the 7tli abdominal segment. Segments 9 and 10 much 

 narrower than the preceding segments (text-fig, 21, k, p). 



Length 5 mm., width 1'8 mm. Colour of body sea-shell 

 pink (XIV), chitinised parts of head and thorax pale yellow 

 orange (III), with anterior margins of thoracic segments 

 cinnamon rufous (XIV). Ventral aspect of thoracic segments 

 marked with garnet brown (I) on anterior and posterior 

 margin, as also the loops indicating the position of the 

 thoracic legs. 



Head small, rounded, retracted; pigmented eye-spots promi- 

 nent, round, black. Anterior margin of mouth opening 

 thickened. No mouth-parts. Prothorax conical ; anterior 

 margin inflexed, embracing head and projecting beyond it as 

 a cone. Dorsal chitinisation slight, more pronounced on 

 anterior part. Mesothorax only slightly chitinised on its 

 dorsal part, as also the metathorax. No legs or rudiments 

 of such can be distinguished ; their places are indicated by 

 pigmented loops with their openings medial. Abdominal 

 segments 1 to 6 transparent, 7th segment with a fringe of 

 very fine, cream-coloured, woolly hairs near the posterior 

 margin. Eighth abdominal segment short, cylindrical ; 

 9th segment conical, curved ventro-posteriorly, supported 

 dorsally on its cephalic margin by a chitinised edge. Body- 

 wall soft, membranous, transparent. On ventral aspect of 

 the thoracic and abdominal segments the nerve ganglia are 

 plainly visible. 



Adult Male.— The male (PI. XIII, fig. 19) is a pretty little 

 moth, measuring, with wings expanded, about 18 mm. The 

 body is dark, thorax covered with white hairs, antennas flat- 

 tened, dark grey. The wings are translucent white, the 

 upper part of the fore wings black, each with a small black 

 spot a little beyond the centre of the wing. 



In our breeding-cages the males were commonly found in 

 the morning, so they presumably emerge at night. Their 

 habits, such as time and manner of flight, mating, etc., have 

 not been observed. 



For the present, the species is not of any economic impor-
