132 THE BUTTERFLIES OF CEYLON 
examined 25 ceylonica 9 and 6 egena 9. The usual marking 
in cevlonica is apparently one spot visible above and 2 below, 
but one or more of these are sometimes absent, and I have 
two specimens in which this interspace is quite unspotted. 
In 5 egena 3¢ the interspace is unmarked, but in one specimen 
there is a white spot visible above and below. Personally 
I can find no reliable tests for separating the two forms, 
except by the ground colour when freshly caught, and I 
strongly suspect them to be only seasonal varieties of the 
same insect. 
H. ceylonica I have never taken this myself, but the 
native collectors seem to be able to get the males in any 
quantity at Kandy ; females are apparently scarce. It is also 
common at Ratnapura, and Mr. Hannyngton has sent me a 
specimen from Coorg, which seems to be identical, It is 
distinct, both externally and internally, from H. moored, 
though closely allied 
‘“Numerous at Kandy in the latter part of the year, and 
found at Pundaluoya’”’ (F. M. Mackwood). 
H. egena. This was originally described by Felder from 
‘“‘ Kalupahana, Ceylon,” and I think there can be little doubt 
that this estate was meant. The gentleman who was 
Superintendent then (Mr. R. E, Pineo) told me that 
naturalists used frequently to stop with him on their way to 
collect in the Bintenna country. I have taken it on thé 
estate. 
It is a very local fly, and was formerly always plentiful on 
a Duranta hedge at the bungalow on Blackwood estate, 2 
miles from here. This hedge has now been cut out, but a 
few specimens may still be taken in the garden there, in July- 
August and November-December. I have also taken it on 
the Haldummulla-Horton Plains bridle road, and received 
specimens from Ratnapura. 
It is attracted by Heliotrope blossom. 
219. HALPE DECORATA, 
Peculiar to Ceylon and confined to the wettest zone. I 
have never taken it myself, but have received a lot of males
