ii, 98, no. 7. Iii his Ent. suppl., p.. -208, no. 8, he describes as Pan- 

 orpa halterata a different species, N. Algirica Ramb. 



King, Panorp., p. 94, no. 8, unites N. pallida Oliv. with Forskal's 

 species after examining a type sent by Olivier himself and still in 

 the Berlin Museum. Another type of N. pallida, now in the col- 

 lection of De Selys, is described by Rambur, Neur. p. 335, no. 5, 

 and figured pi. 8, f. 4. Baron De Selys has figured his type, Ann. 

 Soc. Belg., x, pi. 2, f. 4, in natural size, as is stated p. 255. The 

 last figure is of great importance, as Rambur states Preface, p. 

 xvi, that the plate 8 in his work belongs to "plusieurs planches, 

 que je n'ai pas fait faire, et dont l'execution est tres-mauvaise on 

 inexacte." The figure, pi. 8, f. 2, is obviously bad compared with 

 those of De Selys. It seems to represent a female ; De Selys figures 

 a male ; the wings are different and decidedly bad. The dimen- 

 sions of the figure of De Selys are: long. corp. 19mm. ; al. ant. 

 20mm. ; al. post. 47mm. ; long. ant. 16, but the tip must be want- 

 ing, as Rambur says "an moins aussi longnes que les ailes su*- 

 perieures." The descriptions by Oliv., Enc. meth. viii, p. 179, no. 

 5, and Rambur differ very little. Olivier notes a small white ptero- 

 stigma of the anterior wings, and the posterior wings "tres-longues, 

 tres-minces, a peine plus larges vers Pextremite, avec une seule 

 bande large, un peu obscure a quelque distance de l'extremite." 

 Comparing these descriptions and the figure with those byForskfil 

 — alis posticis triclavatis — there can be scarcely a doubt about the 

 distinction of the species. The same view is taken by Westwood, 

 1. c, p. 378 and Rambur. I have never seen a specimen of N. hal- 

 terata Forsk. Rambur described also the female of N. pallida.
