spots or warts. The larva had now attained f inch in length. On the 5th 

 abdominal segment were two long ridge-like protuberances, obliquely 

 placed, one on each side, and meeting in a V-shaped connection on 

 the dorsal line, the point set forward. These were dark with a sharp 

 white line on the crest. On the 8th abdominal segment were two 

 dark spots, with white centres, one on each side of the dorsal line. In 

 the same manner were to be found two elongated white spots, edged 

 with black, on each of the other segments. There was a strongly 

 marked, raised, fleshy line below the spiracles, very waved in character, 

 and very angular in its waving on the 8rd, 4th, and 5th abdominal 

 segments, and from the points of the angles on which there passed down 

 and across the abdomen, three raised, dark, ridged bands. The spiracles 

 were black and surrounded with a fine white ring. The legs and 

 claspers were of the colour of the body, and, like that, finely dotted 

 with dark and light minute warts, all bearing tine short setae. The 

 anal flap was bordered also with a fringe of muiute bristles, but no 

 longer had the dark line along its contour. On May 21th the larvae 

 were grown to fully f of an inch in length, and, while resembling the 

 appearance they possessed on the 21st, were dili'erent in aspect, inas- 

 much as they were now lighter in colour and more declared in their 

 markings. The head was projecting and the prothoracic segment 

 formed almost a hood-like framing around it. This segment and the 

 mesothoracic were grey, the metathoracic and the 1st, 2nd, and brd of 

 the abdominal segments were sienna in colour, with the white dots on 

 each side of the dorsum developed into oblong, grey, ridge-like markings. 

 The next segment, the 4th abdominal, had a large diamond-shaped 

 grey blotch on the back, with lateral projections. The 5th abdominal 

 segment had the oblique dark ridges more pronounced and these were 

 still crested with a sharp white line. The Gth, 7th, and 8th abdominal 

 segments were sienna-coloured, with the two dark warts and bearing- 

 white centres, more in evidence on the 8th. The 9th abdominal 

 segment and anal claspers were grey. The dark dorsal stripe still 

 appeared on the segments forward to the 8rd abdominal, expanding 

 rather diamond-wise on each segment. At the 4th abdominal it became 

 lost in the grey blotch, and from there to the anal end was only 

 indicated by irregular markings. The three ridge-like bands at the 

 3rd, 4th, and 5th abdominal segments were more pronounced, and were 

 very light, especially the central one, and edged with dark brown 

 posteriorly. The underside, or ventral surface, from the Gth abdo- 

 minal to the last segment was light in colour, and bordered with a fine 

 bluish-grey line on the anterior edge of the anal claspers. On May 

 30th the larva^ were IJ inches long, and, while still bearing the same 

 characteristics in appearance, had then a grey aspect as a whole. The 

 lighter markings had spread in a sufiused manner upon the body, and 

 had gradually conquered the importance of the sienna colour until the 

 larva became a dull grey with a sienna stain on the metathoracic and 

 the first three abdominal segments, the sienna tint thus becoming- 

 secondary to the grey, a reverse of the arrangement in the earlier stage. 

 The head was more sharply bifid, and the crest of the prothoracic 

 segment inclined to form two points behind the crown of the head. 

 These points were grey in front, and each had a sienna blotch behind. On 

 the 4th and 5th abdominal segments the ridge-like markings had given 

 place to strongly built lateral projections, the largest on the 5th. The
