LARENTID.-E—OPORABIA. 379 



Mr. C. W. Watts, has the ground colour exquisitely silvery 

 white, with the stripes of a delicate grey but sharpened by 

 short black lines on the nervures. This appears to agree well 

 with the form called Kutnmnarid by (iiience; but that name 

 has with us been commonly associated with another peculiar 

 form, of rather large size, in wliich the fore wings are a little 

 more pointed .at the apex, though not narrowed, and the 

 texture appears rather more glossy, but the colour and mai-k- 

 ings are normal, or in the north darkened, yet which furnishes 

 no tangible character whereby it can be distinguished from 

 that now under consideration. Tiie range of this variety is 

 northern and western, and some of the most distinct looking 

 specimens have been sent to me by Mr. Adam Elliott from 

 near Jedburgh, and from Armagh by the Rev. W. F. Johnson; 

 but I have even taken this form at Norwich, and have found it 

 mixed with typical specimens from various places. Another 

 form even more remarkable has been taken in the north ; this 

 is hardly larger than Clui'undtolnd hnnnata, the fore wings 

 more triangular, and the colour mottled dark grey-brown ; 

 and is, apparently, the form which w-as caWttd n p proxi mi ir la by 

 Weaver. Of this Mr. Kenneth J. Morton took three indi- 

 viduals y///^«// hji (laij in a deep glen in a wood at Clegliorn, 

 Argyleshire ; Mr. F. N. Fierce possesses .another ; but of the 

 history and localities of this form but little is known. With 

 regard to the variety called antuinnin-'ux, it will be necessary 

 to say more under the next species. 



On the wing in October and Novemljer; but in the north 

 said to emerge as early as September or even end of August. 



L.VKVA stout, velvety ; divisions of segments well marked ; 

 head rather small, rounded, not highly polished, pale green ; 

 body bright velvety apple-green with the segmental divisions 

 yellow ; spiracles orange ; spiracular stripe yellow, undersur- 

 face conspicuously bluish-white ; legs pale green. 



Or — As above, but the divisions of the segments broadly 

 banded with ferruginous, and having a ferruginous dorsal line.
