GUAM ACASTE— SANTA CRUZ 45 1 



Everywhere I went this day lizards of various species and 

 sizes, from three-foot iguanas down, were very abundant 

 and every few minutes a rustling among the dry leaves or 

 weeds meant one of these active reptiles — perfectly harm- 

 less and yet always causing me to turn and look in the di- 

 rection of the sound. 



With Senor Bonilla and Pedro Alfredo Cuendies, an in- 

 telligent schoolboy who fetched water and ran errands for 

 the Commission, we went southwest from Santa Cruz, 

 crossing the Rio Diria, to a more southern part of the Cerro 

 Las Pilas, In a dry brook bed, instead of Gomphoides 

 dragonflies as at the other locality, I found a species of 

 Micrathyria {M . ocellata quicha) which I had not previously 

 taken although, as already related, we subsequently obtained 

 it at Puntarenas. At Cerro Las Pilas both sexes were fairly 

 abundant, sitting on bare twigs of the mostly leafless small 

 trees, and sometimes impossible of capture on account of the 

 interference of the numerous small twigs with the move- 

 ments of the net. Associated with this species were Ery- 

 throdiplax junerea and, rarely, Orthemis levis. I saw no 

 Gomphoides anywhere this day. 



Although we were very little above Santa Cruz, from one 

 spot we had a view of the four volcanoes of Guanacaste at 

 once — Orosi, Rincon de la Vieja, Miravalles and Tenorio, 

 far away of course, but, for the only time in my experience, 

 Orosi was free from clouds and the others had less than I had 

 ever seen. 



Bull's horn thorn was very abundant around Santa Cruz, 

 being found both near the banks of rivers and also In dry 

 places like this cerro. There were at least two species, both 

 tenanted by ants; one {Acacia costaricensis) which we have 

 already mentioned for Alajuela, etc., had a single gland or 

 group of glands on the petiole of the leaf; the other {A. 

 nicoyensis) with glands in raised tubercles on the upper side
