360 HEWETT : SPILOSOMA LUBRICIPEDA AND ITS VARIETIES. 
wings, arranged as follows :—One in the centre of the costa, two near 
the tip, and two in the centre of the inner margin, the hind-wings 
being spotless. Five of the specimens were very interesting varieties 
and quite distinct from either eboraci or fasctata, being identical with 
figure 1 E on plate 76 of Barrett’s ‘ Lepidoptera,’ indeed this figure 
is drawn from a specimen formerly in the possession of Mr. Jackson. 
This variety is most certainly much rarer than any other of the 
known varieties excepting, perhaps, that extremely rare form in 
which the spots are almost, if not entirely, wanting from both 
front and hind wings; of this form Mr. Jackson possesses two 
examples. 
The only immaculate specimen I have seen or heard of is that in 
the possession of Mr. S. J. Capper, of Liverpool, and which I had the 
pleasure of viewing when looking over that gentleman’s magnificent 
collection in August 1893; probably this specimen is unique; it is 
a white female. 
Mr. Jackson has bred S. /ubricipeda from larve collected all 
round York, and not merely from one particular locality, for the past 
thirty years, and during the past twelve in great numbers, but has 
never bred radiata, nor any form very nearly approaching it. 
Mr. Robert Dutton, of York, has some twelve examples, seven 
males and five females, of variety eboraci, and one or two of the 
variety fasciata, as well as numerous intermediate forms ; these he had 
selected from a great number of specimens reared from York larve. 
In the collection of the late Mr. Robert Cook, of York (which, 
through the kindness of his widow, I recently had the pleasure of 
inspecting), there are three or four forms corresponding to the 
variety fasciata; one of them had both fore- and hind-wings 
of a uniform dark ochreous colour, the fore-wings especially so. 
There is a very similar specimen, only with not such pronounced 
markings, in the Allis collection. 
I have this year bred some 500 S. dubricipeda from larve and 
pup obtained from Hull, and from these I got some very nicely- 
marked forms, including two examples of the variety eboract, both 
females, and some half dozen fasciata; also an example (female) 
having the hind-wings similar to var. radiata, i.e., smoky black, the 
basal area, wing-rays and fringe being cream coloured; the head 
and thorax cream coloured ; body yellow, with six black spots down - 
the middle and on each side; antenne simple, fore-wings rather 
_ thickly marked. This is the variety for which I propose the name 
of semt-radiata. 1 have a very similar specimen, also a female, 
taken at rest near Driffield, but this has the fore-wings typical ; 
nearly all the forms I selected from the Hull lot have this feature»
