than their parents ; while the remaining 48-84 % were as dark as the 
$ parent, and considerably darker than the J parent, only one $ 
specimen, however, being darker than the $ parent. The second 
crossing (possibly through the action of intra-selection) had appa¬ 
rently tended to eliminate or suppress the pale (?) ancestral strain 
(determinants). In any case, the difference between the ’95 and ’96 
broods of the same race seemed worth attention. Lastly, Mr. Bacot 
exhibited 3 $ and 4 $ specimens of Ennomos quercinaria, bred in 
July, 1896, from ova given him by Dr. Buckell. One had no trace 
of suffusion, the remaining 6 all being strongly marked in this direc¬ 
tion, and one $ in particular having the whole ground-colour of 
both wings of a smoky hue, instead of the usual bright yellow. 
Living Endromis versicolor.— Mr. Garland exhibited a living female 
specimen of Endromis versicolor, which emerged from pupa Feb. 14th, 
1897; also four imagines of Zygaena lonicerae, from Enniskillen, 
1896, Plusia pulchrina, from Enniskillen, 1896, and Cucullia lychnitis, 
bred May, 1896, from Hampshire pupae of 1894. Remarkable aber¬ 
ration of Dromius 4-notatus. —Mr. Heasler exhibited a remarkable 
aberration of Dromius 4 -notatus, taken under bark at Richmond in 
Jan., 1897. The head was shorter, flatter, and broader ; the eyes 
being closer to the anterior margin of the thorax than was usual, 
owing to the short neck. The head was also strongly alutaceous 
and striated at the sides, making it appear very dull, whereas in the type 
form it is shiny, owing to the strife being obsolete and the surface 
very finely alutaceous. The thorax was depressed on the disc, and the 
central channel fine and sharply defined. The upper surface was 
very dull and rugulose with scattered transverse striae. In the type 
form the disc of the thorax was convex, with a broad central channel, 
and was very shiny. The elytra had the strife rather deeper than in 
the type form. On the underside, the head and thoracic segments 
all exhibited the coarse striation and dull appearance, so different 
from the type, but the abdominal segments were typical. In fact, the 
whole of these remarkable variations were confined to the head and 
thorax and their appendages. Perhaps the most remarkable differ¬ 
ence occurred in the femora, of which Mr. Heasler had drawn and 
exhibited a rough illustration, showing in what a marked manner 
they differed from typical femora, which were not only typical for the 
genus, but also, so far as he knew, for the whole of the British 
Geodephaga. The femora were also flattened on both the upper and 
undersides, and both surfaces were striated transversely. Mr. Heasler 
read the following notes on the species “ This species, in common 
with other members of the genus, has carnivorous habits, feeding on 
small insects, found on the trees which the Dromius frequents. It 
is a nocturnal species, hiding in crevices of the bark by day, and 
feeding during the night. It hyhernates under bark during the 
winter, in company with many other insects, which are always found 
in similar situations. Bearing in mind that the species is under 
bark quite six months of the year (Oct. to March), and also that there 
is in company with it a large number of insects which might become 
its natural food, and that nowhere else would it find food so readily 
during this time of year, it is quite possible that under these condi¬ 
tions the habits of the species might gradually become changed, so 
that the species became exclusively a sub-cortical feeder, The ten-
