PH 1 -CITin.E—A CROBA SIS. y 



central transverse cloud, in which are two black discal dots ; 

 second line rather inconspicuous, reddish-white, elbowed 

 inwards near both costal and dorsal margins, broadly and 

 rather smoothly bowed between, inwardly bordered by a smoky 

 cloud, outwardly by a rich red stripe; beyond this the hind 

 margin is shining smoky-grey, with a double black marginal 

 line ; cilia smoky grey. Hind wings ample, rounded behind, 

 shining smoky-brown with the nervures darker ; cilia a little 

 paler and very glossy. Female similar, with threadlike 

 antennas. 



Underside of the fore wings shining dark smoke-colour ; 

 costa dull yellow with a black sf)ot beyond the middle. 

 Hind wings pale smoke-colour. Body glistening whitish- 

 brown. 



On the wing in July and August. 



Larva spindle-shaped, naked, purple, with numerous dotted 

 white longitudinal lines, and a broad, light brown, white- 

 marbled spiracular stripe ; head and dorsal plate glossy nut- 

 brown, marbled with black. (Zincken.) 



May and June on oak ; feeding in a drawn-together mass 

 of leaves at the end of a branch, living in a tubular web, 

 joining the leaves roughly together, and gnawing their 

 surfaces. 



Pupa apparently undescribed. Zincken says that it pupates 

 in the earth. 



The moth hides during the day among the densely growing 

 masses of leaves on large oak bushes and the branches of 

 oak trees, and may be dislodged by the beating-stick, and 

 captured if the day is warm enough to induce it to fly. At 

 night it is strongly attracted by gas lamps, and will also 

 come to the sugar prepared for Nodum, yet is very restless 

 and apt to 'Aj ofl'. Its brilliant and beautiful colouring has 

 a rich appearance under the lantern light, and its hasty dis- 

 appearance is by no means gratifying to the unfortunate
