120 HAUSTELLATA. — LEPIDOPTERA. 



towards the anal angle is a conspicuous, somewhat lunular, white spot, behind 

 which is a flexuous transverse white striga, reaching from the costa to the inner 

 margin; and on the hinder margin is an interrupted black line; ciHa cinereous, 

 spotted with fuscous : posterior wings fuscous ; cilia whitish-ash, with a dusky 

 line at the base : abdomen with dorsal tufts. 



Caterpillar yellow, with abroad reddish dorsal streak, and slender lateral line ;— 

 it feeds on the bramble (Rubus fruticosus) :— the imago appears towards the 

 end of June. 



This and the following insect do not well associate with the rest of the genus. 



Not common : found near Chisselliurst and Bexley woods, also at 

 Coombe and Colney-hatch.

 Similar to the last, from which it differs chiefly in the absence of the white 



blotch near the anal angle of the anterior wings, and in having the flexuous 



striga towards the hinder margin nearly obliterated. 

 Probably a suffused variety of the foregoing. 



Found with the preceding species, but very rarely.

Amidst the overpowering quantity of names which modern na- 

 turalists require in order to discriminate the numberless groups de- 

 manded by the present state of science, it is almost impossible to 

 avoid occasionally imposing a term that has been elsewhere em- 

 ployed*, of which the one applied to the present genus by Och- 



* Zerynthia, applied by Ochsenheimer in 1816 to a genus of Papilionidas and repub- 

 lished in England within this twelvemonth, has, from a useless propensity to change, been
