the white female of which was rare, but the nearly black 

 males were frequent enough at various points near the 

 Puerto amongst gorse and heath. This species has 

 previously been recorded apparently only from the Pyrenees 

 and on the French side. 



Platyptilia isodactyla was common in the bogs near the 

 Puerto, and some larva? were reared from the egg to nearly 

 full-grown, but died of starvation at La Granja. 



Pamassius apollo was seen in many places, but was 

 common on the ddbris from the railway tunnel at about 

 4200 feet. It was rather over (July 11th). 



The abundance of a Psyche larva on certain slopes and 

 pastures at about 6500 to 7000 feet was phenomenal, the 

 cases were very like those of Pachytelia villosella, but are 

 believed to be Amicta febretta ; a number were brought 

 home, but none have been reared, the larvae moult into 

 a colourless instar, preliminary to (hibernation and ?) 

 pupation. One became a pupa. The package containing 

 these larvae was lost on the way home and turned up three 

 weeks later ; it is comforting to attribute our want of 

 success with them to this circumstance, but it is not 

 perhaps certain. Perhaps they meant hibernating, and we 

 may have some still alive doing so. It was a remarkable 

 sight to see forty or fifty of these large cases within 

 a square yard or so, either on the grass or on shrubs of 

 Cytisus purgans ; the larvae did not seem very particular 

 as to what they ate. 



Mecyna polygonalis was one of the commonest moths 

 seen, and varied from having the upper wings very dark, 

 almost black, to pale yellowish, and some specimens 

 were beautifully marked. 



The following is a list of some of the species of 

 Lepidoptera observed at Puerto de Pajares, and it will 

 suffice to show the absence of specially Spanish forms.
