Read before the Lancashire and Cheshire Oe a Society, on Monday, 
November rath, 
Havinc read with deep interest Messrs. Porritt’s, South’s, and 
Tugwell’s notes on the variation of this very variable species—see 
Entomologist, Aug. 1893, Xxvi, 247 (W. H. Tugwell) ; Sep. 1893, 
xxvi, 257 (R. South); Oct. 1893, xxvi, 296 (G. T. Porritt); Dec. 
+893, XXVI, 346 (R. South) ; April 1894, xxvii, 129 (W. H. Tugwell) ; 
July 1894, xxvii, 20 5 (W. H. Tugwell)—in which the varieties radiata, 
eboract, and fasciata are figured, and being very much interested 
in the /udricipeda rede ttite! I hope that the following particulars 
obtained from many sources, and after having seen most of the 
Yorkshire and Durham collections (not merely once, but often on 
two or three occasions) will tend to throw a little light on this 
Somewhat ‘ dark’ question. 
Spilosoma lubricipeda. The type is generally distributed, 
and I believe common in most localities, although like most other 
Others. Mr. Finlay, of Meldon Park, Morpeth, when looking over my 
Collection a short time ago, informed me that S. /uéricipeda is rare 
in the neighbourhood of Morpeth. 
The larvee, when full-fed and about to pupate, are not by any 
me€ans particular in the choice of their abode, such unlikely places 
as old kettles, pots and pans of all descriptions, pieces of brown 
Paper, newspaper, old rags, the stalk of a cabbage, or in the pithy 
branches of the elder; and I have heard of from twelve to sixteen 
cocoons being taken q ane one cabbage-stump, whilst as many as 
123 cocoons of 5S. /ubricifeda have been taken from a piece of 
old canvas which had been rolled up and thrust into the hedge- 
bottom. The egg, larva, pupa, and the ordinary forms of the imago 
are too well known to need any description, so I will at once 
proceed to the chief feature of this paper, viz., a description of the 
principal varieties which are known to occur. 
VaR iata. In addition to the specimen figured in Westwood 
and Humphreys British Moths, plate xviii, figure 19, 1843, which 
was taken in Yorkshire, and that figured by Newman in the 
1894.
