sti'uctuvp than can be at all clearly seen in the livin.t^- pupa. There are 

 distinct antennal lobes extendin,^' down each side of the head, level 

 with their extremities and between them, are lobes that represent the 

 maxilltp and the labium, with palpi fused at its extremity, hardly less 

 distinct than in the J Solenobiid pupa ; basal to the labium is a narrow 

 plate (the labrum), and just above this the clypeal margin, large pieces 

 outside these, and l)asal to the maxilhe, are probably mandibles, their 

 size being great compared with the other parts, which are here as 

 much atrophied as the iiiamlibles alone usually arc. The legs are 

 represented by three pairs of circular pockets, close together and 

 immediately following the head ; the prothoracic plate is ventrally 

 almost evanescent, the other thoracic plates narrow. The wings are 

 represented by small pockets, from edge to edge of the segment, the 

 anterior about 0-2mm. long, the posterior about O'lmm. The prolegs 

 are represented by strong oval chitinous rings. The intersegmental 

 membrane is present between the 1st and 2nd abdominal segments, 

 but appears to be stretched permanently and not functional. Between 

 the 2nd and 3rd abdominals is a functional intersegmental membrane, 

 which overlaps, and so admits of movement here ; certain pits above 

 and below, and so forming the lateral flange, are very distinct. Two 

 small hairs exist on either side dorsal to the wings on the meso- and 

 metatliorax, a line of four across dorsum, on the abdominal segments, 

 the trapezoidal and supraspiracular hairs exist, the trapezoidal being 

 reversed as in the larva, and very near the posterior margin of the 

 segment. No trace of the thoracic spiracles is detected. 



Oniiii. — The eggs are not quite spherical, but about 0-60iiun. in 

 length and 0'52mm. in width, slightly smaller at one end, and flattened 

 at the ends enough to give them a somewhat square look. This 

 appearance may, however, be due in some degree to pressure. As laid 

 in the case they are very difficult to isolate and individualise, nearly as 

 much so as in the case of Hcteriujipm pcnclla, and there appears to be 

 some adhesive material binding them together. It is probably this 

 that removes the wool from the surface of the moth by adhering to it. 

 Female iiiia//(i. — The female moth is very like the pupa in outline 

 and size, as well as colour, but it is distinctly paler. The head and 

 thoracic segments, with dorsal margins of 1st al^dominal, seem to be 

 fused into a solid mass, at least dorsally, but distinguisliable by sepa- 

 rating lines. Dorsally this portion is dark, nearly black, very smooth, 

 polisiied and shining. Ventrally there are dark spots representing 

 eyes, and two small points possibly mandibles (or antenna'?), but the 

 rest of the area is nearly smootli, with no trace of mouth-parts or legs. 

 Ventrally there is a series of brown spots which are evidently nerve 

 ganglia. They are obvious on abdominal segments 2, H, 4, 5, and G, 

 but are hidden on 7 by the clothing of wool. This 7th segment has a 

 gold spiracle, the last, and is clothed with wool, anteriorly nearly all 

 over, laterally for its posterior half, narrowing dorsally so as to be 

 nai row or wanting at the dorsal line. The uncovered portion of the 

 segment is so much telesco})ed into the 8th that the segment appears 

 to be completelyclothed. TheGth segment has a similar clothing of wool, 

 but so nnu-h less in amount as to form rather, perhaps, two ventral 

 and two slighter lateral patches; a trace also occurs on the oth seg- 

 ment. This wool is wavy, closely set, and of a blnish-green colour, so 

 that it mav easily l)e mistaken for a growth of l)lue mould, perhaps
