tint extending far above the blue spiracles. The upper edge of this black 

 regiou is irregiihirly dotted with white ; the under side of the body is 

 also black. 



The top and middle of the prothoracic plate is white, divided into two 

 halves by the median line. Tiie dorsal or itpper side of all the segments 

 to the end of the 8th abdominal segment is cream-white. The tubercles 

 are also greenish-white ; each bear 6-7 long setae and one or two cen- 

 tral ones, which are greenish and as long as the body is thick. 



The suranal plate and anal legs greenish-yellow, with black dots and 

 streaks. Thoracic legs chestnut brown : mid-abdominal legs dark 

 green with dark plantae. Mr. Joutel tells me that some of his larvae 

 had au extra sta^re.

I am indebted to Professor Sasaki for the eggs, which hatched at the 

 end of March. 



Larva. — Stage I. Freshly hatched. Length 6 mm. Head large, 

 chestnut red. Body thick, of the general saturnian shape of the larva of 

 Telea, etc., at the same age. Body straw-yellow, with a narrow black 

 and a lateral or subdorsal black stripe, the latter a little narrower than 

 the dorsal stripe ; this dorsal stripe stops at the median tubercle on 

 the 8th abdominal segment, while behind this tubercle is a transverse 

 black line or suture between the 8th and 9th segments. 



The setae or hairs are at first brown, very soon becoming black, 

 but the tubercles at first are all yellow ; afterwards they begin to turn 

 black at the base, the ends remaining yellow ; at the end of the stage 

 they all become black. Thus, when from 24 to 36 hours old, the two 

 dorsal tubercles on the 3d thoracic tubercle become black, as also the 

 median one on the 8th abdominal segment. There is also a black tri- 

 angular patch on the suranal plate, and one on the side of each 

 anal leg. 



The tubercles of the 2d and 3d thoracic segments are very large 

 and conical: the median tubercle of the 8th abdominal segment is 

 double, high ; the two dorsal ones on the 9th segment are high, and the 

 supraspiracular tubercles are prominent. 



In the freshly hatched larva the black dorsal or heart line is heavier 

 and more distinct than in the larva at the end of this stage. 



Cervical plate of the prothoracic segment gamboge-yellow, the front 

 edge around each submedian tubercle whitish.
