HEWETT : SPILOSOMA LUBRICIPEDA AND ITS VARIETIES. 359 
county, as it occurs to my knowledge at Driffield, Darlington, Hull, 
and also in peiaees ty according to Mr. W. H. B. Fletcher's 
remarks already quo 
Mr. Carrington send (Entomologist, xxiii, page 207) ‘that 
_ S. lubricipeda variety radiata (meaning by radiata the variety eboract, 
which, until the introduction of Mr. Harrison’s form, was erroneously 
called radiata) only occurred in a timber-yard close to the railway 
Station, between the years 1860 and 1870,’ may have been correct at 
that time (although from the evidence I have obtained of its present 
distribution, I very much doubt it), but it certainly would not hold 
good at the present time, as the variety eboraci or York form is, and 
may be, bred from larve collected in any parts of the city or out- 
skirts, but is most certainly not so common as one would infer from 
Mr. Porritt’s notes on ‘the radiated varieties of the genus Arctia,’ 
where that gentleman states that the variety radia¢a (meaning the 
variety eboraci) is not at all uncommon about York. 
From some 150 S. /ubricipeda bred this season from York larve, 
I only got three specimens of the variety ebvrac?, two males and one 
female; in addition to these some 20 intermediate varieties. oF orms 
uncommon occurrence, when the species is bred in considerable 
numbers; these forms also occur fairly commonly at Hull and 
Driffield. 
I recently inspected the grand lot of varieties of S. dubricipeda 
bred by and now in the possession of Mr. George Jackson, York, his 
‘small series’ consisting of 15 rows, each row having from 20 to 22 
specimens, or 315 examples in all, of which about 50 were true 
eboraci as figured by Mr. Tugwell, Entomologist, July 1894. The 
remainder were principally varieties very closely resembling eboract 
and connecting that form with the type. The whole of these fine 
forms had been selected by Mr. Jackson from many thousands of 
S. lubricipeda which he had bred during the last few years. 
Var. fasciata (Tugwell). Mr. Jackson had numerous examples, 
both male and female, of this form, and several very nearly 
approaching it. This variety also occurs not uncommonly at 
Scarborough, Hull, Darlington, and Driffield. Some half-dozen 
' examples had the hind-wings marked very much like those of the 
variety radiata, the fore-wings not so strongly marked as in edoracz. 
For this variety, which is recurrent, and of which I have two in my 
collection from Hull and Driffield respectively, and which also occurs 
at Darlington, I would propose the varietal name of ‘ semi-radiata.’ 
Another uncommon variety has five small dots on each of the fore- 
Dec, 1894.
