black, with a sharp black line of definition behind the head on the 

 prothoracic segment. Two fine dorsal lines of grey-green dotted 

 markings, close together, along the back, and two broken subdorsal 

 lines of light warts on each side, of the same tint. Body covered with 

 greenish-grey warts, all emitUng a black bristle. Spiracles dark and 

 inconspicuous. Each segment sharply incised with a double transverse 

 skinfold. Legs and claspers of the colour of the body, except the 

 outer surface of the anal claspers, which, with the anal flap, were dull 

 brown in colour. The length of the larva was now ^ inch. 



By May 16th the larvfe had assumed an approach, both in form 

 and colour, to the appearance of the adult stage. The head was large 

 and boldly shaped, constructed of two lobe-like forms sharply indented 

 at the crown by the fleshy ridged point on the centre of the prothoracic 

 segment. It was sprinkled with dark warts, with whitish set^e, and 

 was dull chestnut in colour. The colour of the body was a compound 

 of dull chestnut-brown and blackish blotch-like markings, with a sharp 

 black line marking the edge of the prothoracic segment round the 

 head. The thoracic segments were blackish merging into brown 

 blotches on the 1st, 2nd, and 3rd of the abdominal segments. The 

 4th, 5th, 6th, and 7th abdominal segments were darker, and strongly 

 accentuated at the segmental skinfolds with blackish bands. The Sth 

 and 9th abdominal segments, with the anal flap and claspers, were 

 dull chestnut-brown. A sharp dark edge ran round the anal flap 

 bristling with short dark setag. These blotchy colorations of the 

 body were, more or less, distinctly marked in individual examples, but 

 were to be traced in some degree, by careful examination, in all. 

 Behind the head on the prothoracic segment were two distinct dull 

 chestnut-brown spots, one on each side of the dorsal line, and below 

 them two groups of small whitish warts. There was a dark dorsal 

 line from the crown of the prothoracic segment to the anal flap, 

 getting more broken in character as it approached the anal segment, 

 towards which it was maintained only by isolated lozenge-shaped and 

 elongated markings. On either side of the dorsal line appeared a 

 subdorsal line of whitish, elongated, warty spots, and below this, on 

 either side, three waved and broken supraspiracular lines of similar 

 spots, and again another line of the same character embracing the 

 spiracles themselves. The spiracles were light, Avith dark centres, and 

 could scarcely be distinguished from the spots before mentioned. The 

 darker parts of the body were sprinkled with dark short setse, growing from 

 the light warty spots, and the lighter portions of the larva, the head 

 and anal flap, were dotted with dark warts with light bristles. The 

 legs were light, dark spotted, with black terminations. The claspers 

 were dark, with light terminations. The size of the larvae was now ^ 

 inch in length. On May 21st the general appearance of the larva; was 

 sienna-brown in colour, finely dotted all over with minute pale warts. 

 The head was notched bluntly on the crown, forming two lobe-shaped 

 lunules of a brighter sienna colour than the body. Below these lobes, 

 across the upper part of the face, ran a light line, and beneath this a 

 broad brown band above a light triangular blotch. There was a 

 distinct dorsal stripe on the back, of a dark brown colour, accentuated 

 on each segment, and starting from a dark spot between two white 

 spots on the projecting edge of the prothoracic segment. This dorsal 

 line was finely bordered, on both sides, by a thin light line of minute
