sole cause of the non-red 66 being so greatly in excess. For such 
males may occur, though in a smaller proportion, in the higher parts 
of the Island, e.g., Kandy and Pundaluoya. I am inclined to 
consider that there exists a connection within certain limits between 
the amount of red and the constitution of the male, and to regard 
the ‘‘ red ” males (and probably those of Group Int. I. also) as being 
more intimately connected with the hector form of female, in which 
the lunules are larger than in the other forms. But whether this 
is really so can only be determined by breeding experiments, and 
breeding experiments we must have before we can hope to understand 
more of the nature of the various forms of Papilio polytes. 
APPENDIX. 

In addition to the instances already given of resemblance more 
or less marked between different species of Lepidoptera, I met with 
the following cases which seem of sufficient interest to place on 
record :— 
While at Trincomalee in September I was struck with the scarcity 
of Hesperids. Parata butleri was abundant and Badhamia excla- 
mationis was found occasionally, but outside these two species neither 
my boy nor myself took a single Hesperid. Accordingly, when I 
one day saw in sparse jungle an insect which looked like a Hesperid 
other than the above two species, I devoted my attention to capturing 
it. After some minutes of stalking I succeeded, and found, rather 
to my surprise, that the putative Hesperid was a moth (Ophiusa 
mezentia). In size and general appearance it is not unlike J'agiades 
atticus (Pl. II., figs. 4 and 5). I prefer to leave to others the 
decision as to which in this case is the mimic and which the model. 
On PI. IT., fig. 13, is figured an insect which I took one day in Kandy, 
at the bottom of Lady Horton’s Drive. I netted it as it flew across 
the road, inwardly congratulating myself upon the acquisition of a 
hitherto uncaptured Lycenid. On extracting it from the net my 
first impression was that the antennz were missing. But on looking 
more closely I discovered that it was not a butterfly at all, but a bug 
belonging to the species Hansenia glauca. Here again I will leave 
it to those wlio are more expert than I to pronounce upon which 
is mimic and which is model. 
While hunting P. polytes one day at the edge of the jungle at 
Trincomalee I caught a small dragon fly (Rhyothemis variegata), 
which I took to be a butterfly until I had actually got it within my 
net. In this small species (PI. IT., fig. 17) the proximal parts of both 
fore and hind wings are black, the distal part of either being
