630 Mr. Edward Saunders on 



stones, as well as on a piece of waste ground at one side, 

 attracted many insects, of which a fairly representative 

 collection was made. The elevation is given at 3280 ft. 



July 28. — El Escorial. In the morning ants were col- 

 lected in one of the main streets, and in the afternoon a 

 number of insects were captured by a little stream just 

 above the town, and on the slope of the Sierra. Insects 

 were abundant and varied, and considering the short space 

 of time which was available, a fair number of species were 

 taken. The altitude was about 2900 to 3000 ft. Although 

 rich in insect life the Sierra Guadarrama at El Escorial 

 is not nearly so varied or so attractive as at La Granja. 

 The great expanse of open mountain side was well clothed 

 with plants of many species, but the woods and groves 

 and abundant streams were wanting. 



July 30. — On the return journey one or two insects were 

 taken at Burgos (about 3000 ft.). 



In conclusion I desire to thank Colonel Yerbury for his 

 kindness in naming the Asilidw which were found attack- 

 ing the Aculeates.
