Mr. Robert Adkin exhibited two series of Aflecta occulta 
from Rannoch: the one consisted of captured examples 
which varied in colour from almost black to the lghter 
shades of grey; the other of bred specimens, all of which 
were of the black form, and in this respect closely followed 
the female parent, which was one of the darkest of the 
moths captured: one of them had subdiaphanous hind 
wings. The larve from which they were reared were fed 
up on dock, and the moths appeared between 14th September 
and 3rd December last. . 
Mr. Frederick Clark exhibited in the lantern a series of 
sixty photo-micrographic slides of insect anatomy, giving 
short descriptive notes with each subject. 
A brief outline of the method employed to prepare these 
was illustrated by diagrams. 
Commencing with the antenne, those of Hybernia defolt- 
aria and H. aurantiaria were compared, followed by those of 
the gnat, vapourer moth, small tortoiseshell butterfly, and 
cockchafer. The well-known blow-fly proboscis at three 
magnifications, the higher one giving the structure of the 
pseudo-trachea very clearly. Tongues of the small white 
and tortoiseshell butterflies, the latter showing the barrel- 
shaped organs of taste. Tongue of the cricket, with one of 
high magnification, the beautiful wavy lines of this object 
being much admired. Portion of the compound eye of 
Hydrophilus piceus, showing facets and eye of the drone-fly 
in section. Wings of humble-bee placed in position to 
illustrate the method by which the fore and hind wings 
are attached by means of hooklets. Feet of blow-fly and 
dung-fly ; fore-leg of Dytiscus highly magnified, showing the 
small suckers. Feet of humble-bee with “ bread-basket.”’ 
Saws of the saw-fly, sting of bee, and a portion of tail of 
larva of May-fly, a beautiful object in which the ramifications 
of the air-tubes are most tree-like in appearance. Spiracle 
and trachee of Dytiscus. Hairs of larvee of vapourer moth and 
Dermestes. Scales of Polyommatus tcarus (alexis) with battle- 
dore forms, and portion of wing to show the mode of 
arrangement of scales in the Lepidoptera. Scale of Podura, 
the well-known test object at high magnification, the ‘‘ ex- 
clamation ”’ marks being well seen. 
Lastly, the parasite of the stickleback, one of the species 
of fresh-water fish-lice of the order Entomostraca, remark- 
able for its complex structure, being provided with an 
armament of hooklets and suckers for the purpose of 
attaching itself to its “host.” Male and female speci-
