containing clear fluid and air, as U largely the case, i.e., between the 

 appendages and the body (abdomen), the dorsum a little darker and 

 more solid-looking, but still very delicate and transparent. The pupa 

 is much larger and narrower than those of the Ruralids (Theclids), 

 and the thorax and abdomen are more continuous in form and outline ; 

 still it has the Lycamid fulness of abdomen (3rd and 4th abdominal 

 segments), and shortness and roundness of segments beyond wings. 

 Length of pupa 10-5mm. Prothorax narrow .and lmm. from front 

 the width is 2mm. The chief width measurements are as follows: — 



lmm. from front of pupa .. 2 "0mm. wide .. Across pro-mesothoracic incision.

On a side view, the waist at the 1st abdominal segment is slight 

 dorsally, but the ventral line is so waved as to make the height here 

 rather less ; the ventral line swells out about 2mm. from front, and 

 again at 6mm., rather before the end of the wings ; the dorsal line 

 swells over the mesothorax and, after an appreciable dip, again over 

 the abdomen ; the highest point is at the 3rd abdominal. The heights 

 are at : —

Laid on a flat surface, the front end of the pupa (labrum) would be 

 about 04mm. from the surface, the waist-hollow about 0*3mm., and 

 the anal extremity about l'Omm. The antenna? meet over the 

 maxillae, about 6mm. from front, and end level with the wings at 

 about 8mm. The surface (except the appendages) is clothed with very 

 short hairs, numerous about the spiracular region (fifteen in the 

 neighbourhood of the 4th abdominal spiracle), sparse elsewhere, about 

 007mm. long, slender, thickening club-fashion to the ends, of a deep 

 red-brown colour. There are numerous minute lenticles round the 

 spiracles, few elsewhere. The general surface has a fine network of 

 faintly brown raised lines, without any indication of the stellate points 

 of the Ruralids (Theclids). There is no trace of a cremastral armature. 

 The antennal ends and the wing-margins adjacent have some very 

 minute brown spots (almost microscopic) that do not interfere with 

 the general appearance of absence of pigmentation; similar spots exist 

 elsewhere on the appendages, wings and thorax. The wings have 

 similar surface-reticulation to the rest of the surface, but it is so faint 

 and colourless that it is difficult to see (in the living pupa). The 

 prothorax is beautifully sculptured ; the net-work is very distinct, and 

 well-coloured, and, in each little spa.ee of the mesh, is placed, centrally, 

 a dark ring or lenticle ; this is so in the spiracular region ; dorsally 

 there are a good many spaces without lenticles. The prothoracic spiracle- 

 cover is a narrow rounded ridge of purplish colour, sculptured with 

 very numerous line pits. The labrum is a, small triangle, less than 

 0'2mm. across, below it the mandibles meet in the middle line for 

 nearly an equal distance; below this is a microscopic area not 

 occupied by the maxilla 1 , perhaps O'Olmm. across, representing the 

 Labium. The first Legs arc very broad against the head, and also very
