the south of England, where it is perhaps most plentiful 

 in the New Forest ; it occurs at Stowmarket in Suffolk, 

 and near Worcester. 



The expansion of the wings is about 1J inch. The 

 fore-wings are of a whitish-ochreous, marked with 

 greyish-brown, there being a large blotch of the latter 

 colour near the base, and a thickish line above and 

 below the reniform stigma ; all the three stigmata are 

 conspicuously of the pale ground-colour with dark out- 

 lines ; many of the veins are also greyish-brown ; the 

 hind-wings are whitish. 



The larva is of a brownish-black, with the dorsal, 

 subdorsal, and spiracular lines of a brilliant white. It 

 feeds on oak in May. 



The perfect insect appears in July, and may be 

 occasionally met with at sugar. 



FAMILY IX. COSMIM. 

 COSMIA TRAPEZINA. THE DUN-BAK. 



A very plentiful species, and generally distributed 

 throughout the country. 



The expansion of the wings is about 1J inch. The 

 fore-wings vary a good deal in colour from greyish- 

 ochreous to reddish-ochreous, with an ill-defined 

 angulated darker band in the middle of the wing ; 

 before this is an oblique transverse dark line, edged 

 internally with white, and beyond it an angulated 

 transverse dark line, edged externally with white ; 

 these two lines are very much nearer together on the 

 inner margin than they are on the costa. 



The larva is greenish, with the dorsal, subdorsal, 

 and spiracular lines white; the spots blackish-green.
