SIX WEEKS AMONGST HUNGARIAN BUTTERFLIES. O75 
ing the Domogled to steadfastly refuse to go up by any other 
way than that past the Weisses Kreuze ; the path by this route 
is good, the slopes are easy, one is in shade practically all the 
way, and, best of all, the butterflies that affect the mountain are 
there found most abundantly. 
My chief object in working the Domogled was to obtain a 
good series of Neptis lucilla, which is usually abundant there, 
though rare in the Cserna valley; judging by Mr. Jones’s 
experience I ought to have obtained my object in one journey ; 
I did certainly eventually obtain about two dozen fine examples, 
but I made eight ascents for them, during which I calculate 
I climbed not less than 18,000 ft. I suppose the books are right 
in giving the food-plant of this species as Spirea salicifolia, and 
that of N. aceris as Orobus vernus, but I could not see any- 
where at Herculesbad a plant that I should consider a Spirea, 
nor did I ever see a specimen of Neptis aceris near a plant of 
Orobus vernus, which was abundant in certain places there. 
The habits and haunts of both these butterflies are similar, 
except that Neptis aceris rarely rises much above the Cserna 
valley, whilst N. lucilla is scarce until one gets up at least 
1000 ft. Both seem to delight in small clearings in the forest, 
and if one of these is found overgrown with Clematis vitalba or 
bramble, one or two specimens of a Neptis is pretty sure to be 
there sailing slowly round the bushes on motionless wings, 
except for an occasional flap to give impetus, and from time 
to time settling upon some spray or approaching the resting 
place of another specimen, which will thereupon rise and toy or 
fight with the intruder, both soaring to a considerable height, 
then separating, and each proceeding on its way, which did not 
usually take it out of the clearing. Both species not infrequently 
settle on the ground in dry weather, probably for the sake of 
moisture they find there. The flight being so slow would lead 
one to suppose they are easy to capture; this is not so, how- 
ever; the very slowness of the motion leading one to strike in 
advance, and at Neptis lucilla especially I missed quite a number 
of apparently ludicrously easy shots. 
Beyond N. lucilla I did not see much of note on the Domogled ; 
most of the species previously noted in the Cserna valley were 
there in some numbers, and on the peak itself Hrebia medusa 
var. psodea was not infrequent, the males in bad order, the 
females fairly fresh; this species was not confined to the peak, 
one example being netted by Mr. Tylecote a few hundred feet 
above Herculesbad, whilst I found two or three in an alpine 
meadow on the way up the mountain at an altitude of about 
2000 ft. On the peak Melitea trivia was fairly common, and 
still in good condition on June 21st. The Quelle clearing, 
where in most years good insects usually swarm, was an extra- 
ordinary failure, and beyond a few M. maturna, one example of
