New Forest; Hepialus velleda, from Aberdeen; 
Sesia apiformis from Suffolk, and Anticlea sinuaia from Box Hill. 
Mr. Brout, a series of Hydroicia nictitans and H. paludis from the Isle 
of Wight, the latter coming from the marshes, and the former from the 
higher land. Mr. Southey, a series of Gortyna flavago from Highgate 
Woods. Mr. Battley, Goriyna flavago from Clapton, together with the 
preserved larva, pupa, and cocoon. Mr. Clark, a fine confluent spotted 
specimen of Argynnis aglaia from Bevendean ; also various species of 
dragonflies. Mr. Riches, various species of lepidoptera and dragonflies 
from India and England. Mr. Hollis, dragonflies, and specimens of 
other orders. Mr. Milton, several species of dragonflies in various 
stages. Mr. Heasler, Diplax flaviola from Clapham. Coleoptera : — 
Mr. Cripps, Cleonus nebulosus from Esher sandpits. 
Mr. Milton then read his paper on ^‘Dragonflies.” He stated that 
these insects had recently been separated from the Neuroptera, and 
placed in an order by themselves, called Odonata. They were divided 
into two families, and these again into six sub-families, which were 
chiefly separated by the structure of the eyes and wings. In the sub- 
family Libellulidce, the hind wings are larger than the front, and dilated 
at the base, upper part of clypeus or face grooved, eyes not prolonged 
backwards, abdomen short. In Corduliidce the eyes are slightly pro- 
longed backwards. Gomphidce has the eyes not contiguous, upper part 
of clypeus rather round, abdomen club-shaped in the male, and wings
