BRITISH MOTHS. 



median black band, and a broad hind-marginal 

 black band : the head and thorax are marbled 

 with the colours of the fore wings, the body is 

 uniformly gray-brown. 



The CATERPILLAR rests in a nearly straight 

 position on the branches of the oaks, on the 

 leaves of which it feeds, the ventral surface 

 being appressed to the bark ; the head is some- 

 what narrower than the second segment, but 

 distinctly exserted ; the face is flat and the 

 crown gibbose and notched : the body is convex 

 dorsally, and flattened ventrally; the ninth 

 segment has a transverse dorsal ridge, the 

 twelfth segment has also a ridge, but this 

 terminates at each extremity in a lateral 

 tubercle surmounted by a bristle ; the fifth, 

 sixth, seventh, eighth, tenth, and eleventh 

 segments have each two wart-like tubercles 



O 



Traced transversely, each bearing a bristle ; 

 the claspers are long, dilated and divided at 

 the extremity : the colour of the head is 

 wainscot-brown, reticulated with darker 



brown, and having a conspicuous black band 

 surrounding the face, except towards the 

 mouth ; within this, and very near the crown, 

 are two eye-like black spots : the dorsal sur- 

 face of the body is dull brown, reticulated 

 with pale wainscot-brown ; the tubercles, as 

 well as certain minor warts, are rufous-brown, 

 and very glabrous ; there is a pale transverse 

 dorsal -nark on the fifth segment ; the ventral 

 surface is Whitish, inclining to glaucous, with 

 a rufou i^tch between each pair of ventral 

 claspprss. It is lull-fed about the eighth of 

 June, when it spins a thin web among the 

 oak-leaves, without descending to the ground. 

 The MOTH appears on the wing in July, and 

 has been found in Dorsetshire, Hampshire, 

 Sussex. Surrey, Kent, and Essex. I have seen 

 it, but i. L , obtained it, sitting on the trunks 

 of oaks in )arenth Wood, but the New Forest 

 in Hampshire is its most abundant locality. 

 (The scientific name is Catocala sponsa.)
