disappear with great rapidity, as they settle suddenly with outspread wings on the 
underside of a leaf, where they are quite invisible from above. They are nearly 
always found near water. In Simla, Thyodamas may often be seen at rest on a 
bare quartz rock in mid-stream, its delicately pencilled markings exactly harmonizing 
with the veinings of the stone ” (de Niceville),

Imago. —Male and female. Upperside either pure white (probably wet-season 
brood) or of various shades from white to pale rich yellowish-ochreous (probably dry- 
season brood) ; veins mostly black. Forewing crossed by four irregularly-undulated 
slender black lines, the first line subbasal, second and third medial, the fourth discal and 
sinuous posteriorly, followed by three submarginal parallel lines; interspaces between 
the discal and outer lines, apically, more or less powdery fuliginous-brown or grey, 
with a small, white-centred oval spot between the veins, the lower outer interspaces 
broken by a fuliginous or olive-brown patch, the inner median and submedian spaces 
being more or less bright ochreous and inwardly edged with steel blue, the latter 
centred with three prominent white spots inwardly edged with black ; base of costal 
border brownish-ochreous; a subbasal black line across the cell, a curved line before 
the end, and two discocellular lines, their upper interspaces and a costal patch 
beyond being brownish-ochreous. Hindwing crossed by three medial slender black 
lines, the middle line angulated towards the costa, followed by a broader outer-discal 
black line, outwardly-edged with steel blue, a slender inner-submargina.l wavy line, 
and then by two outer thicker irregular lines, between the outer-discal and inner 
submarginal is a row of elongated oval white spots, which are inwardly-edged with 
black and bordered anteriorly with olivescent-ochreous, and posteriorly with 
yellowish-ochreous; anal lobes, more or less, yellowish-ochreous, or brownish- 
ochreous, irregularly marked with black spots and streaks edged with white; 
abdominal border brownish-ochreous, edged by a black streak at base of costa; tail
