no definite proof that it becomes free in dehiscence. The appendages all lie in their 

 proper places, but are displaced so readily that their agglutination is most flimsy, 

 but certainly exists. They spread freely on dehiscence : 2—7, and more slightly 8, 

 abdominal have an abundant dorsal armature of spines covering the whole surface. 

 Their arragement tends to be alternating in successive rows, but irregularly so ; 

 sometimes a direct row of six from front to back of a segment may be counted ; or, 

 again, ten in a decidedly oblique row, each somewhat overlapping the next ; 

 counting as well as one can, sometimes in direct, sometimes in oblique rows, there 

 are 30 — 30 rows across a segment. On 2nd segment they are very decidedly more 

 sparse, and broader and shorter than on the other segments, in agreement with its 

 actual or approximate fixity. They all lie very flatly to the surface, with the sharp 

 point directed backwards. The anal armature consists of two lateral blunt points. 

 From a little below the spiracles the whole ventral aspect is finely spiculate, as well 

 as much of the dorsal areas of 8 — 10. 



The head piece has a strong bristle at the base of each antenna; a large tri- 

 angular piece (with rounded angles) as labrnm, with two bristles at its base on 

 either side, cheek and eye-pieces wide from side to side, but narrow from above 

 down; eye-pieces not separating, in fact the whole pupa coheres on dehiscence, 

 except for the opening for emergence, labium and palpi well developed. Maxilla 

 pointed, rather broader, and rather shorter than labial palpi. Max. palpi very long, 

 extending outwards and returning superficially back as far as edge of maxilla. 

 Dorsal head-piece small, flimsy, triangular, but quite definite. Prothorax a narrow 

 transverse stripe, prothoracic spiracle very large, in a finely speculated area dipping 

 between pro- and ineso-thorax. 



Mesothorax with a small bristle near middle line, and a stronger further out. 

 Metathorax with strong outer bristles, inner very small, sometimes wanting. 1st 

 abdominal small, smooth, without bristles, spines or spicules. It has a good 

 spiracle hidden away beneath hind-wings. Abdominal spiracles, 2, 3, 4, 5, very 

 obvious, circle 7 not too distinct, 8th only a scar. On abdominal segments 2 — 7 

 bristles II and III are very distinct, and III on 8th, none on 9 or 10. 



Below the mouth parts ami between the 1st legs is an unusually wide area 

 occupied by base of 1st (and 2nd) legs. The wings extend to 6th abdominal seg- 

 ment, the 2nd legs a little shorter, and the 3rd rather longer; the abdominal 

 surface is not attached to them, hut is impressed to receive them. The antenna 3 of 

 the female pupa extend nearly to end of wings, in the male to end of pupa, or even 

 just beyond ; they are even less firmly fixed than the other appendages. 



In emerging the pupa breaks through the weak valvular opening of the end of 

 the case, and projects from if, being held during the escape of the moth by the 

 elastic margins of the case, by about the 6th abdominal segment, it remains pro- 

 jecting so afterwards, and, pale and flimsy as it looks, is fairly solid, and maintains 

 its position under some ill-usage, and when removed by any accident from the case 

 maintains its rotundity and expansion as much as is usual in "incomplete" pupa-. 



Imago. — The imago has long antennae, longer in the $ than in the J , 39 — 42 

 joints in the ? , 45 — 46 in the ,? . There are some scales dorsally on the first three 

 joints, but beyond the joints are rather densely clothed all round with rather short 

 dark hairs. A minute transparent spot occurs at one side of each joint about its
