that unless disturbed the young larvae may not leave the case 
until the spring, but it is also certain that if disturbed the 
yoLing larvae are very active, spin a lot of silk, and have no 
objection to go on feeding. Some did this from cut cases a 
month or more ago now. Mr. Tutt also exhibited a series of 
Lymna agon captured by Mr. Massey, of Didsbury, in the 
mosses in Westmoreland. They are remarkable in the male 
having two very distinct shades of colour, one set being 
of what may be termed the argus-hlue and the other of the 
ordinary agon-hlue. The females are very different from 
those of South Britain, are strongly tinged with blue, and form, 
indeed, quite a parallel aberration to the ab. argyrognomon of 
Lyccena argus. The two tints of blue traceable in the males 
are also to be distinguished in the females. He further 
exhibited a long series of ninety specimens of Hydrcecia lucensy 
captured by Mr. T. Acton in the mosses near Warrington. 
The specimens, it will be seen, are uniformly larger than the 
allied H. nictitans, and the variation is extreme, ab. grisea, ab. 
rufa, as well as some remarkably well marked ferruginous red 
type forms, being well represented, Mr. Tutt also showed for 
comparison a series of Hydrcecia paludis. These were cap- 
tured at Warrington, a few miles from the lucens locality. 
Mr. Acton remarks that although the two forms liicens and 
paludis have almost identical parallel forms of variation, yet 
they never overlap nor could one be mistaken for the other. 
The ab. intermedia {Brit. Noct., I., p. 64) and ab. grisea 
(ibid.) are remarkably well illustrated. The redder forms were 
quite new to him in paludis. He also exhibited Dyschoi-ista 
suspecta taken near Warrington, and remarked that they 
showed a wide range of variation. The brown type form 
appears to be almost unrepresented in this district, most of 
the forms ranging near ab. congener , ab. rufay and ab. 
nigrescens. The almost unicolorous forms are much more 
abundant than the variegated. He also exhibited specimens 
of Celana Haworthii from Warrington. These showed a 
perfect dichroism, some specimens being red and others 
purple in tint, exhibiting also very considerable variation in 
the number of the pale transverse lines, and also in the shape, 
size, and general characters of the stigmata.
