ON ORIENTAL ENTOMOLOGY. 131 
the only four species of butterflies I observed there (the others were, one 
Lyczna, and two Vanessze). 
“P.115. Though far be it from me to say a word against the well-known 
Mr. Butler, he is strong in elaborating species—often, I think, needlessly ; 
so that the species of Yphthima observed need not necessarily be new, 
especially as Dr. Walker had collected several specimens. 
“P. 116. May I venture to remark that the suggestion in the 
second paragraph, as to visiting those six localities in successive years, 
is scarcely plain. Owing to the great difference in number of species 
and specimens observable in different years, it would not lead to fair 
comparison, ¢.g., for one person to visit, say Egypt in May one year, and 
Greece in May the next year. The only way would be for a series of 
collectors to visit all those places in the proper seasons in the same year, 
and this should be continued over a series of years, and the results tabulated. 
“P.125. The remarks on Dragon-flies are very interesting. They are one 
of the most ancient and most widely distributed of insects. In the 
Hawaiian Islands (where owing to the 2,000 miles which separate them from 
America, a great obstacle is presented to the migration of fauna of all kinds) 
these Neuroptera form the most important feature of its insects, and those 
islands have many species peculiar. 
“P. 128. The black ants near Damascus, carrying head and tail aloft, are no 
doubt similar to a very beautiful species I observed in December last at Port 
Darwin, Northern Territory of Australia, only, that species was light brown 
and green. Its nest was formed of leaves of shrubs spun together in situ. 
“P. 133. The genus Mutilla of ants is very interesting to me, chiefly owing 
to its being mimicked in Brazil by a Coleopteron. 
“P. 129. Ihave given:lengthy notes in my book, A Year in Brazil, on 
the economic habits of the species of Atta named Cephalotes and Abdominalis. 
“Tam so pressed for time that I must crave forgiveness for this very 
hasty line, but I hope you may deem it of sufficient interest to show to 
Dr. Walker, and present to him my best thanks for bringing before 
our Society so valuable a record of his observations. The only fault I 
can find is that there are no loop-holes for discussion here, and not much 
opportunity for debate. I should have liked some theories advanced, as 
to causes of differentiation, typical forms, etc.” 
From the Rey. A. Fuller, F.E.S. -— 
“ Pallant, Chichester, March 5, 
“ Allow me to thank the Council of the Victoria Institute through you for 
their invitation to be present on Monday evening to hear Dr. Walker’s 
paper. Had I been in London I should certainly have tried to avail myself 
of it. I have read over the proof of the paper kindly forwarded with much 
interest, as it is by such detailed communications the range of species can 
alone be arrived at. Never having been in the East myself, I fear any com- 
ment of mine would be rather beside the question, otherwise I might add a 
note or two to the Swiss localities mentioned by Dr. Walker, for instance :— 
“P. 111. Aporia Crategi. Two on hill-side, first week, August, 1882, 
Pontresina. 
“P. 113. Melita Didyma. Same time and place, moderately common. 
“Argynnis Lathonia.* Four very fresh specimens. Same time and 
place, moderately common. 
* On referring to one of my cabinets I find a specimen of Argynnis 
Lathonia labelled Pontresina, Sept. 16, 1872. I distinctly remember 
catching it beneath the Roseg Hotel, a little way down the road that leads 
to the Roseg glacier.—I’. A. W.
