DISTRIBUTION OF THE RHOPALOCERA. 211 



^f. tUctynna. Not uncommon at Pierrefitte, Cirque de Gavarnie, and 

 Cirque de Troumouse (1800-5500 ft.). 



Aviiiinnis euphrosyne. One worn specimen at Gavarnie (5500 ft.). 

 — A. pales. Not uncommon at Gavarnie and Heas (5000-6000 ft.). — • 

 Var. isis. Heas (5500-6500 ft.). — A. dia. Scarce at Pierretitte 

 (1800 ft.). — A. latonia. One specimen at Heas (5000 ft.). — A. aglaia. 

 Abundant and in good condition ; Gorge de Pierrefitte, Gedre, Ga- 

 varnie, Heas (2000-5500 ft.). — A. niohe var. eris. Abundant at 

 Gavarnie, at the base of the Pic de Pimene (5000-5500 ft.). Under 

 side much lighter than in the Alps, and markings more obscure. The 

 type does not occur at all. — A. adippe. Not common; Pierrefitte, 

 St. Sauveur (1800-3000 ft.).— Var. clcodoxa. Gedre (3500 ft.), where 

 it replaces the type. — A. paphia. St. Sauveur (3000 ft.). 



SATYKiDffi (sixteen species). 



Melanaryia (jaJatea. Very abundant and in good condition, except 

 at the lower altitudes ; Valley de Lanedan, Pierrefitte, St. Sauveur, 

 Gedre, Pont de Scia, Port de Gavarnie (1500-5500 ft.). 



Erebia epiphron var. cnssiope. Port de Gavarnie, Heas (5500- 

 6000 ft.).— Var. pyrmaka. Port de Gavarnie, Heas (5500-6000 ft.). 

 Abundant, but local. Intermediate forms between the two varieties 

 are of frequent occurrence, so that it is often a difficult matter to 

 separate them. — E. manto var. cacilia. A small series at Heas, in 

 good condition and apparently only just emerging (5000-5500 ft.). — ■ 

 E. stygne. Exceedingly abundant at Port de Gavarnie, Heas, Chaos 

 de Godre (4500-7500 ft.). This is by far the most common species of 

 Erebia in the Pyrenees, but does not exhibit a great amount of varia- 

 tion, except as regards the ocellation. It is a positive nuisance in 

 some places. — E. melas var. lefebvrei. Common on the summit of the 

 Port de Gavarnie, but very worn (7000-8000 ft.). I think this species 

 is here intermediate between the variety named and the type. — E. 

 tyndanis var. dromus. Very abundant ; Port de Gavarnie, Cirque de 

 Troumouse, Heas (5500-8000 ft.). This insect is a beautiful object 

 when flying, the wings flashing with an iridescence in the bright 

 sunshine like flakes of silver. — E. gorge. One specimen at Heas 

 (6000 ft.). — Var. gorgone. Port de Gavarnie (6000-7500 ft.). A 

 small series, but in good condition. — E. euryale. Heas ; very abun- 

 dant (5500-6500 ft.). — Var. euryaloides. Three specimens of this 

 interesting variety at Heas (5500-6500 ft.). They are quite black and 

 unspotted, and I think they must be identical with the form found in 

 Lapland. I am not aware that it has been recorded from the Pyrenees 

 before. The species varies considerably here in the degree of ocella- 

 tion, the variety named being the extreme form in this respect. 



Satynis alcyone. St. Sauveur, Gedre, Pont de Scia (3000-3500 ft.). 

 A small series, but in good condition. This insect loves to settle upon 

 rocks by the roadside, like most of the other members of the genus. 



Pararge mmra var. adrasta. Exceedingly abundant at Pierrefitte, 

 Gedre, Gavarnie, and Heas (1800-6000 ft.). All the specimens which 

 I took can, I think, be referred to this South European form ; the 

 females most certainly can be. I did not meet with any specimens 

 even at the highest elevations so dark as is the type in the Alps. — P.
