2 DILOBA OJ1RULEOCEPHALA. 



each segment, a smaller one following rather lower 

 down near the division and touching the spiracular 

 yellow line ; the black spiracle being situated between 

 the two dots ; close beneath the yellow line occurred 

 a black dot followed by another lower down and more 

 behind, and another on each proleg ; the belly was 

 light greyish-green ; a black hair proceeded from each 

 black spot. Skin smooth and rather glistening. 



On the 5th of April, this larva having moulted a 

 second time, came again to me, and on the 6th I 

 figured it. It now measured 6 lines, or 13 mm. long, 

 and of stouter proportion ; the ground colour of the 

 body a deep bluish-grey, the dorsal and spiracular 

 stripes bright yellow, the dorsal widening at the end 

 of each segment, except on the third segment, where it 

 was a transverse bar in the middle ; no yellow on the 

 head nor on the back of the second segment, where 

 the ground was of a paler grey than the rest of the 

 body, as it also was on the thirteenth segment ; the 

 yellow dorsal mark on the twelfth segment was very 

 much broader than on others ; the yellow spiracular 

 stripe was straight at its lower margin and widest at 

 the end of each segment ; the lobes of the head black 

 and glossy, centre part of face between them light grey, 

 marked above the lip with black ; mouth black. The 

 squarish black plate on the second segment was com- 

 posed of four black shining spots run together, but 

 dorsally divided by a fine thread of light grey. The 

 other round black spots of the body appeared velvety 

 from their being covered with short bristly pubescence, 

 and each spot emitted a black hair. Belly leaden-grey 

 with black spots, some of them of smaller size. 



On the 13th of April, after the third moult (which 

 is supposed to have occurred on the 10th — 11th), the 

 length was 15 mm., or nearly five-eighths of an inch, 

 and of stouter proportion, having an elevated trans- 

 verse ridge on the middle of the back of the third 

 segment and another on the twelfth ; the ground colour 

 of the head was greyish- white, likewise the dorsal line
