86 Dr. G. B. Longstafi’s Notes on the Butterflies 
Concerning &. melampus I wrote to Dr. Dixey at the 
time: “The Tailed Copper (or Hairstreak) first seen at 
Dilkusha, Lucknow, and found commonly here to-day, 
greatly interests me. Not only is it very beautiful, but it 
is surprisingly hard to see, especially when at rest. Then 
the structure of the hind-wing is most strange; posterior 
to the tail (the next interspace but one) a portion of the 
wing nearly circular, with a very obvious fringe of large 
scales, is set at right angles to the plane of the wing and 
to the direction of the veins.” 
According to Schatz and Rober* this “anal lobe” 
occupies the space between the sub-median and inner mar- 
ginal veins; the second anal and third anal of Comstock ; 
1b and le of Meyrick ; but I have not found in these authors 
any allusion to the striking fact that this lobe is quite out 
of the plane of the wing. This omission may be due to 
the fact that the process of setting usually flattens the 
lobe out so that it is hardly seen in cabinet specimens. 
It did not occur to me at the time (and the suggestion 
arrived by letter too late) that the object of this structure 
is possibly to produce the appearance of a head in a non- 
vital part, the tails representing the antennxe. However, 
drawings made at the time strongly bear out the suggestion. 
The resemblance would be still more striking if these 
Lyceenids, ike so many of the family, habitually rest with 
the head downwards. 
In another letter from Benares I said: “ Thorns are not 
specially bad here, only that one does not know the look 
of many thorny plants until too late. But, on the other 
hand, burrs of every sort and kind abound to an incredible 
degree and tangle up the net; much of one’s time is 
spent in freeing net and breeches therefrom.” 
It might have been added that at Benares I first made 
acquaintance (somewhat intimate) with “spear-grass,” 
which is yet more provocative of bad language than 
either thorn or burr. 
Some three miles from Benares, on the way back from 
Sarnath, where Buddha first taught, I found Delias eucharis 
in extreme abundance in a small field of the tall marigold 
which is so much cultivated for the service of the temples.. 
A truly gaudy sight it was to see crowds of these white, 
yellow, and scarlet butterflies upon the orange-coloured 
blossoms.
