NOTES ON THE BREEDING OF AMPHIDASYS STRATARIA. 95 



two white dotted wai'ts oa the 8th abdominal were now elongated, 

 raised ridges, arc-shaped, dark behind and light grey on the crest. The 

 claspers and legs were of the body colour, and the entire creature very 

 minutely dotted with light spots, here and there of a larger size. The 

 light spiracles were distinct and oval in shape, standing on end with a 

 black ring round them. The edge of the anal flap was fleshy and still 

 had hairy projections upon it. These were to be found sparsely 

 scattered all over the larva, particularly upon the head. The ridge- 

 like formations upon the abdomen at the 3rd, 4th, and .5th segments 

 of that region consisted now of broken and irregular wart-like ex- 

 cresences, and were yellowish in colour, spotted darkly here and there. 

 The dorsal stripe had faded and become absorbed by the surrounding 

 coloration, but could still be traced through the lens, forming a 

 darkish diamond-shaped lozenge on the skinfold at the rear of the 

 segments forward, and behind the grey blotch on the 4th abdominal, 

 it showed faintly in the same manner on the centre of the seg- 

 ments. On June 1st the larvfe were H inches in length, and of a 

 grey colour, exactly representing the bark of the oak. The head was 

 large, notched on the crown, and sienna-brown in colour. From the 

 crown to the mouth the front was a flat oval in form, and a tall tri- 

 angular facet bent backward on each side. A light bar crossed the 

 base of the face above the mouth. On the prothoracic segment were 

 two sienna blotches, one behind each lobe of the head, and divided 

 from it by a deep wrinkle with a light edge to it. On the metathoracic 

 and the first four abdominal segments were diamond-shaped markings 

 on the back, formed by minute dark brown warts, and, on the side of 

 each segment at the lateral points of these diamond-shaped markings, 

 there was a sienna blotch, at the base of which, and on the line of which, 

 were the light oval spiracles standing on end and enclosed with a dark 

 ring around them. On the 4th and 5th abdominal segments were 

 the strongly marked projections of lateral warts, elongated in form 

 and sienna in colour. Those on the latter segment were large and 

 fleshy in character, projecting boldly from the body. On the dorsal 

 area of the 8th abdominal segment were two warts also sienna in 

 colour, and below them, on each side, a lateral and elongated wart of 

 the same tint. The anal end and claspers were dull sienna in colour, 

 the claspers very widely spread when clinging to a flat surface, and 

 showing between those of the anal end, below the anal flap, three light 

 fleshy projecting points. The body was strongly wrinkled transversely, 

 the legs were sienna in colour, like the head and anal claspers, showing 

 a dark division between the thoracic segments when they were 

 extended. The claspers on the Gth abdominal segment were grey. The 

 three raised rings on the abdomen at the 3rd, 4th, and 5th segments 

 of that portion were sienna-coloured at the sides and lighter under- 

 neath. That part of the ventral surface between the claspers was a 

 light olive-grey in colour, finishing with a fine whitish-blue line 

 against the anal pair. The larva had short projecting sette sprinkled 

 irregularly about it, with a profuse supply upon the head and anal end. 

 It was now very lethargic in its habit, and presented a strong contrast 

 to its lively movements in the earlier stages of existence. The striking- 

 resemblance that it bore at this period to a second year's twig on oak 

 was most noticeable. The projections from the sienna-coloured mark- 

 ings on the dull grey body could not more exactly correspond wilii the
