emit one or two hairs. Head hirsute, white marked with broad black longitudinal 

 streaks, and a spot on the lower part of each cheek and in the middle of the 

 forehead. Ventral area and about the claspers whitish. True legs and anal 

 claspers tipped with black ; abdominal claspers marked with three round spots 

 placed in tlie form of a triangle, two at the base and one near the tip of the clasper. 

 Second Moult. — Spines black aud branched, largest on the 4th, 5th, and 12th 

 segments, very miuute on the 2ad segment. A subdorsal and a lateral row of 

 orange coloured spots (varying from light orange to deejj reddish-orange) divide a 

 series of broad velvety-black bands — on the back — into three brick-shaped spots, of 

 which the medio-dorsal ones are the largest and best defined — and on the sides — 

 into oblique semi-comma shaped markings. Ou the 2nd, 3rd, and 4th segments 

 the bands are not divided, but include the orange spots along the front edge, and 

 on the 13th segment the medio-dorsal spot is the smallest and is rounded. On the 

 anal flaps are two round spots at the base and three short lines, one on each side, 

 and one at the tip, marking its margin. The division between the segments, dull 

 coloured black, showing broadly on the back, but narrowly on the sides, the 

 markings extending to just above the natural inflation. Frontal margin of the 2nd 

 segment square cut and tubercled at the angles, colouring yellow. Head and 

 forehead yellow, with a medial black spot. Two broadish black, concave longitudinal 

 streaks converging to a fine point on the top of the head, and a similai^ly convex 

 streak at tlie back of the cheek, with an ovate spot between, low down, leaving an 

 inverted V-shaped marking of the ground-colour. Lateral inflations well defined, 

 marked with round spots thus : — above the true legs two spots one above the other,- 

 on the 5th and 6th segment one spot, above the claspers two spots far apart placed 

 horizontally, on the 11th and 12th segment variable — sometimes absent. True legs 

 with a round spot at the base, and tipped with black ; abdominal claspers with a 

 round spot near the tips ; anal claspers margined with black. Under-surface of the 

 body whitish. Third Moidt. — Larva destitute of spines ; markings exactly similar to 

 those in the second moult, but the general coloration a beautiful pale blue-green — 

 almost an emerald green, and the black markings much broader. Tentacles under 

 the 2nd segment jjale orange-yellow, emitting a strong orange scent when protruded. 

 The breadth of the black markings vary greatly in individuals, some are almost 

 entirely green, others pale, others again, almost entirely yellow. The bands in 

 some examples are almost entire, and include the rows of orange spots, which latter 

 also vary from deep orange to pale yellow. In fact, the whole of the markings as 

 well as the general colouring is subject to considerable variation. Many of the 

 larvEe were lost towards the middle of May, by which date the flowers of the 

 Hemlock were over, and the seeds had ripened and become hard. They utterly 

 refused to eat the leaves of the plant."
