opaque creamy white. Intermediate forms occur until, at the other 

 extreme, the grey portions are quite black-grey, and the abdominal 

 portions also much suffused. Viewed dorsally, too, some individuals 

 have seven longitudinal rows of black spots — the medio-dorsal, two 

 sub-dorsal and two lateral strongly marked, with two other rows (one 

 on each side), betAveen the medio-dorsal and sub-dorsal, of smaller, 

 but still well-defined, spots. In other examples, the two latter rows are 

 somewhat obsolescent, and the spots, forming the other five rows, are 

 considerably less in size. The wing-markings, too, show considerable 

 variation, some being strongly marked with black longitudinal dashes 

 near the costa and outer margin, others being almost devoid of them. 



The pupa is of typical Lyctenid shape. The skin is shiny and 

 roughened with minute points, that give a suspicion of hairs, even 

 under a very low power. Dorsally : The prothorax is prominent, 

 extending frontally much beyond the meso-thorax. The prothoracic 

 spiracle whitish, forming a linear closed lip, in the intersegmental 

 incision. The meso-thorax swollen centrally, with a pronounced 

 median ridge. The meta-thorax and 1st abdominal segment form a 

 waist meduxlly ; the post-thorax ill-developed centrally, but much 

 widened out laterally at the base of the hind-wings, the interseg- 

 mental division between the meso-thorax and meta-thorax forming 

 a curve, convex to the latter. The 2nd-5th abdominal segments 

 gradually swell out, whilst the 6th-10th contract, the latter seg- 

 ments being very narrow longitudinally. The dorsal black spots, 

 arranged on each of the abdominal segments as •.*.* , appear to be 

 slightly depressed and very rough. On the 7th abdominal and following 

 segments the small spot is united with the larger lateral one. On 

 the meta-thorax and 1st abdominal segment the same arrangement 

 holds good, but the central spot is shifted back somewhat, and the 

 outer spots are smaller. On the meso-thorax a modification takes place, 

 and the five characteristic spots are large and arranged thus : .•.•. . 

 Laterally : the prothorax is prominent, the inner margin of the 

 forewing prominent and ridged, the abdominal spiracles on segments 

 1-8, forming a minute, opaque, flesh-coloured, rounded knob, in a 

 tiny saucer-like brown depression, the latter being edged ventrally 

 with a large l)lack spot (similar to the dorsal ones). Vcntrallt/. — There 

 is a very definite head-piece (bounded by the bases of the antennte, the 

 glazed eye, and the bases of the maxilla? and legs), the skin of which is 

 wrinkled transversely. The transverse eye forms a well-defined lunule, 

 conspicuously smooth, and extending from the base of the antenna 

 to the base of the 1st pair of legs. The antennas are segmented, and 

 extend to the apex of the wings. The maxillte extend to about half 

 the length of the antennae, when they disappear. The 1st pair of 

 legs is very short, but wide at the base, the second pair terminates 

 at the point of disappearance of the maxilLiB, but vanishes beneath the 

 first pair at the base. The skin of the wings is roughened, the black 

 markings consisting of longitudinal inter-neural streaks, extending 

 from Poulton's line towards the base, and varying much in length. 

 The wings reach to beyond the front margin of the 5th abdominal 

 segment, the 6th-9th abdominals are reduced ventrally to mere 

 lines. The sexual organs are practically obsolete, being covered by the 

 cremaster and anus, which form a large prominent rounded mass, 

 turned back ventrally, pale brown in colour, and bearing a large
