Qq [April, 1902. 



Ovum. — Each female moth appears to lay about 80 eggs. The eggs are sliaped 

 like a very short, squat fircone, pointed at one end, flattened at the other, apparently 

 circular transversely to this axis. The length is 0.30 mm., the greatest width, 

 U'22. No sculpturing of surface is detected, the eggs are white, owing to their 

 granular contents, and are soft and easily deformed. 



Larva.— The full grown larva is, when at rest in its case, about 4 mm. long, 

 and proportionately very broad, about 0-7 mm., though when stretched out it is 

 longer and more slender. 



It looks greenish, according to the amount of material in the alimentary canal, 

 but is otherwise white or nearly colourless, except for the dark smoky colour of the 

 head, true legs, aud plates on the second, third and fourteenth segments (head = 

 first). The surface is covered with minute granular points. The head is about 

 half the width of the body, and largely retractile into the prothorax, the rest of 

 the larva is of fairly equal width, perhaps widest about 7th, 8th, and 9th segments, 

 and thence tapering to 14th ; viewed dorsally there is a series of hairs, one to each 

 segment, projecting laterally, but double on the thoracic segments. 



The back of each abdominal segment from below the spiracle upwards forms 

 a surface, divided into two subsequents by a transverse depression, fading out before 

 reaching the spiracle, and tending to end at the posterior margin of the segment, in 

 the later segments, yielding to the tendency to mark off the spiracular area as a 

 lateral flange. Below the spiracle this area is rounded off by a groove from a 

 lateral flange, which is again marked off from the more strictly ventral area, on 

 which, however, a faint groove marks off flange three, flange one being the spiracular 

 area, continuous with the dorsal area. 



Tubercles I and II are respectively on these two subsegments, rather far from 

 the middle line and from each other, and 11 but very slightly further out than I. 

 These carry small hairs, that on 11 largest and somewhat porrected. The spiracle 

 is well marked, being faintly tinted, circular, apparently not raised above surface. 

 It is towards the anterior margin of segment. Immediately above it is tub. Ill, 

 with short hair. Directly behind it and on exact middle of segment is IV, 

 carrying the long hair seen on dorsal view. At a lower level, about equally distant 

 from IV aud from spiracle is V, not a strong tubercle, and with small hair. On 

 second flange medially is a tubercle with short hair. Below this no tubercle can be 

 detected, except one with moderate hair on anterior external aspect of prolegs, and 

 on site of prolegs on 5, 6, and 11. On 2nd, 3rd, and 4th (thoracic) segments the 

 hair in line with IV is well developed, in 3 and 4 that in line with III. The large 

 plate covering dorsum of prothorax appears to have an anterior and posterior row 

 of hairs, in all six in number on each side, placed, in front row a long and short 

 internally and a long one externally, behind, the short hair accompanies the external 

 long one. On 3 and 4, a short hair appears to accompany III a little above it, and 

 also a short one both in front and behind IV. 



Dorsally, on 4th segment two small tubercles occur close together on line of I 

 and II, whilst on the narrow dark plate on 3 it is difficult to be sure of more than 

 one tubercle on either side. The dark plate covering whole dorsum of 14 carries 

 about 12 hail's on each side, the strongest of these along the hind margin, whilst 

 below are also several strong hairs on what one would call the anal prolegs, except 

 tor the fact that there are none, but their places are taken by two short cylindrical
