ON ORIENTAL ENTOMOLOGY. 125 
Libellula striolata, Trithemis rubrinervis, and Crocothemis 3. Trithemis 
erythrea, and all at Villa Ciccolani, public gardens, and A meet 
Island of Roda, Cairo and Matareeyeh gardens, Heliopolis. 
Trithemis rubrinervis is not so common as the other two 
species, and, though nearly of the same size and form, has its 
body, if anything, more tapering in shape, is a singularly 
handsome kind, crimson or magenta coloured, with a blue- 
purple stripe down each side. I first saw it on the Island of 
Roda, and afterwards in the gardens of the Villa Ciccolani, as 
good localities as any I know of in Egypt for the capture of 
Neuroptera. The fourth, I regret to say, I was unable to 
obtain, and am, therefore, ignorant of its name. It usually 
flew very rapidly and high overhead, backwards and 
‘forwards, while I was forcing my way through the tall 
flags and thick underwood which fringes a portion of 
the Island of Roda, for the chance of a cast of the 
net. ‘The colour of the body was lavender-blue, like 
that of the male of L. depressa, but in size it exceeded 
Cischna grandis or Anax imperator, and was the largest 
species of any Neuroptera that I have ever seen alive. My 
visit to Athens and its neighbourhood in the latter end of 
May and beginning of June, 1882, must also be mentioned, as 
I then captured two species of Neuroptera, differing from 
Dragon-flies, being either the perfect insects of the Ant lion, 
or else allied to these last. The smaller, and by far the 
commoner of the two, had brown spotted and gauzy fore- 
wings, and the hinder wings much elongated, and very slender, 
in the shape of tails. It abounded everywhere, in the 
Pass of Daphne, the Stadium, Mount Lycabettus, &c., and 
was especially plentiful on the hill of the Acropolis, in the 
immediate vicinity of the Parthenon. Its name is Nemoptera Nemoptera 
coa. Palpares libelluloides is a rarer and much larger insect.“ 
I captured it in the Pass of Daphne, and on the hillside near 
the Throne of Xerxes. Its name, Libelluloides, is, of course, Falpares. 
to be attributed to the fact that in the wide spread of its 
wings and brown spots upon them, if resembles some of the 
Libellulidee—Libellula quadrimaculata in particular. I 
obtained a single specimen of a third kind—viz., Myrmeleon Peruelenn 
seevus—in the vicinity of Belgrade. This last bears a super- ; 
ficial resemblance to the genus Agrion. All these perfect 
insects of the Ant lion, or those species akin to them, have a 
slow, feeble, and wavering flight. The rare occurrence of 
brooks and streams, and likewise the fact that so few of the 
winter torrents are perennial in their flow, may possibly serve 
to account, to some extent, for the paucity of species of 
Neuroptera so noticeable in the East.
