472 BRITSIH LEPIDOPTEEA. 



6th segment (2nd abdominal), very pale, and which seemed to die away 

 in a few days. After the third moult two conspicuous red spots appeared 

 on the 2nd segment ; the long white fringe hanging over and along each 

 side, together with four large black spots on the ventral surface, very 

 clearly defined ; the venter quite flat. Before its last moult the larva is 

 usually of a delicate violet or dove-grey tint, with two, orange, subdorsal 

 stripes, and has a very different appearance from any forms of the adult 

 larvae. Buckler says : The full-fed larva is about If inches in length. 

 The head is full and rounded, but smaller than the prothorax, 

 bluish-grey in colour, freckled with reddish- and brownish -grey. 

 The prothorax is margined with bluish-grey anteriorly, followed 

 by a fusiform mark of brown divided dor sally by a pale line. On the 

 back of the other segments is a series of dark grey blotches, bearing 

 the form of inverted urns. These blotches are freckled with blackish 

 atoms, the hinder portions being the darkest. Through these a darker 

 dorsal line runs, and within them, on each side of the dorsal line, are 

 two acute angular marks, of a bright ochreous-orange colour extending 

 transversely. Laterally, there are dark grey curves, on a whitish 

 ground, on the lower part of each segment, above which is a large, 

 ochreous-orange blotch, freckled with dark grey, and surrounded above 

 with a dark-grey blotch in front, and a larger blotch behind, of 

 squarish form and finely freckled with black. The dorsal marks on 

 the meso- and metathorax are blackish and rather conspicuously 

 relieved by a whitish marginal side blotch, only faintly indicated on 

 the other segments. On the meso- and metathorax also are oblique, 

 dark grey, lateral streaks, running downwards and forwards. On the 

 2nd and 3rd abdominal segments, the dark dorsal blotches are relieved 

 on either side by conspicuous whitish blotches. The ventral surface 

 is buff-yellow, and there is a central black spot on the middle of each 

 segment. On each side of the front of the prothorax, is a round wart- 

 like tubercle. The head, as well as the dorsal and lateral areas, is 

 covered with a fine pubescence, the sides being fringed below with longer 

 grey and dark brown hairs. The ventral surface is only slightly 

 pubescent. Fenn describes the larva as having the head rounded and 

 flattened, hairy ; the body elongate, flattened beneath, back and sides 

 transversely wrinkled ; sides puckered, with a fringe of rather long hairs 

 pointing downwards above the legs ; umber-brown ; dorsal spots 

 ochreous shaded with black atoms ; sides also shaded in a similar 

 manner round the pale lateral spots ; an inconspicuous row of orange 

 subdorsal spots, the 2nd segment with a red transverse band containing 

 a yellowish spot ; the lateral hairs whitish or pale grey ; the venter 

 orange-tawny with a series of prominent black spots connected by a 

 grey line, these spots very large and prominent between the prolegs ; 

 legs yellowish-brown. Borkhausen observes that the larva agrees 

 somewhat in its build with that of E. qucrcifolia, being flattened 

 ventrally and arched dorsally. It is entirely covered with fine short 

 hairs, with longer hairs laterally ; its colour ash-grey, sometimes 

 nearly blackish, at other times quite inclined to whitish ; on the dorsum 

 it is marked with large, connected, black spots, in which, on each 

 segment, are four yellowish knobs, standing in a square. The head 

 small in proportion to the size of the larva. The flat venter is whitish- 

 yellow with round cinnamon-brown spots. Crewe says that the larva 

 may be at once recognised by its orange belly.
