88 THE BUTTERFLIES OF CEYLON 
Mr. E. E. Green, writing in ‘‘ Spolia Zeylanica,’’ Vol. 
VIII., Part XXX., gives stlhetana and hecabe, and distin- 
guishes them as follows :— 
“ hecabe.—Outer margin of fore wing entire; marginal 
area of costa distinctly black ; lower extremity of black border 
not subtended by yellow. 
« silhetana.—Outer margin of fore wing distinctly crenulate; 
marginal area of costa yellow; lower extremity of black 
border partially subtended by yellow. - 
My objection to this is that I have several hecabe in which 
the basal half of the costal border is yellow, and szlhetana in 
which it is black. Ina variety of si/hetana mentioned later 
it is almost always black. 
Bingham separates the Indian species as follows :—. 
Three spots in base of cell = stlhetana or mooret. 
Two spots in base of cell = hecabe. 
One spot in base of cell = andersont or sart. 
My objection to this is that one or both of the spots in 
hecabe are frequently obsolete in Ceylon specimens. 
My own opinion is that we have three species in Ceylon, 
which, making use of both Green’s and Bingham’s tables, I 
would define as foliows :— 
Three spots in basal half of cell; terminal margin of fore 
wing distinctly crenulate; lower extremity of black border 
of fore wing usually subtended by yellow = silhetana. 
Not more than two spots in cell; if only one, it is usually 
rather indistinct ; terminal margin of fore wing entire ; lower 
extremity of black border of fore wing never subtended by 
yellow = hecabe. 
One very distinct black streak in cell; terminal margin of 
wing entire, or very slightly crenulate; lower extremity of 
black border of fore wing distinctly subtended by yellow = 
rotundalis . 
154. TERIASHECABE. Found in India, Malaya, China, etc. 
Moore also gives hecabeoides and simulata, but these are 
now regarded as varieties only. It is very variable in 
markings and in size, and a dwarf form from 25 to 30 mm.
