Dr. T. A. Chapman read a paper on Erphia jmlarica, n. sp,, 

 and Ei'fihia stygrip, chiefly in regard to its association with 

 E. einas, in Spain. 



The object of the paper was to bring together our know- 

 ledge, still rather fragmentary, of how E. stygne and E. evias, 

 starting as it were from the Pyrenees, could be traced west 

 into the Cantabrian Sierra, then south to the Sierra, east of 

 Burgos, and further south to the Guadarrama (at La Granja).

How they were in each locality modified so as to closely 

 resemble each other, and were, varying together, more 

 modified as we went further from the Pyrenees. Beyond the 

 Guadarrama, the two species had not been found together; 

 but to the west was found an extremely modified Stygne (at 

 Bejar) and to the east an extremely modified Evias (in the 

 Albarracin district). In most of these localities an unmodi- 

 fied form of Evias occurred at a lower level, and about six 

 weeks earlier in date. 



The paper also described Erebia palarica, a new species 

 from the Cantabrian range, first taken by Mrs. Nicholl in 

 1902. It superficially resembles E. a-thiops, but is nearer to
