that I have thought it advisable to include the more important refer- 

 ' ences to the species here mentioned. 



The Membracidse were collected from two localities, " La \'alle 

 dc las Papas " and " Almagucr." The former has been well described 

 in Mr. Alexander's paper on the Tipulidx from this region (Journ. 

 N. Y. Ent. Soc, Sept., 1913, XXI : 3, 194) and the latter is mentioned 

 in the same paper as including the village of that name and the 

 " moss " forest on the mountain ridge west of the village. It was in 

 this latter vicinity, on the trail, and at the edge of the forest that 

 most of the membracids were taken. 



The topography of the mountain sides throughout this region as 

 described by Mr. Lloyd is most interesting, in that the forest zone 

 does not begin until an altitude of about 10,000 feet is reached, and 

 extends from that point upward to an altitude of 12,600 feet, above 

 which the peaks are again free from trees to the summit. The ab- 

 sence of forests below the 10,000 feet line has not been explained, 

 but ]\Ir. Lloyd suggests that this area of the mountain sides may not 

 receive the moisture laden winds which are intercepted by the peaks 

 of the western range, while the area above is swept by these winds 

 and is consequently humid and enabled to support vegetation. Both 

 Dr. Allen and Mr. Lloyd have observed that the lower line of the 

 forest seems to vary in altitude with that of the corresponding sum- 

 mits of the costal range, and average from 6,500 to 10,000 feet above 

 the sea level. 



In this forest the vegetation is so overgrown with moss that the 

 plants and trees present a weird appearance, the trunks and branches 

 seeming to be much larger than they really are, on account of the 

 great loads of the moss and epiphytes which they are forced to bear 

 (PI. I, Fig. i). The condition suggests the name "moss" forest, 

 and on the trail through this forest insects were collected by sweep- 

 ing and were taken from low plants and bushes. 



At Almagucr the forest extends almost to the top of the moun- 

 tain. The membracids were found at an altitude of 10,350 feet, just 

 above the line at which the forest begins. Although the camp located 

 at this place was only about thirteen miles from the village, the 

 climatic conditions of the two localities were entirely different due to 

 the difference in altitudes, the village being situated on the side of the 

 range at an altitude of 7,500 feet and being without rain at a time
