126 CAT0CALA PROMISSA. 



ments are very much covered with freckles of lightish 

 grey, dark grey, and black, some of them so disposed 

 as to faintly indicate dorsal and subdorsal double lines ; 

 on the fifth the back, though pale in front, is clouded 

 behind, while on the sixth, seventh, eighth, and all be- 

 yond the ninth it is rather uniformly covered with fine 

 greenish-grey freckles, forming on each somewhat of a 

 truncated diamond shape, each successively growing 

 paler ; from the sixth to the end of the eighth these 

 diamonds are relieved by the hinder pairs of whitish 

 prominent warts, more or less ringed at their base with 

 dark grey or black ; from these proceed backward to 

 the segmental division short, dark greyish, double lines 

 rather convergent, most strongly denned on the fifth, 

 eleventh, twelfth, and thirteenth; along the sides, 

 from the end of each segment, is a broad-based, some- 

 what wedge shape of the paler ground, flanked below 

 by the lateral whitish wart, from whence a pale sinuous 

 streak ascends a little obliquely forwards, finely and 

 sharply edged below with black like the wart itself ; 

 the dull red oval spiracle, outlined with black, comes 

 close beneath in front of the wart ; the rest of the side 

 is freckled to about the same appearance as the back; 

 the fleshy filaments are pearly white ; the anterior legs 

 pale, and ringed with dark greenish -grey ; the two 

 first ventral pairs are whitish-grey, the third and fourth 

 pairs greyish in front, darker greenish-grey behind, 

 bearing a few black freckles, the anal pair similar; 

 the belly is whitish, with a conspicuous blackish mark 

 on the middle of each segment, viz. a transverse bar 

 between each pair of the anterior legs, a largish round 

 spot on the fifth and sixth segments, a very much 

 larger spot on the seventh, eighth, ninth, and tenth ; 

 on these two last they are elongated transversely to a 

 diamond shape; the spot is round on the eleventh, 

 twelfth, and thirteenth, each smaller in the order men- 

 tioned ; the skin of the head, back, and sides a little 

 rough, the belly smoother, the filaments smooth. 

 The pupa is nearly an inch in length by five-
