XYLINA CONFORMIS ( = FURCIFERA). 65 



and tubercular dots bright sulphur-yellow. After 

 this the growth is more rapid, and the colours become 

 paler ; when about three-quarters of an inch long, 

 the colour is olive-brown, and the lines and dots 

 pale yellow, namely, a dorsal stripe of uniform 

 width, a subdorsal stripe rather broader, a fine 

 wavy line between this and a narrow subspiracular 

 line; the tubercular dots arranged in threes on either 

 side the dorsal stripe. At the end of about six or 

 seven weeks the final moult occurs, when the larva is 

 about an inch in length, and with this moult the 

 ground-colour becomes olive-green, and there come 

 some black markings, giving an effect very different 

 from that of the former stages ; and I may observe 

 that it was just at this time that the great mortality 

 occurred, the larva?, which hitherto had seemed to be 

 doing well, now dying off one after another. 



When full-grown, the length is an inch and a half, 

 the figure rather stout in proportion, and cylindrical, 

 except that the head is a trifle narrower than the 

 second segment, which, with the third, also tapers 

 slightly forwards, and that the thirteenth is tapered to 

 the end ; the head is full and rounded at the sides ; the 

 tubercular dots furnished with very small, fine hairs ; 

 the skin smooth and velvety. The ground-colour is 

 olive-brown with a slight trace of green in it, particu- 

 larly on the back; the sides and belly rather paler, 

 having somewhat of a pinkish tinge. The pale yellow 

 dorsal stripe is interrupted by a deep, blackish, freckled 

 patch of the ground-colour, just at the beginning of 

 each segment, which, by its extension backwards on 

 either side, forms the dark boundary of more than 

 half of a blunt diamond-shape of blackish freckles, 

 the area within showing the yellow dorsal stripe but 

 faintly ; this dark freckling, with a deeper suffusion of 

 ground-colour, forms a bar across the back from the 

 hinder tubercular yellow dot on one side to that on 

 the other ; the part behind remaining to complete this 

 irregular diamond- shape is but faintly freckled, and
