264 PEMPELIA CAHNELLA. 



that segment are black, all without any gloss, save a 

 slight glistening on the anal flap ; the beginning of the 

 green lines on the thoracic segments is quite pale, and 

 the subdorsal one is rather conspicuously so ; the 

 dorsal is a straight black line, and from it to the 

 spiracles on either side are four black and five green 

 ragged-edged lines, making a total of nineteen lines 

 from one spiracular region to the other; as the larval 

 growth increases to half an inch and more, the green 

 becomes bluer, then more slaty, and the black lines 

 less and less intense; the dingy green belly has two 

 black lines above the legs, a black ring round each 

 ventral leg, and a ventral black line. 



The last moult produces a skin which seems for a 

 time to be black, but by degrees, as the larva attains 

 its full growth of seven-eighths or nearly an inch in 

 length, traces of the lines reappear without much effect 

 of breaking the general bronzy blackness of the skin ; 

 this is rather rough, with fine transverse wrinkles, 

 and one much deeper subdividing each segment ; the 

 body in front tapers a little from the third segment 

 to the head, and more behind from the tenth to the 

 thirteenth. The second segment and the head having 

 remained deep dull black, begin at the very last to 

 glisten faintly; the papillae are pinkish-grey tipped 

 with black, parts of the mouth being of the same grey 

 colour with a black streak midway across the upper 

 lip ; some parts of the paler lines are drab or dirty 

 whitish on the thoracic segments, but indistinct 

 behind, though the subdorsal is rather more noticeable 

 throughout, as on it are the black tubercular dots 

 minutely ringed with dirty whitish, of which tint also 

 are the minute roundish-oval spiracles, and also the 

 ocellated spot, with its centre black and extra long 

 hair, on the third segment; a fine soft hair of light 

 brown colour proceeds from each tubercular dot, 

 several from the head, the second and anal segments; 

 the ventral legs, light shining pinkish-grey, are 

 fringed with black hooks.
