490 BRITISH LEPIDOPTERA. 



but, on the thoracic segments, they are fused, leaving a blurred 

 top edging of liver-colour, which h^re suggests a short lateral line, 

 as the dorsal surface of the thoracic segments is fawn-coloured ; 

 these Z-shaped blotches of fawn-colour bear the spiracles which are 

 tall, narrow, upright ovals, jet-black in colour, with a very fine 

 light lavender ring around them, and, outside this a warm buff- 

 coloured edging which is suffused into the ground-colour, the 

 spiracles themselves being slightly recessed from the body-surface. 

 Commencing at the posterior half of the metathoracic segment, and 

 from a large ocellated spot thereon, is a bright fawn-coloured line 

 very suffused at the edges; at the 2nd abdominal segment this 

 lateral line becomes wider, is of a suffused white tint, in which 

 condition it is continued to the centre of the 7th abdominal, where 

 it abruptly ceases, to be, however, almost at once continued of a 

 bright fawn-colour, upwards and backwards to the base of the 

 caudal horn, where it terminates in a fine point. The whitish part 

 of this lateral line is very suffused on its lower edge, and is strongly 

 emphasised by a series of small pure white spots, set in vertical 

 rows, in a broken manner, upon the segmental skinfolds ; these 

 spots are often encircled with a fine buff ring, and stand in colour 

 relief against the ground tint as vividly as small white porcelain 

 beads might do ; they are arranged on each segment, in vertical 

 lines, on the liver-coloured portions which enclose the dorsal triangles 

 of the fawn-tint ; thus, the first line of dots on the 2nd abdominal 

 segment consists of five dots, one above the other, and nearly 

 meeting the dots from the reverse side at the dorsal centre ; the 

 next line of dots on the same segment is shorter and also the 

 following ones, but irregularly, until they merge into the whitish 

 lateral line. It will be understood from this that the ends of these 

 lines of dots on each segment follow the shape of the dome-like 

 marking on the dorsal area ; this they do, but do not cross the 

 boundary of the liver-colour. These dots are found vertically placed 

 on the lateral line, on each segment, from the 2nd to the 7th 

 abdominal segments, but gradually diminish in the altitude they 

 reach on each succeeding segment posteriorly, e.g., the first row 

 on the 2nd abdominal segment consists of five dots, on the next 

 segment there are but four in the first row, in the next but three, 

 the next two, and the remaining two segments that possess dots 

 have but one each in their first row, and only suggestions of 

 others on the subsegments following. The legs and the powerful 

 claspers are of the liver-colour of the lower portions of the larva, 

 the claspers having fulvous edges on the pedal formations ; the 

 legs are not shiny but have a dull gloss on their surface. The ventral 

 surface is shiny and of the soft liver-colour of the lateral coloration ; 

 there is also a slight indication of a very fine suffused lighter- 

 coloured medioventral line. The caudal horn is small, and hangs 

 much like that of the larva of Manduca atropos ; it is of a bright 

 orange-sienna colour, and very shiny ; its surface is roughened by 

 projecting excrescences, and irregularly marked with a few dark 

 dots around its base, its apex is not pointed but finishes bluntly. 

 At the commencement of the lateral line, on each side of the 

 metathoracic segment, is a most gorgeous single ocellated spot of 

 electric bluish sheen that contrast could offer the simple quaker-like
