partially developed, but are apparently not used for walking. All the 

 tubercles are very large and prominent, shiny black, and give the larva 

 a very spotted appearance. In the third instar the colour is pale 

 yellowish-grey, the whole surface being dusted with minute black spots. 

 The fifth abdominal has a small black horseshoe mark where the hump 

 should be, but there is very little trace of the latter except that the 

 segment is somewhat swollen on the top. The head, legs, and prolegs 

 are all grey. The tubercles are very small and scarcely perceptible. 

 The lateral fringe is slightly developed. In the fourth instar the 

 ground colour is of ■ a greenish yellow-grey tint, the whole being 

 sprinkled with minute black dots, as in C. niipta, C. electa, etc. The 

 fifth abdominal still has the black horseshoe mark, but very little trace 

 of a hump. The head is yellow, with a red spot on the top of each lobe, 

 a black streak down each side, tapering to the mouth, and several 

 black lines on the face. The legs and prolegs are pinkish-brown. 

 The tubercles are very inconspicuous, pale yellow, the posterior 

 trapezoidals of the eighth and ninth abdominals being somewhat larger. 

 Beneath, the larva is pale greenish -grey, only the third and fourth 

 abdominals having small spots, though one or two other segments 

 have a slight trace of them. In the fifth instar the larva measures 

 from 2-5 — Sin. The head and legs are pinkish-yellow, the head having 

 a dark coloured streak on the top of each lobe ; these thin out down 

 the face ; it is also much suffused with faint black lines. The ground- 

 colour of the body is yellowish-grey, dusted with minute black and 

 brown spots ; these latter are, however, not as prominent as they are 

 in C. niipta and C. electa. The fifth abdominal has a black transverse 

 band, the points of which touch the prolegs on the fifth abdominal. 

 The hump is small and black. The tubercles are all pale yellow, the 

 trapezoidals being somewhat larger. On the eighth abdominal the 

 posteriors form a ridge, which has a black blotch at the rear of it, 

 and there are also traces of the streaks observed in C. electa and C. 

 nupta. The spiracles are well-developed on the first thoracic and 

 abdominal segments, grey in colour, that on the first thoracic, how- 

 ever, being twice as large as the rest, and surrounded by a ring of 

 white. The prolegs are yellow, tinged with purple at the tip. The 

 lateral fringe is pink, and well-developed. Beneath, the larva is 

 greenish-white, with just a trace of pink; the spots are well-developed 

 on the third to seventh abdominals and slightly on the third thoracic. 

 When full fed the larva spins a cocoon similar to that spun by its 

 allies, amongst the leaves of its foodplant but both my larvaj died 

 whilst pupating. 



The imago measures 2-5 — Sin. in expanse. The forewings, head, 

 and thorax are pale whitish-grey, a great deal dusted with black scales, 

 and with numerous indistinct, smoky, irregular bands crossing the 

 wings. The transverse bars on each side of the orbicular are yellow 

 and much indented, with a black edge on the orbicular side. The 

 orbicular itself is black, surrounded by a yellowish, irregular ring, 

 which in its turn is surrounded by black, whilst just beneath it is a pale 

 yellow, oval spot, surrounded by a smoky ring. The hindwings are, 

 however, the special feature of C. frnxini, the ground colour being 

 lilac-llue ; this is, however, confined to a narrow band in the centre 

 of the wing, the outer band being very broad and regular, tapering 

 slightly towards the anal angle, whilst the inner band has extended
