Ill 



and narrow forwards, the extent of this being from 5'3mm, at the 3rd 

 abdominal segment to 3mm. at the base of the maxillae, and 3*9mm. at 

 the wing-spine. These positions are in a pupa 9*8mm. long, in which 

 the base of the maxillae is l*3mm., the wing-spine 2-Omm., and the 3rd 

 abdominal segment 6'0mm. from the front. In a lateral view, the 

 lower surface is very little rounded from before backwards, all the 

 curvature, except at the extreme ends, being dorsal. At 3-2mm. from 

 the front the height is 4-Omm., it continues the same for l*8mm., then 

 rises to 5mm. at the 3rd abdominal segment; of this 5mm. the ventral 

 line only affords 1-Omm. between the extreme front and back. The 

 wings extend to 8mm. from the front. The face is so bent under that 

 the posterior border of the antennae at the vertex is visible ventrally. 

 The eyes form a distinct depression in one specimen, not in others ; 

 the antennae extend to the end of the wings ; the first leg reaches the 

 antenna, the second is very narrow, and neither much exceeds 2mm. 

 in length ; the maxillae are 3mm. before disappearing between the 

 antennae, which run side by side for 3mm. more to their termination. 

 The general surface is elaborately reticulated with a raised network. 

 It also looks, and is, very hairy. The length of other pupae under 

 observation later is 10mm. to 11mm. Selecting one of 11mm. the 

 transverse diameters are : —

For 8mm. from the front, the ventral median line is nearly straight, 

 and the front flat to the end of the wings and antennae. The abdominal 

 surface, for the remaining 3mm., inclines upwards, at a very slight 

 angle, so that the cremaster, if there were one, would be about 0-6mm. 

 from the surface of attachment. The variation, therefore, of dorso- 

 ventral diameters, is almost entirely dorsal (as, indeed, is the case in 

 most butterflies). The dorso-ventral measurements are similarly: —

These measurements show how the abdomen is very slightly longer 

 than if it were a sphere, to which the thoracic portion is attached in
