Larva. Head pale, faintly mottled, sutures light yellowish brown, setae long, 

 clypeus margined in front with dark brown ; ocelli five with angular black pigment 

 spots. Body whitish ; tubercles normal, small, the setce short, iv and v superposed 

 subventrally, rather remote. Five pairs of filamentous branched gills on each side 

 on each segment except on head, prothorax and terminal segment ; the mesothorax 

 lacks one pair, the penultimate segment lacks all but one pair, there being just ioo in 

 all. The gills have each from three to five branches with some variation, which 

 Hart tabulates. They increase also in number in the several stages. Hart tabulates 

 six stages, in which the number of branches of the gills of the first four abdominal 

 segments varies from one in stage I to six at maturity. The gills are situated : sub- 

 dorsal anterior, below tubercle i ; subdorsal posterior, above tubercle ii ; subventral 

 anterior, before tubercles iv -|- v ; subventral posterior, behind tubercles iv -j- v ; 

 pedal, behind tubercle vi. Abdominal feet short, normal, the crochets in a wide 

 complete ellipse. 



Pupa. Spiracle-bearing segments broadest, slightly swollen dorsally, tapering 

 gradually to each end. Rather soft bodied, pale-yellowish white, the eyes darker; 

 smooth. Head small with two dehiscent spine-like porrect setse on the vertex. 

 Spiracles of segments 2 to 4 of the abdomen large and conspicuous, borne on round 

 tubercles. Ventral sheath reaching a little beyond end of 7th segment ; 9th segment 

 beneath with a faint elevated line at middle and a small elevation on each side, the 

 anterior margin conspicuously elevated into a broad transverse ridge bearing a row 

 of seven sharp, brownish, short, longitudinal carinse ; a Y-shaped impression beneath.

$ . Inner margin long, outer convjex, not oblique. White ; a marginal yellow 

 band on both wings finely edged with fuscous. On fore wing a fuscous submarginal 

 band ; a discal ringlet with yellow spot below ; a costal bar beyond, joining the ringle 

 and continued inwards and over submedian interspace to margin. Hind wing with 

 two nearly straight fuscous bands. Below the markings repeated faintly. Expanse, 

 15 mm. 



9 • The fore wings are more pointed than the male, the outer margin more 

 oblique. The markings do not differ. Expanse, 22 mm.
