COCHLIOPODID^. 171 



the incisions ; the sides, where most deeply hollowed out, have 

 a series of yellowish spots with rather shining darker centres ; 

 a yellow lateral line passes completely round the larva and is 

 extended across the third segment, which is ornamented in 

 front with a red spot followed by two shining greenish dots ; 

 projecting under sui'face of the third segment edged with red. 

 Head, pale greenish ; mouth, and a spot on each side of it, 

 dark brown ; under surface glistening, whitish, like that of a 

 slug or snail ; legs whitish. (C. Fenn.) 



August to October, on Oak, feeding on the leaves. 



Pupa short, thick, and stumpy : broadest about the middle 

 of the abdomen ; thorax large, rounded, extended in front 

 above the head; wing-cases long, well marked, with the 

 neuration plainly traceable; leg-cases almost free, those of 

 the third pair extending beyond the wing-cases to the anal 

 extremity ; creamy-white, with head and thorax tinged with 

 brown ; eyes visibly blackish ; on the dorsal surface of each 

 segment from the sixth to the twelfth is a broad transverse 

 yellowish band ; the whole surface roughened with minute 

 spines pointing backward, these spines being yellow at the 

 base, dark brown at the tip. In a broad, ovate-cylindrical 

 cocoon, which becomes flattened on each side when attached 

 to others on a leaf, and when upon an oak leaf fits so 

 closely to it as to take the impi^ession of the smallest veins ; 

 texture firm and rather hard, formed of reddish-brown silk 

 lined inside with glistening white silk, and surrounded on the 

 outside with a quantity of loose web. In this cocoon the larva 

 remains unchanged through the winter and until the middle 

 of June, the pupal stage lasting little more than a fortnight.

The eggs of this species are curiously broad and flat, almost 

 scale-like as in the Tortrices. The larva is exceedingly 

 difficult to rear in confinement. The moth frequents oak- 

 woods, and doubtless flies at night. In the daytime it is 

 rather sluggish, sitting in oak trees — young ones especially —
