dark — black(?). The tubercle arrangement appears to exactly 

 correspond with second skin. 



In an earlier stage there is a lateral subspiracular and 

 spiracular line in addition to the dorsal markings. The skin 

 also has numerous white dots. 



A slight cocoon is made on the top of earth. 



On the 6th February, 1901, all had pupated. 



Pitpa. (Vol. xxxiii., pi. ix., fig. 22.) 



Colour: Reddish; antennae, leg-covers, &c, pale-brown, 

 eye-covers dark- brown, wing-covers brown. 



Length, T 5 F in. From tip of head to tip of wing-cases is 

 fully two-thirds total length of pupa, the posterior third con- 

 stituting abdominal segments 5 to 10. Pupa is thickest at 

 1st, 2nd, and 3rd abdominals, and there is sharp irregular 

 tapering from 7 to 10 ; 9 appears as a large swollen area over- 

 lying 10, which fits into it as if it were a cap, and terminates 

 with two lateral, two central, hooks, with which a very firm 

 hold is taken of the silk in the cocoon. 



The eye-covers are large and prominent ; antennae extend 

 to tips of wing-cases, enclosing legs and proboscis, which also 

 extends to the tips of wing-cases. 



Only the slightest portion of the base of hind-wing cases 

 can be seen at the juncture with post-thorax. Spiracles on 

 1, 2, and 3 are subdorsal, 4 to 8 lateral. All the segments 

 except 8 to 10 are deeply pitted. 



Imagines emerged as follows : On the 25th February, a 

 male ; on the 26th February, a male and a female ; on the 

 28th February, a male* ; on the 2nd March, a male ; and on 

 the 4th March, a female. 



It is not my intention to discuss imaginal structures; 

 indeed, this would not be in keeping with the title of my 

 paper. What I have to say is rather in the nature of inquiry. 



The larval antenna consists of a base, one or two joints, 

 and appendages of a fleshy nature (Plate XIII. , fig. 12). 

 The imaginal antenna consists of scape (base), pedicel (2nd 

 segment), and clavola (segments beyond). The scape is the 

 muscular base and the pedicel is the nervous base, these 

 being more or less simple in external structure (fig. 13). 

 The clavola segments of A. megaspilat't, male, have paired 

 appendages attached to the shaft ventrally, and on this 

 surface the segments are devoid of scales ; dorsally the shaft 

 is thickly protected with scales (figs. 14 and 15). The pecti- 

 nations have no scales, but numerous fine hairs. The clavola 

 segments act as sense-conductors. 



The functions of the larval and imaginal antennae are no 

 doubt similar, and the homology of their respective parts 

 should prove an interesting study. That such is possible is
