Olivier's description, Encycl. meth., 1811, vin, 178, no. 2, is by 

 no means sufficient to determine the species, which he collected 

 abundantly June 2, on the plains of Troy near the Scamander. 

 The careful description by Rambur, Neur. p. 335, no. 4, is appar- 

 ently, though not so stated, made from Olivier's type, and is en- 

 tirely sufficient to distinguish the species. The three black spots 

 of the anterior margin of the front wings at once separate N. sinuata 

 from the related species. As far as I know this species is the first 

 figured, and by various authors. 



The oldest figure is given by Petiver, Gazoph. Decas vn, pi. 73, 

 f. 11, called (catal. p. 2, no. 169) Libella Smyrnea perelegans, alis 

 infer, angustissimis. There can be no doubt that the figure repre- 

 sents N. sinuata, though the first large marginal spot is not well 

 shown in the right wing, and the basal transversals are black. These 

 transversals are commonly yellow, with short black triangles at 

 base, but two of m}^ specimens have the black triangle going farther 

 up to the costa, nearly as in Petiver's figures. 1 The plate of Pet- 

 iver was published between 1704 and 1710. 



Ruysch, Thesaurus animal, primus, 1710, pi. 1, D. p. 2, Papilio 

 Turcicus versicolor, is a good figure without doubt belonging to 

 N. sinuata. Linnaeus, in Vetensk. Akad. Handling., 1747, p. 176, 

 pi. 6, f. 1 (German transl. p. 196), described a "curious Phryganea," 

 from the Moldau ; the figure proves it was N. sinuata. The copy 

 of the figure in the German translation is not so good as the origi- 

 nal (the antennae are very bad), and the copy in Linne, Syst. 

 Natur., edit. Martin Houttyn, seems to be somewhat doctored in 

 the copy in Syst. Nat., edit. Ph. L. St. Mueller, 1775, pi. 24, f. 13. 

 Perhaps it is not well known that Houttyn's edition contains a 

 number of original figures, some of them important, at least botan- 

 ically. Houttyn is very rare in libraries. I cannot consult the 

 work now, but Mueller's edition is more common and contains a 

 translation of Houttyn and copies of the figures. 



Linnaeus, Syst. Nat. Ed. x, p. 552, no. 3, has established his 

 Panorpa Coa and quotes Hasselquist, Iter, p. 423, for specimens 

 from the islands Stanchio (Coa) and Metellina. Besides he quotes 

 the Phryganea described by himself (N. sinuata) . As Linne's type 

 still exists, it can easily be ascertained if he has combined two 

 species or even three, for in Ed. xn, he quotes specimens from 



ir The determinations and data given here, when different from those in my Hemer. 

 synopsis, may be accepted as corrections; at the time of the publication of the synop- 

 sis I was not able to compare several works.
