THE BUTTERFLIES OF CEYLON 69 
in the quantity and colour of the blue on the upper side. In 
some of my specimens it is reduced to a few blue scales at the 
base of the fore wing, while in others the wings are pale or 
dark blue, with a brown border. 
I have found the pupa on the stem of an Albizzia moluccana. 
The larve are always attended by the large red ant, and the 
perfect insect may be looked for wherever these ants’ nests 
abound. 
I2I. CAMENA DEVA, De N. and E. Pratapa deva, M. 
Found in India, Burma, Java, Philippines, etc. 
A very local insect. For many years past I have always 
been able to find the males basking on one tree (Ficus 
arnothiana) on this estate from April to November. This 
tree grows at the top of a jungle-clad precipice. The female 
is extremely rare and I have only taken four, all on the tea 
on this estate ; it can be easily distinguished from the female of 
Lajuria longinus by the absence of the post-discal black band 
on the upper side of the hind wing. 
I have never seen it in any other locality, nor have the 
native collectors ever brought me a specimen. 
SPINDASIS. This genus has been previously known as 
Aphneus. It is quite the most difficult genus to name, and 
I confess that I am quite unable to hazard a decision as to 
how many species should appear in a Ceylon list. Moore’s 
“Lepidoptera of Ceylon” gives four species: Schistacea, fusca, 
lazularia (= lohita), and ictis. De Nicéville gives schistacea, 
vulcanus, fusca, lohita, zebrinus, ictis, and nubilus ; but he 
thinks that fusca and schistacea are only “‘ varietal forms” 
of vulcanus ; that zebrinus is probably a variety of lohita ; 
and that “ A. nubilus is a varietal form only of A. ictis.” 
He thus reduces our species to three only. Evans gives, 
schistacea, fusca, lohita, ictis, and lilacinus abnormis. “ Lepid- 
optera Indica” gives schistacea, vulcanus, fusca, lohita, zoilus, 
(= zebrinus), greent, minimus, ictis, and lunultfera, 
(= nubilus). 
Every species is variable, some greatly so, and freaks are 
not rare. Something might be done by breeding on a large
