MELIT^A ATHALIA. 83 



The ground colour of the back is black, becoming 

 gradually blackish- olive on the sides, the belly olive- 

 brown, the anal flap and also the segmental divisions 

 olive; all the skin is thickly covered with whitish 

 spots that are very slightly raised, giving it a tesse- 

 lated appearance, except that a dorsal stripe of the 

 black ground is left. The spots on the back are some- 

 what transversely oblong, but rather irregular in shape, 

 and are disposed partly in three transverse rows 

 between the spines of one segment and those of the 

 next, and partly round the bases of the spines ; on the 

 sides the spots are rounder and smaller, and are chiefly 

 congregated round the spines and spiracles ; there is a 

 lateral series of three large irregular spots on each 

 segment beneath the spiracles, which almost forms a 

 broadish longitudinal stripe. The head is black, with 

 a transverse whitish stripe just above the mouth, and 

 a group of whitish spots on the crown of each lobe, 

 which, as does the rest of the head, emit fine black 

 bristly hairs ; on the front of the second segment is a 

 narrow, raised, semicircular plate of greyish flesh- 

 colour, also emitting black bristly hairs ; the colour 

 of the spines of the dorsal and subdorsal rows is 

 orange-ochreous, growing whitish at the tips and of 

 the dorsal row also rather pale at the base ; those in 

 the supra- spiracular row are of a paler ochreous tint, 

 with more of their tips whitish ; the three other rows 

 below the spiracles are all whitish ; all the spines are 

 thickly set with straight, short, pointed black bristles 

 at an acute angle, and for the most part each white 

 spot on the body emits a fine, short black hair ; the 

 spiracles are black, ringed with whitish ; the anterior 

 legs black, the ventral prolegs of a pellucid drab colour 

 tipped with darker drab hooks. 



The pupa is half an inch in length, very plump, with 

 the usual angles much rounded oh ; the abdominal 

 rings bear little rounded eminences — traces of the larval 

 spines ; the tip of the abdomen is bent back at nearly 

 a right angle, and there is a slight depression between
