24 LIFE-HISTORIES OF PTEROPHORIDA! 
PLATYPTILIA GONODACTYLA, SCHIFF, 
Alucita gonoductyla, Schiff. and Den., Schmett. Wien., p. 320 (1775)('). 
Platyptilia gonodactyla, Tutt, Brit. Lep., V, 201-219 (1906)(7) ; Meyr., Rec. 
Ind. Mus., V, 217(°). 
This is a widely-distributed European species which extends into the 
Northern portion of the Indian Region. It has been recorded from Darjiling(*) 
and Rawalpindi(?). 
In Europe the larva feeds on Tussilago farfara. The early stages are 
described at length by Tutt(*), but have not been found in India as yet. 
STENOPTILIA ZOPHODACTYLA, DUP. 
Pterophorus zophodactylus, Duponchel, Hist. Nat., XI, 668, t. 314 f. 4 
(1838)(?). 
Adkinia zophodactylus, Tutt, Brit. Lep., V, 319-334 (1906)(?). 
Stenoptilia zophodactyla, Meyr., Ent. Mo. Mag., 1907, 146 (1907)(°), T. E. S., 
1907, 504 (1908)(*) ; Fletcher, Spol. Zeylan., VI, 10-11, t. E f. 3 (1909(°). 
This is a widely distributed species, known from Central and Southern 
Europe, Asia Minor, Armenia, India, Ceylon, Eastern Australia and Argentina. 
We have specimens from Lunugala (Ceylon), Ootacamund, Bababudin Hills 
(Mysore), Pusa, Peshawar, Abbottabad, Kashmir, Parachinar, Hangu (Kurram 
Valley) and Cherrapunji. 
Very detailed descriptions of the egg, larva and pupa, taken from English 
specimens, are given by Tutt, pages 322-331(?). The following descriptions 
of the larva and pupa were made from Sinhalese specimens :—“‘ The larva, 
at rest and apparently about full-fed, is about 10 mm. long, stout, stoutest 
about third segment and tapering thence gradually. Head pale yellow with 
black ocelli. Colour a pale green, the spiracles narrowly ringed with black ; 
they are situated about half-way up the segments but do not seem raised 
above the skin-surface at all. There is a broad medio-dorsal stripe, purple 
at the edges, but very dark internally. This is narrowly and obscurely edged 
by a narrow whitish-green longitudinal stripe, of a tint slightly paler than the 
ground-colour. Half-way between the lower edge of this stripe and the 
spiracle is a second similar whitish-green stripe, and a third similar stripe 
occurs on the latero-ventral surface at a distance below the spiracle equal 
to that of the second stripe above it. The two latero-dorsal setigerous tubercles 
are situated at a horizontal distance apart equal to about one-third of the 
width of the segment ; the foremost one bears a short black hair, the aftermost 
a similar white hair ; the tubercles themselves are very small and inconspicu- 
ous. Just above the spiracle occurs a short white hair, directed outwards.
