60 THE ENTOMOLOGIST § RECORD. 
especially after coridon, and extended from their emergence until they 
had all disappeared; thus 1 was able to put further research work into 
var. roystonensis. I have fully described this new form in a previous 
issue (Hint. Record, vol. xxvi., p. 275), showing how different are its 
characters from those of ab. inaequalis. After examining some 60,000 
coridon my total var. roystonensis amounted to 66 specimens. Coridon 
males were Just emerging on my arrival, and by the third week were 
out in goodly numbers, and one was able to work for aberrations with 
the greatest delight. The first females were seen at the end of the 
third week of July, and they gradually became more in evidence each 
day. By the end of July the males were fully out and certainly in 
abundance. I say abundance, because their numbers here are usually 
so small compared to the great abundance of females, that when you 
do get a goodly number of males it makes you report them in plenty. 
Such was the case this season, and it led me to wonder in what pro- 
portion the females were going to be. They turned out, as I expected, 
in overwhelming numbers. The first ab. sem2-synyrapha was seen at 
the end of July, and this form occurred more freely during mid-August. 
A great number of this form was taken each day, for during my stay 
some 82 collectors were counted, all more or less keen on semi-syngrapha, 
and from nearly all I was able to ascertain their captures each day, 
between them mustering from three to fourteen each, and as each 
captor stayed from one or two days to a week, roughly some 500 seini- 
syngrapha were taken, and many of these bordered on ab. synyrapha, 
the form with almost the whole of the four wings blue. 
When the males were fully out it was a curious sight to see large 
numbers settling on every patch of sheep droppings, but no females 
were thus observed. By mid-August the males were going over, and a 
few stragglers only emerged during the third week, while by the end of 
August all males had disappeared. The weather during the whole of 
August was not conducive to butterflies, very few fine days, thunder- 
storms day after day with brilliant periods of sunshine between. 
August 10th was one of these days, dull and thundery all day. About 
6 p.m. till 7 p.m. a severe thunderstorm broke with a cloud-burst. 
The whole town was flooded in a quarter of an hour; the rain simply 
came down the hills like rivers, as for shelter, an umbrella was of very 
little use, and I had to get under a small plantation of trees. The 
lightning was very severe and of the forked type, and if ever I had the 
“blues’’ I had it then. I must confess I was a “ wee bit frighty,” I 
had to kneel on the ground and bury myself under my umbrella. After 
an hour in this position I was indeed thankful when the storm gave 
over. Iam not sorry now I went through that experience, for directly 
I emerged from my dug-out the sun broke through, and as if by 
magic the clouds vanished and it was the loveliest evening one could 
wish for. I ventured forth, and the sight of “blues” I shall never 
forget, they were hanging about in hundreds, mostly drying their 
wings. Searching for aberrations was commenced in earnest, and 
some beautiful forms were taken. I dropped on three or four roysto- 
nensis in one small spot, then went a good time before I saw any more, 
then I came on another three with a little time in between. I found 
they seemed to occur more in sheltered spots, for during my stay I 
would go nearly a whole day without seeing any, then I would.drop on 
a sheltered spot and get three or four in as many minutes. I was thus
