Hagéh,] 286 [January 22, 
IV. Pteronarcys Pictetii Hagen. 
P: Proteus Tictet, Peri, 12851, ploccxix, tet — 6. 
Male in bad condition, having been before m alcohol. 2 
Dark fuscous, spots outside the posterior ocelli dark brown, basal 
border of the antenne narrow, with an obtuse process in the middle ; 
prothorax as broad as the head, sides straight, hind border a little 
arcuated, angles sharp; yellow median line faintly marked; legs 
pale brownish; abdomen dark fuscous, above, in the middle, and be- 
low orange; wings somewhat clouded around the veins, but their 
color is altered by alcohol; sete brown, paler at the base; the ninth 
ventral segment similar to that in P. nobilis, covering the tenth seg- 
ment, but smaller and pale brown; the upper appendages with the 
tip bent upward ; penis as in P. nobilis. 
Female. Similar to the male; wings dirty hyaline, a little smoky 
around some veins, with a small brown pterostigma; the eighth ven- 
tral segment produced in the middle, with a quadrangular notch at 
the tip, forming two triangular teeth. 
Length, with the wings, 45-48 mm; expanse of wings 80-84 
mm. ‘The female is from Pennsylvania, the male was labelled 
Meadville, in the north of Pennsylvania, but this locality is not cer- 
tain, as some of the lot, to which the insect belonged, proved later 
to be from Texas. Iam indebted for the male to Mr. B. P. Mann. 
The female was described in my Synopsis as Pt. regalis and the 
locality given, Philadelphia, belongs only to the specimen. I believe 
to this species belongs a female in alcohol from Minnesota, mentioned 
in my Synopsis as probably Pt. biloba. The vulvar notch is narrower, 
and its angle not so sharp. 
I believe this species is Pictet’s Pt. Proteus ; the locality and the 
size are just the same, and his figure of the male appendages seems 
to agree very well, when viewed from above. I have not seen his 
type, but the darker .apical part of the wings would apply better to 
the Tennessee specimen, which is the only Pteronarcys I have seen 
with the apical part of the hind wings so much darker. 
V. Peteronacys regalis Newman. Entom. Mag., vol. v., 176, 1.

rior ocelli pale brown ; basal border of the antemz broadest in the 
‘middle, making a blunt rounded angle; prothorax broader than the

yellow median line broader at the ends ; antenne and legs dark brown ; 
sete brown, paler at the base; wings grayish hyaline, veins blackish,
