on segments 3-7, narrowing at both ends and flanked by a broad, lateral, 

 similarly coloured band running from the front of segment 2 backwards to 

 meet on the dorsum of segment 8, and continued as a dorsal band on to 

 segments 9 and 10, separated by the segment margins ; the bands do not 

 meet in the dorsal line of segment 2 which is black but embraces all the 

 tubercles of that segment which are coloured yellow like it ; also a broad, 

 cream-coloured band on segments 11-14 laterally, beginning in a few spots 

 on segment 10 (hinder margin) and finishing about the middle of anal flap 

 on each side of the shiny dorsal extremity ; all the tubercles are black 

 except those mentioned above as being otherwise ; prologs shiny black on 

 their outer faces at extremities, dull black elsewhere; true legs shiny black; 

 segments 6-10 soiled flesh colour on venter. The osmaterium is light 

 watery indigo-blue, with the main stem and tips of branches more or less 

 transparent. L: 55mm; B: 11 mm. without tubercles; L. of longest 

 tubercles : 4*5 mm. 



Pupa (PI. I, fig. 13a). — The pupa is cylindrical and much resembles a 

 dead bit of stick, broken off short at the top ; or, as it is generally attached 

 to a branch, a dead stump of a secondary branch, sticking out at an angle 

 of 46° from the main one. The head end is shaped and coloured so as to 

 give that impression ; the whole is rough and coloured to represent dead 

 bark. The hinder end is closely applied along the ventral surfaces of 

 segments 10-13, which are concave beneath to receive the surface of the 

 cylindrical branch it is attached to by the strong, dorsally convex, trapeze- 

 shaped cremaster which is again set beneath plentifully with short, strong, 

 red-brown suspensory booklets. The whole pupa is more or less perfectly 

 cylindrical between the bevelled anal end and the " broken-off " fore-end ;■ 

 it is, however, slightly broadened out in the middle and is very slightly 

 constricted about segment 4 where the body-band passes over the surface. 

 The vertices of the head and frons have their dorsal line inclined at an 

 angle of 60° to the longitudinal axis of the pupa ; segment 2 has that line 

 nearly parallel to that axis and is rather long, with both margins straight ; 

 it is flat on dorsum ; the thorax rises nearly absohttely perpendicularly 

 from the hinder margin of segment 2 in its first ^, has the hinder 

 ^ at right angles to this, otherwise parallel to the axis of pupa, or 

 very nearly so, very gradually running down and back to segment 4 ; 

 the dorsal line of segments 4 to 14 is quite parallel to the longitudinal 

 axis ; the front declivity of thorax has the surface very rugose with 

 some deep depressions along the front margin ; the part of pupa con- 

 sisting of the vertex of head and frons is oval in shape, broader than 

 high, with an irregular rugose surface limited by an irregular ridge behind 

 in which are two central depressions, one above the other, the anterior one 

 the larger and deeper ; the ventral line from front to segment 10 is parallel 

 to longitudinal axis; the shoulders are very slightl prominent and rugose.
