68 LEPIDOPTERA. 



middle another, considerably indented, both rather indistinct ; 

 before the second is a faint double discal blotch of the same 

 colour ; cilia pale fulvous with a dark brown basal line. 

 Female with the antennae threadlike ; slightly larger and 

 paler, otherwise similar. Underside of all the wings bright 

 light ochreous, without markings, except that the cilia 

 of the fore wings are blackish ; body and legs ochreous- 

 brown. 



Little or no variation has been observed, in this species, 

 with us ; but it seems here to have in some degree deterio- 

 rated from the typical characters, as regards, at least, the 

 hind wings. Between the two faintly brown transverse lines 

 of these wings, and in contact with the second, there is, in 

 Continental examples, a large blotch of a delicate warm fawn 

 colour, within which are two or three small, pale yellow spots, 

 and just beyond the second line a pair of distinct, round, 

 black dots, the lower being the larger. These yellow spots and 

 black dots are nearly always obsolete in British specimens, 

 and in the very rare instances in which the latter are faintly 

 visible they are placed more closely together than in those 

 from abroad. No corresponding discrepancy appears in the 

 fore wings. 



On the wing in the middle of June, but has been met with 

 from the end of May to July. One specimen has been reared 

 in October in confinement. 



Larva one inch long, moderately slender ; head large and 

 broad, deeply cleft above, flattened in front ; pinkish, with the 

 lobes outlined and dotted with brown, and some brown spots 

 on the face ; fourth segment with an elevated dorsal process, 

 or hump, of a brown colour, divided into two blunt tubercles 

 tipped with yellow ; anal segment without prolegs, but pro- 

 duced into a long tapering point, curved a little upwards ; 

 thoracic segments yellowish-brown, blotched on the back with 

 crimson-brown ; behind the tubercles the colour of the back 

 and sides is of a brilliant deep yellow, with minute elongated
