appear to have been recorded as occurring in Scotland

The perfect insect appears in June, and frequents open 

 places, in woods, and the borders of thickets. 



FAMILY VIII. ACIDALID.E. 

 ACIDALIA EUSTICATA. THE LEAST CAEPET. 



This neatly marked little insect does not appear very 

 generally distributed ; it has occurred in the Isle of Port- 

 land, and near Gravesend, and in various localities 

 round London ; I have myself taken it at Lewisham. 



The expansion of the wings is rather under f inch. 

 The fore-wings are whitish, with a greyish -brown blotch 

 at the base of the costa, and broad greyish-brown central 

 bands, in which is the black central spot ; beyond this 

 is a faint grey band, rather interrupted ; the hind-wings 

 have similar markings, but not so distinct, only they 

 have no basal blotch. 



The larva is dingy brown, with paler dorsal and sub- 

 dorsal lines, and with a row of acorn-shaped pale spots on 

 the back of the fifth to ninth segments ; skin remarkably 

 rough, clothed with clubbed bristles. It feeds on lilac, 

 ivy, bramble, hawthorn, in the autumn and spring, being- 

 full fed about the end of May. 



The perfect insect appears in July, and is sometimes 

 noticed sitting in the leaves of plants ; the contrast of 

 colours rendering it rather conspicuous.
