LOWER NEIGHBORS OF CART AGO 143 



the Agua Caliente, and was some four miles from Cartago 

 The San Isidro road had the valuable peculiarity of being 

 sandy (most of the others near Cartago being of clay) and 

 consequently remained in good condition when the clay 

 roads were sometimes girth-deep in mud. In some of the 

 fields bordering this road — locally known to the foreign 

 residents as the "Beehive" road — were depressions filled 

 with rich little pools of water throughout the rainy season 

 and which furnished us a number of larvae and exuviae. In 

 September we particularly noted the abundance of a legu- 

 minous plant with yellow flowers and curious appressed 

 stipules — Zornia diphylla — and a pretty Hypericum {H. 

 fastigiatum) in these wet spots. San Isidro itself was but 

 a tiny hamlet, but its surroundings were charming. The 

 hills of the south side of the valley were close to the Tejar 

 and after fording the stream the road climbed at once and 

 forked into two branches. The left fork descended after a 

 few miles to the river level, reforded the Tejar and led back 

 again, through wide grassy lanes bordered with rivulets 

 that proved good collecting ground, to Concepcion de Car- 

 tago. The right fork led directly into the hills. 



Tobosi, another small village, lies in the extreme south- 

 west corner of the valley where the hills close in on all sides 

 except the east. On one side of the road thither a laguna 

 (at times only a swampy place) furnished us another collect- 

 ing ground. While walking to Tobosi on June 20, 1909, 

 P. saw one of those flights or migrations of butterflies so 

 frequently observed in tropical America. 



I had already noticed the great abundance of a certain 

 butterfly {Timetes chiron) of about two inches wing-spread, 

 having on the upper sides of the wings alternate stripes of 

 dark and light brown parallel to the body. The light brown 

 is replaced on the under side by silvery-white, pale violet 

 and light rusty-red. Each hind wing has two tails on its
