larvfe (shown by subsequent events to have been then full-fed) that 

 had been collected by him near Brighton on November 10th, and 

 made the following description as soon as they reached me. 



LAEVA. 



Length, 6 mm. In general shape tapering gradually from the middle towai"ds 

 both extremities. 



Head much narrower than the prothoracic segment, highly polished, orange- 

 ochraceous, more or less slightly marked laterally and posteriorly with blackish : 

 upper mouth-parts blackish, mixed with crimson : ocelli black, polished, distinct. 

 Pro^Aoracie se$r»2ew^ decidedly narrower than the mesothoracic, with the anterior 

 margin whitish. Prothoracic flate orange-ochraceous, the rather pointed ends of it 

 towards the spiracles being each occupied by a large and very conspicuous round 

 black spot : the plate is divided across the middle by an inconspicuous pale line, 

 along each side of which are three small black spots. General ground colour dirty 

 whitish, but greatly obscured posteriorly by dull reddish. The dorsal line is of the 

 pale ground colour, and on each side of it three lines of dull red alternate with two 

 lines of the ground colour : on the anterior segments the red lines are only repre- 

 sented by series of red spots. In the male larva the embryo testes show tlirough the 

 back of the fifth abdominal segment as a dark blotch. Anal plate highly polished, 

 blackish-brown. Warts and spiracles small, black, polished. Hairs and bristles 

 rather long and very pale, l^entral surface dirty yellowisli-white, not nearly so 

 much marked with red as the dorsal surface. Legs higlily polished, black, with 

 narrow pale rings at the joints. Prolegs dirty whitish, ringed with black. 



Some larvae have the head and plates rather darker than others, and the amount 

 of dark marking on the head varies somewhat in different individuals, but the 

 variations are comparatively trifling. 



It should be noticed that the larva of A. Vinelln is totally distinct 

 from that of anthyllidelJa, but shows some resemblance to that of 

 alhipalpella. 



When received, all the larva? had ceased feeding, and were spun 

 up for the winter in their domiciles, which were composed either of 

 one or more dead and shrivelled leaves of their food-plant, Genista 

 tinctoria, neatly fastened with silk to one another and to the stem, or 

 of two or more leaves fastened together at the edges : the leaves are 

 frequently more or less hollowed out from the sides, having evidently, 

 when fresh, afforded food to the larvfe, and the chambers, which are 

 neatly but sparingly lined with strikingly white silk, are often so very 

 small and inconspicuous that they are easily overlooked, even when 

 under one's very eyes. I imagine that in nature the larvae of this, the 

 earlier brood, pupate, as a rule, in their winter domiciles : in confine- 

 ment, however, some of them wandered about in the spring, but this 

 may have been due to the abnormal conditions, and the disturbances, 

 to which they are subjected, the unavoidable opening of their chambers 

 causing many of the owners to forsake them.
