THE BARRED HOOK-TIP. 131; 



Central Europe to Livonia, Southern Sweden, and to Northern 

 Italy. On the Continent the caterpillar feeds on the foliage of 

 other trees than lime, and there are two broods in the year. 



The Oak Hook-tip (^Drepana bi?taria). 



The male is of an ochreous-tinged brown coloration ; all the 

 wings are crossed by two slender deep ochreous lines, and have 

 two obliquely set, almost central, black dots ; outer margin of fore 

 wings often blackish, marked towards the tip ; the hind wings 

 are deep ochreous on the front marginal area. Fore wings of 

 the female paler, and the hind wings ochreous yellow ; the cross 

 lines on the latter often lost in the ground colour (Plate 71). 



In freshly emerged male specimens the brown is sometimes 

 purplish tinged, and in some examples of the same sex the hind 

 wings may be described as ochreous, with brown bands. The 

 female occasionally has the fore wings tinged with greyish, and 

 the hind wings are sometimes banded with brown, especially on 

 the inner marginal area. 



The caterpillar is ochreous brown with a double-pointed hump 

 on ring three, a yellowish diamond on the back of rings five to ten ; 

 the front and hind rings are brown, more or less tinged with 

 purple ; yellowish lines, shaded below with purplish brown, on 

 the sides meet on the back and form an edging to the diamond 

 mark. The figure on Plate 70 shows the caterpillar in its usual 

 resting attitude. It feeds on oak. 



A widely distributed species in the southern half of England, 

 but not especially abundant in any locality, and not known to 

 occur north of Lincoln.
