CEYLON 
little Yphthima ceylonica was the one really common butterfly at 
Peradeniya. 
In the Gangaruwa Jungle close by I captured a male Melanitis 
ismene of the dry-season form, also, at rest upon a rock, the tiny 
Burnet-moth, Dendrocera quadripunctata, Hmpsn. 
In Lady Blake’s Drive along the opposite bank of the Mahaweli- 
ganga, Terias libythea , Eabr., was not uncommon, but it did not 
occur at Kandy, the specimens of both sexes were of the wet-season 
form. Of T. venata , Moore, I met with but two individuals in Ceylon, 
both wet-season males, one in the gardens, the other in Lady Blake’s 
Drive, not far away. Of the T. hecabe group I got in the Peradeniya 
district sixteen specimens altogether; of these I referred a single 
“ wet ” male to rotundalis, two males—one “ wet,” the other inter¬ 
mediate—to silhetana, the remaining thirteen to hecabe, six of 
them “ dry ” (1 & 5 $), three “ wet ” (2 1 ?), and four intermediate 
(3 <*, 1 ?)• 
It was on Lady Blake’s Drive that a large butterfly proved 
almost too much for both Mr. Green and myself; a Tirumala 
septentrionis , as we thought, eluded us over and over again, though 
it is usually an easy thing to net. At last, after repeated efforts, 
Mr. Green’s superior skill conquered, and to our surprise there was 
in his net Papilio lanheswara, f. dissimilis. Yet I should under¬ 
estimate the power of Mr. Green’s vision if I said that it equalled 
that of the average hawk. This will give some idea of the occasional 
perfection of mimicry. 
A few insects of other orders were taken in what I may call the 
Peradeniya district, but they were neither numerous nor important. 
When I was out with Mr. Green he found a Carabid of the genus 
Coptodera and the Heteromeron, Pseudo-blaps javanus , under stones ; 
the small Lamellicorn, Singhala hindu, was to be got in abundance 
in the flowers of a (?) Cistus ; along with it were Haptoncus pubescens , 
Murray, and the tiny Idaethina orientalis. The Lycid, Lycostomus 
similis , looked very red as it flew to a Mango leaf on which it 
settled. On damp rocks in the shade, near the river, I found several 
Derispia interrumpens, Walk.; 1 it is notable that while Westwood 
called another species of this genus coccinelloides , Walker described 
his species as actually belonging to the genus Coccinella, so like are 
these Heteromera to Lady-birds. 2 The tiny Pentatomids, Coptosoma
