varying from a long, narrow-winged insect, like Fraxinata 
of Crewe, to the broader form of Egenaria, and varying much 
in the intensity of its markings from a plain dull dim colour, 
to a light ashy gray, with well-developed markings. My 
remembrance of the fine, unique specimen of Egenaria, when 
in Mr. Buxton’s collection, was not vivid enough to warrant 
me in saying his insect was a large Innotaria, but I often said 
I thought it was so; but on seeing his specimen again about 
two years ago, and comparing Cheshire Innotaria with it, all 
doubt in my mind vanished. I possess German Innotaria, 
which in no way differ from English specimens in my 
collection, either in colour, size, or markings; that is, they, 
the German specimens, differ in size, colour, and markings, 
as do our own.—C. S. Gregson; Rose Bank, Fletcher Grove,

Controlling Sex in Lepidoptera.—As bearing somewhat 
on the subject of “controlling sex by supply of food” in 
insects, it may be worth while to give the following :—During 
last summer I had a few larve of Exapate congelatella 
feeding on privet: as I was greatly occupied with other 
things they were neglected; the supply of food was very 
irregularly given, and short in quantity, yet the moths 
produced from them consisted of four males, full sized, and 
eleven females, some of these latter being much below the 
average of the species in size.—J. LZ. Fletcher ; Pitmaston 
Road, Worcester, February 2, 1874. 
Thecla Quercus with an Orange Spot.—Last autumn I 
took, with other specimens of purple hairstreaks, one female, 
which differs from all the rest, in having a wedge-shaped 
orange spot above the centre of each upper wing (on the 
upper side of the wings) ; the small end of the orange wedge 
is directed towards the tip of the wing, and the large end 
towards the base of the wing. Is this an unusual variety? It 
can hardly be a distinct species. I also took, by beating 
some oaks, two larve of S. Fagi, and from birch two larve 
which were more like D. pudibunda than any other species 
that I am acquainted with, but they were of a grayish brown 
colour (instead of a pale greenish yellow), with black incisions, 
and golden brown tufts on 5th to 8th segments, and a purple 
tuft on 12th segment. Is this a variety of D. pudibunda ?—
